During the last year I had made severe modifications to FPC XML
units. The current version is fully compliant with W3C test suite,
supports UTF-8 and UTF-16 encodings, XML 1.1, entity processing and DTD
validation.
This stuff (namely DOM.pp, XMLRead.pp, XMLWrite.pp, XMLUtils.pp and
UriParser.pp from
packages/base/netdb) also compile with Delphi 7 without any changes.
I also successfully compiled Lazarus locally using modified FPC units, and it
proves working. I did not release this patch to public for several
reasons:
a) The patch isn't complete - it just changes used units while all
string variables outside those units remain ansi.
b) There are known issues with WideStrings on Windows. Although
at a glance everything seem not to be touched by these issues, I cannot
be sure it really isn't.
c) Performance issues - the Widestring-based reader is somewhat slower
than current AnsiString-based.
Nevertheless, if anyone is interested in incorporating these changes
into Lazarus, I will send the patch.
Best regards,
Sergei Gorelkin
