Hi Rob,

Could you provide us with a self-contained example? The following example code works as expected:

store:read('x'),
delete node <a/>

Best,

Christian

Betreff: [basex-talk] store:read within an updating function

Hello Christian,

Allthough the store:read function returns an empty sequense I found that it still triggers the error: 'expressions must all be updating ....', when used within an updating function.

I guess this error is unnecesary.

The workaround is quite easy by using a void function[1]

[1] store:read( $name) => void()

mvgr.
