Examples of org.jaxen.BaseXPath.booleanValueOf()

org.jaxen.BaseXPath.booleanValueOf()

Retrieve a boolean-value interpretation of this XPath expression when evaluated against a given context.

The boolean-value of the expression is determined per the boolean(..) core function as defined in the XPath specification. This means that an expression that selects zero nodes will return false, while an expression that selects one-or-more nodes will return true.

@param node The node, nodeset or Context object for evaluation. This value can be null. @return The boolean-value interpretation of this expression.
