Interface Summary
LastPositionFinder A LastPositionFinder is an object used by the Context to locate the last position in the context node list.
StaticContext A StaticContext contains the information needed while an expression or pattern is being parsed.
 

Class Summary
AttributeValueTemplate This class represents an attribute value template.
BooleanValue A boolean XPath value
ContextNodeExpression This class represents the expression ".", which always returns the context node.
DifferenceEnumeration An enumeration representing a nodeset that is an intersection of two other NodeSets.
DistinctEnumeration An enumeration returning the distinct nodes from a supplied nodeset
EmptyNodeSet A node-set value no nodes
ErrorExpression Error expression: this expression is generated when the supplied expression cannot be parsed, and the containing element enables forwards-compatible processing.
Expression This class serves two purposes: it is an abstract superclass for different kinds of XPath expression, and it contains a static method to invoke the expression parser
ExpressionParser Parser for XSL expressions and patterns.
FilterEnumerator A FilterEnumerator filters an input NodeEnumeration using a filter expression.
FragmentValue This class represents a Value of type result tree fragment.
Function Abstract superclass for system-defined and user-defined functions
FunctionProxy This class acts as a proxy for an extension function defined as a method in a user-defined class
IntersectionEnumeration An enumeration representing a nodeset that is an intersection of two other NodeSets.
IsLastExpression position()=last() expression
LookaheadEnumerator A LookaheadEnumerator passes the nodes from a base enumerator throgh unchanged.
NodeListExpression A NodeListExpression is an expression denoting a set of nodes sorted in document order.
NodeSetComparison NodeSetComparison: A Relational Expression that compares a node-set with a string or numeric value for equals, not-equals, greater-than or less-than.
NodeSetExpression A NodeSetExpression is any expression denoting a set of nodes.
NodeSetExtent A node-set value implemented extensionally.
NodeSetIntent A node-set value implemented intensionally.
NodeSetValue A node-set value.
NumericValue A numeric (floating point) value
ObjectValue An XPath value that encapsulates a Java object.
ParentNodeExpression Class ParentNodeExpression represents the XPath expression ".." or "parent::node()"
PathExpression An expression that establishes a set of nodes by following relationships between nodes in the document.
RootExpression An expression whose value is always a set of nodes containing a single node, the document root.
SingletonComparison Singleton Comparison: A Relational Expression that compares a singleton node-set with a string or numeric value for equals, not-equals, greater-than or less-than.
SingletonExpression A node set expression that will always return zero or one nodes
SingletonNodeSet A node-set value containing zero or one nodes
SortedSelection A NodeSetExpression that retrieves nodes in order according to a specified sort key.
SortKeyEnumeration A SortKeyEnumeration is NodeEnumeration that delivers the nodes sorted according to a specified sort key.
StandaloneContext A StandaloneContext provides a context for parsing an expression or pattern appearing in a context other than a stylesheet.
Step A step in a path expression
StringValue A string value
StyleSheetFunctionCall This class represents a call to a function defined in the stylesheet
TextFragmentValue This class represents a Value of type result tree fragment, specifically, an RTF whose root owns a single text node.
UnionEnumeration An enumeration representing a nodeset that is a union of two other NodeSets.
Value A value is the result of an expression but it is also an expression in its own right
VariableReference Variable reference: a reference to an XSL variable
 

Exception Summary
XPathException XPathException is used to indicate an error in an XPath expression.
