Substitution under the node

Sorry for asking, however I am a bit lost here.

I need to parse the DOM tree, and when I encounter specific Attribute, use the information to substitute all occurrences of specific symbols within the scope of that node: could be <body> or some low-level <div>

Is there an example which I can use?

Or - what docco should I read?
