TiXmlVisitor¶

from panda3d.core import TiXmlVisitor

class TiXmlVisitor¶

Implements the interface to the “Visitor pattern” (see the Accept() method.) If you call the Accept() method, it requires being passed a TiXmlVisitor class to handle callbacks. For nodes that contain other nodes (Document, Element) you will get called with a VisitEnter/VisitExit pair. Nodes that are always leaves are simply called with Visit().

If you return ‘true’ from a Visit method, recursive parsing will continue. If you return false, no children of this node or its sibilings will be Visited.

All flavors of Visit methods have a default implementation that returns ‘true’ (continue visiting). You need to only override methods that are interesting to you.

Generally Accept() is called on the TiXmlDocument, although all nodes suppert Visiting.

You should never change the document from a callback.
