Here is one way (assuming you already know how to use NSXMLParser)

xml:

<intVariable>10</intVariable>

code:

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string 
{
    if(!currentElementValue)
        currentElementValue = [[NSMutableString alloc] initWithString:string];
    else
        [currentElementValue appendString:string];
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName
  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName
    attributes:(NSDictionary *)attributeDict 
{
     if ([elementName isEqualToString:@"intVariable"])
        intVariable = [currentElementValue intValue];

     [currentElementValue release];
     currentElementValue = nil;
}

(currentElementValue and intVariable are mutable string and int members respectively).
