                                    PyXBSAXHandler

A SAX handler class which generates a binding instance for a document through a streaming parser.

An example of using this to parse the document held in the (unicode) text value xmlt is:

 import pyxb.binding.saxer
 import io

 saxer = pyxb.binding.saxer.make_parser()
 handler = saxer.getContentHandler()
 saxer.parse(io.StringIO(xmlt))
 instance = handler.rootObject()

rootObject(self)

source code

Return the binding object corresponding to the top-most element in the document

Returns:

An instance of basis._TypeBinding_mixin (most usually a basis.complexTypeDefinition.

Raises:

pyxb.[UnrecognizedDOMRootNodeError - No binding could be found to match the top-level element in the document.

Overrides: utils.saxutils.BaseSAXHandler.rootObject

reset(self)

source code

Reset the state of the handler in preparation for processing a new document.

Returns:: self
Overrides: utils.saxutils.BaseSAXHandler.reset

init(self, **kw)
(Constructor)

source code

source code

Process the start of an element.

Overrides: xml.sax.handler.ContentHandler.startElementNS: (inherited documentation)
