iPhone : xml parsing problem

Question

hi all,

I do have an xml file like,

<posts>
    <   photo id="12412" private="false"   >

      <title>happy_diwali_diya_wallpaper</title>
    <caption>Happy Diwali</caption>
    <dateCreated>2010-10-14</dateCreated>
    <dateLastUpdated>2010-10-14</dateLastUpdated>
    <postDate>2010-10-14</postDate>
    <orientation>HORIZONTAL</orientation>
    <sortOrder>0</sortOrder>
    <gallery id="4602">my gallery</gallery>
    <photoData>
        <image size="medium">/photos/medium/12412.PNG</image>
        <image size="original">/photos/original/12412.jpg</image>
        <image size="thumbnail">/photos/thumbnail/12412.PNG</image>
        <image size="smallThumbnail">/photos/smallThumbnail/12412.PNG</image>
    </photoData>
</photo>
</posts>

Edit: Here are some code,

// Initialize the blogEntries MutableArray that we declared in the header
blogEntries = [[NSMutableArray alloc] init];    

// Convert the supplied URL string into a usable URL object
//    NSURL *url = [NSURL URLWithString: blogAddress];

NSURL *url = [[NSURL alloc] initFileURLWithPath:blogAddress];

// Create a new rssParser object based on the TouchXML "CXMLDocument" class, this is the
// object that actually grabs and processes the RSS data
CXMLDocument *rssParser = [[[CXMLDocument alloc] initWithContentsOfURL:url options:0 error:nil] autorelease];

// Create a new Array object to be used with the looping of the results from the rssParser
NSArray *resultNodes = NULL;

// Set the resultNodes Array to contain an object for every instance of an  node in our RSS feed
resultNodes = [rssParser nodesForXPath:@"//photo" error:nil];

// Loop through the resultNodes to access each items actual data
for (CXMLElement *resultElement in resultNodes) {

    // Create a temporary MutableDictionary to store the items fields in, which will eventually end up in blogEntries
    NSMutableDictionary *blogItem = [[NSMutableDictionary alloc] init];

    // Create a counter variable as type "int"
    int counter;
    NSLog(@"%d",[resultElement childCount]);
    // Loop through the children of the current  node
    for(counter = 0; counter < [resultElement childCount]; counter++) {


//Here I am getting Crashed


        if ([[[resultElement childAtIndex:counter] name] isEqualToString:@"photoData"]) {
            NSLog(@"%@",[resultElement children]);
        }
        else {
        // Add each field to the blogItem Dictionary with the node name as key and node value as the value
        [blogItem setObject:[[resultElement childAtIndex:counter] stringValue] forKey:[[resultElement childAtIndex:counter] name]];
        }   
    }

    // Add the blogItem to the global blogEntries Array so that the view can access it.
    [blogEntries addObject:[blogItem copy]];
}

in that

till the gallary tag I am able to parse the file , but I am not able to parse the < PhotoData> tag.

Can any one help me how to parse that tag, so that I can get the details of < image> tag in the same.

thanks in advance.
