Formular to Extract Numbers out of a string

[Seb_Blandin]

Hello everyone,
I receive in a single text field this kind of data:
+1 * 1+0 * 2+0 * 3+0 * 4+0 * 5+0 * 6+0 * 7+0 * 8+0 * 9+0 * 10
or
+1 * 4+1 * 5+0 * 6+0 * 7

This is the number of kilos that needs to be sent in the appropriate package. I wonder how I could retrieve the 1*1 from the first line, or, for the second line, 1 * 4 and 1 * 5

I was thinking about some regex expression but my knowledge is poor in that field. Anyone would have an advice?

Thanks in advance
