解析HTML/XML并查找原始文档中元素的位置 [英] Parse HTML/XML and find locations of elements in original document

问题描述

有没有一种方法可以获取元素在文档中的原始位置，即.在Python中解析html/xml时的开始和结束字符索引?

Is there a way to get the original location of an element in a document, ie. the start and end character index, when parsing html/xml in Python?

我浏览了lxml文档，找不到任何东西.

I've looked through the lxml documentation and couldn't find anything.

例如

<a>1</a><b>2</b>

...

print tree.find('b').original_position
# result: (9, 16)

推荐答案

Google找到了

Google found this, the gist of which is: it's hard for malformed documents because parsing requires synthesizing valid tokens that don't have any corresponding input. It's possible for valid documents, but most parsing libraries don't support it.
