XML parsing on Mac. Fast and Dirty.

If you know C better than Objective-C, this is a fast and dirty way to parse an XML-file on Mac OS X:

#import <Foundation/Foundation.h>

void PrintTree(CFXMLTreeRef tree)
{
    int kids = CFTreeGetChildCount(tree);
    if (kids > 0)
    {
        int cnt = 0;
        while (cnt < kids) 
        {
            CFXMLTreeRef treeChild = CFTreeGetChildAtIndex(tree, cnt);
            
            PrintTree(treeChild);
            
            CFXMLNodeRef treeNode = CFXMLTreeGetNode(treeChild);
            //CFXMLNodeTypeCode subNodeType = CFXMLNodeGetTypeCode(treeNode);
            CFStringRef text = CFXMLNodeGetString(treeNode);
            NSLog(@"text: %@", text);
            ++cnt;
        }
    }
}

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    
    CFXMLTreeRef tree;
    NSString *str;
    NSData* data;
    
    str = [[NSMutableString alloc] initWithContentsOfFile: @"data.xml"];
    data = [str dataUsingEncoding:NSUTF8StringEncoding];
    
    tree = CFXMLTreeCreateFromData(kCFAllocatorDefault, 
                                   (CFDataRef)data, NULL, 
                                   kCFXMLParserSkipWhitespace, 
                                   kCFXMLNodeCurrentVersion);
    
    PrintTree(tree);
    
    CFRelease(tree);
    [str release];
    [pool drain];
    return 0;
}

As you see, this a Foundation Tool project. It works with data.xml located in the debug folder:

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <person>
    <name>Pavel Gnatyuk</name>
    <age>40</age>
  </person>
</root>

Of course, it could be written in the pure C. But it's enough to give a direction.
BTW, the standard way to work with the XML on iPhone is shown in this nice tutorial:
