xslt copy xml document for each occurance of a repeating node

Hi, I am attempting to copy the contents of an entire XML document once for each occurrence of a repeating node (including it's children) within the same document using XSLT(version 1.0).  Each instance of the original document should contain only one of the repeating nodes (RepeatingNode).   Basically, I need to change the repeating nodes into a single occurrence and wrap them in a new root node.  The elements in the XML can be anything, however the name of the repeating node is always the same.  There are thousands of elements in the XML document, so I can't simply just build it.  The copy needs to be generic.   For example if I have the following XML, I need these results.

<?xml version="1.0" encoding="UTF-8"?>
<XMLTopNode attr1="1234" attr2="hithere" attr3="thanks">
