URL to Match

Haris · 11-08-2007, 11:53 PM

I want to match this:

Code:

<i>-- http://www.<b>google</b>.<b>com</b>/ &nbsp; <a href="http://dmoz.org/Computers/Internet/Searching/Search_Engines/Google/">Computers: Internet: Searching: Search Engines: Google</a></i>

Through the domain part: http://www.<b>google</b>.<b>com</b>/ and get back the following part:

Code:

<a href="http://dmoz.org/Computers/Internet/Searching/Search_Engines/Google/">Computers: Internet: Searching: Search Engines: Google</a>

Currently using the following in my function:

Where $szSiteName == 'google'

PHP Code:


			
            $szURLToMatch = 'http:\/\/www.\<b\>'    .    $szSiteName    .    '\<\/b\>.\<b\>com\<\/b\>';
            preg_match("/\<i\>-- $szURLToMatch\/ &nbsp; (.*?) \<\/i\>/", $szGetContents, $aMatches);

But the array returns no match.

Basically I modified how the RegExp pattern is constructed. :)

Improved working version: http://talkphp.pastebin.com/d67d9837f

Apart from that, how do I make a word optional?

PHP Code:


			
        preg_match('/of (about)? \<b\>(.*?)\<\/b\>/',$szGetContents, $aMatches);

How do I make about optional? :confused:

As far as i can tell, you are already making "about" optional, if you add brackets around "of", followed by a ? it should have the same effect....

Code:

preg_match('/(of)?\s*?(about)?\s*?\<b\>(.*?)\<\/b\>/',$szGetContents, $aMatches);

I also added a non-greedy space matcher aswell, to take account for the spaces.

Of is not optional and it still doesn't work.

PHP Code:


			
preg_match('/ of (about)?\s*?<b\>(.*?)\<\/b\>/',$szGetContents, $aMatches);

Where $this->szURL == www.lost-series.com

Edit:

This works:

PHP Code:


			
preg_match('/ of( about)? <b\>(.*?)\<\/b\>/',$szGetContents, $aMatches);

Meaning, the space that comes with the "about" is also optional (which would make sense not to have two spaces). Sorry i couldn't of been of more help :)
