Question

This question is for manipulating NSString in xcode.

I have a XML text string that I get from the web that looks like this

<current temperature="73" day="Mon" humidity="59" windspeed="10"></current>

How can I get individual values from this string and put them in my NSString variables?

e.g.

NSString *tempStr = ??
NSString *dayStr = ??
NSString *windspeedStr = ??

First, download and include RaptureXML within your project as described on the RaptureXML project site.

For parsing the single given line, use the following snippet – your input is passed as inXmlString;

//transform string into an XML DOM
RXMLElement *rootNode = [RXMLElement elementFromXMLString:inXmlString 
                                             withEncoding:NSUTF8StringEncoding];
if (rootNode == nil || ![rootNode isValid])
{
    //do something, we failed!
}
else 
{
    NSString *temperature = [rootNode attribute:@"temperature"];
    NSString *day = [rootNode attribute:@"day"];
    NSString *windspeed = [rootNode attribute:@"windspeed"];
}
