Xml Delphi DLL Reference Documentation

Xml

Current Version: 9.5.0.75

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

Create/Dispose

var
myObject: HCkXml;

begin
myObject := CkXml_Create();

// ...

CkXml_Dispose(myObject);
end;
function CkXml_Create: HCkXml; stdcall;

Creates an instance of the HCkXml object and returns a handle (i.e. a Pointer). The handle is passed in the 1st argument for the functions listed on this page.

procedure CkXml_Dispose(handle: HCkXml); stdcall;

Objects created by calling CkXml_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function.

Properties

Cdata
function CkXml_getCdata(objHandle: HCkXml): wordbool; stdcall;
procedure CkXml_putCdata(objHandle: HCkXml; newPropVal: wordbool); stdcall;

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

More Information and Examples
top
Content
procedure CkXml_getContent(objHandle: HCkXml; outPropVal: HCkString); stdcall;
procedure CkXml_putContent(objHandle: HCkXml; newPropVal: PWideChar); stdcall;
function CkXml__content(objHandle: HCkXml): PWideChar; stdcall;

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
function CkXml_getContentInt(objHandle: HCkXml): Integer; stdcall;
procedure CkXml_putContentInt(objHandle: HCkXml; newPropVal: Integer); stdcall;

Set/get the content as an integer.

top
DebugLogFilePath
procedure CkXml_getDebugLogFilePath(objHandle: HCkXml; outPropVal: HCkString); stdcall;
procedure CkXml_putDebugLogFilePath(objHandle: HCkXml; newPropVal: PWideChar); stdcall;
function CkXml__debugLogFilePath(objHandle: HCkXml): PWideChar; stdcall;

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
procedure CkXml_getDocType(objHandle: HCkXml; outPropVal: HCkString); stdcall;
procedure CkXml_putDocType(objHandle: HCkXml; newPropVal: PWideChar); stdcall;
function CkXml__docType(objHandle: HCkXml): PWideChar; stdcall;

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

EmitBom
function CkXml_getEmitBom(objHandle: HCkXml): wordbool; stdcall;
procedure CkXml_putEmitBom(objHandle: HCkXml; newPropVal: wordbool); stdcall;
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
function CkXml_getEmitCompact(objHandle: HCkXml): wordbool; stdcall;
procedure CkXml_putEmitCompact(objHandle: HCkXml; newPropVal: wordbool); stdcall;
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
function CkXml_getEmitXmlDecl(objHandle: HCkXml): wordbool; stdcall;
procedure CkXml_putEmitXmlDecl(objHandle: HCkXml; newPropVal: wordbool); stdcall;

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
procedure CkXml_getEncoding(objHandle: HCkXml; outPropVal: HCkString); stdcall;
procedure CkXml_putEncoding(objHandle: HCkXml; newPropVal: PWideChar); stdcall;
function CkXml__encoding(objHandle: HCkXml): PWideChar; stdcall;

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
function CkXml_getI(objHandle: HCkXml): Integer; stdcall;
procedure CkXml_putI(objHandle: HCkXml; newPropVal: Integer); stdcall;
Introduced in version 9.5.0.64

top

function CkXml_getJ(objHandle: HCkXml): Integer; stdcall;
procedure CkXml_putJ(objHandle: HCkXml; newPropVal: Integer); stdcall;
Introduced in version 9.5.0.64

function CkXml__lastErrorHtml(objHandle: HCkXml): PWideChar; stdcall;

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
procedure CkXml_getLastErrorText(objHandle: HCkXml; outPropVal: HCkString); stdcall;
function CkXml__lastErrorText(objHandle: HCkXml): PWideChar; stdcall;

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
LastErrorXml
procedure CkXml_getLastErrorXml(objHandle: HCkXml; outPropVal: HCkString); stdcall;
function CkXml__lastErrorXml(objHandle: HCkXml): PWideChar; stdcall;

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
function CkXml_getLastMethodSuccess(objHandle: HCkXml): wordbool; stdcall;
procedure CkXml_putLastMethodSuccess(objHandle: HCkXml; newPropVal: wordbool); stdcall;
Introduced in version 9.5.0.52

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
function CkXml_getNumAttributes(objHandle: HCkXml): Integer; stdcall;

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

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