String comparison in batch file never matching

Question

I have the following snippet

setlocal EnableExtensions EnableDelayedExpansion
SET copyableTomcat="C:\test\source"
SET tomcatNode[2]="C:\test\source"

set x=2

IF %copyableTomcat% == %%tomcatNode[%x%]%% (
    call echo "ignoring " %%tomcatNode[%x%]%%
) ELSE (
    call echo "done"
)

However, the if statment is NEVER matching, and always goes into the else statement.

I am unsure if i am mistypying something or missing something completely

%%var%% only works with call.

Use ! to expand the value since you're already using delayed expansion
No need for quotes in echo
No need to use call with delayed expansion in this case

IF %copyableTomcat%==!tomcatNode[%x%]! (
    echo ignoring !tomcatNode[%x%]!
) ELSE (
    echo done
)
