| See <a href="http://www.saxproject.org">http://www.saxproject.org</a> |
| for further information. |
| <p> |
| 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. |
| <p> |
| Namespace support objects are reusable, but the reset method |
| must be invoked between each session. |
| <p>Here is a simple session:</p> |
| <pre><code> 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); |
| Console.WriteLine("Namespace URI: " + parts[0]); |
| Console.WriteLine("Local name: " + parts[1]); |
| Console.WriteLine("Raw name: " + parts[2]); |
| parts = support.ProcessName("dc:title", parts, false); |
| Console.WriteLine("Namespace URI: " + parts[0]); |
| Console.WriteLine("Local name: " + parts[1]); |
| Console.WriteLine("Raw name: " + parts[2]); |
| support.PopContext();</code></pre> |
| <p><p> |
| 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. |
| <p> |
| 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.</p> |
| </section> |
| <h4><a class="xref" href="Sax.Helpers.XMLFilter.html">XMLFilter</a></h4> |
| <section><p>Base class for deriving an XML filter. |
| <p> |
| <em>This module, both source code and documentation, is in the |
| Public Domain, and comes with <strong>NO WARRANTY</strong>.</em> |
| See <a href="http://www.saxproject.org">http://www.saxproject.org</a> |
| for further information. |
| <p> |
| This class is designed to sit between an <a class="xref" href="Sax.IXMLReader.html">IXMLReader</a> |
| and the client application's event handlers. By default, it |
| does nothing but pass requests up to the reader and events |
| on to the handlers unmodified, but subclasses can override |
| specific methods to modify the event stream or the configuration |
| requests as they pass through.</p> |
