Accessing the length of child nodes returns twice the original count

I've been trying to iterate the child nodes by getting the length of a item node. But, it shows double the size of the original length.

This is the XML code i've been using,

    <item>
        <title>Title 1</title>

    </item>

Java Code :

NodeList nl = doc.getElementsByTagName("item");
int length = nl.getLength();
Log.d("check", "Item i count = " + length); //shows 10
for (int i = 0; i < length; i++) {
    Node currentNode = nl.item(i); // Get the first item
    String nodetestName = currentNode.getNodeName();
    NodeList nchild = currentNode.getChildNodes(); // Get the child nodes of first item
    int clength = nchild.getLength(); // Get the length of child nodes of first item (Shows 21 but original length is 10)

What should i do?
