Extract attribute value with Regular Expression?

[ScottDC]

Hi

My PHP is a little rusty, as are my regular expressions.

I have a html string held in a variable in php:

Code: Select all

<img src="blah.jpg" alt="what I want" border="0"/>

What is the simplest method to extract the value of the alt attribute?

Thanks

This might work:

PHP: Select all

<?php 
$img='<img src="blah.jpg" alt="what I want" border="0"/>';
$alt=preg_replace('/.*alt="(.*!")".*/U','$1',$img);
echo $alt;
?>

Got it to work after a couple of changes, thanks.

Code: Select all

<?php 
$img='<img src="blah.jpg" alt="what I want" border="0"/>';
$alt=preg_replace('/.*alt="([^"]*)"[^.]*/','$1',$img);
echo $alt;
?>
