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