TouchXML parsing XML attributes

Question

How do I use touchXML to parse this XML? I want to store all the attributes as key/value pairs in a dictionary.

Answer 1

Use TBXML, its much easier and faster on working with XML files. Nice documentation also. Your problem with Attributes is easier solved here. http://www.tbxml.co.uk/TBXML/TBXML_Free.html

Answer 2

I found out that you have to check the child nodes are CXElements. Sometimes they're CXMLNodes and these don't have attribute properties.

Answer 3

For more information visit this post . I have given complete brief about it.

Yep ! solved your problem.

see, following code. Hope you understand. It's working for your requirement. I also have added - NSLog - Result - parsed.

-(void)methodForParsingPlayers{
    NSMutableArray *ar=[[NSMutableArray alloc] init];
    CXMLDocument *doc=[[[CXMLDocument alloc] initWithData:[NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Players" ofType:@"xml"]] options:0 error:nil] autorelease];

    NSArray *nodes=nil;
    nodes=[doc nodesForXPath:@"//Player" error:nil];

    NSString *strValue;
    NSString *strName;

    for (CXMLElement *node in nodes) {
        NSMutableDictionary *object=[[NSMutableDictionary alloc] init];

        // process to set attributes of object ----------------------------------------
        NSMutableDictionary *objectAttributes=[[NSMutableDictionary alloc] init];
        NSArray *arAttr=[node attributes];
        NSUInteger i, countAttr = [arAttr count];
        for (i = 0; i < countAttr; i++) {
            strValue=[[arAttr objectAtIndex:i] stringValue];
            strName=[[arAttr objectAtIndex:i] name];
            if(strValue && strName){
                [objectAttributes setValue:strValue forKey:strName];
            }
        }
        [object setValue:objectAttributes forKey:[node name]];
        [objectAttributes release]; objectAttributes=nil;
        // --------------------------------------------------------------------------------

        // process to read elements of object ----------------------------------------
        NSUInteger j, countElements = [node childCount];
        CXMLNode *element;
        NSMutableDictionary *elementDictionary=nil;
        for (j=0; j<countElements; j++) {
            element=[node childAtIndex:j];
            elementDictionary=[[NSMutableDictionary alloc] init];

            // process to read element attributes ----------------------------------
            if([element isMemberOfClass:[CXMLElement class]]){
                CXMLElement *element2=(CXMLElement*)element;
                arAttr=[element2 attributes];
                countAttr=[arAttr count];
                for (i=0; i<countAttr; i++) {
                    strName=[[arAttr objectAtIndex:i] name];
                    strValue=[[arAttr objectAtIndex:i] stringValue];
                    if(strName && strValue){
                        [elementDictionary setValue:strValue forKey:strName];
                    }

            }
            // ---------------------------------------------------------------------

            // check if object/dictionary exists for this key "name"
            strName=[element name];
            if([object valueForKey:strName]){
                if([[object valueForKey:strName] isKindOfClass:[NSMutableDictionary class]]){
                    NSMutableDictionary *d=[[NSMutableDictionary alloc] initWithDictionary:[object valueForKey:strName]];
                    NSMutableArray *arOFSameElementName=[[NSMutableArray alloc] initWithObjects:d,elementDictionary,nil];
                    [object setValue:arOFSameElementName forKey:strName];
                    [d release]; d=nil;
                    [arOFSameElementName release]; arOFSameElementName=nil;

    NSLog(@"%@",[ar description]);
