[Zope] ZCatalog and XMLDocument problem

[Chris Gray]

This has to do with Amos's article on using XMLDocument at xml.com:
http://www.xml.com/pub/1999/12/zope/index.html

The example for finding items to catalog doesn't work for me.  When I enter
getNodeName()=='entry' in the 'expr' field I get the following error:
 Error Type: NameError
 Error Value: Eval

I'm running Debian GNU/Linux (frozen), Zope 2.1.4, Zcatalog 1.0.0 and
XMLDocument 1.0a5.

Thanks for any help you can give me on this one.
