从模块Drupal中将块内容解析为html

Question

I'am working on a module Drupal that needs an attribute value from another module, to get the block I found this :

$block = module_invoke('mymodule', 'block_view', 'myblock');

so I want to parse $block['content'] as html text and find my needed attribute. Is there a way to do that by simple method like find() or getElementById()

Any idea will be appreciated.

You can use following code as shown below:

<?php
$dom = new DOMDocument;
$dom->loadHTML($block['content']);
foreach($dom->getElementsByTagName('a') as $link) {
        # Show the <a href>
        echo $link->getAttribute('href');
        echo "<br />";
}
