Detailed Description

A Document binds together all the functionality. It can be saved, loaded, and printed to the screen. All Nodes are connected and allocated to a Document. If the Document is deleted, all its Nodes are also deleted.

Member Function Documentation

virtual bool tinyxml2::XMLDocument::Accept ( XMLVisitor *  visitor ) const

virtual

Accept a hierarchical visit of the nodes in the TinyXML-2 DOM. Every node in the XML tree will be conditionally visited and the host will be called back via the XMLVisitor interface.

This is essentially a SAX interface for TinyXML-2. (Note however it doesn't re-parse the XML for the callbacks, so the performance of TinyXML-2 is unchanged by using this interface versus any other.)

The interface has been based on ideas from:

• http://www.saxproject.org/
• http://c2.com/cgi/wiki?HierarchicalVisitorPattern

Which are both good references for "visiting".

An example of using Accept():

XMLPrinter printer;
tinyxmlDoc.Accept( &printer );
const char* xmlcstr = printer.CStr();

Implements tinyxml2::XMLNode.

void tinyxml2::XMLDocument::Clear

(

)

Clear the document, resetting it to the initial state.

void tinyxml2::XMLDocument::DeleteNode ( XMLNode *  node )

inline

Delete a node associated with this document. It will be unlinked from the DOM.

bool tinyxml2::XMLDocument::Error ( ) const

inline

Return true if there was an error parsing the document.

XMLError tinyxml2::XMLDocument::ErrorID ( ) const

inline

Return the errorID.

const char* tinyxml2::XMLDocument::GetErrorStr1 ( ) const

inline

Return a possibly helpful diagnostic location or string.

const char* tinyxml2::XMLDocument::GetErrorStr2 ( ) const

inline

Return a possibly helpful secondary diagnostic location or string.

bool tinyxml2::XMLDocument::HasBOM ( ) const

inline

Returns true if this document has a leading Byte Order Mark of UTF8.

char* tinyxml2::XMLDocument::Identify	(	char *	p,
		XMLNode **	node
	)

XMLError tinyxml2::XMLDocument::LoadFile

(

const char *

filename

)

Load an XML file from disk. Returns XML_NO_ERROR (0) on success, or an errorID.

XMLError tinyxml2::XMLDocument::LoadFile

(

FILE *

)

Load an XML file from disk. You are responsible for providing and closing the FILE*.

Returns XML_NO_ERROR (0) on success, or an errorID.

XMLComment* tinyxml2::XMLDocument::NewComment

(

const char *

comment

)

Create a new Comment associated with this Document. The memory for the Comment is managed by the Document.

XMLDeclaration* tinyxml2::XMLDocument::NewDeclaration

(

const char *

text = 0

)

Create a new Declaration associated with this Document. The memory for the object is managed by the Document.

If the 'text' param is null, the standard declaration is used.:

    <?xml version="1.0" encoding="UTF-8"?>

XMLElement* tinyxml2::XMLDocument::NewElement

(

const char *

name

)

Create a new Element associated with this Document. The memory for the Element is managed by the Document.

XMLText* tinyxml2::XMLDocument::NewText

(

const char *

text

)

Create a new Text associated with this Document. The memory for the Text is managed by the Document.

XMLUnknown* tinyxml2::XMLDocument::NewUnknown

(

const char *

text

)

Create a new Unknown associated with this Document. The memory for the object is managed by the Document.

XMLError tinyxml2::XMLDocument::Parse	(	const char *	xml,
		size_t	nBytes = (size_t)(-1)
	)

Parse an XML file from a character string. Returns XML_NO_ERROR (0) on success, or an errorID.

You may optionally pass in the 'nBytes', which is the number of bytes which will be parsed. If not specified, TinyXML-2 will assume 'xml' points to a null terminated string.

void tinyxml2::XMLDocument::Print

(

XMLPrinter *

streamer = 0

)

const

Print the Document. If the Printer is not provided, it will print to stdout. If you provide Printer, this can print to a file:

XMLPrinter printer( fp );
doc.Print( &printer );

Or you can use a printer to print to memory:

XMLPrinter printer;
doc.Print( &printer );
// printer.CStr() has a const char* to the XML

void tinyxml2::XMLDocument::PrintError

(

)

const

If there is an error, print it to stdout.

bool tinyxml2::XMLDocument::ProcessEntities ( ) const

inline

XMLElement* tinyxml2::XMLDocument::RootElement ( )

inline

Return the root element of DOM. Equivalent to FirstChildElement(). To get the first node, use FirstChild().

const XMLElement* tinyxml2::XMLDocument::RootElement ( ) const

inline

XMLError tinyxml2::XMLDocument::SaveFile	(	const char *	filename,
		bool	compact = false
	)

Save the XML file to disk. Returns XML_NO_ERROR (0) on success, or an errorID.

XMLError tinyxml2::XMLDocument::SaveFile	(	FILE *	fp,
		bool	compact = false
	)

Save the XML file to disk. You are responsible for providing and closing the FILE*.

Returns XML_NO_ERROR (0) on success, or an errorID.

void tinyxml2::XMLDocument::SetBOM ( bool  useBOM )

inline

Sets whether to write the BOM when writing the file.

void tinyxml2::XMLDocument::SetError	(	XMLError	error,
		const char *	str1,
		const char *	str2
	)

virtual XMLNode* tinyxml2::XMLDocument::ShallowClone ( XMLDocument *  document ) const

inlinevirtual

Make a copy of this node, but not its children. You may pass in a Document pointer that will be the owner of the new Node. If the 'document' is null, then the node returned will be allocated from the current Document. (this->GetDocument())

Note: if called on a XMLDocument, this will return null.

Implements tinyxml2::XMLNode.

virtual bool tinyxml2::XMLDocument::ShallowEqual ( const XMLNode *  compare ) const

inlinevirtual

Test if 2 nodes are the same, but don't test children. The 2 nodes do not need to be in the same Document.

Note: if called on a XMLDocument, this will return false.

Implements tinyxml2::XMLNode.

virtual XMLDocument* tinyxml2::XMLDocument::ToDocument ( )

inlinevirtual

Safely cast to a Document, or null.

Reimplemented from tinyxml2::XMLNode.

virtual const XMLDocument* tinyxml2::XMLDocument::ToDocument ( ) const

inlinevirtual

Reimplemented from tinyxml2::XMLNode.

Whitespace tinyxml2::XMLDocument::WhitespaceMode ( ) const
