The following one is good and shows the right answer:

Query: doc("XPath test.xml")//*[(@*)="2e"]

Compiling:

- pre-evaluating fn:doc("XPath test.xml")

- optimizing descendant-or-self step(s)

- applying attribute index

Result: db:attribute("XPathtest", "2e")/parent::*

Timing:

- Parsing: 0.59 ms

- Compiling: 30.36 ms

- Evaluating: 1.67 ms

- Printing: 0.17 ms

- Total Time: 32.79 ms

Result:

- Results: 1 Item

- Updated: 0 Items

- Printed: 24 Bytes
