Enhance minidom in order to have ordered (instead of sorted) attributes, and a 'getElementsByAttributeName' method

Project description

This module enhances minidom and will allow you to have ordered attributes instead of having them sorted automaticaly.

It is relevent in the fact that you may want to script the loading/modification/saving of xml files and then print out a diff. with the normal minidom since attributes are sorted automaticaly you can have an unwanted diff for each unchaged line just because the order of the attributes changed.

once you load this module, just use minidom normaly.

example:

>>> from xml.dom import minidom
>>> import enhancedminidom

then use minidom normaly except that:

  • Document and Element classes have a ‘getElementsByAttributeName’ method which can be verry handy.
  • ‘toxml’ and ‘toprettyxml’ will print attributes in the order they are created/loaded if ‘minidom.SORTEDATTRIBUTES = False’ (default)

example to get all nodes having a “foo” attribute:

>>> document = minidom.parse('yourfile.xml')
>>> nodes_with_foo = document.getElementsByAttributeName('foo')

example to get all nodes having a “foo” attribute if they are in a “fum” tag:

>>> document = minidom.parse('yourfile.xml')
>>> nodes_with_foo = document.getElementsByAttributeName('foo', 'fum')
