Properties

Cdata
bool get_Cdata(void);
void put_Cdata(bool newVal);

When True, causes an XML node's content to be encapsulated in a CDATA section.

More Information and Examples
Using CDATA in XML
top
Content
void get_Content(CkString &str);
const char *content(void);
void put_Content(const char *ansiOrUtf8Str);

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".

More Information and Examples

ContentInt
int get_ContentInt(void);
void put_ContentInt(int newVal);

Set/get the content as an integer.

top
DebugLogFilePath
void get_DebugLogFilePath(CkString &str);
const char *debugLogFilePath(void);
void put_DebugLogFilePath(const char *ansiOrUtf8Str);

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:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
DocType
void get_DocType(CkString &str);
const char *docType(void);
void put_DocType(const char *ansiOrUtf8Str);

The DOCTYPE declaration (if any) for the XML document.

More Information and Examples
Setting the XML DOCTYPE
top
EmitBom
bool get_EmitBom(void);
void put_EmitBom(bool newVal);
Introduced in version 9.5.0.44

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.

top
EmitCompact
bool get_EmitCompact(void);
void put_EmitCompact(bool newVal);
Introduced in version 9.5.0.64

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.

More Information and Examples
XML EmitCompact
top
EmitXmlDecl
bool get_EmitXmlDecl(void);
void put_EmitXmlDecl(bool newVal);

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 ...".

top
Encoding
void get_Encoding(CkString &str);
const char *encoding(void);
void put_Encoding(const char *ansiOrUtf8Str);

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".

top
I
int get_I(void);
void put_I(int newVal);
Introduced in version 9.5.0.64

Used in tagPaths (and ChilkatPath). The value of this property is substituted for "i" in "[i]". See the example below..

top
IsBase64
bool get_IsBase64(void);
Introduced in version 9.5.0.76

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.

top
J
int get_J(void);
void put_J(int newVal);
Introduced in version 9.5.0.64

Used in tagPaths (and ChilkatPath). The value of this property is substituted for "j" in "[j]". See the example below..

top
K
int get_K(void);
void put_K(int newVal);
Introduced in version 9.5.0.64

Used in tagPaths (and ChilkatPath). The value of this property is substituted for "k" in "[k]". See the example below..

top
LastErrorHtml
void get_LastErrorHtml(CkString &str);
const char *lastErrorHtml(void);

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.

top
LastErrorText
void get_LastErrorText(CkString &str);
const char *lastErrorText(void);

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.

More Information and Examples
Concept of LastErrorTextLastErrorText Standard Information
top
LastErrorXml
void get_LastErrorXml(CkString &str);
const char *lastErrorXml(void);

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.

top
LastMethodSuccess
bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);

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.

top
NumAttributes
int get_NumAttributes(void);

The number of attributes. For example, the following node has 2 attributes: 

<tag attr1="value1" attr2="value2"> This is the content</tag>

More Information and Examples

top
SortCaseInsensitive
bool get_SortCaseInsensitive(void);
void put_SortCaseInsensitive(bool newVal);

If true (or 1 for ActiveX), then all Sort* methods use case insensitive sorting.

top
Standalone
bool get_Standalone(void);
void put_Standalone(bool newVal);

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
void get_Tag(CkString &str);
const char *tag(void);
void put_Tag(const char *ansiOrUtf8Str);

const char *uncommonOptions(void);
void put_UncommonOptions(const char *ansiOrUtf8Str);
Introduced in version 9.5.0.90

top
Utf8
bool get_Utf8(void);
void put_Utf8(bool newVal);

When set to true, all "const char *" arguments are interpreted as utf-8 strings. If set to false (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to true, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to false, all "const char *" return values are ANSI strings.

top
VerboseLogging
bool get_VerboseLogging(void);
void put_VerboseLogging(bool newVal);

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.

  • "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)
