If I validate the file error10.xhtml, I get the following errors:
file:///error10.xhtml:13,71: Datatype error: Type:InvalidDatatypeValueException, Message:'-' is not a valid character range; use '\-' instead.
file:///error10.xhtml:13,71: Datatype error: Type:InvalidDatatypeValueException, Message:'-' is not a valid character range; use '\-' instead.
file:///error10.xhtml:15,38: Datatype error: Type:InvalidDatatypeValueException, Message:'-' is not a valid character range; use '\-' instead.
file:///error10.xhtml:16,38: Datatype error: Type:InvalidDatatypeValueException, Message:'-' is not a valid character range; use '\-' instead.
file:///error10.xhtml:17,36: Datatype error: Type:InvalidDatatypeValueException, Message:'-' is not a valid character range; use '\-' instead.

The XML document error10.xhtml is NOT valid (5 errors)

The file http://www.w3.org/2002/08/xhtml/xhtml1-transitional.xsd validates without errors. What's wrong with my file?

thank you, Hans-Peter Küchler

Hi Hans,

It seems like the attachment didn't make it.
Could you try again?

Thank You
Ivan

I was able to retrieve the attachment.
The problem is actually in the XML Schema; XercesJ provides good information about that error:

http://www.w3.org/2002/08/xhtml/xhtml1-transitional.xsd:230,38: (Error) InvalidRegex: Pattern value '[-+]?(\d+|\d+(\.\d+)?%)' is not a valid regular expression: ''-' is an invalid character range. Write '\-'.'.
http://www.w3.org/2002/08/xhtml/xhtml1-transitional.xsd:241,38: (Error) InvalidRegex: Pattern value '[-+]?(\d+|\d+(\.\d+)?%)|[1-9]?(\d+)?\*' is not a valid regular expression: ''-' is an invalid character range. Write '\-'.'.
http://www.w3.org/2002/08/xhtml/xhtml1-transitional.xsd:276,38: (Error) InvalidRegex: Pattern value '[-+]?(\d+|\d+(\.\d+)?%)(,\s*[-+]?(\d+|\d+(\.\d+)?%))*' is not a valid regular expression: ''-' is an invalid character range. Write '\-'.'.

If you escape the '-' used in the character lists, as '\-', then your XHTML validates fine.

Hope this helps,
Minollo

Hi Minollo,
after reading http://www.w3.org/TR/xmlschema-2/#regexs, I think that the - should only be escaped if it is used to form a 'atom'. In this case the - is a metacharacter. But used in a character class, the - isn't an atom. Instead, the complete character class itself is an atom. http://www.w3.org/TR/xmlschema-2/#dt-charrange says "The - character is a valid character range only at the beginning or end of a ·positive character group·." The - used in the schema is the beginning of a positive character group [-+] containing - or +.

Btw. I can't change the schema easily because it's referenced by http://www.w3.org/TR/xhtml1-schema/Overview.html;-)

regards, Hans-Peter

Hi Hans-Peter,
you are right, there is an error in both Xerces-C and Xerces-J validators; as a partial excuse for them is the fact that the presence of the "-" character in the regular expression grammar was ambiguos, and an errata (E2-18, http://www.w3.org/2001/05/xmlschema-errata.html#e2-18) prohibited altogether. After that, another errata (E2-67, http://www.w3.org/2001/05/xmlschema-errata.html#e2-67) reversed the change and added the clarification note that you are quoting. It looks like the Xerces team overlooked the latter.

Thanks for reporting this,
Alberto
