[SOLVED] SED: Pattern repitition regex matching

Fairly straightforward, but I'm having an awful time getting what I thought was a simple regex to work. I'll give the command I was playing with, and I'm aware why this one doesn't work (the 1,3 is off the A-Z, not the whole expression), I just don't know what the fix is:

Actual Output(s):
Code:
$ echo "This is a test 0A2B9C 0A 3B4C" | sed 's/[0-9][A-Z]\{1,3\}/X/g'
This is a test XXX X XX
$ echo "This is a test 0A2B9C 0A 3B4C" | sed 's/[0-9][A-Z]\{1,3\}/X/' 
This is a test X2B9C 0A 3B4C

Desired Output:
Code:
This is a test X X X

Thanks, just banging my head on this one.

GO-TESTFUNC(7)						 Miscellaneous Information Manual					    GO-TESTFUNC(7)

NAME
go - tool for managing Go source code DESCRIPTION
The 'go test' command expects to find test, benchmark, and example functions in the "*_test.go" files corresponding to the package under test. A test function is one named TestXXX (where XXX is any alphanumeric string not starting with a lower case letter) and should have the sig- nature, func TestXXX(t *testing.T) { ... } A benchmark function is one named BenchmarkXXX and should have the signature, func BenchmarkXXX(b *testing.B) { ... } An example function is similar to a test function but, instead of using *testing.T to report success or failure, prints output to os.Stdout and os.Stderr. That output is compared against the function's "Output:" comment, which must be the last comment in the function body (see example below). An example with no such comment, or with no text after "Output:" is compiled but not executed. Godoc displays the body of ExampleXXX to demonstrate the use of the function, constant, or variable XXX. An example of a method M with receiver type T or *T is named ExampleT_M. There may be multiple examples for a given function, constant, or variable, distinguished by a trailing _xxx, where xxx is a suffix not beginning with an upper case letter. Here is an example of an example: func ExamplePrintln() { Println("The output of this example.") // Output: The output of // this example. } The entire test file is presented as the example when it contains a single example function, at least one other function, type, variable, or constant declaration, and no test or benchmark functions. See the documentation of the testing package for more information. AUTHOR
