I'm searching a textarea that has been split into an array of lines. I'm
looking for certain keywords that are centered like headings, or all by
themselves on a line, right or left justified. They may also be
scattered in the text within sentences, but I don't want those occurrences.
The logic I am using may be summarized like so:
if(
($textarea_line =~ m/^\s*(Exhibit\s+[\d.]+(\s*\([0-9a-zA-Z]+\))*)\s*$/i) ||
($textarea_line =~ m/^\s*(FORM\s+10\-K)\s*$/i) ||
($textarea_line =~ m/^\s*(FORM\s+10\-K[A-Z]*\/*[A-Z]*)$/i) ||
($textarea_line =~ m/^\s*(FORM\s+8\-K)\s*$/i) )
I was using the index function to get the position of the particular
heading that triggered the match:
$heading = $1;
$heading_offset = index($textarea, $heading);
Being the rocket scientist I am, it took me all morning to figure out
why I was getting inaccurate results. Then I finally went back to the
manual and re-discovered that index returns the position of the FIRST
occurrence of substring within string.
First occurrence doesn't help me. I need, naturally, the exact
occurrence (whether the fifth or the hundredth) that triggered the match.
Any suggestions?
