Desired output
Need country code to be displayed once per fund11111 and fund22222

<FundsXML> <Funds> <Fund> <Name>Fund11111 </Name> <FundFacts> <KeyFacts> <Registration> <Country>AT</Country> </Registration> <Registration> <Country>BE</Country> </Registration> </KeyFacts> </FundFacts> <Name>Fund22222 </Name> <FundFacts> <KeyFacts> <Registration> <Country>AE</Country> </Registration> <Registration> <Country>AT</Country> </Registration> <Registration> <Country>BE</Country> </Registration> <Registration> <Country>PT</Country> </Registration> </KeyFacts> </FundFacts> </Fund> </Funds> </FundsXML>
The code is displayed singlecountry record for first fund only and removing country value records which are present in Fund22222

Output displayed by above XSLT
==============================
<FundsXML> <Funds> <Fund> <Name>Fund11111 </Name> <FundFacts> <KeyFacts> <Registration> <Country>AT</Country> </Registration> <Registration> <Country>BE</Country> </Registration> </KeyFacts> </FundFacts> <Name>Fund22222 </Name> <FundFacts> <KeyFacts> <Registration> <Country>PT</Country> </Registration> </KeyFacts> </FundFacts> </Fund> </Funds> </FundsXML>
