Remarks

Encapsulate Namespace logic for use by applications using SAX, or internally by SAX drivers.

This class encapsulates the logic of Namespace processing: it tracks the declarations currently in force for each context and automatically processes qualified XML names into their Namespace parts; it can also be used in reverse for generating XML qnames from Namespaces.

Namespace support objects are reusable, but the reset method must be invoked between each session.

Here is a simple session:

String parts[] = new String[3];
            NamespaceSupport support = new NamespaceSupport();

            support.pushContext();
            support.declarePrefix("", "http://www.w3.org/1999/xhtml");
            support.declarePrefix("dc", "http://www.purl.org/dc#");

            parts = support.processName("p", parts, false);
            System.out.println("Namespace URI: " + parts[0]);
            System.out.println("Local name: " + parts[1]);
            System.out.println("Raw name: " + parts[2]);

            parts = support.processName("dc:title", parts, false);
            System.out.println("Namespace URI: " + parts[0]);
            System.out.println("Local name: " + parts[1]);
            System.out.println("Raw name: " + parts[2]);

            support.popContext();

Note that this class is optimized for the use case where most elements do not contain Namespace declarations: if the same prefix/URI mapping is repeated for each context (for example), this class will be somewhat less efficient.

Although SAX drivers (parsers) may choose to use this class to implement namespace handling, they are not required to do so. Applications must track namespace information themselves if they want to use namespace information.

Added in SAX 2.0.
