Parse html - CURL and regular expression

Question

How to get text: "Text example max" from:

<td valign="top" align="left">

    <a href="/server?tree=xabaf"
    class="normal"> Text example max </a>

</td>

using regular expression?

include('simple_html_dom.php');
$ch = curl_init('http://www.site.com?id=325235');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$sss = curl_exec($ch);
curl_close($ch);

preg_match_all("#class="normal"?</a>$#", $sss, $arr);

So why do you even want to do this with a regular expression? Why not use any of the other available techniques to parse HTML? — Konrad Neuwirth

Apart from the fact that you shouldn't use regex to parse HTML, you need to show what you have tried doing before expecting others to help. This is not a code generation site. — Aleks G

Solution using REGEX

$text = "<a href='/server?tree=xabaf' class='normal'> Text example max </a>
";
$regex_pattern = "/<a href=\"?\'?(.*)\"?\'?>(.*)<\/a>/";
preg_match_all($regex_pattern,$text,$matches);

PHP's DOM

$text = "<a href='/server?tree=xabaf' class='normal'> Text example max </a>";
$dom = new DOMDocument;
$dom->loadHTML($text);
$links = $dom->getElementsByTagName('a');
foreach ($links as $link){
    echo $link->textContent;
}

Use DOM and not regex.

Since there's no other text, applying strip_tags() is enough.

$str ='<td valign="top" align="left">

    <a href="/server?tree=xabaf"
    class="normal"> Text example max </a>

</td>';

$str = trim(strip_tags($str));

you can try this...

include('simple_html_dom.php');

$url = 'http://www.site.com?id=325235';

$curl = curl_init(); 
curl_setopt($curl, CURLOPT_URL, $url);  
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);  
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10);  
$str = curl_exec($curl);  
curl_close($curl);

$html = str_get_html($str);

$content = $html->find('div[class=normal]');
echo $content->innertext;
