Subject: How to make an array of hashes to a single array with all the values of these hashes ?

Take a look at this, 
	puts myvalue.inspect 
shows this here:

[{:url=>"http://www.ruby-lang.org/"}, {:url=>"http://www.ruby-lang.org/en/20020101.html"}, {:url=>"http://en.wikipedia.org/wiki/Ruby_programming_language"}, {:url=>"http://en.wikipedia.org/wiki/Ruby"}, {:url=>"http://www.rubyonrails.org/"}, {:url=>"http://www.youtube.com/watch?v=JMDcOViViNY"}, {:url=>"http://www.rubycentral.org/"}, {:url=>"http://www.zenspider.com/Languages/Ruby/QuickRef.html"}, {:url=>"http://www.rubycentral.com/book/"}, {:url=>"http://poignantguide.net/"}]


That's an array of hashes or? But how to get this to an array of the values of these hashes? Like my_new_array == ["http://www.ruby-lang.org/","http://www.ruby-lang.org/en/20020101.html","http://en.wikipedia.org/wiki/Ruby_programming_language",...].  

	myvalue.each {|arr|  puts arr.values }
gives me:

http://www.ruby-lang.org/
http://www.ruby-lang.org/en/20020101.html
http://en.wikipedia.org/wiki/Ruby_programming_language
http://en.wikipedia.org/wiki/Ruby
http://www.rubyonrails.org/

http://www.rubycentral.org/
http://www.zenspider.com/Languages/Ruby/QuickRef.html
http://www.rubycentral.com/book/
http://poignantguide.net/

what's correct! But I can't save it to an array. Why? I tried
	myvalue.each {|arr|  @my_new_array << arr.values }
	puts @my_new_array
But I just get nil :( ? I can't make an array out of this.
