how to replace certain tag from first and last ??

[PHPycho]

Hello forums..
Can anybody give a hint for how to replace the first <ul> and last </ul> tag from the string $string:
$string = '<ul>
<li></li>
<li>
<ul>
<li>
</li>
<li></li>
</ul>
</li>
<li></li>
</ul>';

Thanks in advance to all of you.

To replace <ul> with <ba> use this:


$string = '<ul>
<li></li>
<li>
<ul>
<li>
</li>
<li></li>
</ul>
</li>
<li></li>
</ul>';

$string = ereg_replace('<ul>','<ba>',$string);
$string = ereg_replace('</ul>','</ba>',$string);

echo $string; // Returns: <ba> ... </ba>

Ah, I'm sorry, I misunderstood your question! :)

To replace the first <ul> and last </ul> ... I'm not sure :)

Not sure how stable this is but it will do the trick in most cases:

$string = '<ul>
<li></li>
<li>
<ul>
<li>
</li>
<li></li>
</ul>
</li>
<li></li>
</ul>';

$newString = substr($string, 4, strlen($string)-9);
