Teddy,
Well, this works, I've tested it,
---------------------------------------
my $test = qq^
<a href="/index.shtml"
title="index file">
Index
</a>
<a href="/about.shtml"
title="about my site">
About
</a>
^;
$test =~ s/href\=\"(.*?)\"/href\=\"another_text_$1\"/g;
print $test;
-----------------------------------------
The reason the other even with an /s did not work was because we told it to treat
the whole text
as a single line when running the expression on it, but that doesn't mean it stripped
out the line
breaks. Basically it just chose to ignore their function, but the line breaks
themselves are still
in there as valid characters. So, there are two solutions. The one above where you
only check the
href="(.*?)" part, or you could strip out [\n\r]+ from the string before running your
pattern match
on it. There was one last problem. What you gave was href="(.*)" which does not have
a question
mark. The question mark tells the expression to not be greedy which means that the .*
will not stop
matching when it finds the next quote, not the last quote. So where in your case, you
had multiple
links, it was finding the last quote in the whole string, not the closing quote of
that particular
href= .

David

Unfortunately it doesn't work this way.
I've tried using the /s modifier in the following example, and only the
first <a href="..."> is modified.
my $test = qq^
<a href="/index.shtml"
title="index file">
Index
</a>
<a href="/about.shtml"
title="about my site">
About
</a>
^;
$test =~ s/<a href="(.*)">/<a href="another_text_$1">/gs;
print $test;

my $stuff = qq^
here is some stuff
and more stuff to boot
stuff for me
and stuff for you
^;
$stuff =~ s/stuff/money/gs;
# g says match all occurrences
# s says treat $stuff as a single line

Hi all,
I want to use regular expressions to match all the links from a web page.
I am fighting for a long time but with no results.
I don't know what modifiers I need to use for matching all the links even
though some of them use multiple lines.
I want to also match a link like:
<a href=http://www.server.com/dir/file.shtml
title="Test link">
This is a test only
</a>
Without the /m modifyer, my regexp matches only the first link that is on a
single line.
With the /m modifyer, the regexp matches all the links that don't span on
multiple lines.
But the links that span on multiple lines can't be matched.
I've tried the following regexp:
$link =~ s/(<a href=".*">)/<a
href="http\:\/\/MyServer\.com\/cgi-bin\/script\.pl\?page=$1">/mgi;
Thank you for any idea.
