That sounds more like you are not using XPath in IE, make sure you are 
using IE 6 or you use IE 5/5.5 with MSXML 3 or later and you call
   xmlDocument.setProperty('SelectionLanguage', 'XPath')
before you use selectNodes/selectSingleNode as otherwise you are not 
using XPath 1.0 but some other selection language that MS implemented 
before they implemented the W3C recommendation XPath 1.0.
And of course with MSXML if you want to use prefixes in XPath expression 
you have to declare them e.g.
   xmlDocument.setProperty('SelectionNamespaces', 
'xmlns:pf1="http://example.com/ns1" xmlns:pf2="http://example.org/ns"');

Sure
   //*
for instance or
   //@*
will work but of course if you want to match elements in a namespace 
then you need to use prefixes or inefficient workarounds like
   //*[local-name() = 'Mastercolumn']
