[PHP] Extracting text

[w1ww]

Hello,

Can you guys help me a little bit with this (PHP).

Imagine that I've this html code:

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="437" height="288" id="viddler_aae0f0d6"><param name="movie" value="http://www.viddler.com/player/aae0f0d6/" /><param name="allowScriptAccess" value="always" /><param name="allowFullScreen" value="true" /><embed src="http://www.viddler.com/player/aae0f0d6/" width="437" height="288" type="application/x-shockwave-flash" allowScriptAccess="always" allowFullScreen="true" name="viddler_aae0f0d6" ></embed></object>

I want to extract the id field id="viddler_aae0f0d6".

How can I do this knowing that every time the id it's going to be different?

So basically to extract "viddler_aae0f0d6" from this code.

Anyone has ideas?

Regards!

$htmlcode='<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="437" height="288" id="viddler_aae0f0d6"><param name="movie" value="http://www.viddler.com/player/aae0f0d6/" /><param name="allowScriptAccess" value="always" /><param name="allowFullScreen" value="true" /><embed src="http://www.viddler.com/player/aae0f0d6/" width="437" height="288" type="application/x-shockwave-flash" allowScriptAccess="always" allowFullScreen="true" name="viddler_aae0f0d6" ></embed></object>';
$theid = preg_replace('/(.*) id=\"(.*)\"(.*)/Usi','$2=_=',$htmlcode);
list($theid,$dump)=explode("=_=",$theid);

echo $theid;

$theid, contains the new id

$id = substr($text, strpos($text, ' id="') + 5, 16);

Assumes constant length id, (I checked other videos on the site, they all have a 16 id too, so not a problem.)

I would use preg_match.

http://uk2.php.net/preg_match

<?php

$htmlcode='<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="437" height="288" id="viddler_aae0f0d6"><param name="movie" value="http://www.viddler.com/player/aae0f0d6/" /><param name="allowScriptAccess" value="always" /><param name="allowFullScreen" value="true" /><embed src="http://www.viddler.com/player/aae0f0d6/" width="437" height="288" type="application/x-shockwave-flash" allowScriptAccess="always" allowFullScreen="true" name="viddler_aae0f0d6" ></embed></object>';
$count = preg_match('/\sid\s*=\s*"(.*?)"/',$htmlcode, $matches);
if ($count)
{
    $theid = $matches[1];
    echo $theid;
}
else
{
    echo "ID not found\n";
}

?>

Unlinke the previous solutions, this will also match with whitespaces before/after the equals sign or line breaks before the id tag. If you know what characters to expect in the id value, you could improve the regexp. Currently it will match any characters within the quotes.
