then Array products would look like this:
[abc][def]
[ghi][jkl]
[mno][pqr]
[stu][vwx]

Now, what I want to do is use gsub with a regex on def, jkl, pqr, vwx.

Of course, this is just an example, and the actual array is much bigger.

How do I access those array fields? Maybe iterate over the array somehow?

Thanks for your help.

Question : Ruby: Iterating over multidimensional array

Hi experts,

I started working with with Ruby and this looks like a rather simple problem I think, but still couldn't solve it.

products = Array.new

doc.search( "//td[@class='foo']" ).each do |foo|
     products << foo.inner_html.split(',')
end

NB: search is a Hpricot (ruby gem) method that finds all

where class='foo' in a previously loaded HTML document and returns its contents (inner_html).

Now this seems to yield an array of arrays (2D array).

e.g. if the HTML document contains
abc,defghi,jklmno,pqrstu,vwx

Answer : Ruby: Iterating over multidimensional array

Is this what you want?  "Change the values" is a pretty vague description of what  you're trying to do.

# replace some text in each 2nd element
products.each do |foo, bar|
  bar.gsub!("the", "The")
end
