Finding all javascript onclick used like <a> tag

PHP
1

Hey guys,

godaddy.com uses onclick for many different elements instead of the <a> tag with href. They use the onclick attribute in <a> tags, <li> tags, and some other tags, to send javascript a link to open on the page. How can I check for this with PHP, if any site uses javascript to navigate, instead of the a href?

regExp for onclick within an <a> tag.
Or try DOMDocument
