=== `ExtractImageLinks` ===
This adaptor may receive either XPathSelectors pointing to the desired locations for finding image urls, or just a list of XPath expressions (which will be turned into selectors anyway).
'''Decision''': XXX
== markup.py ==
=== `remove_tags` ===

'''Decision''': XXX
== misc.py ==
=== `to_unicode` ===
Receives a string and converts it to unicode using the given encoding (if specified, else utf-8 is used) and returns a new unicode object. E.g:
{{{
>> to_unicode('it costs 20\xe2\x82\xac, or 30\xc2\xa3')
[u'it costs 20\u20ac, or 30\xa3']
}}}
'''Decision''': XXX
=== `clean_spaces` ===
