Constructor Details

TracerEvent

public TracerEvent(TransformerImpl processor,
                   Node sourceNode,
                   QName mode,
                   ElemTemplateElement styleNode)
Create an event originating at the given node of the style tree.
Parameters:
processor - The XSLT TransformerFactory.
sourceNode - The current context node.
mode - The current mode.
styleNode - The stylesheet element that is executing.

Method Details

printNode

public static String printNode(Node n)
Returns a string representation of the node. The string returned for elements will contain the element name and any attributes enclosed in angle brackets. The string returned for attributes will be of form, "name=value."
Parameters:
n - any DOM node. Must not be null.
Returns:
a string representation of the given node.

printNodeList

public static String printNodeList(NodeList l)
Returns a string representation of the node list. The string will contain the list of nodes inside square braces. Elements will contain the element name and any attributes enclosed in angle brackets. Attributes will be of form, "name=value."
Parameters:
l - any DOM node list. Must not be null.
Returns:
a string representation of the given node list.
