There is probably an easy way to do this, but I can't find it anywhere.

I want to match a regex only once in a long file of data.

The regex is this:

foreach my $line (@lines) {
 if ($line=~ m/<FILENAME>.*\.htm/) {$doc_title_temp=substr $line, 10;$
+doc_title=$doc_title_temp;print "Filename is $doc_title"};

{

But in one of the documents I was searching, it had this in there and it was matching on both, and assigning the variable value twice, so it ended up with the 2nd value

<FILENAME>dp198076_424b2-us2342673.htm

<FILENAME>dp198076_exfilingfees.htm

I always want to match on the first, so the only logic I need is to just match one time in the long file and not match again.
