C# 读取XML的CDATA节点内容.

昨天读取了以下XML, 之前没有读取过类似的格式,用一种比较笨的方法读取的,记录下<?xml version="1.0"?>
<response>
<srvver>1.0</srvver>
<srvcode>000</srvcode>
<payload>
<param type="XML" key="data">
<![CDATA[
<Response>
  <Execution>
    <Status code="0" sql_code="0" description="执行成功！"/>
  </Execution>
  <ResponseContent>
    <Parameter/>
    <Document>
      <RecordSet id="1">
        <Master name="M" node_id="1">
          <Record>
            <Field name="MTRL_ID" value="51722500H031"/>
            <Field name="IS_MAIN" value="Y"/>
            <Field name="MAIN_ID" value="51722500H031"/>
            <Field name="DOSAGE" value="1.0"/>
            <Field name="NN_QTY" value="1000.0"/>
            <Field name="TN_QTY" value="1000.0"/>
            <Field name="SEQ" value="70.0"/>
            <Field name="POINT_STR" value=""/>
          </Record>
        </Master>
      </RecordSet>
      <RecordSet id="2">
        <Master name="M" node_id="2">
          <Record>
            <Field name="MTRL_ID" value="51820590H001"/>
            <Field name="IS_MAIN" value="N"/>
            <Field name="MAIN_ID" value="51820590H001"/>
            <Field name="DOSAGE" value="1.0"/>
            <Field name="NN_QTY" value="1000.0"/>
            <Field name="TN_QTY" value="500.0"/>
            <Field name="SEQ" value="30.0"/>
            <Field name="POINT_STR" value=""/>
          </Record>
        </Master>
      </RecordSet>
      <RecordSet id="3">
        <Master name="M" node_id="3">
          <Record>
            <Field name="MTRL_ID" value="51820710H002"/>
            <Field name="IS_MAIN" value="N"/>
            <Field name="MAIN_ID" value="51820510H002"/>
            <Field name="DOSAGE" value="0.0"/>
            <Field name="NN_QTY" value="0.0"/>
            <Field name="TN_QTY" value="1000.0"/>
            <Field name="SEQ" value="20.0"/>
            <Field name="POINT_STR" value=""/>
          </Record>

      </RecordSet>

  </ResponseContent>
</Response>
]]>
</param>
</payload>
</response>

以下是读取xml节点的过程

我的目的是想要读取CDATA里面的 <RecordSet></RecordSet> 包裹的数据

1.我先建立了一个类

 public class ReadXml
    {
        public string RecordSet;
        public string MTRL_ID;
        public string IS_MAIN;
        public string MAIN_ID;
        public string DOSAGE;
        public string NN_QTY;
        public string TN_QTY;
        public string SEQ;
        public string POINT_STR;
    }

2. 接着我把CDATA里面的内容提出来

XmlDocument doc = new XmlDocument();
            doc.LoadXml(strFile); var cdata = (XmlCDataSection)doc.SelectSingleNode("/response/payload/param/text()");

3. 然后用XElement的Linq方法找到 RecordSet 节点集合, 循环节点集合,赋值,以下是实现代码:

 XElement xe = XElement.Parse(cdata.InnerText);
 IEnumerable<XElement> elements = from ele in xe.Elements("ResponseContent").Elements("Document").Elements("RecordSet") select ele;
            List<ReadXml>  xmlNodeList = new List<ReadXml>();
            foreach (var ele in elements)
            {
                ReadXml xmlNode= new ReadXml();
                model.RecordSet = ele.Attribute("id").Value;

               var subeles = ele.Elements("Master").Elements("Record").Elements("Field");
                foreach (var item in subeles)
                {
                    if (item.Attribute("name").Value == "MTRL_ID")
                    {
                        xmlNode.MTRL_ID = item.Attribute("name").NextAttribute.Value;
                    }
                    if (item.Attribute("name").Value == "IS_MAIN")
                    {
                        xmlNode.IS_MAIN = item.Attribute("name").NextAttribute.Value;
                    }
                    if (item.Attribute("name").Value == "MAIN_ID")
                    {
                        xmlNode.MAIN_ID = item.Attribute("name").NextAttribute.Value;
                    }
                    if (item.Attribute("name").Value == "DOSAGE")
                    {
                        xmlNode.DOSAGE = item.Attribute("name").NextAttribute.Value;
                    }
                    if (item.Attribute("name").Value == "NN_QTY")
                    {
                        xmlNode.NN_QTY = item.Attribute("name").NextAttribute.Value;
                    }
                    if (item.Attribute("name").Value == "TN_QTY")
                    {
                        xmlNode.TN_QTY = item.Attribute("name").NextAttribute.Value;
                    }
                    if (item.Attribute("name").Value == "SEQ")
                    {
                        xmlNode.SEQ = item.Attribute("name").NextAttribute.Value;
                    }
                    if (item.Attribute("name").Value == "POINT_STR")
                    {
                        xmlNode.POINT_STR=item.Attribute("name").NextAttribute.Value;
                    }
                }
                xmlNodeList.Add(xmlNode);
            }

可以, 应该有更好的方法去读取, 这里是用比较笨的方法去实现了这个xml的读取.
