[Zope3-checkins] CVS: zopeproducts/xml/dom/tests - test_adapters.py:1.1

[Philipp von Weitershausen]

Update of /cvs-repository/zopeproducts/xml/dom/tests
In directory cvs.zope.org:/tmp/cvs-serv28915/tests

Added Files:
	test_adapters.py 
Log Message:
The source attribute of the NodeToXMLTextAdapter is now writable. The XML
string to which it is set is parsed and used to replace to the node that is
being adapted. Added unit tests for that.


=== Added File zopeproducts/xml/dom/tests/test_adapters.py ===
