i have file multiple doc tags. each doc tag has docid tag inside it. need inside doc tag if docid tag matches. using htmlparser parse file.
need is:
1. recursively iterate on doc tag.
2. each doc tag if docid tag inside matches under doc tag.
3. repeat 2nd step doc tags.

def get_docs(self, filepaths):      parser = etree.htmlparser()     file in filepaths:         tree = etree.parse(file, parser)         # tree = etree.parse(file)         doc = tree.findall('.//doc')         elem in doc:             print etree.tostring(elem)

i trying content inside each doc tag text_content() failing. getting below error while doing
attributeerror: 'lxml.etree._element' object has no attribute 'text_content'
