    XML problem

    MPetroDesigns
      Hi Guys,

      We have an assignment in our Flex class to build a mini website showcase. The website must have 3 links at the top, which in my case are Photography, Automotive, and Personal/Portfolio. The website must pull data from an XML file. Basically the way I set it up is in 3 states, where base is photography, etc. I am also using the "repeater" function to load in all of the img's from the XML.

      I've figured out abut 85% of it but am faced with a problem which I can't seem to address.

      When the user clicks on Automotive, or Personal/Portfolio, I only want a section of the XML file to be loaded.

      This is the code I'm using to pull from the XML
      quote:

      <mx:Repeater id="myRepeater" dataProvider="{myXML.lastResult.gallery.photography}">
      <mx:HBox width="100" height="95" horizontalAlign="center" verticalAlign="middle" verticalScrollPolicy="off" horizontalScrollPolicy="off">
      <mx:Image width="80" height="80" completeEffect="bigFade" source="{myRepeater.currentItem.img}" rollOverEffect="myZoom" rollOutEffect="myZoomOut" click="getImage(event)"/>
      </mx:HBox>
      </mx:Repeater>



      I've tried making an If statement saying
      if( currentState=='automotive' ){
      myRepeater.dataProvider="{myXML.lastResult.gallery.automotive}"
      }

      But that didn't work..

      Any ideas? I can send who ever the .zip file and/or post the current app online so you can see it visually if that helps.

      Thanks,

          Do not bind directly to lastResult. There are many reasons and this is one.

          Instead, use a result handler function. In that function, use an e4x expression to get the nodes you want, then assign that XMLList to the Repeater's dataProvider.

            I'm pretty new to Flex, and have no idea what an e4 expression is. Can you go into a bit more detail and/or give me an example of what mine will look like? Thanks again.

              This, "lastResult.gallery.automotive" is an e4x expression. An "e4x expression" is just the way you specify a node list in AS3's XML class.

              How are you getting your data? HTTPService? Can you set up a result handler?

              when I get to my other machine I will post some example code.

                Oh, gotcha.

                Yeah I'm using HTTPService

                <mx:HTTPService id="myXML" url="../assets/pictures/pictures.xml"/>

                If you want, I can send you the .zip to your email?
