How to parse a locally stored XML file in iPhone?
please help me with this using code snippets

Answer 1

I have used NSXMLParser and i achieved it. I have r.xml file in my resource. I have just parsing the title and displayed using NSXMLParser.
r.xml:
<rss>
<eletitle > My Xml Program </eletitle>
</rss>
Here my sample code is,
#interface:
NSXMLParser *rssparser;
NSMutableArray *stories;
NSMutableDictionary *item;
NSMutableString *currrentTitle;
NSString *currentElement;
#implementation:
-(void) viewDidAppear:(BOOL) animated
{
[self parseXMLFileAtURL];
}
-(void) parseXMLFileAtURL
{
stories = [[NSMutableArray alloc] init];
NSURL *xmlURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"r" ofType:#"xml"]];
rssparser = [[NSXMLParser alloc] initWithContentsOfURL:xmlURL];
[rssparser setDelegate:self];
[rssparser setShouldProcessNamespaces:NO];
[rssparser setShouldReportNamespacePrefixes:NO];
[rssparser setShouldResolveExternalEntities:NO];
[rssparser parse];
}
- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{
currentElement = [elementName copy];
if([elementName isEqualToString:#"rss"]);
{
item = [[NSMutableDictionary alloc] init];
currrentTitle = [[NSMutableString alloc] init];
}
}
-(void) parser:(NSXMLParser *)parser foundCharacters:(NSString *) string
{
if([currentElement isEqualToString:#"eletitle"])
{
[currrentTitle appendString:string];
}
}
- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{
if([elementName isEqualToString:#"rss"])
{
[item setObject:currrentTitle forKey:#"eletitle"];
[stories addObject:[item copy]];
}
}
- (void)parserDidEndDocument:(NSXMLParser *)parser
{
NSLog(#"The currrentTitle is %#",currrentTitle);
}
Best of Luck.

I'm sorry I cannot give you any snippet now, but in one project I did some time ago, we used the touchXML library.
http://code.google.com/p/touchcode/wiki/TouchXML
With this, parsing XML was pretty easy.
Good luck!
