</database>

<sqlMaps>
<sqlMap embedded= "Map.SqlClient.BUAction.xml,Crm "/>

要求找到 properties 节点.并把url的值改成 "E:\CRM "


[解决办法]
Xmldocument doc = new Xmldocument();
doc.Load(@ "e:\1.xml ");

XmlElement node = (XmlElement)doc.SelectSingleNode( "//properties ");
node.SetAttribute( "url ", @ "E:\CRM ");

doc.Save(@ "e:\1.xml ");
[解决办法]
参考 创建、查询、修改带名称空间的 XML 文件的例子
http://dotnet.aspx.cc/article/7b4c7a42-4cdf-40d1-b293-e86da109a34c/read.aspx

找到属性节点都设置即可

XmlNode xx = doc.SelectSingleNode( "//xxx名称空间:properties/@url ",nsmanager)
xx.value= "E:\\CRM "

[解决办法]
硬编码

doc.ChildNodes[1].FirstChild.SetAttribute( "url ", @ "E:\CRM ");
