Return an attribute's value as a Number.
The first parameter, name, is a string with the name of the attribute being checked. For example, calling myXML.getNum('id') returns the element's id attribute as a number.
The second parameter, defaultValue, is optional. If a number is passed, as in myXML.getNum('id', -1), it will be returned if the attribute doesn't exist or can't be converted to a number.
Note: Use myXML.getString() or myXML.getNum() to return an attribute's value.
