objective c - Cocoa/Obj-C - Count elements in XML file -

An application has read some infos in a particular XML file. I'd like to add another option, here is the description:

Here is an example of my XML type file:

    
 I would like to count that   video & gt;  element  & lt; Video & gt;  is in the node. 
 For example,  2   
 How can I do this? Using NSXMLDocument?  
 I want to write results in a textfield. 
 
 Example: 
 There are  5  videos in the XML file 
 
 
 If someone can help, then it would be good! 
 Thanks in advance

 Something like this should be done. I'll leave you handling the error.  
  NSData * Data = [NSData dataWithContentsOfFile: pathToYourXMLFile]; NSError * Error = Zero; NSXML Document * Document = [[NSXML Document Alok] initWithData: Data Option: 0 Error: and Error]; If (! Error) {NSXMLElement * rootElement = [document root element]; NSUIntiger calculation = [[root element nodes forexpath: @ "// video" error: & amp; Error] count]; If (! Error) {NSString * videosCount = zero; If (calculation == 0) VideoCount = [NSString stringWithFormat: @ "There is no video in XML file."]; And if (calculation == 1) VideoCount = [NSString stringWithFormat: @ "There is 1 video in XML file."]; Other videocount = [NSString stringWithFormat: @ "There are% d video in XML file.", Counting]; [MyTextField setStringValue: VideoCount]; }} [Document release]
