This question already has an answer here:
I am trying to find all <a> tags and add a div around them. How do you change the RegEx to match <a><img></a> as well as <a>text</a>, or any tags within the <a> tag. I have:
<php
$a_pattern = '@<a\s*.*>.*(<.*>)?.*</a>@i';
$out = preg_replace_callback($a_pattern,"match_callback",$html);
function match_callback($matches)
{
var_dump($matches);
}
?>
</div>
Here is how you can do it with a built-in PHP DOM parser (using with a some fake HTML, but you will get the idea):
<?php
$doc = new DOMDocument('1.0', 'UTF-8');
$doc = DOMDocument::loadHTML('<body>
<a href="somewere"><img src="www.foo.com/example.gif" class="foo" alt="..."><br></a>
<a href="somewere again"><img src="www.bar.com/1.jpg" class="bar" alt="..."></a>
<a href="somewere again and back">Text</a>
</body>
', LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);
foreach ($doc->getElementsByTagName('a') as $a_node) {
$div = $a_node->ownerDocument->createElement('div');
$node = $a_node->parentNode->insertBefore($div, $a_node);
$node->appendChild($a_node);
}
echo $doc->saveHTML();
Output of the sample demo:
<body>
<div><a href="somewere"><img src="www.foo.com/example.gif" class="foo" alt="..."><br></a></div>
<div><a href="somewere%20again"><img src="www.bar.com/1.jpg" class="bar" alt="..."></a></div>
<div><a href="somewere%20again%20and%20back">Text</a></div>
</body>
You can also add attributes with the help of:
$node->setAttribute('class', 'title');
