Is this XHTML document valid for parsing with the iPhone
I would be grateful if someone could clarify if this document is valid for xhtml parsing using the iphone SDK using xpaths:

I'm trying to extract the currently playing player-track 'lush' and player-artist 'ladykillers' through using xpath. If I do an xpath search for: //@class and then print the result to screen, I get player-track, player-artist.. etc outputted?
Am I missing something fairly obvious here?
Thanks
Dan
The W3C Markup Validation Service comes up with 9 errors in this document.
So, this is not a valid XHTML document, for iPhone usage or otherwise.
Your XPath result is giving you what you're asking for which is the values of the class attributes.
To get the currently playing player-track use:
//*[@id = 'player-currently-playing']/*[@class = 'player-track']/text()
and to get the currently playing player-artist use:
//*[@id = 'player-currently-playing']/*[@class = 'player-artist']/text()
加载中,请稍侯......
