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.

bool TiXmlDocument::Error ( ) const

inline

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

• The ErrorId() will contain the integer identifier of the error (not generally useful)
• The ErrorDesc() method will return the name of the error. (very useful)
• The ErrorRow() and ErrorCol() will return the location of the error (if known)

int TiXmlDocument::ErrorId ( ) const

inline

Generally, you probably want the error string ( ErrorDesc() ). But if you prefer the ErrorId, this function will fetch it.

Definition at line 1467 of file tinyxml.h.

References errorId.

{ return errorId; }

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.)

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" );
