    <p>I am working on an iPhone project that needs to parse some xml. The xml may or may not include a default namespace. I need to know how to parse the xml in case it uses a default namespace. As I need to both read an write xml, I'm leaning towards using KissXML, but I'm open for suggestions.</p> <p>This is my code:</p> <pre><code>NSString *content = [NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"bookstore" ofType:@"xml"] encoding:NSUTF8StringEncoding error:nil]; DDXMLDocument *theDocument = [[DDXMLDocument alloc] initWithXMLString:content options:0 error:nil]; NSArray *results = [theDocument nodesForXPath:@"//book" error:nil]; NSLog(@"%d", [results count]); </code></pre> <p>It works as expected on this xml:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;bookstore&gt; &lt;book category="COOKING"&gt; &lt;title lang="en"&gt;Everyday Italian&lt;/title&gt; &lt;/book&gt; &lt;book category="CHILDREN"&gt; &lt;title lang="en"&gt;Harry Potter&lt;/title&gt; &lt;/book&gt; &lt;/bookstore&gt; </code></pre> <p>But when the xml has a namespace, like this, it stops working:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;bookstore xmlns="[INSERT RANDOM NAMESPACE]"&gt; &lt;book category="COOKING"&gt; &lt;title lang="en"&gt;Everyday Italian&lt;/title&gt; &lt;/book&gt; &lt;book category="CHILDREN"&gt; &lt;title lang="en"&gt;Harry Potter&lt;/title&gt; &lt;/book&gt; &lt;/bookstore&gt; </code></pre> <p>Of course, I could just preprocess the string and remove the xmlns, though that feels like a sort of ugly hack. What is the proper way to handle this?</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.
