xml - SOAP 响应中的 XPath 查询有什么问题

Question

我需要创建一个 xpath 查询，它将返回可用性元素下列出的所有内容。

    <?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>
           <GetAvailableTimesResult xmlns="http://schemas.test.net/x/version2/2007/06/" resultcode="SearchOk">
      <Availability>
        <Result available="true" time="2011-10-17T17:00:00"/>
        <Result available="true" time="2011-10-17T17:15:00"/>
        <Result available="true" time="2011-10-17T17:30:00"/>
        <Result available="true" time="2011-10-17T17:45:00"/>
        <Result available="true" time="2011-10-17T18:00:00"/>
        <Result available="true" time="2011-10-17T18:15:00"/>
        <Result available="true" time="2011-10-17T18:30:00"/>
        <Result available="true" time="2011-10-17T18:45:00"/>
        <Result available="true" time="2011-10-17T19:00:00"/>
        <Result available="true" time="2011-10-17T19:15:00"/>
        <Result available="true" time="2011-10-17T19:30:00"/>
        <Result available="true" time="2011-10-17T19:45:00"/>
        <Result available="true" time="2011-10-17T20:00:00"/>
        <Result available="true" time="2011-10-17T20:15:00"/>
        <Result available="true" time="2011-10-17T20:30:00"/>
        <Result available="true" time="2011-10-17T20:45:00"/>
        <Result available="true" time="2011-10-17T21:00:00"/>
        <Result available="true" time="2011-10-17T21:15:00"/>
        <Result available="true" time="2011-10-17T21:30:00"/>
        <Result available="true" time="2011-10-17T21:45:00"/>
        <Result available="true" time="2011-10-17T22:00:00"/>
        <Result available="true" time="2011-10-17T22:15:00"/>
        <Result available="true" time="2011-10-17T22:30:00"/>
             </Availability>
                 </GetAvailableTimesResult>
       </soap:Body>
 </soap:Envelope>

我的xpath查询返回malformed xpath expression错误信息，查询如下:

//xsi:[soap:body]//Availability

Answer 1

您需要在 XPath 引擎中为 http://schemas.livebookings.net/Ingrid/version2/2007/06/ 命名空间定义前缀，例如前缀 a，然后:

//a:Availability

它将选择 a:Availability 元素。

或者您可以使用这个 XPath:

//*[local-name() = 'Availability']
