I wrote this a few years ago as part of bigger project. After examining HandsomeSoup, I found that it produces incorrect results in many cases (e.g. the > relation or the :first-child pseudo class do not work correctly, or sometimes it returns non element nodes which is not allowed by the css spec), it supports a more limited subset of CSS (than hxt-css) and has unrelated dependencies (such as HTTP). Since I had already written this code, I decided to release it as a stand alone package even though there was a similar package in hackage already.

Cool, I was just wondering. I will consider switching to hxt-css next time I work on one of my projects using HandsomeSoup. I'm not a heavy user of it (in fact I try very hard to have as little to do with web things as possible) so I never noticed it behaved badly, good to know!

Hello everybody,

I'd like to announce the first public release of hxt-css, a CSS selector engine for the Haskell XML Toolbox (HXT). Its main design goals are:

* support as many CSS selectors as possible: it currently supports all CSS 3 selectors except the ones that do not make sense outside a web browser (e.g. such as :hover). For example, it supports weird things like

div > span + p:not(:nth-of-type(3n-1))

* try to be 100% correct: in all tests I ran, the output of hxt-css was identical to that of firefox & chrome.

* follow the conventions of other hxt packages: for example, error reporting is done the same way as hxt-xpath.

Note, there is already a similar package in hackage called HandsomeSoup.

Can you explain how this differs from HandsomeSoup?
