如何从上面文件获得想要元素
比如
price为19.95的author

[yagebu1983]

/// <summary>
/// 读取指定节点的值(InnerText)
/// </summary>
/// <param name="strNode">节点名称</param>
/// <returns></returns>
public string GetXmlNodeValue(string strNode)
{
string strReturn = String.Empty;
try
{
XmlNode xmlNode = xmlDoc.SelectSingleNode(strNode);
if (xmlNode != null)
{
strReturn = xmlNode.InnerXml;
}
}
catch (XmlException xmle)
{
throw xmle;
}
return strReturn;
}

mark先

XPATH也不能解决吗。
/bookstore/book[Price="19.95"]
这样至少能找到price为19.95的全部book出来
再想取得author不就水到渠成了

[ericzhangbo1982111]

xmlpath就可以阿/bookstore/book[price='19.95'/author]

[ericzhangbo1982111]

/bookstore/book[price='19.95']/author] 少了一括号

[shenpengbird]

xmlpath拼路径 楼上说的很详细了
