List of all members.

## Public Member Functions

| TiXmlDocument ()
| Create an empty document, that has no name.
| TiXmlDocument (const char *documentName)
| Create a document with a name. The name of the document is also the filename of the xml.
| 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 (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 TiXmlElement * | RootElement () 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.
const int | ErrorId () const
| Generally, you probably want the error string ( ErrorDesc() ).
int | ErrorRow ()
| Returns the location (if known) of the error.
int | ErrorCol ()
| The column where the error occured. See ErrorRow().
void | SetTabSize (int _tabsize)
| 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.
void | ClearError ()
| If you have handled the error, it can be reset with this call.
void | Print () const
| Dump the document to standard out.
virtual void | Print (FILE *cfile, int depth=0) const
| Print this Document to a FILE stream.

## Protected Member Functions

virtual TiXmlNode * | Clone () 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

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.

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.

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)

const 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 | ( |  | ) | `[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 | ( | const std::string & | filename,
|  | TiXmlEncoding | encoding = TIXML_DEFAULT_ENCODING
| ) | `[inline]`

Parameters:

  encoding | STL std::string version.

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.

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.

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

| 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" );
