procs.stable.out
Log Message:
Finally, the last remaining XPath location step has been loop-lifted:
preceding-siblings.
The implementation falls back to applying a loop-lifted parent-step, first
--- using unique temporary iter-numbers, one for each item, we keep the
loop-lifted parent-step from pruning, and hence, get excatly one parent-node
for each context-node (item) ---
then, a slightly modified loop-lifted child-step is used to retried all children
of the just calculated parents up to the respective original context nodes.
For now, we only have kind-test push-down (like with following-sibling,
preceding & following), but no ns/loc-test push-down, yet.
While the child step should support this readily, I was not yet able to
locate and eliminate some strange bug in the calculation of candidates,
that occurs with one of our preceding-sibling tests.
Special thanks go to Jan R. for proving the initial idea of falling-back
to parent-step plus "context-node-limited" child-step.
