I tried to run a java code, but failing to merge when second code have multiple item under Specification. Running okay when second have only single item even when first have multiple Items under specification.

Just for the information, your XML 1 and XML 2 are not valid XMLs. The element type "CompositePrice" must be terminated by the matching end-tag "". — John, Oct 21 '16 at 06:22
