Hi,

 this is how I currently do the debugging of html-export (there may be
more elegant ways, but it works well for me):

- Copy (defun org-export-as ...) from ox.el into a local elisp buffer
  of your liking (any buffer with the name .el should do).

- In that function add the line (setq info-debug info) just after the
  comment lines (Lines 2997/2998):

  ;; Eventually transcode TREE.  Wrap the resulting string into
  ;; a template.
  (setq info-debug info)

- Evaluate the new definition of org-export-as and run the export from
  your org file once.

Now you can access the complete parse tree with

(plist-get info-debug :parse-tree)

(make sure just to use a small document, otherwise the output might be
pretty nasty as the parents of all elements are recursively fully
contained in the parse tree).

You can extract all links of your document with:

(setq all-links
  (org-element-map (plist-get info-debug :parse-tree) 'link 'identity))

And you can check the output string of html with this:

(org-html-link (nth 0 all-links) "" info-debug)

You can then check what you have to do to make org-html-link output
the desired string, or redefine org-html-link to do what you need and
later make a derived backend from the html backend replacing the
org-html-link function or simply load the new definition of
org-html-link using a mechanism like #+SETUPFILE: in your header.

HTH,
Orm
