* My notation of variables:
* i_ = integer, ex: i_count
* a_ = array, a_html
* b_ = boolean,
* s_ = string
*
* What it does:
* - parses a html string and get the tags
* - exceptions: html tags like
, etc
* - At the end, the array will look like this:
* ["IMG"][0]["SRC"] = "xxx"
* ["IMG"][1]["SRC"] = "xxx"
* ["IMG"][1]["ALT"] = "xxx"
* ["A"][0]["HREF"] = "xxx"
