在本篇文章里小編給大家整理了關(guān)于C# 讀取XML的CDATA節(jié)點(diǎn)內(nèi)容的相關(guān)知識點(diǎn)內(nèi)容，有需要的朋友們參考學(xué)習(xí)下。

首先看實(shí)例代碼：

昨天讀取了以下XML, 之前沒有讀取過類似的格式,用一種比較笨的方法讀取的,記錄下
<?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="執(zhí)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>
    </Master>
   </RecordSet>  
  </Document>
 </ResponseContent>
</Response>
]]>
</param>
</payload>
</response>

以下是讀取xml節(jié)點(diǎn)的過程

我的目的是想要讀取CDATA里面的 <RecordSet></RecordSet> 包裹的數(shù)據(jù)

1.我先建立了一個類

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. 接著我把CDATA里面的內(nèi)容提出來

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 節(jié)點(diǎn)集合, 循環(huán)節(jié)點(diǎn)集合,賦值,以下是實(shí)現(xiàn)代碼:

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);
      }
