merge two regular expression in validator

[turbovps]

I have these two expressions:\[code\][a-zA-Z''-'\s]*\[/code\]or\[code\][?????????????????????????????????\s]+$\[/code\]I want to use them in expression validator and I don't know how to merge them.Actually I need validator to valid just these two expressions or any combination of them.I have tested \[code\]|\[/code\] too.
