.net操作带命名空间的xml(仅列一个获取节点值的例子其他以此类推)

公司项目需要,需要在WebServices中处理一些xml格式数据

但这些xml数据带有命名空间(xmlns)

刚开始Origami不懂,走了一些弯路,现在总结下~

附相关代码:

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Xml;
using System.IO;

namespace webservice
{
    public class verify
    {
        private string result = "";
        private XmlDocument xmlDoc;
        public string GetChinaHRXml(string inputXml)
        {
            string ATSLinkIDs = "";
            string finallyXml = "";
            LoadXML(ref xmlDoc, inputXml);
            XmlNamespaceManager namespaceManager = new XmlNamespaceManager(xmlDoc.NameTable);
            namespaceManager.AddNamespace("aa", "命名空间URL(即xmlns=后边的url)");
            XmlElement node = (XmlElement)xmlDoc.SelectSingleNode("/aa:Query/aa:QueryCondition/aa:QueryJob", namespaceManager);
            if (node != null)
            {
                ATSLinkIDs = node.InnerText;
                node = null;
            }
            xmlDoc.SelectSingleNode("/aa:Query/aa:QueryCondition/aa:QueryJob", namespaceManager).InnerText = "";
            finallyXml = xmlDoc.OuterXml;
            xmlDoc = null;
            return finallyXml;
        }
        public void LoadXML(ref XmlDocument ixmlDoc, string strXML)
        {
            ixmlDoc = new XmlDocument();
            ixmlDoc.LoadXml(strXML);
        }
    }
}

仅有一个获取值的例子,其他修改或者删除参考下边这个转载的没有操作命名空间的xml的代码

             XmlElement xesub1=xmlDoc.CreateElement("pass"); //添加person节点的里的节点
             xesub1.InnerText="123";//设置文本节点
             el.AppendChild(xesub1);
