  • Method Details

    • getRootExpr

      Expr getRootExpr()
      Returns the wrapped expression object.
      Returns:
      the wrapped Expr object

    • setRootExpr

      void setRootExpr(Expr rootExpr)
      Changes the wrapped expression object.
      Parameters:
      rootExpr - the new expression object to wrap

    • getText

      String getText()
      Returns a String containing the XPath expression.
      Returns:
      the text form of this XPath expression

    • simplify

      void simplify()
      Simplifies the XPath expression. For example, the expression //para[1 = 1] could be simplified to //para. In practice, this is usually a noop. Jaxen does not currently perform any simplification.

    • asList
