Firstly, I suspect you want the preceding-sibling axis rather than the
preceding axis.

The position() function returns the position of a node within the sequence of
nodes being processed, not its position within an XML tree. If you use it
within a predicate, it's the position of the item being tested within the
sequence of things being tested, which in your case is the sequence of
preceding text elements, in reverse document order.

To test whether a node is the first element child of its parent, use

not(preceding-siblling::*)
