@dimpiax, thanks for taking an interest, and yeah, sorry that the comment system is not letting xml code through, so I’m not 100% sure what you are saying. Your comment did prompt me to take another look at this though and come up with the following which i think is a more compact alternative to your function.

In my original line, the use of @ is quite intolerant if presented a node without the named attribute. The ‘attribute’ keyword is far more tolerant. so…

To delete any/all nodes from theXMLObject which match the expression (in this case nodes with attribute ‘test’ of value ‘marker’) :

var xlist:XMLList = theXMLObject..*.(attribute("test")=="marker"); for( var i:int = xlist.length(); i > 0 ; i-- ) delete xlist[ 0 ];

Since the xlist:XMLList references the original theXMLObject instance, we are actually deleting nodes from theXMLObject via xlist.

not so good, i.e you have next xml:
var xml : XML =

[code]
function deleteNodesWithAttribute(child : XMLList, attr : String, exist : Boolean = true) : void {
var list : XMLList;
if(exist) list = child.(attribute(attr).length());
else list = child.(attribute(attr).length()==0);

var index : uint = list.length();
while(index--) delete list[0];
}
[/code]

deleteNodesWithAttribute(xml.items, “country”);
In result: it’ll delete all with attribute “country”.
