removing/extracting soap header and body from soap message
提问by batmaci
I have a soap message shown below. I would like to get only request element and its child nodes.
我有如下所示的肥皂消息。我只想获取请求元素及其子节点。
<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope"
xmlns:xlink="http://www.w3.org/1999/xlink"
xmlns:ds="http://www.w3.org/2000/09/xmldsig#"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://location.xsd">
<soap:Header xmlns="http://www.server.net/schema/request.xsd">
</soap:Header>
<soap:Body>
<Request ReqRespVersion="large" Version="1" EchoToken="1.0" xmlns="http://mynamespace.com">
.....
</Request>
</soap:Body>
</soap:Envelope>
I am able to get it using this code.
我可以使用此代码获取它。
Dim myXDocument As XDocument = XDocument.Load(New StringReader(Request))
Dim Xns As XNamespace = XNamespace.Get("http://mynamespace.com")
SoapBody = myXDocument.Descendants(Xns + "Request").First().ToString
But I dont want to use specific name like "Request" because I have more than soap messages and each have different xml element name. so I need a general function instead of making a specific function for each.
但我不想使用像“请求”这样的特定名称，因为我有更多的肥皂消息，而且每个消息都有不同的 xml 元素名称。所以我需要一个通用函数，而不是为每个函数创建一个特定的函数。
I followed that suggestion(s): Extract SOAP body from a SOAP message
我遵循了该建议：从 SOAP 消息中提取 SOAP 正文
but with this code below, but it doesnt work for me. where am I doing the mistake or how do I extract inside the body part?
但是使用下面的代码，但它对我不起作用。我在哪里做错了或者我如何提取身体部位？
Dim myXDocument As XDocument = XDocument.Load(New StringReader(Request))
Dim Xns As XNamespace = XNamespace.Get("soap="http://www.w3.org/2003/05/soap-envelope")
SoapBody = myXDocument.Descendants(Xns + "Body").First().ToString

You have the wrong namespace in your second example, and you didn't follow the complete example from the linked answer.
您在第二个示例中使用了错误的命名空间，并且您没有遵循链接答案中的完整示例。
XNamespace.Get("soap="http://www.w3.org/2003/05/soap-envelope")
The parameter passed in to XNamespace.Getshould be the URI only:
传入的参数XNamespace.Get应该只是 URI：
XNamespace.Get("http://www.w3.org/2003/05/soap-envelope")
Then your second example will return something like:
然后你的第二个例子将返回如下内容：
<soap:Body xmlns:soap="http://www.w3.org/2003/05/soap-envelope">
<Request ReqRespVersion="large" Version="1" EchoToken="1.0" xmlns="http://mynamespace.com">
</Request>
</soap:Body>
If you want just the child(ren) elements of the Body, then you need to add FirstNodelike this:
如果你只想要 的 child(ren) 元素Body，那么你需要FirstNode像这样添加：
SoapBody = myXDocument.Descendants(Xns + "Body").First().FirstNode.ToString()
Which will give you this:
这会给你这个：
<Request ReqRespVersion="large" Version="1" EchoToken="1.0" xmlns="http://mynamespace.com">
</Request>
