couple of useful snippets from an article I found at Perl.com

(Perl) scraper

For a while I used this to scrape weather.com. Then they changed their HTML and my script broke.

(Perl) id3.pl

Tue, 03 Jul 2007 22:40:18 GMT

This script takes a list of directories as its argument. For mp3s that don't have any id3 information, guess the name of the artist and track based on the filename and use the MP3-Info module to insert that guess into the file as id3v1 tags.

(Perl) Remove duplicate lines from a text file

Tue, 03 Jul 2007 22:06:34 GMT

Sometimes I get a big list of things, and some of the things occur multiple times in the same list. A good example is a newline-delimited list of files: the same file path might be listed 4 or 5 times. So this script removes those kinds of duplicate lines. Found at Google Answers.

(Perl) Show JPEGs in this directory all on one page

Tue, 03 Jul 2007 21:57:11 GMT

Dumps a list of image names into an HTML document, wrapped in centered IMG tags. Features the CENTER tag for added historical value.

(Perl) show JPEGs in this directory in a simple HTML gallery

Tue, 03 Jul 2007 21:53:26 GMT

Creates an HTML page with the first image in the directory in the center. Forward and Back buttons scroll through all the images in the directory in order. This is how I lived before Firefox ~.^

(Perl) Examine CSS selectors in JSP files and report on whether they match some patterns

Tue, 03 Jul 2007 21:27:59 GMT

Processe a directory of JSP source files, looks for regex matches, and reports on the number and location of matches. For detecting deprecated attributes in XHTML. Uses Mail::Outlook to send an email. Requires you to click "ok" each time a notification is sent, but gets around firewalls.

(Emacs Lisp) Emacs regular expression to match curly brackets without breaks before them

Fri, 01 Jun 2007 12:44:29 GMT

A variant of this code is in use on the My Organizer app at http://collegeboard.com/student/index.html?student

(JavaScript) Use a regex on a multiline string

Fri, 30 Mar 2007 09:14:35 GMT

Apply string.replace() where string has line breaks, and .replace() only happens for the first line of the string! The fix is to turn newlines into unicode characters, run the regex, then turn the unicode back into newlines. From comp.lang.javascript (thanks, Evertjan):
