使用C＃来解析SOAP响应 [英] Using C# to parse a SOAP Response

问题描述

我想获得的faultcode值，faultstring和ORDERNUMBER从SOAP下方

 < SOAP：信封的xmlns：SOAP =htt​​p://schemas.xmlsoap.org/soap/envelope/> 
< SOAP：身体与GT; 
<&faultode的GT; 1234 LT; / faultode的> 
< faultstring> SaveOrder：SetrsOrderMain：不能更改订购日期，如果GLPeriod被关闭，新的订购日期为3/2/2010：LN：1053< / faultstring> 
<详情> 
< SOAP：信封的xmlns：SOAP =htt​​p://schemas.xmlsoap.org/soap/envelope/> 
< SOAP：身体UserGUID =测试> 
< M：SaveOrder的xmlns：M =htt​​p://www.test.com/software/schema/UserGUID =测试> 
<令ORDERNUMBER =1234-1234-123来电=OrderStatus =A的xmlns =htt​​p://www.test.com/software/schema/> 
  

下面是我在C＃

<$ P码$ p> 的XDocument DOC = XDocument.Load（HttpContext.Current.Server.MapPath（XMLexample.xml））;

变种errorDetail =新EcourierErrorDetail
{
faultode的=从FC在doc.Descendants（faultode的）
选择fc.Value，
FaultString =从c.Descendants（faultstring）FS
邻在
doc.Descendants选择fs.Value，
ORDERNUMBER =（详细信息）。元素（订单）。属性（订单号码）
选择o.Value
};
返回errorDetail;


我能够得到的数值为的faultcode和faultstring但不是订单号码。我得到枚举没有结果。任何人都可以帮忙吗？谢谢

解决方案

是的，你选择时，忽略了XML命名空间：

 < SOAP：信封的xmlns：SOAP =htt​​p://schemas.xmlsoap.org/soap/envelope/> 
 ..... 
< M：SaveOrder的xmlns：M =htt​​p://www.test.com/software/schema/UserGUID =测试> 
<令ORDERNUMBER =1234-1234-123来电=OrderStatus =A的xmlns =htt​​p://www.test.com/software/schema/> 
  

的

<排序> 标签里面在< M：; 前缀SaveOrder>，它使用了米前缀XML命名空间标记。

另外，你要选择详细信息，然后你跳到订单节点直接（使用 .Elements（） ） - 你错过了< M：SaveOrder> 之间的节点

。你需要考虑到这一点进行选择时：

 的XDocument DOC = XDocument.Load（HttpContext.Current.Server.MapPath（ XMLexample.xml））; 
 
的XNamespace的xmlns =htt​​p://www.test.com/software/schema/; 
 
 VAR orderNode = doc.Descendants号（xmlns +SaveOrder），元素符号（xmlns +订单）。 
 
 VAR值=邻在orderNode.Attributes（订单号码）
选择o.Value; 
  

这是否给你一个结果??

I am trying to get the values for faultcode, faultstring, and OrderNumber from the SOAP below

<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
    <SOAP:Body>
        <faultcode>1234</faultcode> 
        <faultstring>SaveOrder:SetrsOrderMain:Cannot change OrderDate if GLPeriod is closed, new OrderDate is 3/2/2010:Ln:1053</faultstring>               
        <detail>
           <SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
           <SOAP:Body UserGUID="test">
           <m:SaveOrder xmlns:m="http://www.test.com/software/schema/" UserGUID="test">
                <Order OrderNumber="1234-1234-123" Caller="" OrderStatus="A" xmlns="http://www.test.com/software/schema/">

Here is my code in C#

XDocument doc = XDocument.Load(HttpContext.Current.Server.MapPath("XMLexample.xml"));

var errorDetail = new EcourierErrorDetail
{
   FaultCode = from fc in doc.Descendants("faultcode")
               select fc.Value,
   FaultString = from fs in c.Descendants("faultstring")
                 select fs.Value,
   OrderNumber = from o in    
                 doc.Descendants("detail").Elements("Order").Attributes("OrderNumber")
                 select o.Value
};
return errorDetail;

I am able to get the values for both faultcode and faultstring but not the OrderNumber. I am getting "Enumeration yielded no results." Can anyone help? Thanks.

解决方案

Yes, you're ignoring the XML namespace when selecting:

<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
   .....
   <m:SaveOrder xmlns:m="http://www.test.com/software/schema/" UserGUID="test">
     <Order OrderNumber="1234-1234-123" Caller="" OrderStatus="A" xmlns="http://www.test.com/software/schema/">

The <Order> tag is inside the <m:SaveOrder> tag which uses the XML namespace prefixed by the m: prefix.

Also, you're trying to select the "detail" and then you skip to the "Order" node directly (using .Elements()) - you missed the <m:SaveOrder> node in between.

You need to take that into account when selecting:

XDocument doc = XDocument.Load(HttpContext.Current.Server.MapPath("XMLexample.xml"));

XNamespace xmlns = "http://www.test.com/software/schema/";

var orderNode = doc.Descendants(xmlns + "SaveOrder").Elements(xmlns + "Order");

var value = from o in orderNode.Attributes("OrderNumber")
            select o.Value;

Does that give you a result??
