XMLBeans enforcement of xs:pattern in simple type?

2010-12-14 Thread Chris Hopkins 
Hi all –



I’m working with a schema that has the following simple type:



xs:simpleType name=DateTimeGroupType

xs:annotation

xs:documentationA date
time group always in Zulu time./xs:documentation

/xs:annotation

xs:restriction base=xs:dateTime

  xs:pattern
value=^(3[0-1]|2[0-9]|1[0-9]|0[1-9])(0[0-9]|1[0-9]|2[0-3])([0-5][0-9])\sZ\s(Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)\s[0-9]{2}$/

/xs:restriction

/xs:simpleType



I thought, perhaps naively, that specifying a pattern would force the
XMLBeans generated classes to validate against that pattern including
producing a String representation conforming to that pattern when I call
getStringValue(). This is not the result that I’m getting but perhaps I’m
doing something wrong with the definition.



Does anyone have any insight or experience doing the same thing?



Thanks,

Chris

Chris,

 

If you check the XMLSchema spec: 

http://www.w3.org/TR/xmlschema-2/#dateTime 3.2.7.1 explains the lexical 
representation of datetime. This '-'?  '-' mm '-' dd 'T' hh ':' mm ':' ss 
('.' s+)? (zz)? is the production that you can restrict in a derived 
restriction. If you don't restrict using that production no instance will match 
it, so you'll have a type with no valid values.

 

As for XMLBeans serializing according to a pattern, it will as long as the 
instance is a valid instance of the defined type.

 

Also check the definition of pattern: 
http://www.w3.org/TR/xmlschema-2/#dt-pattern

 

I hope this helps,

Cezar

Ah...right...I forgot about that aspect of restrictions. Thanks for the
clarification!
