问题
I need to browse the DOM tree of a parsed HTML document.
I'm using uTidyLib before parsing the string with lxml
a = tidy.parseString(html_code, options) dom = etree.fromstring(str(a))
sometimes I get an error, it seems that tidylib is not able to repair malformed html.
how can I parse every HTML file without getting an error (parsing only some parts of files that can not be repaired)?
回答1:
Beautiful Soup does a good job with invalid/broken HTML
>>> from BeautifulSoup import BeautifulSoup
>>> soup = BeautifulSoup("<htm@)($*><body><table <tr><td>hi</tr></td></body><html")
>>> print soup.prettify()
<htm>
<body>
<table>
<tr>
<td>
hi
</td>
</tr>
</table>
</body>
</htm>

Since you are already using lxml, have you tried lxml's ElementSoup module?
If ElementSoup can't repair the HTML then you'll probably need to apply your own filters first that are based on your own observations of how the data is broken.
