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.
