Regex help - URGENT will pay!

I need to get from bellow html code this -> 110.234.71.142:8080

<td class="leftborder timestamp" rel="1342078386"><span class="updatets ">
18 secs</span></td>
         <td><span><style>
.wef6{display:none}
.N6zc{display:inline}
.ANrs{display:none}
.qQPY{display:inline}
.Cory{display:none}
.Jgqn{display:inline}
</style><span class="N6zc">110</span><span style="display:none">180</span><span class="ANrs">13</span><div style="display:none">176</div>.<span class="N6zc">234</span><span class="Cory">7</span>.<span style="display: inline">71</span><span class="wef6">63</span>.<span class="227">142</span></span></td>    
         <td>
8080</td>

Code (markup):

 

Why not do it using DOMDocument. Try following.

libxml_use_internal_errors(TRUE);
$dom = new DOMDocument();
$dom->loadHTML($code);
$xml = simplexml_import_dom($dom);
libxml_use_internal_errors(FALSE);

foreach($xml->xpath("//span") as $item){
    echo (string)$item . PHP_EOL;
}

PHP:

 

why not remove first all between <style></style> and then remove all <?>

you can use stripos to find </style>
php.net/strip_tags is also nice!

 

It looks like it has some false IP addresses too. Hmm can you show me where this code is being displayed, if possible? I may be able to assist you with something to parse it properly.

 

1)<span[\s]class="N6zc">([0-9]+).*?<span[\s]class="N6zc">([0-9]+).*?="display:[\s]inline">([0-9]+).*?</span>.<span[\s]class=.*?>([0-9]+)
2)([0-9]+)</td>
3)above are the two regex u can use to extract ip address(the first one ) and port number (the second one). then u can combine all the numbers.

 

ok it looks like you are doing some scraping there.

the problem I see ( not sure if I am right ) is that the css classes in the <style></style> tags are generated at random.

If you want a script that is handling random classes then look at this one.

might be a bit long but I commented every step and made it simple to understand.

<?php

// remove all line feeds    
$code = str_replace("\n",'',$code);        

// get the inline styles    
preg_match_all('|<style>(.*?)</style>|',$code,$arr);        

// get each style rule    
$parts = explode('.',$arr[1][0]);        

// ignore first one as empty    
unset($parts[0]);        

// delete style from $code    
$code = str_replace($arr[0][0],'',$code);        

// loop through all style rules    
foreach ($parts as $part) {                        

    // get what display the rule is            
    preg_match('|\{(display:.*)\}|',$part,$style);                        
    
    // get style class            
    $class = substr($part,0,4);                        

    // change class to style arrtibute on span elements            
    $code = str_replace('class="'.$class.'"','style="'.$style[1].'"',$code);                
}        

// check if there are style any classes left.    
preg_match_all('|span (class=".*?")|',$code,$arr);        

// ignore first one again.    
unset($arr[0]);

// loop through all left over classes    
foreach ($arr as $part) {            
 
    // change all left over classes it display:inline as there is no other rule defined for them.            
    $code = str_replace($part[1],'style="display:inline"',$code);                
}        

// get all inline spans         
preg_match_all('|<span style="display:\s*inline">(.*?)</span>|',$code,$arr);        

// join them with a .    
$ip = implode('.',$arr[1]);            

// get port number    
preg_match('|</td>             <td>([0-9]*)</td>|',$code,$arr);        

$port = $arr[1];

Hope this helps you.
