Class XPathForeachDirective

java.lang.Object
  org.apache.velocity.runtime.directive.Directive
      no.sesat.search.view.velocity.AbstractDirective
          no.sesat.search.view.velocity.XPathForeachDirective

All Implemented Interfaces:

Cloneable, org.apache.velocity.runtime.directive.DirectiveConstants

public class XPathForeachDirective
extends AbstractDirective

Directive for moving through w3c dom node lists selected by an XPath expression. Example:

 #publish("/pages/xmlbase/cat.xml")
 #xpathforeach($item "/categories/item[greatprnt=33]")
   #xpath("catname" $item)
 #end
 

By default, the expression is applied to the value of the context variable "document". If there is a third argument the expression is applied to the value this argument instead. The argument should be a type of org.w3c.dom.Node.
