Constructor Detail

CopyProcessor

public CopyProcessor(java.lang.String query,
                     java.lang.String destination,
                     java.lang.String attribute)

Parameters:

query - Bellows query path to select the source node(s)

destination - Bellows query path to select the destination node(s)

attribute - optional attribute name

Method Detail

getDestinationNodes

protected org.writersforge.bellows.Datum[] getDestinationNodes(org.writersforge.bellows.Datum datum)

Finds the Datum nodes to perform the transformation on.

Parameters:

datum - the input datum tree to select nodes from

Returns:

the nodes to operate on

transformNode

protected void transformNode(org.writersforge.bellows.Datum node,
                             org.writersforge.bellows.Datum root)

Performs an in-place transformation on the supplied Datum tree.

Specified by:

transformNode in class XFormProcessor

Parameters:

node - the current node to operate upon

root - the root of the entire XML tree
