New in SAX2, defined in helpers/NamespaceSupport
32
Encapsulate Namespace logic for use by SAX drivers.
34
This class encapsulates the logic of Namespace processing: it tracks
35
the declarations currently in force for each context and automatically
36
processing raw XML 1.0 names into their Namespace parts.
38
Namespace support objects are reusable, but the reset method must be
39
invoked between each session.
41
Here is a simple session:
43
String parts[] = new String[3];
44
SaxNamespaceSupport support;
46
support = [[SaxNamespaceSupport alloc] init];
48
[support pushContext];
49
[support declarePrefix:@"" uri:@"http://www.w3.org/1999/xhtml"];
50
[support declarePrefix:@"dc" uri:@"http://www.purl.org/dc#"];
52
String parts[] = support.processName("p", parts, false);
53
System.out.println("Namespace URI: " + parts[0]);
54
System.out.println("Local name: " + parts[1]);
55
System.out.println("Raw name: " + parts[2]);
57
String parts[] = support.processName("dc:title", parts, false);
58
System.out.println("Namespace URI: " + parts[0]);
59
System.out.println("Local name: " + parts[1]);
60
System.out.println("Raw name: " + parts[2]);
64
Note that this class is optimized for the use case where most elements
65
do not contain Namespace declarations: if the same prefix/URI mapping
66
is repeated for each context (for example), this class will be somewhat

extern NSString *SaxXMLNS;

@interface SaxNamespaceSupport : NSObject

/* start a new ns context */
80
/* revert to previous ns context */

/* Declare a Namespace prefix. */
84
- (BOOL)declarePrefix:(NSString *)_prefix uri:(NSString *)_uri;
86
/* Return an enumeration of all prefixes declared in this context. */
87
- (NSEnumerator *)prefixEnumerator;

/* Look up a prefix and get the currently-mapped Namespace URI. */
90
- (NSString *)getUriForPrefix:(NSString *)_prefix;

/* Reset this Namespace support object for reuse. */
96
Process a raw XML 1.0 name.
98
This method processes a raw XML 1.0 name in the current context by
99
removing the prefix and looking it up among the prefixes currently
100
declared. The return value will be the array supplied by the caller,
101
filled in as follows:
103
parts[0] The Namespace URI, or an empty string if none is in use.
104
parts[1] The local name (without prefix).
105
parts[2] The original raw name.
107
All of the strings in the array will be internalized. If the raw name
108
has a prefix that has not been declared, then the return value will be
111
Note that attribute names are processed differently than element names:
112
an unprefixed element name will received the default Namespace (if any),
113
while an unprefixed element name will not.
