I agree with your "to test it fully, we need extra dependencies",
but my point is that it does not have to be a full "HTML-validating,
picking the expected attribute via XPATH matching" kind of test if
what we want is only to add a new test to protect this particular
fix from future breakages.

For example, I think it is sufficient to grep for 'href="...%xx%xx"'
in the output after preparing a sample tree with one entry to show.
The expected substring either exists (in which case we got it
right), or it doesn't (in which case we are showing garbage).  Of
course that depends on the assumption that its output is not too
heavily contaminated with volatile parts outside our control, as I
already mentioned in the message you are responding to.

But it all depends on "if" we wanted to add a new test ;-)
