org.apache.commons.jxpath.xml.DocumentContainer
public class DocumentContainer
An XML document container reads and parses XML only when it is accessed. JXPath traverses Containers transparently - you use the same paths to access objects in containers as you do to access those objects directly. You can create XMLDocumentContainers for various XML documents that may or may not be accessed by XPaths. If they are, they will be automatically read, parsed and traversed. If they are not - they won't be read at all.
