## Uses of Class
org.apache.xpath.XPathVisitor

- Packages that use XPathVisitor
  Package | Description
  --- | ---
  org.apache.xalan.extensions | Implementation of Xalan Extension Mechanism.
  org.apache.xalan.templates | Implements the `Templates` interface, and defines a set of classes that represent an XSLT stylesheet.
  org.apache.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.apache.xpath.axes | Implementation of XPath LocationPath support -- primary classes are LocPathIterator and UnionPathIterator.
  org.apache.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.apache.xpath.objects | Implementation of XPath polymorphic type objects -- this package will grow as XPath objects are expanded to support XML Schema data types.
  org.apache.xpath.operations | Support for XPath operations, such as +, -, string(), etc.
  org.apache.xpath.patterns | Implementation of XPath nodeTest support, and XSLT pattern matching support.

- - ### Uses of XPathVisitor in org.apache.xalan.extensions

    Subclasses of XPathVisitor in org.apache.xalan.extensions
    Modifier and Type | Class and Description
    --- | ---
    `class` | `ExpressionVisitor` When `StylesheetHandler` creates an `XPath`, the ExpressionVisitor visits the XPath expression.

  - ### Uses of XPathVisitor in org.apache.xalan.templates

    Subclasses of XPathVisitor in org.apache.xalan.templates
    Modifier and Type | Class and Description
    --- | ---
    `class` | `AbsPathChecker` This class runs over a path expression that is assumed to be absolute, and checks for variables and the like that may make it context dependent.
    `class` | `RedundentExprEliminator` This class eleminates redundent XPaths from a given subtree, and also collects all absolute paths within the subtree.
    `class` | `VarNameCollector` This class visits variable refs in an XPath and collects their QNames.
    `class` | `XSLTVisitor` A derivation from this class can be passed to a class that implements the XSLTVisitable interface, to have the appropriate method called for each component of an XSLT stylesheet.
