Using Treeviewer Bean (XMLTreeView() API)

The Treeviewer Bean shows an XML document as a tree. It recognizes the following XML DOM nodes:

• Tag

• Attribute Name

• Attribute Value

• Comment

• CDATA

• PCDATA

• PI Data

• PI Name

• NOTATION Symbol

It takes as input an org.w3c.dom.Document object.

Figure 20-3 illustrates the XML Tree Viewer Bean usage.

A DOM XML document is input to the XMLTreeView.setXMLDocument(doc) method. This associates the XML Tree Viewer with the XML document.

Available TreeViewer Bean methods are:

• getPreferredSize() -- Returns the XMLTreeView preferred size.

• setXMLDocument(Document) -- Associates the XMLTreeViewer with an XML document.

• updateUI() -- Forces the XMLTreeView to update/refresh the user interface.
