Get the value from a SOAP message in Java
提问by vs777
I am getting a SOAP message as a string after making a call to the web service.
在调用 Web 服务后，我收到了一个字符串形式的 SOAP 消息。
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<soap:Body>
<PassOracleXMLDataResponse xmlns="http://tempuri.org/">
<PassOracleXMLDataResult>
<gesystem xmlns="">
<return_code>0</return_code>
<message>PRS User does not exists in GETS</message>
<invoiceid>TESTADDTLINFO2</invoiceid>
<datetime>Apr 17 2013 4:19PM</datetime>
</gesystem>
</PassOracleXMLDataResult>
</PassOracleXMLDataResponse>
</soap:Body>
</soap:Envelope>
I need to retrieve the values and elements. When I tried to use a simple SAXBuilder to build a Document and traverse it, I got an exception after trying to getChild on "soap: Body"
我需要检索值和元素。当我尝试使用一个简单的 SAXBuilder 来构建一个 Document 并遍历它时，我在“soap: Body”上尝试 getChild 后出现异常
getChild("soap:Body") - returns null.

Assuming you're using JDOM:
假设您使用的是 JDOM：
soap:Body is actually two parts: the namespace and the element name. You'll want to use the Namespace class to include that information when retrieving it.
soap:Body 实际上是两部分：命名空间和元素名称。在检索信息时，您需要使用 Namespace 类来包含该信息。
Try doing something like:
尝试执行以下操作：
envelopeNode.getChild("Body",envelopeNode.getNamespace());
That'll make it look for the child element with the name "Body", and the same namespace as the envelope node.
这将使它寻找名为“Body”的子元素，并且与包络节点具有相同的命名空间。

Thanks Peter, it worked. There is only one strange thing. When I was getting a child Element for "PassOracleXMLDataResult" it also required to provide a Namespace as a second parameter
谢谢彼得，它奏效了。只有一件奇怪的事情。当我为“PassOracleXMLDataResult”获取子元素时，它还需要提供一个命名空间作为第二个参数
Namespace nmspc = Namespace.getNamespace("http://tempuri.org/");
Element parseResponse = bodyEm.getChild("PassOracleXMLDataResponse", nmspc);
Element passResult = parseResponse.getChild("PassOracleXMLDataResult", nmspc);
