I wouldn't be using XML for parsing webpages to fetch a word like that, as if theres an XML parse error the script fails to solve your problem.

Personally I would use the string functions or regular expressions to match the markup where the data I would like to fetch exists. I've done this quite a few times when I needed to fetch online status on variously skinned forums to get my online status and such.

But in the end it depends on what you want to grab ;)
