have been thinking if it is possible to make a compiler time XML parser.

The similar function to Eric lib would be to have the lib read the DTD
file at compiler time and make a parser which could validate XML files.

Another idea is to make a library which make it possible 
to write XML pages in a way so that they always is valid.

Interesting concept.  While I cringe at the mere thought of writing a DTD parser
(I shyed away from this when I wrote my XML parser some time ago), I can
certainly see the value in this.  I say: go for it!

The only major problems you're going to run into is with the upper limit on
mangled D symbol name lengths.  This pretty much goes for any template that
accepts a const char[] value as an argument: it forces a hard limitation on the
size of the data set you can process.  The regex engine has the regex spec on
its side, as most expressions are usually very brief.

Another idea is to make a library which make it possible 
to write XML pages in a way so that they always is valid.

Sort of like a DTD aware, validating, writable DOM?  Sweet.

One request if I may: please adopt a strategy like I did with regex, where you
have a separate compile-time and runtime portions to the DTD lib if you can.
That way, people can use the runtime portion if they see the need (not to
mention the runtime portion will be testable separate from the compile-time
portion that merely leverages it).
