My question goes as the title says: is there any way to "tell" a regex there's a big blank between two fields of s string? With big I mean trailing whitespaces, or tabs, or any combination of both. The thing is I'm working with strings which I must extract some fields from. Something like:
label OPCODE operand
The regex I'm using is as follows:
"([a-z]*)(\\s)([A-Z]+)(\\s)([a-z]*)"
The problem is java only recognizes every " \s" character as just one space, and doesn't count for tabs. If anyone can help me I'd really appreciate it!
The \s metacharacter should account for tabs. What you're missing is the quantifier. You need a + or * quantifier (depending on whether you allow no space between the two segments) to detect any number of whitespaces.
