用python和lxm解析vcxproj

Question

我试图用Python和lxml解析vcxproj。当我尝试这样做时，除非我删除<Project >中的内容，否则在打印过程中不会出现任何内容。在

这是我的.vcxproj（我将其简化为测试）：

<?xml version="1.0" encoding="utf-8"?>
<Project DefaultTargets="Build" ToolsVersion="14.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <ItemGroup Label="ProjectConfigurations">
    <ProjectConfiguration Include="Debug|Win32">
      <Configuration>Debug</Configuration>
      <Platform>Win32</Platform>
    </ProjectConfiguration>
    <ProjectConfiguration Include="Debug|x64">
      <Configuration>Debug</Configuration>
      <Platform>x64</Platform>
    </ProjectConfiguration>
    <ProjectConfiguration Include="ReleaseDebug|Win32">
      <Configuration>ReleaseDebug</Configuration>
      <Platform>Win32</Platform>
    </ProjectConfiguration>
    <ProjectConfiguration Include="ReleaseDebug|x64">
      <Configuration>ReleaseDebug</Configuration>
      <Platform>x64</Platform>
    </ProjectConfiguration>
    <ProjectConfiguration Include="Release|Win32">
      <Configuration>Release</Configuration>
      <Platform>Win32</Platform>
    </ProjectConfiguration>
    <ProjectConfiguration Include="Release|x64">
      <Configuration>Release</Configuration>
      <Platform>x64</Platform>
    </ProjectConfiguration>
  </ItemGroup>
</Project>

以及我的python代码：

^{pr2}$

如果我这样运行，脚本会起作用，但不会显示任何内容。如果我在nodeProject脚本中删除DefaultTargets="Build" ToolsVersion="14.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"，脚本会起作用。。。在

我是xml新手，也许我做错了什么。你能帮我解决这个问题吗？在

谢谢你的帮助。在

在此处找到解决方案：lxml etree xmlparser remove unwanted namespace

似乎，我必须在名称空间之前（如果有）像这样精确：

from lxml import etree

tree = etree.parse("core.xml")

namespaces = {'ns':'http://schemas.microsoft.com/developer/msbuild/2003'}
for conf in tree.xpath('//ns:Configuration', namespaces=namespaces):
    print (conf.text)
