Seems you’ve stumbled upon a classic [1]; and the problem is related: Inside “database nodes” we only have a parent, but no reference to the ancestors of main-memory nodes. One more nudge to eventually get this fixed. [1] https://github.com/BaseXdb/basex/issues/919 On Sat, Aug 29, 2020 at 11:19 AM RobStapper <r.stapper@lijbrandt.nl> wrote:

Hi Christian,

☹ We’re not there quite yet. See attached snippet.

I’m still loosing my CONTEXT-element when starting the ancestor-axis from a sub element of the XML-file-element.

Best regards,

Rob

Hi Rob,

An interesting one. The mixing of external nodes and node fragments (which have different internal representations) caused some confusion.

The issue has been fixed, a new snapshot is ready to go [1].

All the best, hope you are fine,

Christian, I’m drilling down on every path in a context element embedded XML-file element. With on every step a search in the tree-structure back to the context-root. it seems to works fine. Thanks 😊😊😊 Indeed cheers, Rob Sent from Mail for Windows 10 From: Christian Grün Sent: Monday, August 31, 2020 2:38 PM To: RobStapper Cc: basex-talk@mailman.uni-konstanz.de Subject: Re: [basex-talk] ancestor axis i.c.w. fetched XML issue Hey Rob, hallo Hans-Jürgen, I have completely revised the traversal of mixed database/fragment nodes for the ancestor and preceding/following axes. In some cases, processing should even have become faster. Your testing feedback is welcome [1].
