This is untested, but I think this should do the trick: 
for($i=0; $i<$glob; $i++){
    $_ = @text[$i];
    if(/href="?([^">]*)\?eid=/is){
    $counter = 1 - $counter;
        print $1 if $counter;
    }
}

Explanation:
"?
The quote mark is optional
([^">]*)
The parens say to snag everything. The [^">]* quantifies 'everything' as being any character that isn't a quote or an end-bracket.
\?eid=
This is the key phrase
I'd include more code, but it's prone to errors. The href="? marks the beginning of your search pattern, and the \?eid= marks the end. If it doesn't have an eid, it should return everything within parens to the special regex string $1.

Update: I added the "is" options to the regex to allow uppercase URLs also. No biggie.

Update 2: Forgot that CODE tags don't need entity substitution, so I had &gt; in one part instead of just >. I fixed it; sorry if I confused anyone.
