[pre]<?xml version="1.0" encoding="UTF-8"?> <users>     <user name="hoge" age="20" />     <user name="fuga" age="30" /> </users>[/pre][pre]代码如下：[/pre][pre] [pre]static NSString *feedURLString = @"http://www.yifeiyang.net/test/test.xml"; - (void)parserDidStartDocument:(NSXMLParser *)parser {     // 解析开始时的处理 } - (void)parseXMLFileAtURL:(NSURL *)URL parseError:(NSError **)error {     NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:URL];     [parser setDelegate:self];     [parser setShouldProcessNamespaces:NO];     [parser setShouldReportNamespacePrefixes:NO];     [parser setShouldResolveExternalEntities:NO];     [parser parse];     NSError *parseError = [parser parserError];     if (parseError && error) {         *error = parseError;     }     [parser release]; }[/pre][pre]- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:[/pre][pre](NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {    // 元素开始句柄     if (qName) {         elementName = qName;     }     if ([elementName isEqualToString:@"user"]) {         // 输出属性值         NSLog(@"Name is %@ , Age is %@", [attributeDict objectForKey:@"name"], [attributeDict objectForKey:@"age"]);     } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:[/pre][pre](NSString *)namespaceURI qualifiedName:(NSString *)qName {     // 元素终了句柄     if (qName) {         elementName = qName;     } } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {     // 取得元素的text } NSError *parseError = nil; [self parseXMLFileAtURL:[NSURL URLWithString:feedURLString] parseError:&parseError];[/pre] [/pre]
