I'd like to add a little there. Although the Mono project is great, it
is always left a step behind, because Microsoft has a tendency to
release newer features of .Net that the Mono developers have to play
catch-up with.
Like Paul mentioned, it's probably not safe to let yourself be tied in
to a closed format, even if it has open parts. One only has to look back
a few years to find more examples of companies losing data because it
was locked into an old format, or being stuck with old and obsolete
versions of software because the company that makes it stopped writing
it, or went bust. This sort of thing doesn't really happen with OSS,
because there is always a community ready to take up the projects.

Re: [PHP] Little Parsing help...
Don,
How far along are you? To get started something like this may work for
you...
preg_match_all('/[A-G]{1}#?/', $line, $matches);
That SHOULD return each note of the line (you can retrieve them via the
$matches array), given that there are no other upper-case characters that
are not notes. Also this assumes that $line has exactly one line in it. :)
If you get that working, perhaps you can setup something using the
preg_replace method?
http://php.net/manual/en/function.preg-replace.php
Another option is to use the str_replace function.
http://us3.php.net/manual/en/function.str-replace.php
I gotta run (else I would type some more) but let me know if you want any
advice on using those!
Chris.

[PHP] Scraping Multiple sites
I'm currently stuck on a little problem. I'm using cURL in conjunction with DOMDocument and Xpath to scrape data from a couple of websites. Please note that is only for personal and educational purposes. Right now I have 5 independent scripts (that traverse through 5 websites) that run via a cron tab every 12 hours. However, as you may have guessed this is a scalability nightmare. If my list of websites to scrape grows I have to create another independent script and run it via cron. My knowledge of OOP is fairly basic as I have just gotten started with it. However, could anyone perhaps suggest a design pattern that would suit my needs? My solution would be to create an abstract class for the web crawler and then simply extend it per website I add on. However, as I said my experience with OOP is almost non-existant therefore I have no idea how this would scale. I want this 'crawler' to be one application which can run via one cron rather than having n amount of scripts for each websites and having to manually create a cron each time. Or does anyone have any experience with this sort thing and could maybe offer some advice? I'm not limited to using PHP either, however due to hosting constraints Python would most likely be my only other alternative. Any help would be appreciated.

I would try to avoid having any code specific to a site, otherwise scaling your application to support even a hundred sites would involve overlapping hundreds of points of functionality and be a logistical nightmare. Unless you're simply wanting to do this for educational reasons... My suggestion would be to attempt to create an application that can craw all the sites, without specifics for each one. You could fire it with a single cron job, and give it a list of the urls you want it to hit. It can crawl one url, record the findings, move to the next, repeat. Chris.
