Exception handling issue in ruby

Question

In the following code i want to handle the exception.if msg[0] not found i have to catch that exception message msg[2] in rescue and if it is found put the success message msg[1]

puts "Verifying Home Page"
 def verifyHomepage(*args)
 begin
  args.each do |msg|    
    page.find(msg[0])
    puts msg[1]
    rescue
    puts msg[2]      
  end
end
end
verifyHomepage(['#logoAnchorr', 'logo anchor found', 'Logo anchor not Found'], ['.navbar-inner', 'Header Bar found', 'Header Bar  not Found'])

In the above code iam getting error sysntax error unexpected keyword rescue expecting keyword end

Is it because the rescue is inside the args.each block?

Salil has pointed you where to fix,that's correct. Now The below approach also you could adapt:

puts "Verifying Home Page"

def verifyHomepage(*args)
  args.each do |msg|   
    next puts(msg[1]) if page.find(msg[0]) rescue nil  
    puts msg[2]     
  end
end
a = [['#logoAnchorr', 'logo anchor found', 'Logo anchor not Found'], ['.navbar-inner', 'Header Bar found', 'Header Bar  not Found']]
verifyHomepage(*a)

Output:

Verifying Home Page
Logo anchor not Found
Header Bar  not Found

You have to write begin inside the block

puts "Verifying Home Page"
def verifyHomepage(*args)  
    args.each do |msg|
      begin
        page.find(msg[0])
        puts msg[1]
      rescue
        puts msg[2]
    end
  end
end
verifyHomepage(['#logoAnchorr', 'logo anchor found', 'Logo anchor not Found'], ['.navbar-inner', 'Header Bar found', 'Header Bar  not Found'])

Is it a good idea to have an end after the rescue statement, at all?
