Try select="(UniqueInfo | following-sibling::Item[1]/UniqueInfo)[1]

for example, in a variable:

<xsl:variable name="uniqueInfo" 
  select="(UniqueInfo | following-sibling::Item[1]/UniqueInfo)[1]"/>

This relies on the fact that the result of a union (|) is always in document
order, and "[1]" will therefore select whichever comes first: the UniqueInfo
child of this item, or the UniqueInfo child of the next item.
