Examples of VariableContext

org.codehaus.preon.el.ctx.VariableContext
org.jaxen.VariableContext
Resolves variable bindings within an XPath expression.
Variables within an XPath expression are denoted using notation such as $varName or $nsPrefix:varName, and may refer to primitive types (Boolean, Number or String), node-sets or individual XML nodes.

When a variable is bound to a node-set, the actual Java object returned should be a java.util.List containing XML nodes from the object-model (dom4j, JDOM, DOM, EXML) being used with the XPath.

A variable may validly be assigned the null value, but an unbound variable (one that this context does not know about) should cause an {@link UnresolvableException} to be thrown.
