Is anyone using HaXml to validate XHTML Strict? The old 1.13.2 version has some bugs in how it handles attributes that stop me from using it. It handled the DTD parsing fine. The most-recent darcs version relies on a newer ByteString than I have, so it is not easy for me to test it. A recent (this year) darcs version failed to parse the DTD, yielding this error: validate: In a sequence: in content spec of ELEMENT decl: head When looking for a non-empty sequence with separators: In a sequence: Expected % but found | in file xhtml1 at line 252 col 50 when looking for a content particle when looking for a content particle This is the context: <!--================ Document Head =======================================--> <!ENTITY % head.misc "(script|style|meta|link|object)*"> <!-- content model is %head.misc; combined with a single title and an optional base element in any order --> <!ELEMENT head (%head.misc;, ((title, %head.misc;, (base, %head.misc;)?) | (base, %head.misc;, (title, %head.misc;))))> I appreciate any advice on this. cheers peter
