Question

I am developer of Windows phone 7, and I want to ask: if I go to .xml code, and there is such

<?xml version="1.0" encoding="utf-8"?>

<artists>
<images>
<image size="1">http://userserve-ak.last.fm/serve/34/17666215.jpg</image>
<image size="2">http://userserve-ak.last.fm/serve/64/17666215.jpg</image>
</images>
</artists>

因此,我如何选择其中的第二个要素?

我的理解是,你想要把这部XML文件整理起来,并取得第二点价值,因此,你可以这样做:

XDocument xmlDocument = XDocument.Parse("path_to_xml_file");
//you can also pass a the content as a string or a stream reader

XElement image = (from element in xmlDocument.Element("artists").Element("images").Descendants("image")
                          where element.Attribute("size").Value == "2"
                          select element).FirstOrDefault();

System.Diagnostics.Debug.WriteLine(image.Value);

之后加上这一进口:

using System.Linq;
using System.Xml.Linq;

此外,还提到了该系统。页: 1
