Re: [cssparser-developers] Migrating from CSS4J

[Ronald B. <rb...@rb...>]

Hi Vincent,

thanks for considering CSSParser as alternative solution.
CSSParser is a smaller/more focused solution; only parsing the css into some tree sturcture is the current focus of the project. There is no support to parse (X)Html and also no 
help for mixing the two trees into one.
As far as i know there are two main use cases for CSSParser at the moment:
* parsing a css for error detection or optimization and optional writing back the optimized version (The cleanup/optimization is not part of CSSParser)
* parsing a css to support html processing

The second case is what is done by HtmlUnit (i'm also involved with this project). HtmlUnit uses NekoHtml to parse (X)Html and CSSParser for css. Then HtmlUnit uses both 
informations to simulate real browser behavior.
If you like i can think a bit if your use case is someting that can be done with HtmlUnit - give me a sign and i will have a look ;-)

Outside of this i'm a bit curious about your case. Usually the css is separated from the Html by idea. Why you like to merge this?
