怎么用xmldocument读一个xml文件？

XmlDocument.Load 方法

[lude8880]

能给个读节点的例子吗？
比如路径是

<node1>
<node2>
value
<node2>
</node1>

[Kingsley726]

XmlDocument document = null;
try
{
document = new XmlDocument();
//path 指向你要读的文件
document.Load(path);
}catch(Exception e)
{}
finally
{}

[Kingsley726]

foreach (XmlNode node in document.SelectNodes("/node1/node2"))
{
...
}

[lude8880]

XmlDocument xd = new XmlDocument();
xd.LoadXml(eventXml);
XmlElement eventData = xd.DocumentElement;
string path = "/BuildStatusChangeEvent/Title";
XmlNode node = xd.SelectSingleNode(path);
return node.InnerText;

node怎么是null呢？下面是xml


<?xml version="1.0" encoding="utf-16"?>
<BuildStatusChangeEvent xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

load 后遍历你要的节点或属性值
