Get html DOM tree by only basic builtin moudles

[Wesley]

Hi Laura,
  Sure, I got special requirement that just parse html file into DOM tree, by only general basic modules, and based on my DOM tree structure, draft an bitmap.

  So, could you give me an direction how to get the DOM tree?
Currently, I just think out to use something like stack, I mean, maybe read the file line by line, adding to a stack data structure(list for example), and, then, got the parent/child relation .etc

I don't know if what I said is easy to achieve, I am just trying.
Any better suggestions will be great appreciated.

Thanks.
Wesley
