Hello,

I'm trying to find nodes where the class name matches a regular expression, but I cannot figure out the right syntax.

I'm using HTML::TreeBuilder::XPath, and also trying to explore with the XPather Firefox extension.

The w3.org documentation mentions a matches() function, but whatever I tried has failed.

In practice, I'm looking for li nodes with class="mw-line-even" or "mw-line-odd". (yes I could just use "or", but I would like to understand how to use regexes in such a case)

Would someone know the correct syntax for something like this:

$tree->findnodes( '//li[matches(@class, "mw-line-.*")]' );

The more perlish version of what I mean could be

$tree->findnodes( '//li[ @class =~ /^mw-line-/ ]' );
