Hi, I was wondering how you strip the contents of a string uptil the first occurance of <a and also how to strip a string to the last occurance of </a>

ie

$string = '<body>
<a href="test.htm">test</a>
<a href="text2.htm">test2</a>
</body>';

will return:

$string = '<a href="test.htm">test</a>
<a href="text2.htm">test2</a>';

Appreciate it if someone could help. Thanks

Hi, I need to include the content in between the <a> tags that's why regular expressions is the way to go. Cheers anywayz

did you *try* using strip_tags? this does *exactly* what you're asking:
Code: 
$string = '<body><a href="test.htm">test</a><a href="text2.htm">test2</a></body>';

//  $foo will contain the string:
//  '<a href="test.htm">test</a><a href="text2.htm">test2</a>'
$foo = strip_tags($string, "<a>");

Hi, when I ran it I got testtest2 but I want:

$string = '<body>
<a href="test.htm">test</a>
<a href="text2.htm">test2</a>
</body>';

to return:

$string = '<a href="test.htm">test</a>
<a href="text2.htm">test2</a>';

Odd, the example worked for me. I copied and pasted it into a file, added some script tags, worked perfect...?

if you echo the string '<a href="test.htm">test</a>
<a href="text2.htm">test2</a>' to a browser, of course it will show up as testtest2 because the browser is interpreting the HTML!

this doesn't change the fact that the string actually contains the text: <a href="test.htm">test</a>
<a href="text2.htm">test2</a>

try echoing inside a <textarea> to see...

It still strips all the html out in between though so it isn't gonna work. Any other idea?

here's two ways:
Code: 
$str = <<<END
<p>foo</p>
	<a href="page.html">page</a>
<ul>
	<li>1</li>
	<li>2</li>
</ul>
<div>div</div>
<span><a href="two.html">two</a></span>
END;

	//  harvest only links:
	$matches = null;
	preg_match_all('/<a href="[^"]*">[^<]*<\/a>/', $str, $matches);
	
	
	//  extract from first <a to last </a>:
	$start = stripos($str, "<a");
	$end = strripos($str, "</a>") + 4;
	$len = $end - $start;
	$new_str = substr($str, $start, $len);
