Re: XPath Search

[Tod M. <tod...@gm...>]

Can someone help me out?  I can't seem to get the match working...

I'm using:
$components=3D$xPath->match("//component[contains(feature,'string')]");
which returns nothing in the array, even though "string" is in the file

when I use : $components=3D$xPath->match("//*[contains(.,'string')]");
however, it works.

This isn't exactly ideal though as I just want to return the component node
itself that contains the "string" within the feature, not the actual
feature.

Nigel, your solution of
$components=3D$xPath->match("//*[contains(feature,'string')]"); doesn't wor=
k
either.  It seems whenever I put the actual node name in the contains
function it doesn't work.
