PHP: Get all lines containing specific text

Question

I'm trying to parse the source code from a website that goes like

   <html>
    ...
    ...
    ...
    <div class="menu_body">
    <a href="url" onclick="_gaq.push([parameters]);location.href=this.href+'?channelId=287&date='+dateOfMonth;return false;"> <img src="img"></a>
    <a href="url"><img src="img"></a>
    <a href="url"><img src="img"></a>
    </div>
    ...
    ...
    <div class="menu_body">
    <a href="url"><img src="img></a>
    <a href="url"><img src="img"></a>
    <a href="url"><img src="img"></a>
    </div>
    ...
    ...
    ...
    </html>

What I want to do if possible is to just grep out all the lines which contains channelId, not sure if it's possible?

How are you currently parsing this HTML? Could we see your PHP code? — BoltClock, Feb 09 '11 at 02:30
and of course you have permission from this site to use their content? — , Feb 09 '11 at 02:38
Currently I'm just saving their source code into a variable using `file_get_contents`. And yes I have permission. Or is there a simpler way for me to grep all the lines which contain `channelId`? Sorta new to php and not sure what functions there are — Gary, Feb 09 '11 at 02:41
By lines, you really mean lines? You really want the whole line, e.g. starting at position 0 ending with a newline character? You dont care about the HTML elements? — Gordon, Feb 09 '11 at 08:07

Read the html as a string using CURL or file_get_contents, and then use preg_match. http://php.net/manual/en/function.preg-match.php
