Xml Unicode C Reference Documentation

Xml

Current Version: 10.0.0

A free non-validating XML parser component with encryption and compression features.

Create/Dispose

HCkXmlW instance = CkXmlW_Create();
// ...
CkXmlW_Dispose(instance);
HCkXmlW CkXmlW_Create(void);

Creates an instance of the HCkXmlW object and returns a handle ("void *" pointer). The handle is passed in the 1st argument for the functions listed on this page.

void CkXmlW_Dispose(HCkXmlW handle);

Objects created by calling CkXmlW_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkXmlW_Dispose.

Properties

Cdata
BOOL CkXmlW_getCdata(HCkXmlW cHandle);
void CkXmlW_putCdata(HCkXmlW cHandle, BOOL newVal);

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

More Information and Examples
top
Content
void CkXmlW_getContent(HCkXmlW cHandle, HCkString retval);
void CkXmlW_putContent(HCkXmlW cHandle, const wchar_t *newVal);
const wchar_t *CkXmlW_content(HCkXmlW cHandle);

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".

top
ContentInt
int CkXmlW_getContentInt(HCkXmlW cHandle);
void CkXmlW_putContentInt(HCkXmlW cHandle, int newVal);

Set/get the content as an integer.

top
DebugLogFilePath
void CkXmlW_getDebugLogFilePath(HCkXmlW cHandle, HCkString retval);
void CkXmlW_putDebugLogFilePath(HCkXmlW cHandle, const wchar_t *newVal);
const wchar_t *CkXmlW_debugLogFilePath(HCkXmlW cHandle);

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.

DocType
void CkXmlW_getDocType(HCkXmlW cHandle, HCkString retval);
void CkXmlW_putDocType(HCkXmlW cHandle, const wchar_t *newVal);
const wchar_t *CkXmlW_docType(HCkXmlW cHandle);

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

top
EmitBom
BOOL CkXmlW_getEmitBom(HCkXmlW cHandle);
void CkXmlW_putEmitBom(HCkXmlW cHandle, 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 CkXmlW_getEmitCompact(HCkXmlW cHandle);
void CkXmlW_putEmitCompact(HCkXmlW cHandle, 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
top
EmitXmlDecl
BOOL CkXmlW_getEmitXmlDecl(HCkXmlW cHandle);
void CkXmlW_putEmitXmlDecl(HCkXmlW cHandle, 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 CkXmlW_getEncoding(HCkXmlW cHandle, HCkString retval);
void CkXmlW_putEncoding(HCkXmlW cHandle, const wchar_t *newVal);
const wchar_t *CkXmlW_encoding(HCkXmlW cHandle);

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 CkXmlW_getI(HCkXmlW cHandle);
void CkXmlW_putI(HCkXmlW cHandle, int newVal);
Introduced in version 9.5.0.64

top
IsBase64
BOOL CkXmlW_getIsBase64(HCkXmlW cHandle);
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 CkXmlW_getJ(HCkXmlW cHandle);
void CkXmlW_putJ(HCkXmlW cHandle, int newVal);
Introduced in version 9.5.0.64

LastErrorHtml
void CkXmlW_getLastErrorHtml(HCkXmlW cHandle, HCkString retval);
const wchar_t *CkXmlW_lastErrorHtml(HCkXmlW cHandle);

top
LastErrorText
void CkXmlW_getLastErrorText(HCkXmlW cHandle, HCkString retval);
const wchar_t *CkXmlW_lastErrorText(HCkXmlW cHandle);

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.

top
LastMethodSuccess
BOOL CkXmlW_getLastMethodSuccess(HCkXmlW cHandle);
void CkXmlW_putLastMethodSuccess(HCkXmlW cHandle, 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 CkXmlW_getNumAttributes(HCkXmlW cHandle);
