Answer 1

Try this,

We needn't mention XML root tag name here so just get rid of list tag name when access XML.

Add resultFormat="e4x" to HTTPService component.

<s:HTTPService id="malls" url="assets/details.xml" resultFormat="e4x"
                   result="malls_resultHandler(event)"/>


ml = new XMLListCollection(malls.lastResult.mallD);

To

var response:XML = malls.lastResult as XML;

var mallIDXMLList:XMLList = response.mallD;             
m1 = new XMLListCollection(mallIDXMLList);

Answer 2

You can try to replace

ml = new XMLListCollection(malls.lastResult.list.mallD);

by

var xmllist:XMLList = XMLList (malls.lastResult.list.mallD);
ml = new XMLListCollection(xmllist);
