[julia-users] Variable scope in a function

[Brandon Booth]

I've defined a function that is something like the pseudo code below. It 
only works properly if i define the subset1 and subset2 arrays outside of 
the function. Any suggestions on how to make it work without having to 
define the arrays outside of the function? I've read some of the discussion 
regarding scope and I'm still not clear why this doesn't work.

Thanks.

Function parse
  
  create db connection
  create schema
  create sink
  define baseurl
 
  for url in urls

    pg = xp_parse(url)
    subset1 = xpath(pg,subset1 path)
    subset2 = xpath(pg,subset2 path)

    for s in subset1
        build a dataframe
        stream dataframe to db
    end

    same for subset2
  end
end
