Detailed Description

The parent class for everything in the Document Object Model.

(Except for attributes). Nodes have siblings, a parent, and children. A node can be in a document, or stand on its own. The type of a TiXmlNode can be queried, and it can be cast to its more defined type.

Member Enumeration Documentation

◆ NodeType

The types of XML nodes supported by TinyXml.

(All the unsupported types are picked up by UNKNOWN.)

Definition at line 462 of file tinyxml.h.

Member Function Documentation

◆ Accept()

virtual bool TiXmlNode::Accept ( TiXmlVisitor visitor) const
pure virtual

Accept a hierchical visit the nodes in the TinyXML DOM.

Every node in the XML tree will be conditionally visited and the host will be called back via the TiXmlVisitor interface.

This is essentially a SAX interface for TinyXML. (Note however it doesn't re-parse the XML for the callbacks, so the performance of TinyXML 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():

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

Implemented in TiXmlDocument, TiXmlUnknown, TiXmlDeclaration, TiXmlText, TiXmlComment, and TiXmlElement.

Referenced by TiXmlElement::Accept(), and TiXmlDocument::Accept().

◆ Clear()

void TiXmlNode::Clear ( )

Delete all the children of this node. Does not affect 'this'.

Definition at line 191 of file tinyxml.cpp.

Referenced by TiXmlDocument::LoadFile().

◆ Clone()

virtual TiXmlNode* TiXmlNode::Clone ( ) const
pure virtual

Create an exact duplicate of this node and return it.

The memory must be deleted by the caller.

Implemented in TiXmlUnknown, TiXmlDeclaration, TiXmlComment, and TiXmlElement.

Referenced by InsertAfterChild(), InsertBeforeChild(), InsertEndChild(), and ReplaceChild().

◆ FirstChild() [1/3]

const TiXmlNode* TiXmlNode::FirstChild ( ) const
inline

The first child of this node. Will be null if there are no children.

Definition at line 522 of file tinyxml.h.

Referenced by TiXmlElement::Accept(), TiXmlDocument::Accept(), FirstChild(), FirstChildElement(), TiXmlElement::GetText(), IterateChildren(), TiXmlDocument::Print(), TiXmlPrinter::VisitEnter(), and TiXmlPrinter::VisitExit().

◆ FirstChild() [2/3]

const TiXmlNode * TiXmlNode::FirstChild ( const char *  value) const

The first child of this node with the matching 'value'.

Will be null if none found.

Definition at line 379 of file tinyxml.cpp.

References Value().

◆ FirstChild() [3/3]

TiXmlNode* TiXmlNode::FirstChild ( const char *  _value)
inline

The first child of this node with the matching 'value'. Will be null if none found.

Definition at line 526 of file tinyxml.h.

References FirstChild().

◆ FirstChildElement() [1/2]

const TiXmlElement * TiXmlNode::FirstChildElement ( ) const

Convenience function to get through elements.

Definition at line 470 of file tinyxml.cpp.

References FirstChild(), NextSibling(), and ToElement().

Referenced by TiXmlDocument::RootElement().

References FirstChild(), NextSibling(), and ToElement().

◆ GetDocument()

const TiXmlDocument * TiXmlNode::GetDocument ( ) const

Return a pointer to the Document this node lives in.

Returns null if not in a document.

Definition at line 530 of file tinyxml.cpp.

References ToDocument().

Referenced by InsertAfterChild(), InsertBeforeChild(), InsertEndChild(), LinkEndChild(), and ReplaceChild().

◆ InsertAfterChild()

TiXmlNode * TiXmlNode::InsertAfterChild ( TiXmlNode afterThis,
const TiXmlNode addThis 
)

Add a new node related to this.

Adds a child after the specified child. Returns a pointer to the new object or NULL if an error occured.

Definition at line 282 of file tinyxml.cpp.

References Clone(), GetDocument(), and Type().

◆ InsertBeforeChild()

TiXmlNode * TiXmlNode::InsertBeforeChild ( TiXmlNode beforeThis,
const TiXmlNode addThis 
)

Add a new node related to this.

Adds a child before the specified child. Returns a pointer to the new object or NULL if an error occured.

Definition at line 250 of file tinyxml.cpp.

References Clone(), GetDocument(), and Type().

◆ InsertEndChild()

TiXmlNode * TiXmlNode::InsertEndChild ( const TiXmlNode addThis)

Add a new node related to this.

Adds a child past the LastChild. Returns a pointer to the new object or NULL if an error occured.

Definition at line 235 of file tinyxml.cpp.

References Clone(), GetDocument(), LinkEndChild(), and Type().

◆ IterateChildren() [1/2]

const TiXmlNode * TiXmlNode::IterateChildren ( const TiXmlNode previous) const

An alternate way to walk the children of a node.

One way to iterate over nodes is:

    for( child = parent->FirstChild(); child; child = child->NextSibling() )

IterateChildren does the same thing with the syntax:

    child = 0;
    while( child = parent->IterateChildren( child ) )

IterateChildren takes the previous child as input and finds the next one. If the previous child is null, it returns the first. IterateChildren will return null when done.

Definition at line 403 of file tinyxml.cpp.

References FirstChild(), and NextSibling().

◆ IterateChildren() [2/2]

const TiXmlNode * TiXmlNode::IterateChildren ( const char *  value,
const TiXmlNode previous 
) const

This flavor of IterateChildren searches for children with a particular 'value'.

Definition at line 417 of file tinyxml.cpp.

References FirstChild(), and NextSibling().

◆ LastChild() [1/2]

TiXmlNode* TiXmlNode::LastChild ( )
inline

The last child of this node. Will be null if there are no children.

Definition at line 532 of file tinyxml.h.

◆ LastChild() [2/2]

TiXmlNode* TiXmlNode::LastChild ( const char *  _value)
inline

The last child of this node matching 'value'. Will be null if there are no children.

Definition at line 535 of file tinyxml.h.

◆ LinkEndChild()

TiXmlNode * TiXmlNode::LinkEndChild ( TiXmlNode addThis)

Add a new node related to this.

Adds a child past the LastChild.

NOTE: the node to be added is passed by pointer, and will be henceforth owned (and deleted) by tinyXml. This method is efficient and avoids an extra copy, but should be used with care as it uses a different memory model than the other insert functions.
