Help with function

TonyB

I'm using the snoopy class to return a list of links from a webpage. I want that list to be everything between "<a href=" and "</a>. But the class only returns the link and not the title. I've tried everything I can think of in the function, but can't get it modified to work.

Here's the function

/*======================================================================*\
	Function:	_striplinks
	Purpose:	strip the hyperlinks from an html document
	Input:		$document	document to strip.
	Output:		$match		an array of the links
\*======================================================================*/

function _striplinks($document)
{	
	preg_match_all("'<a\s+href\s*=\s* 			# find <a href=
					([\"\'])?					# find single or double quote
					(?(1) (.*?)\\1 | ([^\s\>]+))		# if quote found, match up to next matching
												# quote, otherwise match up to next space
					'isx",$document,$links);


	// catenate the non-empty matches from the conditional subpattern

	while(list($key,$val) = each($links[2]))
	{
		if(!empty($val))
			$match[] = $val;
	}				

	while(list($key,$val) = each($links[3]))
	{
		if(!empty($val))
			$match[] = $val;
	}		

	// return the links
	return $match;
}

So how can I change it to return the full link and title?

Anyone have any ideas?

You can return an array from a function by doing:

return $match = array ($match, $document, $link);

That isn't my problem with this one.


    preg_match_all("'<as+hrefs*=s*             # find <a href=
                    ([\"'])?                    # find single or double quote
                    (?(1) (.*?)\1 | ([^s>]+))        # if quote found, match up to next matching
                                                # quote, otherwise match up to next space
                    'isx",$document,$links);

in a sample link

<a href="http://www.somesite.com/somepage.html">Click Here For More</a>

This part of the code stops the strippign with the second " marks and therefore returns on the url of the link:

http://www.somesite.com/somepage.html

I know the code can be changed to return the url and the link text, it is just beyond my ability to change it.

I'd actually like to change the code to return to the url and link title
