Need to extract text between two HTML comments

[mmk16]

I need to extract all text in a HTML page between two patterns like
<!-- cachedResultsStart --> and <!-- cachedResultsEnd -->.

I am trying something like

my $start_tag = '<!-- cachedResultsStart -->';
my $end_tag = '<!-- cachedResultsEnd -->';

my $num_lines = /$start_tag/ .. /$end_tag/ ;

if ($num_lines ) {
/$start_tag(.+?)$end_tag/m ;
$this_is_what_i_need = $1 ;

}

print $this_is_what_id_need ;

I used this approach from an earlier posting by Uri Guttman
However, this is not working for me.

Okay. Would you mind letting us know what you are actually trying?

$this_is_what_i_need = $1 ;

print $this_is_what_id_need ;

One of these things is not like the other, one of these things
just isn't the same...


Imagine all the time you would have saved if you had "use strict"
turned on. It would have found that problem right away.

Imagine all the time you would have saved _us_ if you had asked
for a machine's help *before* asking thousands of people for help.

/$start_tag(.+?)$end_tag/m ;

The "m" modifier is a no-op there. It does nothing.

Perhaps you meant //s instead?

and he is blaming ME for inspiring him. i tend to strictness and win all
my variable spelling bees.

i ask for help from my machine all the time but it still can't tell me
the picks for the next powerball drawing.

Between <!-- cachedResultsStart --> and <!-- cachedResultsEnd -->
the html page will contain a HTML table with data that I am
interested in. I wish to further process this using HTML::TableExtract

Working with HTML can be some scary rocket science, but here goes:

my $start = '<!-- cachedResultsStart -->';
my $end = '<!-- cachedResultsEnd -->';
if ( $html =~ m,$start(.*)$end,g ) {
print $1;
}

No need to know how many lines or anything like that. Just grab what you
need.

Problems arise, however, if the HTML code contains more than one occurance
of the expression above. That's when you should consider doing a while()
to match all of them.

May I suggest using the HTML:arser module, specifically the
HTML:ullParser which will easily allow you to get what you want
