Python XML解析

本文介绍了Python XML解析的处理方法，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

*注意:lxml将无法在我的系统上运行.我希望找到一种不涉及lxml的解决方案.

*Note: lxml will not run on my system. I was hoping to find a solution that does not involve lxml.

我已经阅读了一些此处的文档，并且很难按照我的意愿来进行操作.我想解析一些看起来像这样的XML文件:

I have gone through some of the documentation around here already, and am having difficulties getting this to work how I would like to. I would like to parse some XML file that looks like this:

<dict> <key>1375</key> <dict> <key>Key 1</key><integer>1375</integer> <key>Key 2</key><string>Some String</string> <key>Key 3</key><string>Another string</string> <key>Key 4</key><string>Yet another string</string> <key>Key 5</key><string>Strings anyone?</string> </dict> </dict>

在我要操作的文件中，此命令之后还有更多的"dict".我想通读XML并输出看起来像这样的text/dat文件:

In the file I am trying to manipulate, there are more 'dict' that follow this one. I would like to read through the XML and output a text/dat file that would look like this:

1375，某些字符串"，另一个字符串"，又一个字符串"，有人字符串吗?"

1375, "Some String", "Another String", "Yet another string", "Strings anyone?"

...

** 最初，我尝试使用lxml，但是在尝试使其在我的系统上运行之后，我继续使用DOM.最近，我尝试使用Etree来完成此任务.拜托，因为对所有美好事物的热爱，有人会帮助我吗?我是Python的新手，想学习它的工作原理.我先谢谢你.

** Originally, I tried to use lxml, but after many tries to get it working on my system, I moved on to using DOM. More recently, I tried using Etree to do this task. Please, for the love of all that is good, would somebody help me along with this? I am relatively new to Python and would like to learn how this works. I thank you in advance.

推荐答案

您可以使用 xml.etree.ElementTree (Python随附).有一个随附的C实现(即更快)xml.etree.cElementTree. lxml.etree提供了功能的超集，但是您不需要做什么.

You can use xml.etree.ElementTree which is included with Python. There is an included companion C-implemented (i.e. much faster) xml.etree.cElementTree. lxml.etree offers a superset of the functionality but it's not needed for what you want to do.

@Acorn提供的代码对我来说(Python 2.7，Windows 7)与以下每个导入均相同:

The code provided by @Acorn works identically for me (Python 2.7, Windows 7) with each of the following imports:

import xml.etree.ElementTree as et import xml.etree.cElementTree as et import lxml.etree as et ... tree = et.fromstring(xmltext) ...

您正在使用什么操作系统以及lxml遇到了哪些安装问题?

What OS are you using and what installation problems have you had with lxml?
