Method Details

__init__(self)
(Constructor)

Overrides:
_xmlplus.sax.handler.ContentHandler.__init__

_object_created_(self, obj)

characters(self, content)

Called by the internal SAX parser whenever text (not part of a tag) is encountered.
Overrides:
_xmlplus.sax.handler.ContentHandler.characters

comment(self, text)

endCDATA(self)

endDTD(self)

endElementNS(self, name, qname)

Called by the internal SAX parser whenever an ending XML tag/element is encountered.
Overrides:
_xmlplus.sax.handler.ContentHandler.endElementNS

endEntity(self, name)

finalValidation(self)

Perform a final validation of the tags. Checks if all required tags are really defined (via tag-counter dictionary).

getRoot(self)

Returns:
the root node of the object tree

getRootComments(self)

Returns:
sequence of comment tags given before the root node

initValidation(self)

Update some statistics about the elements in use. All 'required' elements will be added to the sequence _requiredTags and all elements having a True value set for 'SingleInstance' will be added to the sequence _singleInstanceTags. Additionally the tag-counter dictionary will be reset.

startCDATA(self)

startDTD(self, name, public_id, system_id)

startElementNS(self, name, qname, attrs)

Signals the start of an element in namespace mode.

The name parameter contains the name of the element type as a (uri, localname) tuple, the qname parameter the raw XML 1.0 name used in the source document, and the attrs parameter holds an instance of the Attributes class containing the attributes of the element.

The uri part of the name tuple is None for elements which have no namespace.
Overrides:
_xmlplus.sax.handler.ContentHandler.startElementNS

startEntity(self, name)
