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

◆ Accept()

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:

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.

◆ DeepCopy()

void tinyxml2::XMLDocument::DeepCopy ( XMLDocument target) const

Copies this document to a target document. The target will be completely cleared before the copy. If you want to copy a sub-tree, see XMLNode::DeepClone().

NOTE: that the 'target' must be non-null.

◆ DeleteNode()

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

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

◆ ErrorStr()

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

Returns a "long form" error description. A hopefully helpful diagnostic with location, line number, and/or additional info.

◆ HasBOM()

bool tinyxml2::XMLDocument::HasBOM ( ) const
inline

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

◆ LoadFile() [1/2]

XMLError tinyxml2::XMLDocument::LoadFile ( const char *  filename)

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

◆ LoadFile() [2/2]

XMLError tinyxml2::XMLDocument::LoadFile ( FILE *  )

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

NOTE: The file should be opened as binary ("rb") not text in order for TinyXML-2 to correctly do newline normalization.

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

◆ NewComment()

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.

◆ NewDeclaration()

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"?>

◆ NewElement()

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.

◆ NewText()

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.

◆ NewUnknown()

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.

◆ Parse()

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

Parse an XML file from a character string. Returns XML_SUCCESS (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.

◆ Print()

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

◆ RootElement()

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

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

◆ SaveFile() [1/2]

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

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

◆ SaveFile() [2/2]

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_SUCCESS (0) on success, or an errorID.

◆ SetBOM()

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

Sets whether to write the BOM when writing the file.

◆ ShallowClone()

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.

◆ ShallowEqual()

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.
