Examples of net.sf.saxon.s9api.XdmDestination

net.sf.saxon.s9api.XdmDestination
An XdmDestination is a {@link Destination} in which an {@link XdmNode}is constructed to hold the output of a query or transformation: that is, a tree using Saxon's implementation of the XDM data model
No data needs to be supplied to the XdmDestination object. The query or transformation populates an XdmNode, which may then be retrieved using the getXdmNode method.

An XdmDestination is designed to hold a single document. It should therefore not be used as the destination of a query that produces multiple documents. If multiple documents are sent to an XdmDestination, the getXdmNode method will return the last one.

An XdmDestination can be reused to hold the results of a second query or transformation only if the {@link #reset} method is first called to reset its state.

                    if (((XdmNode) nodes.get(pos)).getNodeKind() == XdmNodeKind.ELEMENT) {
                        node = (XdmNode) nodes.get(pos);
                    }
                }


                XdmDestination dest = new XdmDestination();
                try {
                    S9apiUtils.writeXdmValue(cfgProcessor, nodes, dest, node.getBaseURI());
                    doc = dest.getXdmNode();
                    if (excludeUris.size() != 0) {
                        doc = S9apiUtils.removeNamespaces(cfgProcessor, doc, excludeUris, true);
                    }
