XmlDocument xmlDoc = new XmlDocument();            xmlDoc.Load("cmdCfg.xml");            XmlNodeList nodeList = xmlDoc.SelectSingleNode("config").ChildNodes;            if (nodeList != null)            {                foreach (XmlNode cmdNode in nodeList)                {                    XmlElement cmdElement = (XmlElement)cmdNode;                    string id = cmdElement.GetAttribute("id");                    XmlNodeList nls = cmdElement.ChildNodes;                    string showName = cmdNode.SelectSingleNode("show_name").InnerText;                    string path = cmdNode.SelectSingleNode("path").InnerText;                    string paramStr = cmdNode.SelectSingleNode("param_str").InnerText;                    XmlNode paramDetailNode = cmdNode.SelectSingleNode("param_detail[@name='param1']");                    string paramDeatilShowName = paramDetailNode.SelectSingleNode("show_name").InnerText;                }            }

xml文件：

<?xml version="1.0" encoding="utf-8" ?>
<config>
<cmd id="replace">
<show_name>字符串替换</show_name>
<path>sed</path>
<param_str>-i ‘s/${param1}/${param2}' ${param3}</param_str>
<param_detail name="param1">
<show_name>目标:</show_name>
<type>textbox</type>
<length>10</length>
</param_detail>
<param_detail name="param2">
<show_name>替换为:</show_name>
<type>textbox</type>
<length>10</length>
</param_detail>
<param_detail name="param3">
<show_name>文件路径:</show_name>
<type>file</type>
<length>50</length>
</param_detail>
<screen_out_redirect_to_file>false</screen_out_redirect_to_file>
</cmd>
