However, seeing 'namespaces' and 'never returns anything' makes me think you're having issues with the default namespace concept. While XML documents have a default namespace, XPaths do not. Once you use namespaces in an xml document, all your xpaths will need to use namespace declarations for all the path parts, even for tags that are defaulted in the document. So, you'll need to declare a namespace prefix that matches the default namespace in the doc. Give us a small example that you've tried that doesn't work, we'll fix it.

Normally this seems to work fine, but with namespace declarations this seems especially problematic as nothing ever returns and nothing errors. Would it be possible to confirm what correct functions and order of operations would be for this? Even if the example is C, I can translate that to Python. </blockquote><blockquote type="cite"> </blockquote> -- Ross Reedstrom, Ph.D. <a href="mailto:reedstrm@rice.edu">reedstrm@rice.edu</a> Systems Engineer & Admin, Research Scientist phone: 713-348-6166 Connexions <a href="http://cnx.org">http://cnx.org</a> fax: 713-348-3665 Rice University MS-375, Houston, TX 77005 GPG Key fingerprint = F023 82C8 9B0E 2CC6 0D8E F888 D3AE 810E 88F0 BEDE ------------------------------ Subject: Digest Footer _______________________________________________ xml mailing list <a href="mailto:xml@gnome.org">xml@gnome.org</a> <a href="https://mail.gnome.org/mailman/listinfo/xml">https://mail.gnome.org/mailman/listinfo/xml</a> ------------------------------ End of xml Digest, Vol 128, Issue 2 *********************************** </div></blockquote></body></html>
