Traversing XML with TBXML - Losing my mind!

[Skinzy]

I've got an xml file which i'm struggling to traverse through. I'll let you know from the off i'm new to xcode. I tried following another guide on here:

iPhone TBXML Looping And Parsing Data but for some reason it doesn't seem to work for me.

Here's my XML File:

<Locations action="Request" version="1.0">
     <location>
       <CompanyID>44502</CompanyID>
       <CompanyName>Holiday Inn</CompanyName>
       <Distance>3.58km/2.23miles</Distance>
         <tabs>
           <tab>General Information</tab>
           <tab>Add Review</tab>
         </tabs>
       <Address>
           <Address1>Holiday Inn Reading - South</Address1>
           <Address2>500 Basingstoke Road</Address2>
           <Address3/>
           <PostTown>Reading</PostTown>
           <County/>
           <PostCode>RG2 0SL</PostCode>
       </Address>
     </location>
</Locations>

I'm trying to traverse through this with TBXML to grab each of the items (I managed to do it with one, but couldn't loop through).

The .h file is:

@interface LoadXML : UIViewController {

    IBOutlet UITableView *tblLoadXML;
    NSMutableArray *records; 
    }
@property(nonatomic,retain)NSMutableArray *records;

-(void)loadRecords:(NSString *)records;
-(void)traverseElement:(TBXMLElement *)element;

@end

However I'm getting 2 errors on that saying: `Expected a type and Expected ')' before TBXMLElement.

My .M file has the following:

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *Cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (Cell == nil) {
        Cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }


    Cell.text = [records objectAtIndex:indexPath.row];

}

- (void)loadRecords:(NSString *)records {
    NSString *someXML = @"http://de0937/directenquirieswebapplicationv3.0/mobilesearch/what/0/49424/342/0/Reading/Hotels%20and%20Inns/0/0/0/0/0/search.aspx";
    TBXML *tbxml = [[TBXML tbxmlWithURL:[NSURL URLWithString:someXML]] retain];

    records = [NSMutableArray array];
    [records retain];

    if (tbxml.rootXMLElement)
        [self traverseElement:tbxml.rootXMLElement];
    [tbxml release];
}

- (void) traverseElement:(TBXMLElement *)element {
    do {
        if (element->firstChild) 
            [self traverseElement:element->firstChild];

        if ([[TBXML elementName:element] isEqualToString:@"location"]) {
            TBXMLElement *name = [TBXML childElementNamed:@"CompanyName" parentElement:element];
            TBXMLElement *distance = [TBXML childElementNamed:@"Distance" parentElement:element];

            TBXMLElement *id = [TBXML childElementNamed:@"ID" parentElement:element];

            [records addObject:[NSArray arrayWithObjects:
                                [TBXML textForElement:name],
                                [TBXML textForElement:distance],
                                [TBXML textForElement:id],nil]];  
        }
    } while ((element = element->nextSibling));  
}

I'm probably doing something very stupid, but it's driving me insane! Any help will be much appreciated.

I've put @class TBXMLElement; in my .h now which stops the error but it falls over when I load the table

If I go back to what I had before, it works but only for one item, how do I convert this to return to an array that loops through to get each one. At the moment it just lists the first one over and over again

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    
    static NSString *CellIdentifier = @"Cell";
    
    UITableViewCell *Cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (Cell == nil) {
        Cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }
      
    
    TBXML * XML = [[TBXML tbxmlWithURL:[NSURL URLWithString:@"http://www.tomstest.info/ios/results.xml"]] retain];

    TBXMLElement *rootXML = XML.rootXMLElement;
    TBXMLElement *results = [TBXML childElementNamed:@"location" parentElement:rootXML];  
    TBXMLElement *WOEID = [TBXML childElementNamed:@"CompanyName" parentElement:results]; 
    NSString *woeid = [TBXML textForElement:WOEID];

    
    Cell.text = woeid;
    return Cell;

}

Anyone?

If its multiple <Location> elements that you want to loop through you need to look for more <Location> elements like

if (loc_element !=nil) // first <Location> element
{

	// extract child element values & store

	loc_element = [TBXML nextSiblingNamed:@"Location" searchFromElement:<rootelement>];
}

hi There, I will use Skinzy code because is very very similar to my code. I'm "fighting" with XML for a days and I decided to use TBXML..

first of all I think there should be

            TBXMLElement *id = [TBXML childElementNamed:@"CompanyID" parentElement:element];

instead of

            TBXMLElement *id = [TBXML childElementNamed:@"ID" parentElement:element];

but ok.. I got very similar program and XML so I wouldn't bother you by posting it there, so where I got up today?

I successfully loaded .xml file from internet asynchronously by using GREAT tutorial from http://www.iphonedevsdk.com/forum/ip...rvice-how.html - thank you dany_dev! unfortunatelly the next part of processing xml is "so hard" for me so I get TBXML and - I got all my records in the records = [NSMutableArray array]; so up to this is all ok..


but now: I just need to do something like

textlabel1.text = load company name for company 1
textlabel2.text = load location for company 1..

and so on.. (I'm using Skinzy example to don't mess the code..)

so anyone better than me with the NSMtableArray? my array has a data but.. how to reach the data?

thank you for your answers!

EDIT: OK I GOT IT! It is necessary to have separate NSMutableArray for every "item"..


my example code:

TBXMLElement *idcko = [TBXML childElementNamed:@"id" parentElement:element];
NSString *idckoS = [TBXML textForElement:idcko];
[idckoArray addObject:idckoS];

TBXMLElement *title = [TBXML childElementNamed:@"title" parentElement:element];
NSString *titleS = [TBXML textForElement:title];
[titleArray addObject:titleS];
