Example 2: Inserting Namespace-Compensated Element Fragments
This example extracts a namespace-compensated element fragment (
m:reservation) from the input XML #2 (highlighted section), and inserts it both before and after the
a element from the input XML #1. The output XML shows the results, with the inserted content highlighted.
