regex help

Could someone help me out with a regular expression?

I need to be able to search a text field and grab every instance of a
string that falls between <tag class="name"> and </tag>.

We can assume that the tags will always be written properly.


So if the following is my text field: "They streamed across the Clemente
Bridge, docked along the <tag class="name">Al legheny River</tag>, strolled
from the North Side and biked down the trail to watch their Pirates. <br/>
They filled <tag class="name">PN C Park</tag> to the last sliver of
standing-room space on the rotunda, <tag class="name">37 ,259</a> strong.
<br/> And they came in full throat, chanting and cheering from the outset."

....I'd need the code to return, probably an array, like this:
$array[0] = Allegheny River
$array[1] = PNC Park
$array[2] = 37,259


I just can't get it. Any suggestions?

So why did you make an error in your example? :)

[string][color=blue]

Tell us where you are running into problems. It's really simple if:
-you know the correct function
-you know your regexpes.

Do you want to learn how to do it or do you just want the answer of how
to get an array like:

Array
(
[0] => Array
(
[0] => <tag class="name">Al legheny River</tag>
[1] => <tag class="name">PN C Park</tag>
[2] => <tag class="name">37 ,259</tag>
)

[1] => Array
(
[0] => Allegheny River
[1] => PNC Park
[2] => 37,259
)
)

If you want to learn see
http://nl2.php.net/manual/en/functio...-match-all.php (the examples
contain samples that match your question closely) and
http://nl2.php.net/manual/en/referen...ern.syntax.php (study
greedy vs. non greedy)

The spoiler is below:






















preg_match_all( '/<tag class="name">(. *?)<\/tag>/',$str,$matches );
