如何获取xml中某个指定节点的值

Answer 1

// <summary>
/// 读取xml中的指定节点的值
/// </summary>
private string ReadXmlNode(string filename)
{
string result = "-1";
XmlDocument xmlDoc = new XmlDocument();
try
{
xmlDoc.LoadXml(filename);
//读取Activity节点下的数据。SelectSingleNode匹配第一个Activity节点
XmlNode root = xmlDoc.SelectSingleNode("//head");//当节点Workflow带有属性是，使用SelectSingleNode无法读取
if (root != null)
result = (root.SelectSingleNode("code")).InnerText;

}
catch //(Exception e)
