public class XMLTableContentProvider
extends SelectableListTableContentProvider

Table provider which displays a list of W3C DOM Nodes. If this provider is configured with a rows xpath expression (see setRowsXpath(String)), the xpath expression should resolve to a list of elements to display. If this provider is not configured with a rows xpath expression, the child elements of the root node will be displayed.
