Example in docs wrong

[jonathaneunice]

Was just fiddling with the cssselect 0.2 package from PyPI. Noticed that the docs
claim a result that doesn't appear to be current/correct. In docs:

>>> from cssselect import css_to_xpath
>>> exrpession = css_to_xpath('div.content')
>>> exrpession
"descendant-or-self::div[contains(concat(' ', normalize-space(@class), ' '), ' content ')]"

What I got:

u"descendant-or-self::div[@class and contains(concat(' ', normalize-space(@class), ' '), ' content ')]"

(Differences: The u for unicode string and @class and expression.)

Thanks for the report.

The u prefix is irrelevant and depends on the Python version. (You won’t see it on Python 3.x.) The other difference was indeed a mistake in the docs.

cssselect was recently extracted from lxml; this is very much work-in-progress. This example was copied verbatim from the lxml docs. I think that the translation is correct both with and without the @class and part. It was probably added after the doc was written as a speed improvement.
