You want to do something like this?

Have a flag variable of any type. Let us consider the flag variable is NSString. And you are going to parse two XML files. Consider, one XML is for listing items and another one is for detail view.

Before you parse the first XML (the XML for list, in our case) you set the flag something like this,

NSString *xmlContentFlag = @"List";

Then, before you parse the second XML (the XML for detail) you set the flag something like this,

NSString *xmlContentFlag = @"Detail";

In your parser methods, do the following,

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 
    namespaceURI:(NSString *) namespaceURI qualifiedName:(NSString *)qName
    attributes: (NSDictionary *)attributeDict {

    if ([xmlContentFlag isEqualToString:@"List"]) {

        // your code here

    } else if ([xmlContentFlag isEqualToString:@"Detail"]) {

        // your code here
    }
}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {

    if ([xmlContentFlag isEqualToString:@"List"]) {

        // your code here

    } else if ([xmlContentFlag isEqualToString:@"Detail"]) {

        // your code here
    }
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName 
    namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {

    if ([xmlContentFlag isEqualToString:@"List"]) {

        // your code here

    } else if ([xmlContentFlag isEqualToString:@"Detail"]) {

        // your code here
    }
 }

Note: You can have the flag to be of any type, not necessarily NSString.

I hope this is what you expect.
