* Notacion de las variables:
* i_ = integer, ex: i_count
* a_ = array, a_html
* b_ = boolean,
* s_ = string
*
* Que hace esta función:
* - analiza una cadena HTML y extrae los tags con su atributos
* - exceptions: los tags html como <br> <hr> </a>, etc
* - Al finalizar, devuelve un array de este tipo:
* ["IMG"][0]["SRC"] = "xxx"
* ["IMG"][1]["SRC"] = "xxx"
* ["IMG"][1]["ALT"] = "xxx"
* ["A"][0]["HREF"] = "xxx"
