Removing all text nodes from a given node

[Narokman]

I've written a method that is supposed to remove all text nodes from a
given node and also from its child nodes. The given node is, for
example,
created from following XML:
--------------
<?xml version="1.0" encoding="utf-8" ?>

<L1>L1 Text
<L2>L2 Text
<L3>L3 Text</L3>
</L2>
<L2_1>L2_1 Text</L2_1>
<L2_2>L2_2 Text</L2_2>
</L1>
--------------

The method I've written is :

--------------
public static void removeEmptyText(org.w3c.dom.Node n) {
org.w3c.dom.NodeList nodeList = n.getChildNodes();

for (int i = 0; i < nodeList.getLength(); i++) {
org.w3c.dom.Node node = nodeList.item(i);
int type = node.getNodeType();


// if (type == ELEMENT_TYPE) {
if (node.hasChildNodes()) {
removeEmptyText(node);
}else if (type == TEXT_TYPE) {
n.removeChild(node);
}
}//End of for-loop
}
--------------

This method only works for removing text nodes in the "L1" level.
It fails to remove text nodes in child nodes of "L1".
Any ideas?
If anybody has better way to remove text nodes from a node, I would
also really appreciated.

Thanks.
