使用python和lxml模块从html删除所有javascript标签和样式标签

使用python和lxml模块从html删除所有javascript标签和样式标签

下面是执行所需 *** 作的示例。对于HTML文档，

Cleaner

比使用更好的解决方法是使用

strip_elements

，因为在这种情况下，您不仅要剥离

<script>

标签，还应剥离更多标签。您还想摆脱

onclick=function()

其他标签上的属性之类的东西。

#!/usr/bin/env pythonimport lxmlfrom lxml.html.clean import Cleanercleaner = Cleaner()cleaner.javascript = True # This is True because we want to activate the javascript filtercleaner.style = True      # This is True because we want to activate the styles & stylesheet filterprint("WITH JAVAscript & STYLES")print(lxml.html.tostring(lxml.html.parse('http://www.google.com')))print("WITHOUT JAVAscript & STYLES")print(lxml.html.tostring(cleaner.clean_html(lxml.html.parse('http://www.google.com'))))

您可以在lxml.html.clean.Cleaner文档中获得可以设置的选项的列表；您可以将某些选项设置为

True

或

False

（默认），而其他选项则采用以下列表：

cleaner.kill_tags = ['a', 'h1']cleaner.remove_tags = ['p']

注意kill和remove之间的区别：

remove_tags:  A list of tags to remove. only the tags will be removed, their content will get pulled up into the parent tag.kill_tags:  A list of tags to kill. Killing also removes the tag's content, i.e. the whole subtree, not just the tag itself.allow_tags:  A list of tags to include (default include all).
