I'm trying to parse a file that looks like this:

text....
text....
numbers....

IDS_SOMETHIGN_SOMETHING "giving you cookies in a sec"
IDX_SOMETHING_SOMETHIGN "hi again"
IDY_SMOTHIENG_SOMETHIGN_SOMTHIGN "HELO world"
ID_ONE_THING "hello how are you"
ID_ONETHINGTOO "give me a number"
ID_ONEMORE_THING_ANDMORE "this are strings"

I'm trying to create a hash table but i'm not sure what's wrong with my
delimeters:

class Parser

  table = { }
  IO.foreach('resurcefiletest') { |line|
   if line =~ /^ID* (.*?) = \s* " (.*?) "/x
    #if line =~ /^ \s* " (.*?) " \s* = \s* " (.*?) "/x
      table[ $1 ] = $2
    end
  }

  #puts table["StaplingTitle"]
  p table

end

can somebody give me a hand?

thanks,
mike

//x just gets confusing. Make your regexp simple:

table = {}

File.foreach filename do |line|
   next unless line =~ /^ID(\S+) "(.*?)"/
   table[$1] = $2
end

Thanks for your help eric,

I tried what you said but nothing gets stored in the table...and i'm
nothing seeing why. do you see it?

thanks

change the space to \s+

your original regexp didn't work because there is no =, but I agree with eric that your use of /x makes it too complex.
