具有名称空间的元素的XPath

本文介绍了具有名称空间的元素的XPath的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

元素

<dependentAssembly>
<assemblyIdentity name="System.Reactive.Linq" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-2.2.5.0" newVersion="2.2.5.0" />
</dependentAssembly>

我已经尽力做到了自己.但是不知道如何为带有名称空间的元素获取XPATH.它非常令人困惑.有人请给我一个XPATH.

I have tried my best to do it by myself. But don't know how to get XPATH for elements with namespace. Its very confusing. Somebody please provide me a XPATH.

XPATH是

/configuration/runtime/assemblyBinding/dependentAssembly[2]/bindingRedirect[@newVersion='2.2.5.0']/@newVersion


<?xml version="1.0" encoding="utf-8"?>
<configuration>
<runtime>
<legacyUnhandledExceptionPolicy enabled="1" />
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <dependentAssembly>
    <assemblyIdentity name="System.Reactive.Interfaces" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect name="Test1" oldVersion="0.0.0.0-2.2.5.0" newVersion="2.2.5.0" />
  </dependentAssembly>
  <dependentAssembly>
    <assemblyIdentity name="System.Reactive.Linq" publicKeyToken="31bf3856ad364e35" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-2.2.5.0" newVersion="2.2.5.0" />
  </dependentAssembly>
</assemblyBinding>

推荐答案

正确的xpath是

XPATH:

/configuration/runtime/ns:assemblyBinding/ns:dependentAssembly[ns:assemblyIdentity[@name='System.Reactive.Linq']]/ns:bindingRedirect/@newVersion

其中ns是命名空间urn:schemas-microsoft-com:asm.v1

我在项目文件的MSBuild任务中使用XmlPoke任务来修改绑定重定向.连同XmlPoke Task一起，代码如下:

I use a XmlPoke Task in the MSBuild tasks in the project file to modify the binding redirect.Together with a XmlPoke Task the code goes like this:

 <XmlPoke XmlInputPath="$(DestXmlFiles)"
          Namespaces="&lt;Namespace Prefix='ns' Uri='urn:schemas-microsoft-com:asm.v1' Name='DoNotKnowWhatThisIsFor-ButItIsRequired' /&gt;"
          Query="/configuration/runtime/ns:assemblyBinding/ns:dependentAssembly[ns:assemblyIdentity[@name='System.Reactive.Linq']]/ns:bindingRedirect/@newVersion"
          Value="$(BUILD_NUMBER)"/>
