xml tool Table

want to use HSM Advisor to manage my tools it has a xml export, is there a linuxcnc converter or xml plugin ?

I'm not aware of an XML import.
It is possible to use an external database for tool management:
linuxcnc.org/docs/devel/html/tooldatabase/tooldatabase.html

As an alternative it might be possible to convert the xml tool data to ordinary list data used in linuxcnc (eg by a custom python script):
linuxcnc.org/docs/devel/html/gcode/tool-....html#sec:tool-table
