All,
I have a question pertaining to traversing up/down lines once you've matched your $string.

You can find the scenario I'm dealing at this URL: http://soc.our.psu.edu/soc/fall/up/i-o/ist.html

Basically -- I wrote a script to track classes I need to register. It does the whole bit -- emails me when a slot opens, etc. I'm using the schedule number as my matching $string. So $string gets me to the line that holds all of the info for the particuliar class. The only info I cannot get from that line is the actual name of the class.

Example:
$string = "335794";
$_ = /$string/;
This would get me the line of the output which has 335794. Then from there I can do regex to parse out all of the data, such as remaining seats.
My question is how would I then traverse up x number of lines to get the class name, being "IST 230" in this scenario. The number x will not be a set number seeing as each class has a different number of sections available.

Background Info:
I'm using w3m -dump $url to get the output of the page. The -dump option just spits out what the page actually looks like -- it does NOT output the HTML source.

Thank you anyone who can help me out with this.
