Re: XPath Search

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

I've narrowed the problem down.  When I search through keywords in the xml
file (each component has one keyword tag with multiple words) it works fine
using:
$components=3D$xPath->match("//component[contains(keyword,'string')]");
but when I search through features (each component has multiple features)
using:
$components=3D$xPath->match("//component[contains(feature,'string')]");
I get an empty array.

Do I have to do something different if there are multiple tags such as
feature?
