如何使用NSxml解析器解析iPhone中的多个xml文件

Question

I have nearly 15 and more xml file inside of one folder if possible to parse all file one by one? I set path like this below if I want to parse multiple files. how can I set path of that folder file?

this code for single file xml parser it's working fine.

NSString *playlistfilePath = [[NSBundle mainBundle] pathForResource:@"CT8OkzhF8qmEYGe2" ofType:@"xml"];  
NSData *playlistfileData = [NSData dataWithContentsOfFile:playlistfilePath]; 
NSString *playlistxmlFile = [[NSString alloc] initWithData:playlistfileData encoding:NSASCIIStringEncoding];

//parsing the XML
PlaylistXmlParser *playlistparser = [[PlaylistXmlParser alloc] init];
[playlistparser parseXMLFile:playlistxmlFile];

that all the XML files are having same structure and same element.

On the basis of the NSXMLParser object write the logic of the parsing:-

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
        //check with switch or if else condition which NSXMLParser object is using this delegate.
}

As like above all the delegates of NSXMLParser have a parameter as an NSXMLParser object.

try this:

NSXMLParser *xmlParser = [[[NSXMLParser alloc] initWithData:playlistfileData]autorelease];

PlaylistXmlParser *parser = [[PlaylistXmlParser alloc] initXMLParser:@"xmlname"];
[xmlParser setDelegate:parser];

in PlaylistXmlParser.m file

- (PlaylistXmlParser *) initXMLParser:(NSString *)name {

[super init];
xmlname =name;

return self;

}

now in every methods in PlaylistXmlParser.m file  :

if  ([xmlname isEqualToString:@"xmlname"]) {
    //store  data 
}
else if([xmlname isEqualToString:@"xmlname_1"]){
   //store  data 

}

@moorthy use pathForResourcesType:inDirectory on NSBundle method to get array of paths, Then for every single path inside the array create an instance for the parser class and parse the file. [[NSBundle mainbundle]pathForResourcesType:@"xml" inDirectory:"Your directory Path"]
This will return an array ...... Hope it helps you
