[SOLVED] matching <h3 class=r><a href="[url]"

[daydreamer]

I am trying to match <h3 class=r><a href="" and save just the URL's into an array.

 

This is what I have so far:

 

<?php
$pattern='/class=r><a[\s]href="[A-Z0-9a-z.-]+"/';
preg_match_all($pattern, $data, $matches);
print_r($matches);
?>

 

What needs to be changed?

 

Thanks.

Well most URL's have slashes and colons

so update the pattern to

$pattern='%class=r><a\s+href="([/:A-Z0-9.-]+)"%i';

 

or try

preg_match_all('/class=r><a\s+href="([^"]*)"/i', $data, $matches);
$result = $result[0];

Ok thanks, the last one works perfectly.

Alternatively, you could also resort to DOM/XPath for this sort of thing:

 

Example:

$html = <<<EOF
<h3 class=r><a href="[url=http://www.whatever.com]www.whatever.com[/url]">Link</a>
<table><td><tr>blah</tr></td></table>
<h3 class=r><a href="[url=http://www.whatever2.org/somefolder/index.php]www.whatever2.org/somefolder/index.php[/url]">Link 2</a>
EOF;

$dom = new DOMDocument;
@$dom->loadHTML($html); // change loadHTML to loadHTMLFile, and replace $html with the real url encased in quotes
$xpath = new DOMXPath($dom);
$aTag = $xpath->query('//h3[@class="r"]/a');
foreach ($aTag as $val) {
    $arr[] = $val->getAttribute('href');
}

echo '<pre>'.print_r($arr, true);
