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.
enum TiXmlNode::NodeType |
The types of XML nodes supported by TinyXml.
(All the unsupported types are picked up by UNKNOWN.)
|
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().

pure virtual |
Create an exact duplicate of this node and return it.
The memory must be deleted by the caller.
Implemented in TiXmlDocument, TiXmlUnknown, TiXmlDeclaration, TiXmlText, TiXmlComment, and TiXmlElement.
Referenced by InsertAfterChild(), InsertBeforeChild(), InsertEndChild(), marlin::XMLParser::parse(), marlin::XMLParser::processconditions(), and ReplaceChild().
const TiXmlNode * TiXmlNode::FirstChild | ( | const char * | value | ) | const |
The first child of this node with the matching 'value'.
Will be null if none found.
References Value().
const TiXmlDocument * TiXmlNode::GetDocument | ( | ) | const |
Return a pointer to the Document this node lives in.
Returns null if not in a document.
References ToDocument().
Referenced by InsertAfterChild(), InsertBeforeChild(), InsertEndChild(), LinkEndChild(), and TiXmlElement::SetAttribute().
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.

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.

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.
References Clone(), GetDocument(), LinkEndChild(), and Type().
Referenced by marlin::XMLFixCollTypes::parse(), and marlin::XMLParser::parse().
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.

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.

friend |
An output stream operator, for every class.
Note that this outputs without any newlines or formatting, as opposed to Print(), which includes tabs and new lines.
The operator<< and operator>> are not completely symmetric. Writing a node to a stream is very well defined. You'll get a nice stream of output, without any extra whitespace or newlines.
But reading is not as well defined. (As it always is.) If you create a TiXmlElement (for example) and read that from an input stream, the text needs to define an element or junk will result. This is true of all input streams, but it's worth keeping in mind.
A TiXmlDocument will read nodes until it reads a root element, and all the children of that root element.

friend |
An input stream operator, for every class.
Tolerant of newlines and formatting, but doesn't expect them.
