embedding a headless browser in C

Question

Is any of env-js, phantom JS, slimmerJS or any of the headless browsers embeddable in a C application? This is what I need to do: I have a C application that connects to a couple of servers through HTTP & HTTPS. Up until now, I got every page, figured out what it did, (mainly Javascript), extracted the parts of code that I needed (I also implemented a very simple string parser/extracter) and implemented the flow by sending the HTML code through a (secure)Socket and reading back the response. That part still works smoothly.

That was until I bumped into a set of very complex (read: obfuscated and looong) javascript pages linked one after the other, with several scripts included, and server side programming, and then I realized that I wouldn't be able to get a "maintainable" program with the procedure I've taken.

So I have spent the last several days looking for an embeddable Javascript interpreter. Bumped into spider monkey which is embeddable in C, but since I don't have any control over the scripts received, its lack of the DOM implementation makes it unsuitable. I also considered implementing the DOM interface, but honestly is a way too long distraction from my main proyect.

Then I considered the headless browsers mentioned above. Have read all the information I found about them, looked for some sort of library to interface with them, and in abscence of such librarys, have considedered hacking the code, only to realize that even trying to hack phantomJS to embedded it in my C system would be even crazier than implementing the DOM interface in spider monkey.

The system currently works in Windows and I'm using MinGW to develop it, but its final target is to be implemented in a Raspberry PI, so the more I can have plain straight C source code, the easier it will be to move the system to its final destination. With this I mean: I can use windows libraries in the meantime if they are pre-built, but can't miss the need that they must be compilable and generated in a plain compiler. I don't have yet the Raspberry PI, but I'm not expecting any fancy development tool set (I might be wrong on this)

Lastly, for the curious inside, the system is a stock screener, generates graphics with indicators which are put in a web server and generates alerts (to send notifications of price conditions) through Yahoo Messenger (this choice was mainly due to portability and availability of source code).

I will really appreciate your help in find a way to implement/embed in C *any* Javascript interpreter that has a DOM interface implemented.
