The use case for Regular Expressions are clear - I want to detect if a string is something that is probably a date in a particular format etc. The equivalent for a DOM is not clear - if your argument is purely efficiency - which could be a good one certainly - then you still need use cases that justify the underlying technique - I want a nodelist of all things in a document which match a particular CSS class is not an obvious one to me - every use case I can see for it is better to simply change the CSS class itself.
