drop a previously added xml layer

hi,
i have a problem with getURL method.
using the following code i add the xml file to existing svg content.

var new_node //global variable
function get_url(evt)
{
svgdoc = evt.target.ownerDocument
getURL("rivers"+count+".xml",callback)

}
function callback(data)
{
if (data.success)
{
new_node= parseXML(data.content,svgdoc)

svgdoc.getElementById("base").appendChild(new_node)
}

then i try to drop that xml file using following method.

bnode=svgdoc.getElementById("base") //base--parent of the added layer
bnode.removeChild(new_node)

but this give error like DOMERROR ......

if you can pls help me
regards,
kelum

Why not use this ?

bnode=svgdoc.getElementById("base") //base--parent of the added layer
bnode.parentNode.removeChild(bnode)
