The position() function gives you the position of the context node amongst the other nodes you're looking at. If you did: child::Level2[position() = 1] or the equivalent: Level2[1] then you'd get the first Level1 child of the context node. If you did: descendant::Level2[5] then you'd get the fifth Level2 descendant of the context node. If you did: following-sibling::Level2[2] then you'd get the second following sibling of the context node. Similarly, if you did: preceding-sibling::node()[1] then you get the immediately preceding sibling of the node (preceding-sibling is a reverse axis, which means that positional predicates, like the one hear, count in reverse document order, so you get the nearest sibling node). What you need, then, is simply: <Preceding_GID> <xsl:value-of select="generate-id(preceding-sibling::node()[1])"/> </Preceding_GID> Although you could use: <Preceding_GID> <xsl:value-of select="generate-id(../node()[position() = $cpo - 1])"/> </Preceding_GID> if you really wanted (it's likely to be a lot less efficient). Note that there's no need to use xsl:element to create your elements if you know what their names are.
