XPath 1.0 is a W3C standard since 1999, consider to use that. It is the 
only option available with MSXML 4, 5, 6 anyway.
Only MSXML 3 supports both XPath and XSL pattern but I don't think 
Microsoft has any documentation of that XSL pattern language which was 
implemented before XPath became a standard in 1999.

As for case-insensitive search, element and attribute names in XML are 
case sensitive, so XPath is too when it comes to element and attribute 
names. If you want to compare string values in a case insensitive manner 
then the extension function ms:string-compare
http://msdn.microsoft.com/en-us/library/ms256114.aspx
has an option to do that. It should be supported in MSXML 6:

var doc = new ActiveXObject('Msxml2.DOMDocument.6.0');
doc.loadXML('<root><foo>bar</foo><foo>BAR</foo><foo>baz</foo></root>');
doc.setProperty('SelectionLanguage', 'XPath');
doc.setProperty('SelectionNamespaces', 
'xmlns:ms="urn:schemas-microsoft-com:xslt"');
doc.selectNodes('root/foo[ms:string-compare(., "bar", "", "i") = 0]').length
