XML + XPATH:任何使用默认命名空间的方法? [英] XML + XPATH: Any way to work with a default Namespace?

问题描述

我有一个 XML SOAP 结果:

I have a XML SOAP result:

<?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>
    <CreateCIInStockResponse xmlns="http://somenamespace.com/">
      <CreateCIInStockResult>
        <Status>OK</Status>
        <Data>SOMERESULT</Data>
      </CreateCIInStockResult>
    </CreateCIInStockResponse>
  </soap:Body>
</soap:Envelope>

如您所见，CreateCIInStockResponse 中定义的命名空间使用默认命名空间 - 未定义前缀.

As you can see, the namespace defined in CreateCIInStockResponse uses a default namespace - no prefix defined.

如果我们使用

/soap:Envelope/soap:Body/node()/node()/node()/text()

我是对的，没有办法 - 使用 XPath - 直接访问数据"的内容?

Am I right, that there is no way - using XPath - to access the content of "Data" directly?

我的问题是，我既不能修改对 webservice 的调用，也不能修改从 webservice 返回的结果.我所能做的就是使用 XPath 来获取我的数据.

My problem is, that I can neither modify the call to the webservice nor modify the result coming back from the webservice. All I can do is use a XPath to get my data out.

有什么建议吗?

推荐答案

Assign http://somenamespace.com/命名空间前缀，说def"，并在您的 XPath 表达式中使用它:

Assign http://somenamespace.com/ to a namespace prefix, say "def", and use that in your XPath expression:

/soap:Envelope/soap:Body/def:CreateCIInStockResponse/def:Data

/soap:Envelope/soap:Body/def:CreateCIInStockResponse/def:Data

如何分配前缀会因您的 XPath 处理器而异.

How to assign the prefix will vary depending on your XPath processor.

更新:如果不能选择指定前缀的替代方法:

Updated: Alternative approach if assigning a prefix is not an option:

/soap:Envelope/soap:Body/*[local-name()='CreateCIInStockResponse']/*[local-name()='Data']

为了绝对确保您正在访问您期望的元素，您可以添加 namespace-uri() = 'http://somenamespace.com/' 也是如此.

To make absolutely sure that you're accessing the elements you expect, you might add namespace-uri() = 'http://somenamespace.com/' as well.
