This class adds an entrypoint into XPath functionality,
for Anakia.
All methods take a string XPath specification, along with
a context, and produces a resulting java.util.List.
The W3C XPath Specification (http://www.w3.org/TR/xpath) refers
to NodeSets repeatedly, but this implementation simply uses
java.util.List to hold all Nodes. A 'Node' is any object in
a JDOM object tree, such as an org.jdom.Element, org.jdom.Document,
or org.jdom.Attribute.

To use it in Velocity, do this:
#set $authors = $xpath.applyTo("document/author", $root) #foreach ($author in $authors) $author.getValue() #end #set $chapterTitles = $xpath.applyTo("document/chapter/@title", $root) #foreach ($title in $chapterTitles) $title.getValue() #endIn newer Anakia builds, this class is obsoleted in favor of calling
selectNodes()on the element directly:#set $authors = $root.selectNodes("document/author") #foreach ($author in $authors) $author.getValue() #end #set $chapterTitles = $root.selectNodes("document/chapter/@title") #foreach ($title in $chapterTitles) $title.getValue() #end
