Gram one piece of data from XML

[joeallenpro]

Hi guys

I need a quick lesson on grabbing data from XML...

I need to get the XML from a URL e.g: http://www.website.com/pathtoxml/?city=xxxxxxxx

here's an example of the XML:

<current_conditions>
<condition data="Clear"/>
<temp_f data="54"/>
<temp_c data="12"/>
<humidity data="Humidity: 77%"/>
<icon data="sunny.gif"/>
<wind_condition data="Wind: S at 6 mph"/>
</current_conditions>
<forecast_conditions>
<day_of_week data="Thu"/>
<low data="43"/>
<high data="70"/>
<icon data="sunny.gif"/>
<condition data="Clear"/>
</forecast_conditions>
<forecast_conditions>
<day_of_week data="Fri"/>
<low data="46"/>
<high data="63"/>
<icon data="chance_of_rain.gif"/>
<condition data="Chance of Rain"/>
</forecast_conditions>

Whats the easiest way to grab the "temp_c" from inside <current_conditions>


Thanks guys!

Some code I had to hand

@implementation DoSomething

-(void)ReadXMLAsString:(NSString*)xmlAsString
{
	
	
	NSData *data = [xmlAsString dataUsingEncoding:NSUTF8StringEncoding];
	NSXMLParser *parser = [[NSXMLParser alloc] initWithData:data];
	[parser setDelegate:self];
	[parser parse];
	NSError *err = [parser parserError];
    
    if (err != nil)
    {
       NSLog([err localizedDescription]);

    }
    
    [parser release];

}

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
	if (qName)
	{
		elementName = qName;
	}
	
	if ([elementName isEqualToString:@"temp_c"])
	{
		m_someData = [[attributeDict valueForKey:@"data"] intValue];
	}
}

- (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{    
}
- (void)parser:(NSXMLParser *)parser foundCDATA:(NSData *)CDATABlock
{
    m_contents = [[NSString alloc] initWithData:CDATABlock encoding:NSUTF8StringEncoding];
}

@end
