怎么将XML字符串转换为XmlDocument，并获取部分节点值

我们的目标：解析XML字符串，并获取节点：z:row下的属性：ows_LinkFilename的值集合？？？

XML字符串数据结构如下：

<listitems xmlns:s='uuid:BDC6E3F0-6DA3-11d1-A2A3-00AA00C14882' xmlns:dt='uuid:C2F41010-65B3-11d1-A29F-00AA00C14882' xmlns:rs='urn:schemas-microsoft-com:rowset' xmlns:z='#RowsetSchema' xmlns='http://schemas.microsoft.com/sharepoint/soap/'>

            Console.ReadLine();

结果图如下：

总结关键知识点：

1-如何将XML字符串转换为XmlDocdument：

　　XmlDocument xmlDocument = new XmlDocument();

　　xmlDocument.LoadXml(xmlStr);

2-获取XmlDoment下的节点：

　　xmlDocument.GetElementsByTagName("rs:data")

3-获取XmlNode下的属性值：

　　node.Attributes["ows_LinkFilename"].Value
