Many NSXMLParsers in a singleview xcode - xcode4

Question

I have to parse two XML files in a singleview and so I m using two NSXMLParsers to get it.But he proble m is one parser is getting recognized and second parser is not getting recognized...I mean after the debugger passes this line [parser1 parse] it should go to the delegates didStartElement,foundcharacters and didEndElement but in my case the debugger is not entering those delegates.It is simply jumping to [parser1 release] stmnt.So those delegates are not getting recognized for parser1.Y is it so ?
I have written this :
NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:Url];
[parser setDelegate:self];
[parser setShouldProcessNamespaces:NO];
[parser setShouldReportNamespacePrefixes:NO];
[parser setShouldResolveExternalEntities:NO];
[parser parse];
[parser release];
NSXMLParser *parser1 = [[NSXMLParser alloc] initWithContentsOfURL:Url1];
[parser1 setDelegate:self];
[parser1 setShouldProcessNamespaces:NO];
[parser1 setShouldReportNamespacePrefixes:NO];
[parser1 setShouldResolveExternalEntities:NO];
[parser1 parse];
[parser1 release];
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if([elementName isEqualToString:#"TimeList"])
{
arr1=[[NSMutableArray alloc] init];
drr1=[[NSMutableDictionary alloc] init];
}
if([elementName isEqualToString:#"Company"])
{
drr1=[[NSMutableDictionary alloc] init];
}
srr1=[[NSMutableString alloc] init];
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
[srr1 appendString:string];
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if([elementName isEqualToString:#"ID"])
{
[drr1 setObject:srr1 forKey:#"ID"];
[srr1 release],srr1=nil;
return;
}
if([elementName isEqualToString:#"Company"])
{
[arr1 addObject:drr1];
}
if([elementName isEqualToString:#"TimeList"])
{
[drr1 release];
}
[srr1 release],srr1=nil;
}
- (void)parser1:(NSXMLParser *)parser1 didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if([elementName isEqualToString:#"categorylist"])
{
arr2=[[NSMutableArray alloc] init];
drr2=[[NSMutableDictionary alloc] init];
}
if([elementName isEqualToString:#"lookup"])
{
drr2=[[NSMutableDictionary alloc] init];
}
srr2=[[NSMutableString alloc] init];
}
-(void)parser1:(NSXMLParser *)parser1 foundCharacters:(NSString *)string{
[srr2 appendString:string];
}
- (void)parser1:(NSXMLParser *)parser1 didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if([elementName isEqualToString:#"Code"])
{
[drr2 setObject:srr2 forKey:#"Code"];
[srr2 release],srr2=nil;
return;
}
if([elementName isEqualToString:#"lookup"])
{
[arr2 addObject:drr2];
}
if([elementName isEqualToString:#"categorylist"])
{
[drr2 release];
}
[srr2 release],srr2=nil;
}
The first parser is getting recognized and getting the data.But for the second parser didStartElement is not getting recognized...What could be the possible reason ?

I solved it by myself.Actually I declared a string and passed some value to it.While parsing it checks ,if that condition gets true then it parses ..
This is what I did:
NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:Url];
[parser setDelegate:self];
[parser setShouldProcessNamespaces:NO];
[parser setShouldReportNamespacePrefixes:NO];
[parser setShouldResolveExternalEntities:NO];
currentparser=#"1";
[parser parse];
[parser release];
NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:Url1];
[parser setDelegate:self];
[parser setShouldProcessNamespaces:NO];
[parser setShouldReportNamespacePrefixes:NO];
[parser setShouldResolveExternalEntities:NO];
currentparser=#"2";
[parser parse];
[parser release];
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if(currentparser==#"1")
{
//do something
}
if(currentparser=#"2")
{
//do something
}
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{
if(currentparser==#"1")
{
//do something
}
if(currentparser=#"2")
{
//do something
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
if(currentparser==#"1")
{
//do something
}
if(currentparser=#"2")
{
//do something
}
}
