iPhone: How to access multiple XMLs in the same view - iphone

Question

I am trying to read data from two different XML's to populate fields of my View in iPhone.
Is there any way to read multiple XML's in the same view? I can read and parse a single XML.
Thanks

Use a Boolean, name it isParsingNextString to parse a different string and elements.
//in viewDidLoad
isParsingNextString = NO;
//put this inside your begin parsing method
if (isParsingNextString == NO) {
//parse 1st string URL
}
if (isParsingNextString == YES) {
//parse 2nd string URL
}
//when your document finishes set the bool to yes
//now restart your parser inside an if statement so you dont have a parsing loop
if(isParsingNextString == NO) {
isParsingNextString = YES;
[self parseXML];
}
