public class Context
extends java.lang.Object
implements java.lang.Cloneable
```
The context for a node contains:
- elementStack - the stack with ContextElement up to the root. These represent the ancestors of the element for which the Context was built.
- previousSiblingElements - the list with the ContextElement representing the siblings of the element for which the Context was built.
- proxyNamespaceMapping - The mapping between namespace prefixes and URI's to the point where the Context was built.

    Executes an XPath 2.0 expression over a simplified version of the entire document, containing no text nodes for faster processing. The XML Reader over which the XPath is run does not contain any text nodes so this method is useful only for gathering attribute values which adhere to certain conditions (like //@id).
    
    Parameters:
    
    expression - The XPath expression to be executed.
    
    prefixNamespaceMappings - An array of prefixes followed by namespace URI's representing the namespace mappings to the point of the Context.
    Example:
    {"xsl", "http://www.w3.org/1999/XSL/Transform", "xsd", "http://www.w3.org/2001/XMLSchema"}
    
    Returns:
    
    A list of strings representing the XPath results, never null.

                                   boolean useFullDocumentContent)
```
    Executes an XPath 2.0 expression over the current document.
