org.htmlunit.xpath.Expression
-
Packages that use Expression 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.compiler Implements an XPath parser which produces an OpMap, and a so-called Compiler which produces an expression tree for fast evaluation.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. -
