Problem with XPath query

Given the following XML:









I'm using the following query:

$oXPath->query( '//DisplayRef/parameter[@alias="widgetType and
@value="system"]' );

and I'm getting the following error:

Warning: DOMXPath::query() [function.DOMXPath-query]: Invalid predicate

If I remove this part of the query

[@alias="widgetType and @value="system"]

the error goes away.

As far as I can tell from googling around, the query is valid. If
that's the case, I don't understand what's causing the error.
Could someone explain to me what I'm doing wrong?

thnx,
Christoph

Re: Problem with XPath query

Hi,

You are missing a quote after widgetType:

[@alias=3D"widgetType and @value=3D"system"]

should be

[@alias=3D"widgetType" and @value=3D"system"]

Regards,

Jonathan

Yeah, I realized that about 2 minutes after I sent the message. Man,
I'm dumb. :p I was banging my head against the wall for a while
because of that. I guess when you bring your stupidity public, you'll
find the solution yourself that much quicker. ;)

I often find that it's quicker to ask - because invariably the answer presents
itself the second you hit send ;)
