Re^2: XML::LibXML::XPathContext findnodes() Question

[AbrahamB]

I'm trying to test the existence of two separate elements.
Like /root && /root/element1. I want true if both exist, false if one exists.

The xpath can certainly be much better, but this is a simplified example from an xml-grep program I am working on.
I'm trying to add the functionality to test for the existence of 2 nodes separated by ' and '. I may need to use find() or findvalue() for these types of xpaths.

Thanks for your time!

If /root/element1 exists, then /root certainly exists.

You should probably use $doc->findvalue instead of findnodes because your XPath expression doesn't return a nodeset but boolean value.

warn $doc->findvalue('/root and /root/element1'), "\n";
warn $doc->findvalue('/root and /root/nosuch'), "\n";

yields:

true
false
