XMLType extract on XML with namespaces

Guess what, using extract('/mynode') in Oracle will not return mynode if the XML file has namespaces that Oracle doesn't recognize. The solution? use extract('/mynode','paste all your namespace declarations in here'). So for example:

extract('/mynode','xmlns="http://stupidideas.net/stupid" xmlns:dumb="http://dumb.com/dumber"')
