问题 I am generating some XML with lxml and getting nodes generated like this: <QBXML xmlns:py="http://codespeak.net/lxml/objectify/pytype" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" py:pytype="TREE"> and: <MaxReturned py:pytype="int"> These custom attributes are killing Quickbooks' parser. Can I get LXML to render without the custom stuff? 回答1: Looks like the following take care of it: objectify.deannotate(root, xsi_nil=True) etree.cleanup

一、介绍 Beautiful Soup 是一个可以从HTML或XML文件中提取数据的Python库.它能够通过你喜欢的转换器实现惯用的文档导航,查找,修改文档的方式.Beautiful Soup会帮你节省数小时甚至数天的工作时间.你可能在寻找 Beautiful Soup3 的文档,Beautiful Soup 3 目前已经停止开发,官网推荐在现在的项目中使用Beautiful Soup 4, 移植到BS4 #安装 Beautiful Soup pip install beautifulsoup4 #安装解析器 Beautiful Soup支持Python标准库中的HTML解析器,还支持一些第三方的解析器,其中一个是 lxml .根据操作系统不同,可以选择下列方法来安装lxml: $ apt-get install Python-lxml $ easy_install lxml $ pip install lxml 另一个可供选择的解析器是纯Python实现的 html5lib , html5lib的解析方式与浏览器相同,可以选择下列方法来安装html5lib: $ apt-get install Python-html5lib $ easy_install html5lib $ pip install html5lib 二、基本使用 html_doc = """ <html>
