behavior.
Added support for the Attr.ownerElement attribute.
Everywhere: Define constant object attributes in the classes rather than
on the instances during object construction. This reduces the amount of
work needed for object construction and destruction; these need to be
lightweight operations on a DOM.
Node._get_firstChild(),
Node._get_lastChild(): Return None if there are no children (required for
compliance with DOM level 1).
Node.insertBefore(): If refChild is None, append the new node instead of
failing (required for compliance). Also, update the sibling
relationships. Return the inserted node (required for compliance).
Node.appendChild(): Update the parent of the appended node.
Node.replaceChild(): Actually replace the old child! Update the parent
and sibling relationships of both the old and new children. Return
the replaced child (required for compliance).
Node.normalize(): Implemented the normalize() method. Required for
compliance, but missing from the release. Useful for joining
adjacent Text nodes into a single node for easier processing.
Node.cloneNode(): Actually make this work. Don't let the new node share
the instance __dict__ with the original. Do proper recursion if
doing a "deep" clone. Move the attribute cloning out of the base
class, since only Element is supposed to have attributes.
Node.unlink(): Simplify handling of child nodes for efficiency, and
remove the attribute handling since only Element nodes support
attributes.
Attr.cloneNode(): Extend this to clear the ownerElement attribute in
the clone.
AttributeList.items(),
AttributeList.itemsNS(): Slight performance improvement (avoid lambda).
Element.cloneNode(): Extend Node.cloneNode() with support for the
attributes. Clone the Attr objects after creating the underlying
clone.
Element.unlink(): Clean out the attributes here instead of in the base
class, since this is the only class that will have them.
Element.toxml(): Adjust to create only one AttributeList instance; minor
efficiency improvement.
_nssplit(): No need to re-import string.
Document.__init__(): No longer needed once constant attributes are
initialized in the class itself.
Document.createElementNS(),
Document.createAttributeNS(): Use the defined constructors rather than
directly access the classes.
_get_StringIO(): New function. Create an output StringIO using the most
efficient available flavor.
parse(),
parseString(): Import pulldom here instead of in the public namespace of
the module.
correct order of constructor args in createAttributeNS
pulldom: use symbolic names for uri and localnames
correct usage of createAttribute and setAttributeNode signatures.
callers of feed will get a SAXException.
In close, feed the last chunk first before calling endDocument, so that
the parser may report errors before the end of the document. Don't do
anything in a nested parser.
Don't call endDocument in parse; that will be called in close.
Use self._source for finding the SystemID; XML_GetBase will be cleared in
case of an error.
caused the drive letter to cause urlopen() to think it was an unrecognized
URL scheme. This only passes system ids to urlopen() if the file does not
exist. It works on Windows & Unix.
It should work everywhere else as well.
xml.sax: Fix parse and parseString not to rely on ExpatParser
Greatly simplify import logic by using __import__
saxutils: Support Unicode strings and files as parameters to
prepare_input_source
Add support for parsing already-opened files. Make sure the parse()
method closes exactly those files that it opens.
Modified by FLD for better conformance to the Python style guide.
This closes SourceForge patch #101512.
