s = <<EOS
a1\t  b1
a2\tb2
EOS

s.each{|e|
    a = e.strip.split("\t")
    p a[1]

}

output:
"  b1"
"b2"

expected output:
"b1"
"b2"

What is wrong?

This works fine ...

s.each{|e|
    a = e.gsub(' ','').split("\t")
    p a[1]

}

2008/5/1 Amasa Masiarek <a...@masiarek.com>:

k$ qri String#strip
----------------------------------------------------------- String#strip
     str.strip   => new_str
------------------------------------------------------------------------
     Returns a copy of str with leading and trailing whitespace removed.

Leading and trailing doesn't mean internal.  So:

"a1\t b1".strip #=> "a1\t b1"

Hi --

Your expectation :-) Sorry, I couldn't resist.

strip removes space on the right and left. If you start with
"a1\t b1\n", the stripped version is "a1\t b1". If you split that on
\t, you get "a1" and " b1". At no point have you removed the middle
space.

Or split on whitespace instead of on tabs alone.

s.each{|e|
   a = e.split("\s")
   p a[1]
