使用 lxml 是否可以递归地找到标签"f1 "?我尝试了 findall 方法,但它只适用于直系子女.
Using lxml is it possible to find recursively for tag " f1 "? I tried findall method but it works only for immediate children.
我想我应该为此选择 BeautifulSoup !!!
I think I should go for BeautifulSoup for this !!!
可以使用XPath递归搜索:
You can use XPath to search recursively:
>>> from lxml import etree
>>> q = etree.fromstring('<xml><hello>a</hello><x><hello>b</hello></x></xml>')
>>> q.findall('hello') # Tag name, first level only.
[<Element hello at 414a7c8>]
>>> q.findall('.//hello') # XPath, recursive.
[<Element hello at 414a7c8>, <Element hello at 414a818>]
