[phpXML] RE: [phpXML] Re: [phpXML] Problems using element[@attribute=''] syntax ??

Nigel,

Many thanks for that, it works a treat. Also interesting that once I'd done
that I got an error from phpXML that normalize-space() isn't supported by
the parser yet! But no worries, I removed that and it worked fine.

Thanks again - you're right the documentation isn't clear on this point but
now I know it, I'll not have the problem again!

Regards,

Gareth
