Finding a href value with Regex

Question

I have a document with the following code inside

<link rel="next" type="application/atom+xml" href="https://xxxxxxxx.com?page=2"/>

Is there some regex that will look for a link tag with the rel of 'next' and get me the href value? This is far beyond my regex skills.

Thanks in advance

Answer 1

This type parsing shouldn't really be done from regex as unexpected nature of HTML can break the regex anytime.

Consider this DOM based code for this job:

$dom = new DOMDocument; 
$dom->loadXML(
  '<link rel="next" type="application/atom+xml" href="https://xxxxxxxx.com?page=2"/>'); 
$xpath = new DOMXPath($dom); 
$nodelist = $xpath->query("//link[contains(@rel, 'next')]");
for($i=0; $i < $nodelist->length; $i++) {
    $node = $nodelist->item($i);
    echo $node->getAttribute('href') . "\n";
}

OUTPUT:

https://xxxxxxxx.com?page=2

尝试这个

href=[\'"]?([^\'" >]+)
