An XPath expression for an XLIFF file that does not specify the XLIFF namespace would look like this:
../child::note
If the file contains the XLIFF namespace as default namespace the XPath expression would be as follows:
../child::pdns:note
In order for the comment extraction to work, please double click on
Data Element, and change the note definition from:
parent::*/descendant::note
to
parent::*/descendant::pdns:note .
Note: comments turning blue is a confirmation that the setting is right
