On the SitePoint PHP blog today there's a new post from Craig Buckler for the WordPress users out there. The HTML that this popular blog/CMS tools spits out can sometimes be not-so-semantic. Craig shares a tip on cleaning up one aspect of it - the methods returning lists for menus or sitemaps.

love WordPress. I also love clean semantic HTML. Unfortunately, several of the standard WordPress theme functions return code that is a little untidy. For me, the primary culprits are wp_list_pages() and the newer wp_nav_menu(); both return an unordered list of page links.

He gives an example of a sample list generated by wp_nav_menu() that's full of badly formatted and unnecessary elements. To help fix the issue, he shares his regular expression-based call to strip out things like extra tabs, empty classes and all title attributes. Obviously you can customize this as you need, but it's a good start towards something that's a bit cleaner and up to code.
