I've tried to use to DomCrawler as web scraper, but find it somewhat 
confusing and unintuitive. I believe this might just as well be me 
misunderstanding it's intended use.

Anyway, is the DomCrawler mostly intended for functional testing, or is it 
meant to be more full fledged "web browser" (or web page reader). I 
especially find it hard to extract either the whole document or the 
html/xml-representation of a node. I believe it would be quite easy to add 
this functionality (and I would be happy to do it), but I wonder if this 
within the intended scope of the DomCrawler Component.

The README.md and 
docs<http://symfony.com/doc/current/components/dom_crawler.html> suggests 
that the DomCrawler is kind of jQuery for PHP. However, it currently lacks 
of lot functionality to achieve this goal. I would be happy to take a look 
and add functionality to make it more powerful.


PS.: As someone who does not follow all the discussions and commits (or 
barely any), I find it hard to find out the intention behind certain 
components, and what's the roadmap/planned/wanted feature set of each. Is 
the dev-mailing list the place to go for this kind of info?
