Title: Problem using removeNode()

Hi All,

I am facing a Coder's block here and would appreciate help . This is kind of long and I apologize for the same .

Using actionscript I am looping some nodes (called "location") in a XML document and based on some condition would like to remove a few "location" nodes from the XML . Here's my initial code

for (var locNode:XMLNode=aNode.firstChild; locNode != null; locNode=locNode.nextSibling){
        if (locNode.nodeType == 1 && locNode.nodeName=="location"){
                var exclude:Boolean = false;
                if (some condition here){
                        exclude = true;
                }              
        }
        if(exclude==true){
                loclNode.removeNode();
        }
}

The above code does not work, because after removing the first "location" node, the loop is never executed again as loop condition locNode != null is not fullfilled (because the locNode being evaluated just got deleted).

I tried to solve this by having another pointer (called delNode) moving along with locNode and using delNode to remove nodes , while keep moving locNode on to next sibling . The problem I now face is that after delNode deletes a node, I am not able to have it catch up with locNode . Here's the code

for (var locNode:XMLNode=aNode.firstChild; locNode != null;){
        if (locNode.nodeType == 1 && locNode.nodeName=="location"){
                var exclude:Boolean = false;
                if (some condition here){
                        exclude = true;
                }
        }
        if(exclude==true){
                locNode=delNode.nextSibling;
                delNode.removeNode();
                //would like some kind of statement here to have delNode catch up with locNode
        }else{
                locNode=locNode.nextSibling;
                delNode=delNode.nextSibling;
        }
}


Would appreciate any suggestions / modifications.


Thanks
