Hi Presenly Iam adding roPosterScreen Items using a array…
But I want this items to be added from a XML file and also when a menu item is selected we need get the corresponding sub menu item from XML…


screen = CreateObject("roPosterScreen")
categoryList = getCategoryList()  //Now this should be from a xml file....
screen.SetListNames(categoryList)
screen.SetIconArray(getShowsForCategoryItem(categoryList[0]))

//below two functions values  should be from xml file....
Function getCategoryList() As Object

    categoryList = CreateObject("roArray", 10, true)

    categoryList = [ "My Channel", "Add Channel","Remove Channel"  ]
    return categoryList

End Function

Function getShowsForCategoryItem(category As Object) As Object

    print "getting shows for category "; category

    showList = [
        {
            ShortDescriptionLine1:"IPL",
            ShortDescriptionLine2:"Indian Premier League",
              HDPosterUrl:"pkg:/images/ipl.jpg",
              SDPosterUrl:"pkg:/images/ipl.jpg" 
        }
        {
            ShortDescriptionLine1:"Pop Channel",
            ShortDescriptionLine2:"Free Live Video Streaming,Online Broadcasts",
            HDPosterUrl:"pkg:/images/popcorn.png",
            SDPosterUrl:"pkg:/images/popcorn.png"
        }
        {
            ShortDescriptionLine1:"Roku",
            ShortDescriptionLine2:"Roku Sports Channels",
            HDPosterUrl:"pkg:/images/roku.png",
            SDPosterUrl:"pkg:/images/roku.png"
        }
    ]

    return showList

End Function

Please look at the videoplayer example code in the sdk. It is an example of parsing an xml feeds to display a hierarchy of data and filling in the content-metadata array that would be passed to an roPosterScreen. The docs also walk through XML parsing in the BrightScript Reference Section 4.5.
