Thanks Gilbert for quick response. The first solution would be suitable for my current issue & it worked out.
Currently i am using Ant1.6.5 and in Ant Manual [for 1.6.5] for FileSets i don't see "id" attribute in the Attribute || Description || Required table. Can you please check if this information is updated in ant1.7 manual?
