I think, try NSXMLParser

you use best way of read xml file with TouchXML ....and for TouchXML use this bellow link

http://dblog.com.au/general/iphone-sdk-tutorial-building-an-advanced-rss ...

also here when you get response then other way you can read like bellow using TouchXML.. ie..

- (void) fetchDataSuccessforEvent:(NSMutableData *)data
{
    CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:data options:0 error:nil] autorelease];
    NSArray *nodes = [doc nodesForXPath:@"//Table" error:nil];

    for (CXMLElement *node in nodes) 
    {


        for(int counter = 0; counter < [node childCount]; counter++) 
        {
            if ([[[node childAtIndex:counter] name] isEqualToString:@"Column1"]) 
            {
                NSString *string = [[node childAtIndex:counter] stringValue];
                                NSLog(@"\n\n Title %@",string);

            }

        }


    }

}

so easy... hope,this help you.... :)

This is not a parsing problem. Check the web service and make sure that xml header is: <?xml version="1.0" encoding="utf-8"?> or something like this.
