 TiXmlDocument (const std::string &documentName)
 Constructor.
bool LoadFile (TiXmlEncoding encoding=TIXML_DEFAULT_ENCODING)
 Load a file using the current document value.
bool SaveFile () const
 Save a file using the current document value. Returns true if successful.
bool LoadFile (const char *filename, TiXmlEncoding encoding=TIXML_DEFAULT_ENCODING)
 Load a file using the given filename. Returns true if successful.
bool SaveFile (const char *filename) const
 Save a file using the given filename. Returns true if successful.
bool LoadFile (FILE *, TiXmlEncoding encoding=TIXML_DEFAULT_ENCODING)
 Load a file using the given FILE*.
bool SaveFile (FILE *) const
 Save a file using the given FILE*. Returns true if successful.
bool LoadFile (const std::string &filename, TiXmlEncoding encoding=TIXML_DEFAULT_ENCODING)
bool SaveFile (const std::string &filename) const
 < STL std::string version.
virtual const char * Parse (const char *p, TiXmlParsingData *data=0, TiXmlEncoding encoding=TIXML_DEFAULT_ENCODING)
 Parse the given null terminated block of xml data.
const TiXmlElementRootElement () const
 Get the root element -- the only top level element -- of the document.
bool Error () const
 If an error occurs, Error will be set to true.
const char * ErrorDesc () const
 Contains a textual (english) description of the error if one occurs.
int ErrorId () const
 Generally, you probably want the error string ( ErrorDesc() ).
int ErrorRow () const
 Returns the location (if known) of the error.
int ErrorCol () const
 The column where the error occured. See ErrorRow().
void SetTabSize (int _tabsize)
 SetTabSize() allows the error reporting functions (ErrorRow() and ErrorCol()) to report the correct values for row and column.
void ClearError ()
 If you have handled the error, it can be reset with this call.
void Print () const
 Write the document to standard out using formatted printing ("pretty print").
virtual void Print (FILE *cfile, int depth=0) const
 Print this Document to a FILE stream.
virtual const TiXmlDocumentToDocument () const
 Cast to a more defined type. Will return null not of the requested type.
virtual TiXmlDocumentToDocument ()
 Cast to a more defined type. Will return null not of the requested type.
virtual bool Accept (TiXmlVisitor *content) const
 Walk the XML tree visiting this node and all of its children.

Protected Member Functions

virtual TiXmlNodeClone () const
 Create an exact duplicate of this node and return it.

Detailed Description

Always the top level node.

A document binds together all the XML pieces. It can be saved, loaded, and printed to the screen. The 'value' of a document node is the xml file name.


Member Function Documentation

bool TiXmlDocument::LoadFile ( TiXmlEncoding  encoding = TIXML_DEFAULT_ENCODING  ) 

Load a file using the current document value.

Returns true if successful. Will delete any existing document data before loading.

bool TiXmlDocument::LoadFile ( FILE *  ,
TiXmlEncoding  encoding = TIXML_DEFAULT_ENCODING 
)

Load a file using the given FILE*.

Returns true if successful. Note that this method doesn't stream - the entire object pointed at by the FILE* will be interpreted as an XML file. TinyXML doesn't stream in XML from the current file location. Streaming may be added in the future.

bool TiXmlDocument::LoadFile ( const std::string &  filename,
TiXmlEncoding  encoding = TIXML_DEFAULT_ENCODING 
) [inline]

Parameters:
encoding  STL std::string version.

virtual const char* TiXmlDocument::Parse ( const char *  p,
TiXmlParsingData *  data = 0,
TiXmlEncoding  encoding = TIXML_DEFAULT_ENCODING 
) [virtual]

Parse the given null terminated block of xml data.

Passing in an encoding to this method (either TIXML_ENCODING_LEGACY or TIXML_ENCODING_UTF8 will force TinyXml to use that encoding, regardless of what TinyXml might otherwise try to detect.

Implements TiXmlBase.

const TiXmlElement* TiXmlDocument::RootElement (  )  const [inline]

Get the root element -- the only top level element -- of the document.

In well formed XML, there should only be one. TinyXml is tolerant of multiple elements at the document level.

bool TiXmlDocument::Error (  )  const [inline]

If an error occurs, Error will be set to true.

Also,

int TiXmlDocument::ErrorId (  )  const [inline]

Generally, you probably want the error string ( ErrorDesc() ).

But if you prefer the ErrorId, this function will fetch it.

int TiXmlDocument::ErrorRow (  )  const [inline]

Returns the location (if known) of the error.

The first column is column 1, and the first row is row 1. A value of 0 means the row and column wasn't applicable (memory errors, for example, have no row/column) or the parser lost the error. (An error in the error reporting, in that case.)

SetTabSize, Row, Column

void TiXmlDocument::SetTabSize ( int  _tabsize  )  [inline]

SetTabSize() allows the error reporting functions (ErrorRow() and ErrorCol()) to report the correct values for row and column.

It does not change the output or input in any way.

By calling this method, with a tab size greater than 0, the row and column of each node and attribute is stored when the file is loaded. Very useful for tracking the DOM back in to the source file.

The tab size is required for calculating the location of nodes. If not set, the default of 4 is used. The tabsize is set per document. Setting the tabsize to 0 disables row/column tracking.

Note that row and column tracking is not supported when using operator>>.

The tab size needs to be enabled before the parse or load. Correct usage:

		TiXmlDocument doc;
		doc.SetTabSize( 8 );
		doc.Load( "myfile.xml" );

Row, Column

void TiXmlDocument::ClearError (  )  [inline]

If you have handled the error, it can be reset with this call.

The error state is automatically cleared if you Parse a new XML block.

void TiXmlDocument::Print (  )  const [inline]

Write the document to standard out using formatted printing ("pretty print").

virtual TiXmlNode* TiXmlDocument::Clone (  )  const [protected, virtual]

Create an exact duplicate of this node and return it.

The memory must be deleted by the caller.

Implements TiXmlNode.
