The result as a Java object

numberValue

public abstract double numberValue()
Returns the result as a number value. Returns 0 or 1 for a boolean result, the parsed value for a string result, the value of a number result, or the parsed value of a node-set.
Returns:
The result as a number value

stringValue

public abstract String stringValue()
