XML::XPath Question

[Konstantinos Agouros]

Hi,

I would like to do a relative search on a subtree.

Say I got a NodeCollection doing something like:

$list = $xmlpath->find("/a/b")

Now I iterate about all instances of <b> in the document and for each one
I want to find the c's that have attribute foo.

so I do a foreach my $bar ($list->get_nodelist)
{
...
}

can I do a $bar->find("c[@foo]") or how can I do this relative to the
subtree of each b?

Regards,

Konstantin

You want

my $clist = $xmlpath->find('./c[@foo]', $bar);

or './/c[@foo]' if you want indirect as well as direct descendents.
