[WiX-users] Escaping brackets [ ] in merge modules (MSM)

[Erkan C. <ec...@di...>]

There are cases where I need to have brackets (square brackets) in certain actions like running a SQL script that requires brackets or in an XPath expression. You can escape them in a regular installer (MSI) project by using  [\[] or [\]], to open and close respectively. When I do the same in a merge module, it doesn't work. For instance, if I have a property called PROP1 with a value of "Value1", if I need, "[Value1]" as a literal, I can do [\[][Value1][\]] and get what I need. However, in a merge module, the same syntax produces an empty string. Does anyone have any idea why it doesn't work the same way in a merge module? Any ideas on how to work around this?

Thanks in advance.
