objective-c - 使用 XMLParser 访问正确的 XML 节点

Question

我无法访问 XML 的节点:

<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <array>
      <dict>
        <key>cnt_id</key>
        <string>lovenyc</string>
        <key>user</key>
        <string></string>
        <key>emps_cnpj</key>
        <string>11379404000154</string>
        <key>depto_id</key>
        <string>0</string>
        <key>id_device</key>
        <string>7543AF5F-495D-4739-BB83-56BF08CE7DF0</string>
        <key>data_acesso</key>
        <string>2013-01-04 12:48:21</string>
        <key>id_usuario</key>
        <string></string>
        <key>user_fav</key>
        <string>0</string>
        <key>user_like</key>
        <string>0</string>
        <key>user_lat</key>
        <string></string>
      </dict>
    </array>
 </plist>

objective-c 代码:

-(void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)
namespaceURI qualifiedName:(NSString *) qName attributes:(NSDictionary *)attributeDict
{
    NSMutableDictionary * dict = [[NSMutableDictionary alloc]init];
    _xmlObjects = [[NSMutableArray alloc]init];

    NSLog(@"Attribute %@",[attributeDict allKeys]);
    NSLog(@"Attribute Values %@",[attributeDict allValues]);
}

日志总是给我空值，我无法访问 <string>值(value)例如，有什么建议吗？谢谢

使用 Foundation 对象解析属性列表是一项简单的单行任务:

NSArray *array = [NSArray arrayWithContentsOfFile:@"PropList.plist"];

更多信息在 documentation .

(请注意，您必须使用正确的类 - 如果属性列表的根对象是 <dict>，那么您应该改用 + [NSDictionary dictionaryWithContentsOfFile:]。)
