Properties
Cdata
Procedure Set ComCdata Boolean value
When True, causes an XML node's content to be encapsulated in a CDATA section.
Content
Procedure Set ComContent String value
The content of the XML node. It is the text between the open and close tags, not including child nodes. For example:
<tag1>This is the content</tag1> <tag2><child1>abc</child1><child2>abc</child2>This is the content</tag2>Because the child nodes are not included, the content of "tag1" and "tag2" are both equal to "This is the content".
ContentInt
Procedure Set ComContentInt Integer value
Set/get the content as an integer.
topDebugLogFilePath
Procedure Set ComDebugLogFilePath String value
If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.
This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:
- a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
- the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
- there is an internal problem (bug) in the Chilkat code that causes the hang.
DocType
Procedure Set ComDocType String value
EmitBom
Procedure Set ComEmitBom Boolean value
If True, then emit the BOM (byte order mark, also known as a preamble) for encodings such as utf-8, utf-16, etc. The defautl value is False. This only applies when writing XML files. It does not apply when getting the XML as a string via the GetXml method.
topEmitCompact
Procedure Set ComEmitCompact Boolean value
If True, then GetXml and GetXmlSb emit compact XML. The XML emitted has no unnecessary whitespace, incuding no end-of-lines (CR's and/or LF's). The default value is False, which maintains backward compatibility.
EmitXmlDecl
Procedure Set ComEmitXmlDecl Boolean value
If True, then the XML declaration is emitted for methods (such as GetXml or SaveXml) where the XML is written to a file or string. The default value of this property is True. If set to False, the XML declaration is not emitted. (The XML declaration is the 1st line of an XML document starting with "<?xml ...".
topEncoding
Procedure Set ComEncoding String value
This is the encoding attribute in the XML declaration, such as "utf-8" or "iso-8859-1". The default is "utf-8". This property can be set from any node in the XML document and when set, causes the encoding property to be added to the XML declaration. Setting this property does not cause the document to be converted to a different encoding.
Calling any of the LoadXml* methods causes this property to be set to the charset found within the XML, if any. If no charset is specified within the loaded XML, then the LoadXml method resets this property to its default value of "utf-8".
topI
Procedure Set ComI Integer value
Used in tagPaths (and ChilkatPath). The value of this property is substituted for "i" in "[i]". See the example below..
IsBase64
Returns True if the content contains only those characters allowed in the base64 encoding. A base64 string is composed of characters 'A'..'Z', 'a'..'z', '0'..'9', '+', '/' and it is often padded at the end with up to two '=', to make the length a multiple of 4. Whitespace is ignored.
topJ
Procedure Set ComJ Integer value
Used in tagPaths (and ChilkatPath). The value of this property is substituted for "j" in "[j]". See the example below..
K
Procedure Set ComK Integer value
Used in tagPaths (and ChilkatPath). The value of this property is substituted for "k" in "[k]". See the example below..
topLastBinaryResult
The binary data returned by the last (binary data returning) method called. Only available if Chilkat.Global.KeepBinaryResult is set to True. This provides a means for obtaining large varbinary results in the SQL Server environment (where limitations exist in getting large amounts of data returned by method calls, but where temp tables can be used for binary properties).
topLastErrorHtml
Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.
topLastErrorText
Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.
LastErrorXml
Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.
topLastMethodSuccess
Procedure Set ComLastMethodSuccess Boolean value
Indicate whether the last method call succeeded or failed. A value of True indicates success, a value of False indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:
- Any method that returns a string.
- Any method returning a Chilkat object, binary bytes, or a date/time.
- Any method returning a standard boolean status value where success = True and failure = False.
- Any method returning an integer where failure is defined by a return value less than zero.
Note: Methods that do not fit the above requirements will always set this property equal to True. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.
topLastStringResult
The string return value of the last (string returning) method called. Only available if Chilkat.Global.KeepStringResult is set to True. This provides a means for obtaining large string results in the SQL Server environment (where limitations exist in getting long strings returned by method calls, but where temp tables can be used for string properties).
LastStringResultLen
The length, in characters, of the string contained in the LastStringResult property.
topNumAttributes
The number of attributes. For example, the following node has 2 attributes:
<tag attr1="value1" attr2="value2"> This is the content</tag>
NumChildren
The number of direct child nodes contained under this XML node.
topSortCaseInsensitive
Procedure Set ComSortCaseInsensitive Boolean value
If true (or 1 for ActiveX), then all Sort* methods use case insensitive sorting.
topStandalone
Procedure Set ComStandalone Boolean value
This is the standalone attribute in the XML declaration. This property can be set from any node in the XML document. A value of True adds a standalone="yes" to the XML declaration:
<?xml ... standalone="yes">top
Tag
Procedure Set ComTag String value
TagNsPrefix
Procedure Set ComTagNsPrefix String value
The node's namespace prefix, if present. For example, if the tag is "soapenv:Envelope", then this property will return "soapenv".
TagPath
Returns the path to reach this element from the XML document root. If the caller is the document root, then the empty string is returned.
TagUnprefixed
Procedure Set ComTagUnprefixed String value
The node's tag without the namespace prefix. For example, if the tag is "soapenv:Envelope", then this property will return "Envelope".
TreeId
Each tree (or XML document) has a unique TreeId. This is the ID of the tree, and can be used to determine if two Xml objects belong to the same tree.
topUncommonOptions
Procedure Set ComUncommonOptions String value
This is a catch-all property to be used for uncommon needs. This property defaults to the empty string and should typically remain empty.
topVerboseLogging
Procedure Set ComVerboseLogging Boolean value
If set to True, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is False. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
topVersion
Methods
AccumulateTagContent
Accumulates the content of all nodes having a specific tag into a single result string. SkipTags specifies a set of subtrees to be avoided. The skipTags are formatted as a string of tags delimited by vertical bar characters. All nodes in sub-trees rooted with a tag appearing in skipTags are not included in the result.
Returns null on failure
AddAttribute
Adds an attribute to the calling node in the XML document. Returns True for success, and False for failure.
Returns True for success, False for failure.
AddAttributeInt
AddChildTree
Adds an entire subtree as a child. If the child was a subtree within another Xml document then the subtree is effectively transferred from one XML document to another.
Returns True for success, False for failure.
AddOrUpdateAttribute
Adds an attribute to an XML node. If an attribute having the specified name already exists, the value is updated.
AddOrUpdateAttributeI
Adds an integer attribute to an XML node. If an attribute having the specified name already exists, the value is updated.
topAddStyleSheet
Adds a style sheet declaration to the XML document. The styleSheet should be a string such as:
<?xml-stylesheet href="mystyle.css" title="Compact" type="text/css"?>top
AddToAttribute
Adds an integer amount to an integer attribute's value. If the attribute does not yet exist, this method behaves the same as AddOrUpdateAttributeI.
AddToChildContent
Adds an integer value to the content of a child node.
topAddToContent
Adds an integer amount to the node's content.
topAppendToContent
BEncodeContent
Sets the node's content with 8bit data that is in a specified multibyte character encoding such as utf-8, shift-jis, big5, etc. The data is first B-encoded and the content is set to be the B-encoded string. For example, if called with "Big5"for the charset, you would get a string that looks something like this: "=?Big5?B?pHCtsw==?=". The data is Base64-encoded and stored between the last pair of "?" delimiters. Use the DecodeContent method to retrieve the byte data from a B encoded string.
Returns True for success, False for failure.
topChildContentMatches
Return True if a child at the specified tagPath contains content that matches a wildcarded pattern. Otherwise returns False.
Beginning in version 9.5.0.64, the tagPath can be a tag path. A tag path is a series of tags separated by vertical bar characters. For example: "tagA|tagB|tagC".
topChilkatPath
Follows a series of commands to navigate through an XML document to return a piece of data or update the caller's reference to a new XML document node.
Note: This method not related to the XPath (XML Path) standard in any way.
The pathCmd is formatted as a series of commands separated by vertical bar characters, and terminated with a return-command:
command|command|command|...|returnCommand
A command can be any of the following:
- TagName -- Navigate to the 1st direct child with the given tag.
- TagName[n] -- Navigate to the Nth direct child with the given tag.
- ".." -- Navigate up to the parent.
- "++" -- Navigate to the next sibling. (next/previous sibling feature added in v9.5.0.76)
- "--" -- Navigate to the previous sibling.
- TagName{Content} -- Navigate to the 1st direct child with the given tag having the exact content.
- /T/TagName -- Traverse the XML DOM tree (rooted at the caller) and navigate to the 1st node having the given tag.
- /C/TagName,ContentPattern -- Traverse the XML DOM tree (rooted at the caller) and navigate to the 1st node having the given tag with content that matches the ContentPattern. ContentPattern may use one or more asterisk ('*") characters to represent 0 or more of any character.
- /C/ContentPattern -- Traverse the XML DOM tree (rooted at the caller) and navigate to the 1st node having any tag with content that matches the ContentPattern. ContentPattern may use one or more asterisk ('*") characters to represent 0 or more of any character.
- /A/TagName,AttrName,AttrValuePattern -- Traverse the XML DOM tree (rooted at the caller) and navigate to the 1st node having the given tag, and attribute, with the attribute value that matches the AttrValuePattern. AttrValuePattern may use one or more asterisk ('*") characters to represent 0 or more of any character.
- * -- Return the Content of the node.
- (AttrName) -- Return the value of the given attribute.
- $ -- Update the caller's internal reference to be the node (arrived at by following the series of commands). Returns an empty string.

- "ContentTrimEnds" - Same as AttrTrimEnds but for content.
- "ContentTrimInside" - Same as AttrTrimInside but for content.
- "LowercaseAttrs" - Convert all attribute names to lowercase.
- "LowercaseTags" - Convert all tags to lowercase.
- "RemoveCtrl" - Remove non-printable us-ascii control chars (us-ascii values <= 31 except for TAB,CR, and LF are removed)
If you have other ideas for useful XML scrubbing directives, send email to [email protected]. It must be general enough such that many developers will find it useful.
SearchAllForContent
Returns the first node having content matching the contentPattern. The contentPattern is a case-sensitive string that may contain any number of '*'s, each representing 0 or more occurrences of any character. The search is breadth-first over the sub-tree rooted at the caller. A match is returned only after the search has traversed past the node indicated by afterPtr. To find the 1st occurrence, set afterPtr equal to null. (For the ActiveX implementation, the afterPtr should never be null. A reference to the caller's node should be passed instead.)
To iterate over matching nodes, the returned node can be passed in afterPtr for the next call to SearchAllForContent, until the method returns null.
Returns null on failure
SearchAllForContent2
Same as SearchAllForContent except the internal reference of the caller is updated to point to the search result (instead of returning a new object).

The valuePattern is a case-sensitive string that may contain any number of '*'s, each representing 0 or more occurrences of any character. The search is breadth-first over the sub-tree rooted at the caller. A match is returned only after the search has traversed past the node indicated by afterPtr. To find the 1st occurrence, set afterPtr equal to null. (For the ActiveX implementation, the afterPtr should never be null. A reference to the caller's node should be passed instead.)
To iterate over matching nodes, the returned node can be passed in afterPtr for the next call to SearchForAttribute, until the method returns null.

To iterate over matching nodes, the returned node can be passed in afterPtr for the next call to SearchForTag, until the method returns null.
Returns null on failure
SearchForTag2
Same as SearchForTag except the internal reference of the caller is updated to point to the search result (instead of returning a new object).
Returns True for success, False for failure.
SetBinaryContent
Sets the node's content to a block of binary data with optional Zip compression and/or AES encryption. The binary data is automatically converted to base64 format whenever XML text is generated. If the zipFlag is True, the data is first compressed. If the encryptFlag is True, the data is AES encrypted using the Rijndael 128-bit symmetric-encryption algorithm.
Returns True for success, False for failure.
topSetBinaryContentFromFile
Sets the node's content with binary (or text) data from a file. The file contents can be Zip compressed and/or encrypted, and the result is base-64 encoded.
Returns True for success, False for failure.
topSortByAttribute
Sorts the direct child nodes by the value of a specified attribute.
topSortByAttributeInt
Sorts the direct child nodes by the value of a specified attribute interpreted as an integer (not lexicographically as strings).
topSortByContent
SortByTag
SortRecordsByAttribute
Sorts the direct child nodes by the content of an attribute in the grandchild nodes.
topSortRecordsByContent
Sorts the direct child nodes by the content of the grandchild nodes.
SortRecordsByContentInt
Sorts the direct child nodes by the content of the grandchild nodes. For sorting purposes, the content is interpreted as an integer (not lexicographically as for strings).
topSwapNode
Swaps another node's tag, content, and attributes with this one.
Returns True for success, False for failure.
topSwapTree
Swaps another node's tag, content, attributes, and children with this one.
Returns True for success, False for failure.
topTagContent
Returns the content of the 1st node found in the sub-tree rooted at the caller that has a given tag. (Note: The search for the node having tag ARG is not limited to the direct children of the caller.)
Returns null on failure
topTagEquals
Returns True if the node's tag equals the specified string.
topTagIndex
Returns the index of the XML node with the given tag. Returns -1 if no node having the specified tag is found at the tagPath.
TagNsEquals
Returns True if the node's tag namespace prefix equals the specified ns.
TagUnpEquals
Returns True if the node's unprefixed tag equals the specified string. For example, if the tag is "soapenv:Body", the unprefixed tag is "Body".
UnzipContent
Unzip the content of the XML node replacing it's content with the decompressed data.
Returns True for success, False for failure.
UnzipTree
Unzips and recreates the XML node and the entire subtree, restoring it to the state before it was zip compressed.
Returns True for success, False for failure.
UpdateAt
Updates the content for the node indicated by tagPath. If autoCreate is True, then nodes along tagPath are auto-created as needed.
UpdateAttrAt
Updates or adds the attribute value for the node indicated by tagPath. If autoCreate is True, then nodes along tagPath are auto-created as needed.
UpdateAttribute
Adds an attribute to the node if it doesn't already exist. Otherwise it updates the existing attribute with the new value.
Returns True for success, False for failure.
UpdateAttributeInt
Updates an attribute value. (Call UpdateAttribute if the attribute value is a string.)
Returns True for success, False for failure.
topUpdateChildContent
Replaces the content of a child node. The tagPath can be a tag or tag path.
Beginning in version 9.5.0.64, the tagPath can be a tag path. A tag path is a series of tags separated by vertical bar characters. For example: "tagA|tagB|tagC". The nodes in the tagPath are automatically created as needed.
UpdateChildContentInt
Replaces the content of a child node where the content is an integer. The tagPath can be a tag or tag path.
Beginning in version 9.5.0.64, the tagPath can be a tag path. A tag path is a series of tags separated by vertical bar characters. For example: "tagA|tagB|tagC".
topZipContent
Applies Zip compression to the content of an XML node and replaces the content with base64-encoded compressed data.
Returns True for success, False for failure.
ZipTree
Zip compresses the content and entire subtree rooted at the calling XML node and replaces the current content with base64-encoded Zip compressed data. The node and subtree can be restored by calling UnzipTree. Note that the node name and attributes are unaffected.
Returns True for success, False for failure.
