用python的lxml剥离内联标签

用python的lxml剥离内联标签

我想

strip_tags

和

strip_elements

你在每一种情况下想要的东西。例如，此脚本：

from lxml import etreetext = "<x>hello, <z>keep me</z> and <y>ignore me</y>, and here's some <y>more</y> text</x>"tree = etree.fromstring(text)print etree.tostring(tree, pretty_print=True)# Remove the <z> tags, but keep their contents:etree.strip_tags(tree, 'z')print '-' * 72print etree.tostring(tree, pretty_print=True)# Remove all the <y> tags including their contents:etree.strip_elements(tree, 'y', with_tail=False)print '-' * 72print etree.tostring(tree, pretty_print=True)

…产生以下输出：

<x>hello, <z>keep me</z> and <y>ignore me</y>, andhere's some <y>more</y> text</x>------------------------------------------------------------------------<x>hello, keep me and <y>ignore me</y>, andhere's some <y>more</y> text</x>------------------------------------------------------------------------<x>hello, keep me and , andhere's some  text</x>
