Howdy

I want to do a simple substitution in html files where I 
can append some string to URL's (inside anchor tag).

So the entire code is simply something like:

----------------------------------------------------------

#!/usr/bin/perl

while (<>) {
	s/href="([^"])+"/appendit($1)/eg;
	print $_;
}

sub appendit {
	my $url = shift;
	$url .= "?sid=blahblah";
	return $url;	
}

----------------------------------------------------------

I noticed that the $1, instead of it being the entire URL
inside the anchor tag (between <a href=" and  ">), is
usually just the last letter of that URL.

I'm confused.  Could someone help me so that I can just
take the whole URL inside the anchor tag and pass it or
refer to it?

Many thanks,

John Chung

Your code does more than simple substitution, it deletes everything not
in the parens.  Maybe that's what you want.

maybe perldoc perlrequick to start.
perldoc perlintro (header Regular Expressions)
perldoc perlfaq6
perldoc perlretut

The parens enclose only one character, one that is not a double-quote. 
The plus is looking for one or more copies of that character?

You need something more like:

s/(href=")(.*?)"/$1$2&sid=blah"/

Yours,

You misplaced your parentheses; in this case, the plus quantifier
modifies the grouping, not the character set.  Simplest fix is:

   s/href="([^"]+)"/appendit($1)/eg;

Although this still isn't correct, since you remove the "href" portion
of the tag as well.  Maybe:

   s/(href=")([^"]+)(")/$1 . appendit($2) . $3/eg;

Comments:

1. /e is slow, and potentially insecure.  Consider doing the
   replacement inline:

      s/(href=")([^"]+)(")/$1$2?sid=xxx$3/g;

2. The href url might already have a '?', so another one is incorrect
   (should be ";" or "&")

      s/(href=")([^"?]+)([^"]*)(")/$1 . $2 . ($3 ? "&" : "?" ) . "sid=xxx" . $4/eg;

3. HTML tag attributes are case-insensitive.  Consider using /i:

      s/(href=")([^"]+)(")/$1$2?sid=xxx$3/ig;

4. "href" is also used for IMG tags.  :)

This gets ugly in a hurry.  The slightly better answer is to parse
things out in more detail; a regex that you might find helpful is
discussed in:

   http://archive.lug.boulder.co.us/bymonth/2001.08/msg00573.html

Hopefully the tips above are enough to get you started, though.  If
your HTML is regular enough to begin with, then just moving the + to
be inside the parens should be enough.

Greetings! This is just to announce an informal gathering I'm
trying to organize to meet up with a NY monger/monk who's
coming through the area, Ben Tilly
(http://www.perlmonks.org/index.pl?node_id=26179),
whose troubles have been the subject of a slashdot article
(http://slashdot.org/article.pl?sid=02/03/21/0139244&mode=thread),
has been a very helpful and knowledgeable programmer
on perlmonks, and has helped develop some core perl
modules, including Carp and Exporter.

This is purely a social gathering, no presentations, and since I'm
in OC, and I'm also posting this on the LA mailing list, I thought
a good central location would be Santa Ana. Sorry, I know its
a drive for you guys, but please come if you can make it. The
date is tentatively Wednesday, June 18th, 7pm (or later if anyone
really wants to come and wants to push back the time). Oh yeah,
and the place is Santa Ana, at The Olde Ship
(www.theoldeship.com). I hope some of you can make it :-)

Well, Santa Ana is a bit far away (it's showing about an hour and
a half for me), but hey, meeting Perl Mongers from around the world
is part of what this is all about.  I'm fairly certain I'll show
up, just don't let us forget about it.

Hey folks,

Just a reminder, we have a meeting next Tuesday.  I'm currently
searching for locations that will be appropriate, but if I don't
find anything better plan on meeting at the same location as
last month, the food court at UTC.  If you have any better ideas
please let me know, otherwise I'll send out a reminder on Monday
and I'll see you next Tuesday evening.

At the meeting we can talk about finding a good place to meet,
meeting up with Tilly next month, projects and/or presentations
that we'd like to do, and anything else we can think of.

Perl Mongers,

Just the friendly reminder that there is a meeting this Tues evening.  I
was not able to secure an alternate location for this meeting, so it will
be at the same place it was last month, the food court at the UTC mall.
Look for the us by the Rubio's location.  I'll try to secure a location
away from the ice rink, close to the large set of windows.

Topics for this month include possible meeting locations for next month,
the Open Source/Perl Conference (in Portland), and whatever other topics
come to mind.

If you need directions or any other assistance, let me know.  Otherwise
I'll see everyone there about 7PM.
