Splitting a string

[thechad90000]

I'm attempting to split a string like this

[label] opcode [arg1] [arg2]

The label and arguments are optional but there is always an opcode and there is always whitespace where the label is if it isn't there. Right now I have this:

while (myFile.good())
	{
		getline(myFile, line, '\n');
		
		if (line[0] == '#')
		{
			continue;
		}
		
		
		if (line[0] != '\t' && line[0] != ' ')
		{
			
			string delimeters = "\t,";

			int current;
			int next = -1;

			do
			{
				current = next + 1;
				next = line.find_first_of( delimeters, current);
				label = line.substr( current, next - current );
				cout << label << endl;
			}
			while (next != string::npos);
		}
		
		
	}

The cout << label << endl; is there to see what I have in there. The output I'm getting is:

TOP
NOP
VAL
INT 0
TAN
LA
2
1

When I should just be getting:

TOP
VAL
TAN

Here is the original text file I'm reading in from

# Sample Input

	LA 1,3
	LA 2,1
TOP	NOP
	ADDR 3,1
	ST 3, VAL
	CMPR 3,4
	JNE TOP
	P_INT 1,VAL
	P_REGS
	HALT
VAL	INT 0
TAN	LA	2,1

Why are you using the do-while loop? If all you're doing is extracting labels, and you can't have more than one label per line... why loop through the line after you've already found a label?
