C# 操作xml <![CDATA[ ]]>................................新手求解,在线等

Question

<?xml version="1.0" encoding="utf-8"?>
<root>
  <left>
  </left>
  <center>
    <div1>
<![CDATA[ <div id="div1"><div> ]]>
    </div1>
  </center>
  <right>
  </right>
</root>通过C# 
先新建div1节点，然后在div1节点写入<![CDATA[ <div id="div1"><div> ]]>public static void XmlInsertHtmlCode(string xmlPath, string MainNode, string Element, string Content)
        {
            XmlDocument objXmlDoc = new XmlDocument();
            objXmlDoc.Load(xmlPath);
            XmlNode objNode = objXmlDoc.SelectSingleNode(MainNode);
            XmlElement objElement = objXmlDoc.CreateElement(Element);
            objElement.InnerXml = Content;
            objNode.AppendChild(objElement);
            objXmlDoc.Save(xmlPath);
        }1.调用：XmlInsertHtmlCode("xxx.xml","root/center","div1","<div id="div1"><div>");
  我的为什么不行  使用innerxml 得到的结果是<div1><div id="div1"><div></div1>
  而不是 <div1><![CDATA[ <div id="div1"><div> ]]></div1>
2.我该怎么取出 <div1><![CDATA[ <div id="div1"><div> ]]></div1> 中的<div id="div1"><div>两个问题求解,给源码。谢谢~

Answer 1

net 2.0的XmlDocument不支持，只能用InnerText取得
            string temp2 = @"<?xml version=""1.0"" encoding=""utf-8""?>
<root>
  <left>
  </left>
  <center>
    <div1>
        <![CDATA[ <div id=""div1""><div> ]]>
    </div1>
  </center>
  <right>
  </right>
</root>";            XmlDocument doc = new XmlDocument();
            doc.LoadXml(temp2);            XmlNode node2 = doc.SelectSingleNode("/root/center/div1");
            string comment = node2.FirstChild.InnerText;

Answer 2

写入用InnerText:
            string temp2 = @"<?xml version=""1.0"" encoding=""utf-8""?>
<root>
  <left>
  </left>
  <center>
    <div1>
        <![CDATA[ <div id=""div1""><div> ]]>
    </div1>
  </center>
  <right>
  </right>
</root>";            XmlDocument doc = new XmlDocument();
            doc.LoadXml(temp2);            XmlNode node2 = doc.SelectSingleNode("/root/center/div1");
            string comment = node2.FirstChild.InnerText;            node2.FirstChild.InnerText = @"<div id=""div2""><div>";

Answer 3

net 3.5的LinqToXml有XCData 类型
            string temp2 = @"<?xml version=""1.0"" encoding=""utf-8""?>
<root>
  <left>
  </left>
  <center>
    <div1>
        <![CDATA[ <div id=""div1""><div> ]]>
    </div1>
  </center>
  <right>
  </right>
</root>";            XDocument doc2 = XDocument.Parse(temp2);
            XElement elment =doc2.Element("root").Element("center").Element("div1");
            XCData comment2 = elment.DescendantNodes().ToList()[0] as XCData;
            comment2.Value = @"<div id=""div2""><div>";

Answer 4

楼2、3 使用code  结果是
<div1>&lt;dl class="baseball" id="div1"&gt;</div1>

Answer 5

public static void XmlInsertHtmlCode(string xmlPath, string MainNode, string Element, string Content)
        {
            XmlDocument objXmlDoc = new XmlDocument();
            objXmlDoc.Load(xmlPath);
            XmlNode objNode = objXmlDoc.SelectSingleNode(MainNode);
            XmlElement objElement = objXmlDoc.CreateElement(Element);
            objElement.InnerXml = Content;
            objNode.AppendChild(objElement);
            objXmlDoc.Save(xmlPath);
        }
调用 XmlInsertHtmlCode("xxx.xml","root/center","div1","<div id="div1"><div>");
创建节点div1，div1的值为<div id="div1"><div>，我想储存为
<div1><![CDATA[ <div id="div1"><div> ]]></div1>
但是现在是
<div1>&lt;dl class="baseball" id="div1"&gt;</div1>问题1.我要怎么修改XmlInsertHtmlCode这个方法才能实现？
问题2.我想取出div1节点的值<div id="div1"><div>，又该怎么实现？

Answer 6

有写入app.config的吗？（winform的）

Answer 8

感谢8楼的方法。
贴出xml的两个方法
        /// <summary>
        /// 取出节点值
        /// </summary>
        /// <param name="xmlPath">xml url</param>
        /// <param name="Node">root/test</param>
        /// <returns></returns>
        public static string[] XmlGetHtmlCode(string xmlPath,string Node)
        {
            XmlDocument objXmlDoc = new XmlDocument();
            objXmlDoc.Load(xmlPath);            XmlNodeList elemList = objXmlDoc.GetElementsByTagName(Node);
            string[] arraw = new string[elemList.Count];
            for (int i = 0; i < elemList.Count; i++)
            {
                arraw[i] = elemList[i].InnerXml.ToString().Replace("<![CDATA[", "").Replace("]]>", ""); ;
            }            return arraw;
        }/// <summary>
        /// 插入一节点不带属性,节点值为<![CDATA[
        /// </summary>
        /// <param name="xmlPath">xml url</param>
        /// <param name="MainNode">root/test</param>
        /// <param name="Element">text1</param>
        /// <param name="Content">节点内容</param>
        public static void XmlInsertHtmlCode(string xmlPath, string MainNode, string Element, string Content)
        {
            XmlDocument objXmlDoc = new XmlDocument();
            objXmlDoc.Load(xmlPath);
            XmlNode objNode = objXmlDoc.SelectSingleNode(MainNode);
            XmlElement objElement = objXmlDoc.CreateElement(Element);
            XmlCDataSection CData;
            CData = objXmlDoc.CreateCDataSection(Content);
            objElement.AppendChild(CData);
            objNode.AppendChild(objElement);
            objXmlDoc.Save(xmlPath);
        }

XmlInsertHtmlCode（"xxx.xml","节点名称"）
