Searching for text in files

Hi All,

I am having trouble putting some Ruby together to search through some lines of text in a specific file.

I have one file, called siteowner.aspx, that contains a certain string that would like to compare against a static value. So far, I can pick the correct line out, but I would like to filter it for a certain string.

So far, my code is as follows:

Code:

File.open("\\path\\to\\site.aspx", 'r') do |infile|
while (line2 = infile.gets)
     
       puts 'Via Regxp, Site owner is: '+ line2 if line2 =~ (/^= /) 
    end
end

However, I am stuck with the regular expression. The above code gives me:

'Via Regxp, Site owner is: siteowner = "OWNER"

But what I would really like is:

'Via Regxp, Site owner is: "Owner".

I dont suppose someone could help me out a bit and show me where I have gone wrong?

Code:

irb(main):004:0> s = "siteowner=OWNER"
=> "siteowner=OWNER"
irb(main):005:0> puts "Owner is: #{$1}" if s =~ /.+=(\S+)/ 
Owner is: OWNER

You can use grouping to get a specific portion of a regular expression.

additionally

Code:

irb(main):008:0> "OWNER".capitalize
=> "Owner"
