Save xml node to string c#

[p30suite]

I have and XML like this:\[code\]<album> <image size="small">http://exaplem/example.jpg</image> <image size="medium">http://exaplem/example.jpg</image> <image size="large"> http://userserve-ak.last.fm/serve/174s/42566323.png </image> <image size="extralarge"> http://exaplem/example.jpg </image></album>\[/code\]...and I want to extract and save \[code\]<image size="large">...</image>\[/code\] as string.My goal is obtaining the child text node of the extracted element. For example \[code\]http://userserve-ak.last.fm/serve/174s/42566323.png\[/code\].I've tried with\[code\]XmlNodeList xnList = xml.SelectNodes("image[@size='large']"); foreach (XmlNode xn in xnList) { ..... }\[/code\]... but I'm someway lost.What's the best way to do what I require to do?
