Subject: Manipulating an Array Element

Hi All,

I am saving some html code in an Array, I then want to extract certain
values from the html code.

I have saved the html code into an Array but having difficulty
manipulating the elements to extract the exact value that I require from
the html code.

Here is the code:

#searches for images in the page which indicate platform number and
stores them in an array
    platImages = (@doc/'img[@width^="54"]')

    #above search returns an unwanted image, so delete
    platImages.pop
    #puts platImages

    #go through images names to get platform number
    platImages.each { |img|
    #convert element to string
                img.to_s

                #in this part, I have tried various string manipulation
methods to extract the values that i need, but doesn't seem to work, it
either returns nil for each element or throws an error

    puts img
    }

Any help is greatly appreciated.

Saeed.
