Methods
- __init__(self, reader=None)
- evaluateExpression(self, context, expression)
- execute(self, node, xupdate, variables=None, processorNss=None)
- output(self)
-
Returns the current output writer
- parseAVT(self, avt)
- popResult(self)
- pushDomResult(self, ownerDocument)
- pushStringResult(self)
- visit(self, context, node, preserveSpace)
- class Reader(Ft.Xml.Domlette.NonvalidatingReaderBase)
-

It does not need to detect XUpdate syntax errors.
Methods
- fromSrc = parse(self, inputSource)
-
Reads XML from an Ft.Xml.Inputsource.InputSource, and
returns a Domlette document node.

Functions
- ApplyXUpdate(doc, xup)

Takes 2 InputSources, one for the source document and one for the
XUpdate instructions. It returns a DOM node representing the result
of applying the XUpdate to the source document (the document is
modified in-place).
