使用 python 和 lxml 解析 vcxproj

Parsing vcxproj with python and lxml

我正在尝试使用 Python 和 lxml 解析 vcxproj。当我尝试这样做时,除非我删除 <Project >.

中的内容,否则打印期间不会显示任何内容

这是我的 .vcxproj(我将其缩减为测试):

<?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>

还有我的 python 代码:

#!/usr/bin/python3
# -*- coding: utf-8 -*-

from lxml import etree

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

for conf in tree.xpath("/Project/ItemGroup/ProjectConfiguration/Configuration"):
    print(conf.text)

如果我 运行 喜欢这样,脚本可以运行但什么也不显示。如果我删除节点 Project 中的 DefaultTargets="Build" ToolsVersion="14.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" 脚本工作...

我是 xml 的新手,也许我做错了什么。你能帮我解决这个问题吗?

感谢您的帮助。

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

看来,我必须像那样精确命名空间(如果有的话):

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)
