Re: False positives in editing data

Problem solved!

I went through a convoluted process to determine whether any of the
initial numbers began with a zero. I simplified it to:

i_thNumberHasLeadingZero = (n[i] =~ /^0+/) ? true : false

I apologize for raising the question. My excuse is that I was
flailing about unable to figure out what was wrong. After I posted,
I took a harder look and realized my big mistake: I needed to use the
KISS method :-)

If you solved your problem then you won't need this.
But, just in case you are interested in looking at it from a little
different view....
It is not a complete solution, just an idea.

inp = <<DATA
05Topic 5
1Topic 1
2.002.1Topic 2.2.1
2.1Topic 2.1
2.2.02Topic 2.2.2
DATA

err1 = inp.select{|a| a =~ /^0|\.0/}
puts "A number may not start with zero" unless err1.empty?
print err1
puts
err2 = inp.select{|b| b =~ /^\d+\.\d+\.\d/}
puts "No more that two numbers may be prefixed" unless err2.empty?
print err2

Hi Ryan,

different view....

I AM interested, and it's a great idea. Real Ruby rather than my C-
flavored Ruby :-)

Just for our mutual amusement, I replaced your first criterion:

err1 = inp.select{|a| a =~ /^0|\.0/}

with:

err1 = inp.select{|a| a =~ /^0|^\d*\.0/}

to preclude false hits where the text proper might contain ".0", e.g.,
"7How to get 5.05% interest"

Bottom line: Your code is what I really need. Thanks, again.

Best wishes,
Richard
