    scan for lines

    apply for example:

    if(preg_match("/\/p\//i", $line)) {

    and also

    if(preg_match("/class=\"price\"/i", $line)) {

    then you can use explode() to get the content of a href or the content inside <p>

    For scraping HTML code, it is wise to not use regex as the HTML is more complex than that.

    You could use DOM or XPATH for this

    Malformed HTML don't always work with XPATH. This is a great library.
    I've never seen in break and ran some nasty crap thru it.
