Method

IntegergetIntAttributeValue(Node node, String attribute)
get Int Attribute Value 
String value = getAttributeValue(node, attribute);
if (value == null)
    return null;
return Integer.parseInt(value);
intgetIntAttrId(Node aNode, String aAttrName)
Looks up the attr and returns the int of it or returns -1 
String idStr = findAttrValue(aNode, aAttrName);
if (idStr != null && idStr.length() > 0) {
    try {
        int id = Integer.parseInt(idStr);
        if (id > -1 && id < Integer.MAX_VALUE) {
            return id;
    } catch (NumberFormatException e) {

IntegergetIntegerAttribute(Node n, String attributeName)
get Integer Attribute 
Node attrib = n.getAttributes().getNamedItem(attributeName);
if (attrib == null)
    return null;
String value = attrib.getNodeValue();
assert (value != null);
return new Integer(value);
IntegergetIntegerAttribute(Node node, String att_name)
Return the value of an attribute of a node as an integer number or null if the attribute is not present. 
if (node == null)
    return null;
