DOM manipulation inside the webmaster

Question

I know that workers cannot manipulate a document directly, but what about DOM API methods? Where did they go?!

For example, if I make a request that receives an HTML fragment, then what should I do if I just need to parse it to extract some data from a particular node ?!

There is absolutely no way to work with a virtual DOM for web workers ?!
