Using XQuery to search for Node having specific details

[daryo]

I'm not an expert in XQuery and I'm having to search though big collection of files,the XML doc have a structure like this,\[code\]<files><file> <name>1</name> <contents> <content>games</content> <content>movies</content> </contents></file><file> <name>2</name> <contents> <content>games</content> <content>picture</content> <content>work</content> </contents></file>\[/code\]its like the user i have a set of content like may be ("games","movies") and I have to return the nameso far i wrote only this\[code\]for $x in /files/file return $x/content\[/code\]I want to know whether this is possible with XQuery? if possible, just give me some guidelines, i'm not aware of all xquery constructs, thats my main drawback
