如何从元素中删除所有属性 [英] How to remove all attributes from element

问题描述

如何删除整个文档中特定元素的所有属性.我正在尝试这样的事情:

How to remove all attributes of the specific elements througout the document. I'm trying something like this:

from bs4 import UnicodeDammit
from lxml import html

content = open("source.html").read()
document = UnicodeDammit(content, is_html=True)
parser = html.HTMLParser(encoding=document.original_encoding)
root = html.document_fromstring(content, parser=parser)

for attr in root.xpath('.//table/@*'):
    del attr.attrib

在这里，我尝试使用xpath从文档的所有表中删除所有属性，但这不起作用.

Here I'm trying to delete all attributes from all tables in the document using xpath, but it doesn't work.

推荐答案

这是一种可能的方法，假设您要删除某些元素的 all 属性，例如table:

This is one possible way, assuming that you want to remove all attributes of certain element, say table :

for table in root.xpath('//table[@*]'):
    table.attrib.clear()

上面的代码循环遍历包含任何属性的所有table，然后调用elemet的attrib属性的clear()方法，因为该属性只是一个python字典.

The code above loop through all table that contains any attribute, then call clear() method of the elemet's attrib property, since the property is simply a python dictionary.
