    <p>this is a follow up to a question I posted yesterday.</p> <p>Given the cars XML example posted below, I run do an xpath query, loop through the results and call "quickquery - getString" with the sub element. I would expect that with each iteration of the loop I would get a single element inside the getString function, but I don't. Instead, the nodesForXPath call, inside of the getString function, returns all 4 car names, instead of just the one that belongs to that sub element.</p> <pre><code>NSArray *listings = [response nodesForXPath:@"//car" error:&amp;error]; //4 car elements found if(listings.count &gt; 0) { for (GDataXMLElement *listingElement in listings) { //printing listingElements description at this point reveales only one car [QuickQuery getString:listingElement fromXPath:@"//name"]; } } //this is defined in QuickQuery class +(NSString *) getString:(GDataXMLElement *)element fromXPath:(NSString *)xPath { NSError *error; //Query the name element for the spcific car element passed in NSArray *result = [element nodesForXPath:xPath error:&amp;error]; /// ***THIS CALL //result.count is 4 at this stage ("BMW", "VW" ... etc) //out of the 4 calls made to this method, I would expect each value to come up once //but each time all 4 values are found. if(result.count &gt; 0) { GDataXMLElement *singleValue = (GDataXMLElement *) [result objectAtIndex:0]; return singleValue.stringValue; } return nil; } &lt;cars&gt; &lt;car&gt; &lt;name&gt;VW&lt;/name&gt; &lt;/car&gt; &lt;car&gt; &lt;name&gt;BMW&lt;/name&gt; &lt;/car&gt; &lt;car&gt; &lt;name&gt;Mazda&lt;/name&gt; &lt;/car&gt; &lt;car&gt; &lt;name&gt;Nissan&lt;/name&gt; &lt;/car&gt; &lt;/cars&gt; </code></pre> <p>This question has been posted before, this is just a cleaner example and code. The title is also more specific.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
