Echo content when 2 Xpaths have specific value

I’m trying to only import taxonomy when 2 different fields have specific value:

This code based on 1 field is working:
[IF({category2[1][.=”0219″]})]broeken[ELSE][ENDIF]

This code based on 2 field is not:
[IF({category2[1][.=”0219″]}&&{category3[1][.=”0310″]})]broeken[ELSE][ENDIF]
This results in “Error parsing content: Unexpected symbol ‘&'”

Any ideas? Many thanks!!
