Gee, I saw the reply count was up and almost did not stop to see this post. But, curiosity got the best of me and I wanted to see what your question was. I will use backslashes to try to keep the comments from disappearing in the post.
Here is the example I tested:
my $htmlText = qq~
<h3>Some html</h3>
<h4>Don't know what to show</h4>
this text
is not
to be
displayed
<!-- but here is a comment ending -->
This text should show
~;
# assume $htmlText is read in line by line from file and stuffed
# in array, then Result would be something like:
my @html = split(/\n/, $htmlText);
my @cleanedHtml;
my $hideFlag = 0;
while (@html){
$pattern = "\<\!\-\-(.+?)\-\-\>";
my $line = shift @html;
if ($hideFlag){
$hideFlag = 0 if $line =~ /$pattern/;
next;
}
if (!$hideFlag){
if ($line =~ /$pattern/){
$hideFlag = 1;
next;
}
else {
push @cleanedHtml, $line;
}
}
}
print join "\n", @cleanedHtml;
Will attach .txt file also. After previewing the post, I am afraid I will miss something in the translation.
HTH,
Dennis
