I could have a try, but before I would like to have an XHTML
command-line offline validator, is there something like that existing?

The critical first step is generating "well-formed XML".  I.e.
basic lexical/syntactic correctness, ignoring semantic constraints 
Most critical is no elements without closing tags.  For example <hr>
must be either <hr></hr> (valid XML, not valid HTML) or <hr/> (valid either).

Emiotting <hr/> has the advantage that it is correct for both XML and (modern) 

Once this is taken care of, we're a big step there.

Emacs nxml mode should be sufficient to check well-formedness.
