input message parser (regex)

« on: November 01, 2007, 04:01:43 PM »

Hey all,

Im trying to make a regular expressions that can handle all the bot commands.
well maybe this is not needed but, how do I do it otherwise?

I got it to grab multiply items from one command.

the code look like this:

Code:

<?php

/**
*
*
* @version $Id$
* @copyright 2007
*/
$input = 'loot add <a href="itemref://206204/206204/1">Twilight\'s Murder</a> <a href="itemref://223322/206204/1">I am gimp</a> test';
preg_match_all('/<a href="([^"]*)">([^<]*)<\/a>/im', $input, $matches, PREG_SET_ORDER);
print_r($matches);
?>

and it result in this:

Code:

Array
(
[0] => Array
(
[0] => <a href="itemref://206204/206204/1">Twilight's Murder</a>
[1] => itemref://206204/206204/1
[2] => Twilight's Murder
)

[1] => Array
(
[0] => <a href="itemref://223322/206204/1">I am gimp</a>
[1] => itemref://223322/206204/1
[2] => I am gimp
)

)

but I still lack to be able to grab loot add and test

I tryed to put in (\w*) thro it give all kind of diffrent output.

The output im looking for is this:

Code:

Array
(
[0] => Array
(
[0] => loot
)
[1] => Array
(
[0] => add
)
[2] => Array
(
[0] => <a href="itemref://206204/206204/1">Twilight's Murder</a>
[1] => itemref://206204/206204/1
[2] => Twilight's Murder
)

[3] => Array
(
[0] => <a href="itemref://223322/206204/1">I am gimp</a>
[1] => itemref://223322/206204/1
[2] => I am gimp
)
[4] => Array
(
[0] => test
)
)

this parser should be working with all count of pre word/numbers and after word/numbers

I do not understand the question.

The only problem that can't be solved by adding another wrapper is having too many wrappers.

The regular expression returns exactly what it's supposed to. Maybe you'll have to use more then one regular expression, or a more general one, or split up the input before preg_match(). I doubt that it's possible to match your wished output format exactly though.

ok how do I split it up?

I just want to be able to check against the words and items.

I do not understand the question.

I want to put the input string

Code:

"loot add <a href="itemref://206204/206204/1">Twilight\'s Murder</a> <a href="itemref://223322/206204/1">I am gimp</a> test"

into a array with each section in it.
as in

loot, add, first item, 2nd item, test.

So I can if ($output[4] == "test") echo "this is what I want";
and so on

I found the solution that I can use.

Code:

<pre>
<?php

/**
*
*
* @version $Id$
* @copyright 2007
*/

$str = 'Søg på <a href="http://www.google.com/">google</a> <a href="http://www.google.com/">google</a> for at finde det du mangler';
$chars = preg_split('/(<a.*<\/a>)/im', $str, -1, PREG_SPLIT_DELIM_CAPTURE);
print_r($chars);
?>
</pre>

that give this result

Code:

<pre>
Array
(
[0] => Søg på
[1] => <a href="http://www.google.com/">google</a> <a href="http://www.google.com/">google</a>
[2] => for at finde det du mangler
)
</pre>

from this I know that chars[0] is all before the items, chars[1] is all items posted and chars[2] is everything after items
