New in SAX2, defined in helpers/NamespaceSupport
Encapsulate Namespace logic for use by SAX drivers.
This class encapsulates the logic of Namespace processing: it tracks
the declarations currently in force for each context and automatically
processing raw XML 1.0 names into their Namespace parts.
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];
SaxNamespaceSupport support;
support = [[SaxNamespaceSupport alloc] init];
[support pushContext];
[support declarePrefix:@"" uri:@"http://www.w3.org/1999/xhtml"];
[support declarePrefix:@"dc" uri:@"http://www.purl.org/dc#"];
String 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]);
String 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.

Process a raw XML 1.0 name.
This method processes a raw XML 1.0 name in the current context by
removing the prefix and looking it up among the prefixes currently
declared. The return value will be the array supplied by the caller,
filled in as follows:
parts[0] The Namespace URI, or an empty string if none is in use.
parts[1] The local name (without prefix).
parts[2] The original raw name.
All of the strings in the array will be internalized. If the raw name
has a prefix that has not been declared, then the return value will be
null.
Note that attribute names are processed differently than element names:
an unprefixed element name will received the default Namespace (if any),
while an unprefixed element name will not.
