Parsing subnode with TouchXML - objective-c

Question

I'm using TouchXML to parse my RSS.
The new XML
<channel>
<item>
<title> </title>
<social>
<views>
<total_views>2</total_views>
</views>
<reviews>
<average_rating>2</average_rating>
</reviews>
</social>
</item>
</channel>
I currently parsing the XML and passing it with initWithData to my detail view for the title of the article like this:
[rssData objectForKey: #"title" ];
But how do I show the value of stars its a subnode of rate and rate is a subnode from social?
I have tried this: [rssData objectForKey: #"social/rate/stars" ];
But it won't work. Please tell me how.

Answer 1

The entire premise that I based my original answers seem to be wrong. If you've used the following snippet,
for (CXMLElement *node in nodes) {
NSMutableDictionary *item = [[NSMutableDictionary alloc] init];
int counter;
for(counter = 0; counter < [node childCount]; counter++) {
// common procedure: dictionary with keys/values from XML node
[item setObject:[[node childAtIndex:counter] stringValue] forKey:[[node childAtIndex:counter] name]];
}
[results addObject:item];
[item release];
}
to generate your code than children of social element are stored as a string value and any reasonable means to extract them are lost. I would suggest that you store the nodes rather than go about creating the dictionary. Here's the example of extracting the rating,
NSString * xmlString = #"<channel> <item> <title> </title> <social> <views> <total_views>2</total_views> </views> <reviews> <average_rating>2</average_rating> </reviews> </social> </item> </channel>";
CXMLDocument * xmlDocument = [[[CXMLDocument alloc] initWithXMLString:xmlString options:0 error:nil] autorelease];
NSArray * nodes = [xmlDocument nodesForXPath:#"//item" error:nil];
for (CXMLElement * node in nodes) {
NSString * title = [[node nodeForXPath:#"title" error:nil] stringValue];
NSString * average_rating = [[node nodeForXPath:#"social/reviews/average_rating" error:nil] stringValue] ;
NSLog(#"%#", title);
NSLog(#"%#", average_rating);
}

try this , you need to pass readNode value like "channle", and it will return array, including child subnode
-(NSMutableArray *)parseNodeFromXML:(NSString *)strXML readForNode:(NSString *)strReadValue
{
NSError *theError = NULL;
CXMLDocument *theXMLDocument = [[CXMLDocument alloc] initWithXMLString:strXML options:0 error:&theError] ;
NSMutableArray *arrReturn = [[NSMutableArray alloc] init];
NSArray *nodes = [[theXMLDocument rootElement] nodesForXPath:strReadValue error:nil];
for (CXMLNode *itemNode in nodes)
{
NSMutableDictionary *dic = [[NSMutableDictionary alloc] init];
// PROCESS FOR READ ELEMENT ATTRIBUTES IN CURRENT NODE -------------------------
if([itemNode isMemberOfClass:[CXMLElement class]]){
CXMLElement *elements=(CXMLElement*)itemNode;
NSArray *arAttr=[elements attributes];
for (int i=0; i<[arAttr count]; i++) {
if([[arAttr objectAtIndex:i] name] && [[arAttr objectAtIndex:i] stringValue]){
[dic setValue:[[arAttr objectAtIndex:i] stringValue] forKey:[[arAttr objectAtIndex:i] name]];
}
}
}
// PROCESS FOR READ CHILD NODE IN CURRENT NODE -------------------------
for (CXMLNode *childNode in [itemNode children])
{
// NSLog(#"count -- %d --- %#",[childNode childCount],[childNode children]);
// IF ANY CHILD NODE HAVE MULTIPLE CHILDRENS THEN DO THIS....-
if ([childNode childCount] > 1)
{
NSMutableDictionary *dicChild = [[NSMutableDictionary alloc] init];
for (CXMLNode *ChildItemNode in [childNode children])
{
[dicChild setValue:[ChildItemNode stringValue] forKey:[ChildItemNode name]];
}
[dic setValue:dicChild forKey:[childNode name]];
}else
{
[dic setValue:[childNode stringValue] forKey:[childNode name]];
}
}
[arrReturn addObject:dic];
}
// NSLog(#"%#",arrReturn);
return arrReturn;
}
