Nesting nodes in xslt

[Beatz]

I am trying to create an XSLT to transform an XML document, but I'm having trouble with grouping. I have no problems pulling out information for a single object, but I do not know how to group certain elements using xslt. I have tried xsl:for-each-group and xsl:key for grouping but i was not succesful in transforming. Input:\[code\]<?xml version="1.0" standalone="yes"?><root> <node1> <ID>2</ID> <Name>ABCDE</Name> <Age>21</Age> <Skills>C++ C#</Skills> <worklocation>IN</worklocation> <designaton>Engineer I</designaton> </node1> <node2> <ID>3</ID> <Name>EFGH</Name> <Age>12</Age> <Skills>java</Skills> <worklocation>USA</worklocation> <designaton>Engineer II</designaton> </node2></root>\[/code\]Desired Output:\[code\]<root> <node1> <ID>2</ID> <Name>ABCDE</Name> <Age>21</Age> <workInfo> <Skills>C++ C#</Skills> <worklocation>IN</worklocation> <designaton>Engineer I</designaton> </workInfo> </node1> <node2> <ID>3</ID> <Name>EFGH</Name> <Age>12</Age> <workInfo> <Skills>java</Skills> <worklocation>USA</worklocation> <designaton>Engineer II</designaton> </workInfo> </node2></root>\[/code\]
