Retrieving Content

Hi guys, I'm trying to retrieve a certain variable from a site. Here it goes:

The site has a SELECT box that is dynamicaly updated, I need to put a
script running that will retrieve the specified SELECT with its
contents, that are labels and values. Is there a way to retrieve the
page and then select just one line of the code, discard the rest and
then retrieve from this line the values?

Here goes the SELECT :

<SELECT title='navigation' Name=navigating onChange="self.location =
'/s/2318355/'+ this.options[this.selectedIndex].value + '/';"><option
value=1 selected>1. Name<option  value=2 >2. Name</select>


I need to get something like this:
$select = navigating;
$label1 = "1.Name";
$value1 = 1;
$label2 = "2.Name";
$value2 = 2;


Remmembering that the SELECT is dynamic so I need also to check how
many labels and values there are and store them into variables. I
getting a really hard time doing this.


I thank any imput you guys can give me.

Thanx,
Rodrigo
