I have a simpleType declaration that looks like this:
<simpleType name="fooType"> <restriction base="token"> <pattern value="[a-zA-Z0-9_-]{4,24}"/> </restriction> </simpleType>
I want to accept values containing a minimum of 4 and a maximum of 24 characters in the set {a-z|A-Z|0-9|_|-}. Xerces-J 1.4.3 and 1.4.4 do not reject element values that contain more than 24 of the allowable characters. They do reject elements that contain less than 4 characters, though. This element gets rejected:
<foo>abc</foo> (error: "does not match regular expression facet '[a-zA-Z0-9_-]{4,24}'")
This one doesn't:
<foo>abc-123_AB1111111111111111111</foo>
Is the error in my pattern, or is Xerces-J doing something wrong? I can make this work by putting a maxLength facet inside the <restriction>, but I don't see why that should be necessary.
FWIW Xerces-J 2.0.0 beta 3 catches the error:
"[Error] test.xml:15:83: cvc-type.3.1.3: The value 'abc-123_AB1111111111111111111' of element 'foo' is not valid."

Hi Scott,
haven't tried out, but maybe Xerces-J 1.4.3 interprets the last dash as the dash of a range, like the ones before, and gets a bit confused. Perhaps try to quote it.
[a-zA-Z0-9_-]{4,24}
