In the example, the function searchPrice() tests whether the current node

is an element:

if(node.nodeType == 1)

{

if(node.nodeName == “price”)

output.value += (getText(node) * rate) + “\r”;

var children,

i;

children = node.childNodes;

for(i = 0;i < children.length;i++)

searchPrice(children.item(i),output,rate);

}
