I suppose that you don't want '11.1' to be affected.

raw_data="""
1.1    2.3
2.2    11.1
4.3    1.1
"""

data = filter(None, [line.strip().split() \
                     for line in raw_data.split('\n')])
processed = [[item == '1.1' and 'X.X' or item for item in pair] \
              for pair in data]
result = "\n".join(["\t".join(pair) for pair in processed])

Not sure this is the fastest solution...

BTW, may I ask why you don't want to use regexp ?
