Historical and debugging.

They essentially just hide private members of the various structures.

Unless new functions have been added recently, there are just a few
functions that essentially pretty print nodes ala tidyNodeGetText;
they would give you text in some way, but you'd have e.g. special
characters escaped. Internally, the text is stored in the lexbuf and
individual node types point into the buffer. A simple even if in-
efficient way to get the text is to let Tidy convert the document to
XHTML and use an XML parser for further processing.
