任何人都可以帮助我如何解析这些数据。由于我是解析新手，请任何人帮助我。
<?xml version="1.0" encoding="UTF-8"?>
<Tricon Type="Login">
<Result>Invalid_Email_Password</Result>
</Tricon>
我的解析器代码是
#import "ResponseXmlParser.h"
@implementation ResponseXmlParser
@synthesize myParser;
-(void)parserDidStartDocument:(NSXMLParser *)parser
{
printf("\n This is in parserDidStartDocument");
response = @"";
type = @"";
}
ParseXMLFileWithData 方法
-(void)parseXMLFileWithData:(NSData*)data
{
isRootNode = NO;
isResponse=NO;
myParser = [[NSXMLParser alloc] initWithData:data];
[myParser setDelegate:self];
[myParser setShouldProcessNamespaces:NO];
[myParser setShouldReportNamespacePrefixes:NO];
[myParser setShouldResolveExternalEntities:NO];
[myParser parse];
[myParser release];
}
didStartElement 方法
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI: (NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
printf("\n This is in didStartElement");
if (qName)
{
elementName = qName;
}
if([elementName isEqualToString:@"Tricon"])
{
printf("\n This is in didStartElement Tricon");
if(responseObj != nil)
{
[responseObj release];
}
responseObj = [[Response alloc] init] ;
isRootNode= YES;
isResponse=NO;
response=@"";
type = @"";
type=(NSString*)[attributeDict objectForKey:@"Type"];
}
if([elementName isEqualToString:@"Result"])
{
printf("\n This is in didStartElement Result");
isResponse = YES;
}
}
didEndElement 方法
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
printf("\n This is in didEndElement Result");
if (qName)
{
elementName = qName;
}
if([elementName isEqualToString:@"Result"])
{
printf("\n the element name is :%s",[elementName UTF8String]);
printf("\n the element name is :%s",[response UTF8String]);
[responseObj setResponse:response];
printf("\n the element name is :%s",[responseObj.response UTF8String]);
isResponse=NO;
}
if([elementName isEqualToString:@"Tricon"])
{
isRootNode = NO;
responseObj.type = type;
printf("\n The type is :%s\n",[responseObj.type UTF8String]);
}
}
foundCharacters 方法
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
printf("\n This is in foundCharacters ");
if(isRootNode == YES)
{
if(isResponse == YES )
{
string = [string stringByReplacingOccurrencesOfString:@"\n" withString:@" "];
string = [string stringByReplacingOccurrencesOfString:@"\t" withString:@" "];
string = [string stringByReplacingOccurrencesOfString:@" " withString:@" "];
string = [string stringByReplacingOccurrencesOfString:@" " withString:@" "];
string = [string stringByReplacingOccurrencesOfString:@" " withString:@"\n\n\t"];
string = [string stringByReplacingOccurrencesOfString:@"<p>" withString:@""];
string = [string stringByReplacingOccurrencesOfString:@"</p>" withString:@"\n"];
}
if(isResponse == YES)
{
response = [response stringByAppendingString:string];
}
}
}
parserDidEndDocument 方法 - (void)parserDidEndDocument:(NSXMLParser *)parser { printf("\n This is in parserDidEndDocument ");
}
我在这里返回对象
-(Response*)getMessageFromResponseParser
{
printf("\n the response value is :%s\n",[responseObj.response UTF8String]);
return responseObj;
}
-(void)dealloc
{
[responseObj release];
[super dealloc];
}
