Ruby pros:
I am a Ruby newbie, and would appreciate help with the following to jump-start a project.
1)- How can I read the contents of a text file into a two-dimentional array, such that one dimension are the rows of text and the other dimension are fields that occur on each line as delimited by some character.
Note: A tutorial I'm using shows that I can use the readlines method
to create a one-dimensional array, with each line from the source file
an element. It seems like I ought to be able to use the same or
similar method to include the second dimension (delimited fields in
each row).
2)- Say I have text files FileA and FileB. FileA contains a text tag in the somewhere in it called, say, “”. How can I:
- locate the tag <foobar> in FileA and
- replace <foobar> with the entire contents of FileB.
In short, I want to insert FileB in FileA where the <foobar> tag is,
then delete the tag.
Thanks!

File(“whatever”).readlines.collect { |line|
line.split “separator”
}
comes to mind here.

if the files are not too large, you could read them as a whole
and then just do string substitution.
a = File(“a”).read
b = File(“b”).read
a.gsub(//, b)

If “a” is large:
require ‘tempfile’
require ‘ftools’
t = Tempfile.new(“foobar”)
b = nil
IO.foreach(“a”) do |line|
t.print(line.gsub(//) do
b ||= File.open(“b”) {|b| b.read}
end)
end
File.copy(t.path, “a”)

Too, except that it’s an evening here.
