这是我试图过滤数据的内容。但我没有得到。

我想从响应中提取所有记录的列表。我不确定如何编写代码来过滤数据。

我想从这个soap响应exml中获取数据我尝试了xml节点xpath但没有工作。请帮助获取数据

【解决方案1】：

从提供的 XML 来看，它似乎分为两部分，行和字段。

字段只是行的定义。因此，您需要做的是使用每个字段的aliasnum 和name 和type 的字段创建一个类模型。例如这个：

<FIELD aliasnum="6721" control="text" filterable="+" keyfield="+" label="ctr_code" lookup="" name="ctr_code" order="1" type="VARCHAR" visible="+" width="180"/>

将转换为：

public class SoapField
{
    public string Aliasnum { get; set; }
    public string Name { get; set; }
}

这里我们只取了 Aliasnum 和 Name，它们将存储 aliasnum 和 name。这两个是我们映射行所需要的。

现在，获取name 属性列表，我们将基于它为行创建另一个类模型。

public class SoapRow
{
    public string Id { get; set; }         
    public string Code { get; set; }
    public string ContactInfoId { get; set; }
    public string ContactNote { get; set; }
    public string ContactSource { get; set; }
}

现在您需要两个循环，一个用于读取这些字段，另一个用于读取行。

我已将 XML 减少到四个字段，仅用于演示目的，您需要根据需要完成其余部分。示例：

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header/>
   <soapenv:Body>
      <MP0118_GetGridHeaderData_001_Result xmlns="http://schemas.datastream.net/MP_functions/MP0118_GetGridHeaderData_001_Result">
         <GRIDRESULT type="LIST.HEAD_DATA.STORED">
            <GRID>
               <DATA jsonclass="array">
                  <ROW id="1">
                    <D n="6721">10128</D> <!-- code -->
                    <D n="6792">11410</D> <!-- contactinfoid -->
                    <D n="6809"/>         <!-- contactnote -->
                    <D n="6774">PHON</D>  <!-- contactsource -->
                  </ROW>
               </DATA>
               <FIELDS viewtype="LIST" visibleColumn="true" visiblerowcount="">
                  <FIELD aliasnum="6721" control="text" filterable="+" keyfield="+" label="ctr_code" lookup="" name="ctr_code" order="1" type="VARCHAR" visible="+" width="180"/>
                  <FIELD aliasnum="6792" control="text" filterable="+" keyfield="-" label="ctr_contactinfoid" lookup="" name="ctr_contactinfoid" order="2" type="VARCHAR" visible="+" width="180"/>
                  <FIELD aliasnum="6809" control="text" filterable="+" keyfield="-" label="ctr_contactnote" lookup="" name="ctr_contactnote" order="3" type="MIXVARCHAR" visible="+" width="180"/>
                  <FIELD aliasnum="6774" control="text" filterable="+" keyfield="-" label="ctr_contactsource" lookup="" name="ctr_contactsource" order="4" type="VARCHAR" visible="+" width="180"/>
               </FIELDS>
            </GRID>
         </GRIDRESULT>
      </MP0118_GetGridHeaderData_001_Result>
   </soapenv:Body>
</soapenv:Envelope>

然后使用上面的类我们可以做到这一点：

var rowsList = new List<SoapRow>();
var fieldsList = new List<SoapField>(); 

//use XDocument instead of xmlDocument it's simpler and works very well with LINQ.
var doc = XDocument.Parse(xml);

// declare the namespace 
var ns = doc.Root.GetNamespaceOfPrefix("soapenv");

// get Body 
var body = doc.Descendants(ns + "Body").Elements();

// get MP0118_GetGridHeaderData_001_Result
var gridresultheader = body.ElementAt(0).Elements();

// get GRIDRESULT
var gridresult = gridresultheader.ElementAt(0).Elements();

// get GRID
var grid = gridresult.ElementAt(0).Elements();

// get DATA
var rows = grid.ElementAt(0).Elements();

// get FIELDS
var fields = grid.ElementAt(1).Elements();

// define the fields first
foreach(var field in fields)
{
    fieldsList.Add(
        new SoapField()
        {
            Aliasnum = field.Attribute("aliasnum").Value.Trim(), 
            Name = field.Attribute("name").Value.Substring(4).Trim() //get the name without (ctr_)
        }
        );
}

// now loop over the rows, and map them to the fields.
foreach (var row in rows)
{
    // get the row id
    var id = row.Attribute("id").Value.Trim();

    //get the row elements
    var d = row.Elements();

    //set the row id first
    var dataRow = new SoapRow
    {
        Id = id
    };

    // go over each element in the row
    foreach (var element in d)
    {
        // get the row n attribute
        var n = element.Attribute("n").Value.Trim();

        // get the name of this element by the n attribute from the fields definition.
        var name = fieldsList.Where(e => e.Aliasnum == n).Select(x => x.Name).First();

        // now just map it using a simple switch statment.
        switch(name)
        {
            case "code":
                dataRow.Code = element.Value.Trim();
                break;
            case "contactinfoid":
                dataRow.ContactInfoId = element.Value.Trim();
                break;
            case "contactnote":
                dataRow.ContactNote = element.Value.Trim();
                break;
            case "contactsource":
                dataRow.ContactSource = element.Value.Trim();
                break;
        }

    }

    // add the row results into the list 
    rowsList.Add(dataRow);

}

结果将在rowsList 中。

代码可以进一步简化，但我想尽可能清楚地显示每个步骤。

衷心感谢您的回复。我会试试这个让你知道

【解决方案2】：

有一个网站https://xmltocsharp.azurewebsites.net/ 可以提取到c# 也许它会帮助你

我需要如何过滤数据
using (WebResponse response = httpWebRequest.GetResponse()) { using (StreamReader streamreader = new StreamReader(response.GetResponseStream())) { string result1 = streamreader.ReadToEnd(); MessageBox.Show(result1); xmlDocument = 新的 XmlDocument(); xmlDocument.LoadXml(result1);
用于过滤响应中的数据
foreach (XmlElement xmlElement in xmlDocument.DocumentElement.SelectNodes("//DATA/ROW[*]/D[text()]")) { Console.WriteLine(xmlElement.OuterXml);字符串结果2 = streamreader.ReadToEnd(); }
