[jira] Created: (XERCESJ-1082) compare of XML Schema datatypes (Xerces/JAXP)
compare of XML Schema datatypes (Xerces/JAXP)
---------------------------------------------
Key: XERCESJ-1082
URL: http://issues.apache.org/jira/browse/XERCESJ-1082
Project: Xerces2-J
Type: Bug
Components: XML Schema datatypes
Versions: 2.6.2
Reporter: Elena Litani
According to schema one should compare types that are in the same value space, therefore for example dateTime should not be comparable to date.
However, looking at the latest Xerces code, in particular XMLGregorianCalendarImpl and AbstractDateTimeDV (compareDates method), I did not see any check for actual type of schema datatypes being compared. This means that in some cases, for example, dateTime and time values could compare equal even though these should be "indeterminate". Sandy Gao noticed that same happens for String/anyURI comparison as well.
There are could be other types affected.

[jira] Resolved: (XERCESJ-1082) compare of XML Schema datatypes (Xerces/JAXP)

Michael Glavassevich resolved XERCESJ-1082:
-------------------------------------------
Resolution: Fixed
Hi Elena,
We are checking that two types have the same value space before checking if they're equal, however you won't find this code in the DVs. The check is being performed outside of the equals methods. When processing identity constraints, enumerations and value constraints we need to check that values are comparable before calling equals. This has been fixed for awhile for identity constraints and enumerations. Just put a fix in CVS yesterday for fixed values. That should cover all the cases now.
