I have an NSXMLParser
, which is parsing an XML file, using Apple's implementation of event-driven XML handling.
I have it setup correctly, but when I get to the actual parsing, it goes over the same element twice as it parses through.
My code looks like this:
AppDelegate *myApp = (AppDelegate*)[[UIApplication sharedApplication] delegate];
NSData *tempData = [myApp.stringDetails dataUsingEncoding:NSUTF8StringEncoding];
NSString *textFields = [NSString string];
NSXMLParser *parser = [[NSXMLParser alloc]initWithData:tempData];
[parser setDelegate: self];
if ([parser parse]!= YES) {
NSLog(@"%@", parser.parserError.description);
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict {
textFields = elementName;
}
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
if ([textFields isEqualToString:@"firstName"]) {
[firstName setText:string];
NSLog(@"first name is %@", string);
return;
}
if ([textFields isEqualToString:@"lastName"]) {
[lastName setText:string];
NSLog(@"last name is %@", string);
return;
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName {
return;
}
The XML document i'm parsing looks like this:
<details>
<firstName>tester</firstName>
<lastName>testingson</lastName>
<address>
<street1>123 Main St.</street1>
<street2></street2>
<city>Anywhere</city>
<state>BC</state>
<country></country>
<postalCode>A0A0B0</postalCode>
</address>
<company>TEST</company>
<email>testing@test.com</email>
<cabbieNo>TEST</cabbieNo>
<driversLicense>TEST</driversLicense>
<plateNo>TEST</plateNo>
<services>
<taxi>1</taxi>
<ladies>1</ladies>
<limo>1</limo>
<handicap>1</handicap>
</services>
</details>
Strangely, my debug logs like this:
2012-10-01 15:36:35.742 myAPP[9974:c07] first name is tester
2012-10-01 15:36:35.743 myAPP[9974:c07] first name is
2012-10-01 15:36:35.743 myAPP[9974:c07] last name is testingson
2012-10-01 15:36:35.744 myAPP9974:c07] last name is
As you can see, it looks through each element twice, but then on the second time, string
is empty (which shouldn't happen..in fact there shouldn't even be a second foundCharacters
event). Do you guys have any idea why?
Thanks!
You should get your Element result in didEndElement
Here is example
In - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
You should append string(found characters) eg:
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {
if (!currentStringValue) {
// currentStringValue is an NSMutableString instance variable
currentStringValue = [[NSMutableString alloc] initWithCapacity:50];
}
[currentStringValue appendString:string];
}
Hope this will be helpful to you.
