extracting data between tags

KashKurcura

Hello:

I was wondering how a person would go about extracting data between data tags in a string? I think that preg_match_all would be the way to do it but I'm lost when it comes to that.

Thanks,

<?php
	$string="<em>this is the data</em>";
	$new=preg_replace("/<em>(.+)<\/em>/","\\1",$string);
	print $new;
?>

Is this what you need?

KashKurcura

ya something like that looks good but i get an error that says Unknown modifier '>'

also what if there are more tags within the string I would need to get them all?

Thanks!

Well, the code shouldnt look that way. This forum messed it up.
You have to add a backslash before /em

<?php
	$string="<em>this is the data</em>";
	$new=preg_replace("/<em>(.+)<(add a backslash here)/em>/","\\1",$string);
	print $new;
?>

strange ... coz it works fine here and I got "this is the data" returned.
Anyway, I've uploaded the file. Check it out.
If it still doesnt work ... no idea ...

ok that worked fine. thanks.

now if i add more information to the string iit gives me all the data and i would only like the information between the tags know what i mean?


$string="<em>this data</em> and <em>more data/em>";
$new=preg_replace("/<em>(.+)<\/em>/","\\1",$string);
print $new;

thanks again for your help!

Well, I think I know what you need.
Try to code a simple one just now and see what I've come up with.

You should get the following output:

$array[0][0]: this is the data
$array[0][1]: this also
$array[1][0]: this is the data
$array[1][1]: this also

As you may have guessed, the first element of the array is what you need.
HTH.
