[F8] Add field to XML

[digitalpencil]

Hi,
I'm currently using an XML file to load an image and menu-name into a list component and would like to add a description field to this.
I have added another attribute to my XML file called 'desc' so the file is now arranged:


<xml>
    <listitem name="Le Mans 06, 0-5" url="http://www.dedicatedmicros.com/ukftp/FLVHUB/FLV/" thumb="1.jpg" desc="some text">
        <stream name="1.FLV" start="0" len="-1"/>
    </listitem> 

After dropping a dynamic text field onto the stage instance named 'description', I have attempted to modify the xmllist.load code but despite not firing any errors, this has not resolved the issue:
That code is as follows: (changes are proceeded by '//-')

//-------------------------LIST SELECTION CHANGE-----------------------------
//Add an event listener on the list, when it triggers, run the listListener function to repopulate the list
list.addEventListener("change", listListener);


//Function that loads the XML file, parses it, and builds the list of available video clips
    var xmllist = new XML();          //setup a variable to hold the XML
    xmllist.ignoreWhite = true;
    xmllist.load( "video_playlist.xml" );     //load the XML file
    //The following gets called when the XML has been loaded
    xmllist.onLoad = function( status )  {
        if ( !status )
            trace( status );
        var entries = this.childNodes[0];
        var playlists = {};
        var nav = [];
//-        var description = {};
//-        var descrip = [];
        for ( var i = 0; i < entries.childNodes.length; i++ ) {
            var entry = entries.childNodes[i];
            if ( entry.nodeName == "listitem" )
                //builds array of video clip names
                playlists[entry.attributes.name] = entry;
            else if ( entry.nodeName == "menu" ) {
                //builds array of available videos
                for ( var j = 0; j < entry.childNodes.length; j++ )
                nav[j] = playlists[entry.childNodes[j].attributes.name];
                
//-            if ( entry.nodeName == "desc" ) {
//-                //builds array of descriptions
//-                description[entry.attributes.desc] = entry;
//-                for ( var k = 0; k < entry.childNodes.length; k++ )
//-                descrip[k] = //-description[entry.childNodes[k].attributes.desc];
            
}
                
            } //end else if
        } //end if

        //sends the array of videos to the listbox UI
        list.dataProvider = nav;
        desc.text = descrip;
    } //end xmllist.onload 

Was hoping someone could help point me in the right direction as to where i'm going wrong with this one as i've attempted various things now but have not had success with any.

If anyone can offer any assistance here I would be very appreciative,

Thanks,
Dave

What does the code currently do? Does it populate anything at all into the dropdown?

Thanks for the reply,
The code currently populates a list component with the 'listitem name' and, with the use of the cellrenderer class, thumbnail images within the listbox.
All I basically want to do is add a new attribute to the XML doc in which I can store a description that will load into a dynamic textbox on selecteditem change.
The commented out sections (code preceeded by '//-') is the code I have attempted to use to load in the contents of the description attribute from the XML doc.
Am hoping you point out where I've gone wrong..

Thanks

this is the method i use ( no exp. with cellrenderer class yet )
to avoid conflict with reserved words i have changed - name,url,start
and altered the format of the xml slightly

hope you can adapt this to your project

xmllist = new XML();
xmllist.ignoreWhite = true;
xmllist.load("video_playlist.xml");

xmllist.onLoad = function(){
rootNode = xmllist.firstChild;
leng = rootNode.childNodes.length;

 for(var i=0; i<leng; i++){
nom = rootNode.childNodes[i].attributes.vname;
vurl = rootNode.childNodes[i].attributes.vurl;
thu = rootNode.childNodes[i].attributes.thumb;
des = rootNode.childNodes[i].attributes.desc;
str = rootNode.childNodes[i].attributes.stream;
sta = rootNode.childNodes[i].attributes.vstart;
len = rootNode.childNodes[i].attributes.len;

list.addItemAt(i,{label:nom, vurl:vurl, thu:thu,
desc:des, str:str, sta:sta, len:len})      
} 
} 

obj2 = new Object();
obj2.change = function(comp){
vid = comp.target.selectedItem.label;  trace(vid);
url = comp.target.selectedItem.vurl;  trace(url);
thumb = comp.target.selectedItem.thu;  trace(thumb);
desc = comp.target.selectedItem.desc;  trace(desc);
stream = comp.target.selectedItem.str;  trace(stream);
vstart = comp.target.selectedItem.sta;  trace(vstart);
lenth = comp.target.selectedItem.len;  trace(lenth);
trace("---------------");
_root.description.text = desc;
}
list.addEventListener("change", obj2);

<xml>
<listitem vname="Le Mans 06, 0-5" vurl="http://www.dedicatedmicros.com/ukftp/FLVHUB/FLV1/" thumb="1.jpg" desc="some text" stream ="1.FLV" vstart="0" len="-1">
</listitem>
<listitem vname="Le Mans 05, 0-4" vurl="http://www.dedicatedmicros.com/ukftp/FLVHUB/FLV2/" thumb="2.jpg" desc="more text" stream ="2.FLV" vstart="10" len="10">
</listitem> 
</xml>

Thx again!

Hi, thanks again for your assistance..

Tried your code and got the description box working but it crippled the list in the process. Have attempted to converge the two together but am not great with XML and am beginning to run out of ideas on this one.
Have uploaded my FLA etc and was hoping you could have a look and see if you can work out where I've gone wrong: (all files are listed at the following)
http://www.dedicatedmicros.com/ukftp/docs/
or, i've also zipped it all up for convnience if you prefer

Thanks for the advice,
