Question

any body know how to parse a dynamic xml. I have an XML with some tags. here is a tag videos like:

<Videos>
   <video>"Video link"</Video>
</Videos>

now in this XML, tags in <Videos> can be changed they could be <video> or <image> or <clip> or any thing else. So is it possible to parse that XML? how can i detect that tag what is the name of tag or what is in this tag?

I use touch xml to solve this issue

I am using in

NSError * theError=nil;

    NSMutableArray *res = [[NSMutableArray alloc] init];


NSString *XMLPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"sample.xml"];

NSData *XMLData   = [NSData dataWithContentsOfFile:XMLPath];

CXMLDocument *doc = [[[CXMLDocument alloc] initWithData:XMLData options:0 error:nil] autorelease];



NSArray *nodes = NULL;



nodes = [doc nodesForXPath:@"//sample" error:nil];



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

        NSString * a=[NSString stringWithFormat:@"%@%d",[[node childAtIndex:counter] name],counter+1];

        [item setObject:[[node childAtIndex:counter] stringValue] forKey:a];

    }


    //NSLog(@"%)
    //  and here it is - attributeForName! Simple as that.

    [item setObject:[[node attributeForName:@"id"] stringValue] forKey:@"id"];  // <------ this magical arrow is pointing to the area of interest



    [res addObject:item];

    [item release];

}



//  and we print our results

NSLog(@"%@", res);

[res release];
