Examples of org.apache.jasper.xmlparser.TreeNode

org.apache.jasper.xmlparser.TreeNode
Simplified implementation of a Node from a Document Object Model (DOM) parse of an XML document. This class is used to represent a DOM tree so that the XML parser's implementation of org.w3c.dom need not be visible to the remainder of Jasper.
