public class PageDataImpl
extends javax.servlet.jsp.tagext.PageData
implements TagConstants

An implementation of javax.servlet.jsp.tagext.PageData which builds the XML view of a given page. The XML view is built in two passes: During the first pass, the FirstPassVisitor collects the attributes of the top-level jsp:root and those of the jsp:root elements of any included pages, and adds them to the jsp:root element of the XML view. In addition, any taglib directives are converted into xmlns: attributes and added to the jsp:root element of the XML view. This pass ignores any nodes other than JspRoot and TaglibDirective. During the second pass, the SecondPassVisitor produces the XML view, using the combined jsp:root attributes determined in the first pass and any remaining pages nodes (this pass ignores any JspRoot and TaglibDirective nodes).
