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.
TiXmlDocument::TiXmlDocument | ( | ) |
Create an empty document, that has no name.

Walk the XML tree visiting this node and all of its children.

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.

Create an exact duplicate of this node and return it. The memory must be deleted by the caller.

bool TiXmlDocument::Error | ( | ) | const [inline] |
If an error occurs, Error will be set to true. Also,

const char* TiXmlDocument::ErrorDesc | ( | ) | const [inline] |
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 1461 of file tinyxml.h.
{ 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.)

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.

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.

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" );
