Examples of org.jaxen.XPath.numberValueOf()

org.jaxen.XPath.numberValueOf()
Retrieve a number-value interpretation of this XPath expression when evaluated against a given context.
The number-value of the expression is determined per the number(..) core function as defined in the XPath specification. This means that if this expression selects multiple nodes, the number-value of the first node is returned.
@param The node, nodeset or Context object for evaluation. This value can be null @return The number-value interpretation of this expression.
