Macro containing brackets

[wellilein]

I have recorded the output of a build step (namely the VMWare list processes action). The output of this step contains brackets for one of the processes ([System process]) and is multiline (one process per line).

I would like to check whether a specific process is running, so I perform additional operations on the macro value. However, I can't get it work. In this simplified example I am looking for svchost in the list of running processes. Instead of a temporarily assigned macro I use a fixed project macro to reproduce.

Approach 1: Simply use the Instr() VBScript function.
[Instr(1, "%VMPROCESSES%", "svchost")]

This fails due to an unterminated string because the macro is expanded immediately, resulting in a new line. That's clear.

Approach 2: Use Application.ExpandMacros
[Application.ExpandMacros("%VMPROCESSES%")]

This of course has the same issue and I need to use double % signs to pass %VMPROCESSES% as a string to be expanded later by the method.

Approach 3: Double percentage
[Application.ExpandMacros("%%VMPROCESSES%%")]

This complains about the brackets, although my understanding is that only macros are expanded, not functions. For macros and functions, there is ExpandMacrosAndScript().

Approach 4: use vbld_AllMacros()
[vbld_AllMacros()("VMPROCESSES").Value]

This also complains about brackets.

Funny: Message box is ok
[msgbox (vbld_AllMacros()("VMPROCESSES").Value)]

Approach 5: doubling the brackets once
[Replace(Replace((vbld_AllMacros()("VMPROCESSES").Value), "[[", "[[[["), "]]", "]]]]")]

This does not work.

Funny: with a message box, it works, but replacement is not done.
[msgbox (Replace(Replace((vbld_AllMacros()("VMPROCESSES").Value), "[[", "[[[["), "]]", "]]]]"))]

I attached my build script.
Steps 1, 2, 3, 4, 6 fail.
Steps 5, 7, 8 with message boxes are successful (but replacements are not made).
