org.htmlunit.xpath.ExpressionNode

Packages that use ExpressionNode

Package	Description
org.htmlunit.xpath	Implementation of XPath; for the most part, only classes meant for public use are found at this root level of the XPath packages.
org.htmlunit.xpath.axes	Implementation of XPath LocationPath support -- primary classes are LocPathIterator and UnionPathIterator.
org.htmlunit.xpath.functions	Implements XPath functions -- each function is derived from Function, FunctionOneArg, Function2Args, etc, with number-of-arguments checking being applied mainly at compile time -- this package only implements XPath functions, XSLT functions are found in the "templates" package.
org.htmlunit.xpath.objects	Implementation of XPath polymorphic type objects -- this package will grow as XPath objects are expanded to support XML Schema data types.
org.htmlunit.xpath.operations	Support for XPath operations, such as +, -, string(), etc.
org.htmlunit.xpath.patterns	Implementation of XPath nodeTest support, and XSLT pattern matching support.
