Modifying HTML Dynamically

[geckofuel]

Perhpas a better title would have been "Reverse Mod-Rewrite"

How would one go about modifying every occurrence of a particular string in HTML dynamically?

Here's what I'm interested in doing.

Say that you've got a bunch of links like the following:

/cgi-bin/cgifile.cgi?file=2&position=7

And you'd like for each occurrence of these links to be modified to read something like this:

/cgi-bin/cgifile/2/7

Is there a way to modify HTML on the fly so that every occurrence of the first type of a link is modified into the format of the second type of link?

If a file has a whole series of the first type of links, is there anyway to filter the serving process so that the second format is substituted for the first?

You could write an Apache [httpd.apache.org] module that postprocesses your output. This will be fast but you need to know about the Apache [httpd.apache.org] API. Or have a look at Bag-O-Tricks for PHP II - some code snippets that should be helpful for all in creating dynamic sites - Getting rid of those query strings [webmasterworld.com] for an explanation on how to do it using PHP [php.net].

Hey andreas, if that thread was an affiliate program you could retire today..all roads lead to.....bag of tricks ;) jk of course....

gecko, is the HTML already on the page, maybe pulled from a db...? If it's in a variable it might be easy-ish to use a little REGEX when needed to strip the query strings you want removed.

Not sure if the REGEX is already in that thread andreas posted, if it isnt, its nearby :)

>>all roads lead to.....bag of tricks ;)

Amazing, isnīt it. I have been posting these links quite often lately. Now either those bags are already quite full with nice little scripts or people keep asking the same questions ;).

>>REGEX is already in that thread andreas posted

Yes it is. ;)

BTW good luck with your bio-informatics plans, bol. Are you on your way to become the next Lincoln Stein ;)?
