I want to write a regex that will find strings of length 10-15 where all characters are [A-Z0-9] (spaces are ok but not other special characters). Some examples:

• ABABABABAB12345 should match
• ABAB1234ABA32 should match
• ABA BA BABAB12345 should match
• 1234567890987 should not match
• ABCDEFGHIJK should not match
• ABABAB
