recurse xml remove all but first child

Hi,

I've tried searching for a solution and tried to adapt the code i found but I'm stuck.

I simply want to:

Delete all children bar the first child of all elements named "gr_name".

I've been looking at Remove xml element using JS[CS3] and got some inspiration.

I have the below code, which works if there is only two child elements.

If there is three or more I have to rerun the code which removes more elements.

I would very much appreciate if someone can help me locate the error or indicate what is missing.

var myDoc = app.activeDocument;

Table_Remove (myDoc);

function Table_Remove(elm)

{

    for (var i = 0; i < elm.xmlElements.length; i++)

        {

             if(elm.xmlElements.markupTag.name == "gr_table")

               {

                    for (var i2 =1; i2 < elm.xmlElements.xmlElements.length; i2++)

                        {

                            elm.xmlElements.xmlElements[i2].remove();

                        }

               }

            Table_Remove(elm.xmlElements);

        } 

}
