    <p>I am trying to parse xml using the touchXML library but not getting the results, the code is as below </p> <pre><code>NSError *error = nil; CXMLDocument *xmlParser = [[CXMLDocument alloc] initWithXMLString:dataString options:0 error:&amp;error]; NSArray *resultNodes = NULL; resultNodes = [xmlParser nodesForXPath:@"//entry" error:&amp;error]; for (CXMLElement *resultElement in resultNodes) { NSMutableDictionary *blogItem = [[NSMutableDictionary alloc] init]; int counter; for(counter = 0; counter &lt; [resultElement childCount]; counter++) { [blogItem setObject:[[resultElement childAtIndex:counter] stringValue] forKey:[[resultElement childAtIndex:counter] name]]; } } </code></pre> <p>the method nodesForXPath: doesn't returns anything leaving the resultNodes array with 0 objects. I am getting the proper xml in dataString and the CXMLDocument is also getting prepared properly. I tried debugging it but there is nothing I can see accept the 0 objects in resultNodes, NSError also contains nothing (i.e. no error occurs). the xml file I am trying to parse is as below.</p> <pre><code>&lt;feed xmlns:s="http://syndication.nhschoices.nhs.uk/services" xmlns="http://www.w3.org/2005/Atom"&gt; &lt;title type="text"&gt;...&lt;/title&gt; &lt;id&gt;...&lt;/id&gt; &lt;rights type="text"&gt;© Crown Copyright 2009&lt;/rights&gt; &lt;updated&gt;2012-04-27T11:33:02+01:00&lt;/updated&gt; &lt;category term="Search"/&gt; &lt;logo&gt;...&lt;/logo&gt; &lt;author&gt;...&lt;/author&gt; &lt;s:SearchCoords&gt;174900,517900&lt;/s:SearchCoords&gt; &lt;entry&gt; &lt;id&gt; http://v1.syndication.nhschoices.nhs.uk/organisations/gppractices/32248 &lt;/id&gt; &lt;title type="text"&gt;Sayer A&lt;/title&gt; &lt;updated&gt;2012-04-27T10:33:02Z&lt;/updated&gt; &lt;link rel="self" title="Sayer A" href="http://v1.syndication.nhschoices.nhs.uk/organisations/gppractices/32248?apikey=YAHUGHET"/&gt; &lt;link rel="alternate" title="Sayer A" href="http://www.nhs.uk/ServiceDirectories/Pages/GP.aspx?pid=15F37AEF-EC5B-4A90-9E72-269ADEB39629"/&gt; &lt;content type="application/xml"&gt; &lt;s:organisationSummary&gt; &lt;s:name&gt;Sayer A&lt;/s:name&gt; &lt;s:address&gt; &lt;s:addressLine&gt;The Richmond Green Medical Cen&lt;/s:addressLine&gt; &lt;s:addressLine&gt;19 The Green&lt;/s:addressLine&gt; &lt;s:addressLine&gt;Richmond&lt;/s:addressLine&gt; &lt;s:addressLine&gt;Surrey&lt;/s:addressLine&gt; &lt;s:postcode&gt;TW91PX&lt;/s:postcode&gt; &lt;/s:address&gt; &lt;s:contact type="General"&gt; &lt;s:telephone&gt;020 83327515&lt;/s:telephone&gt; &lt;/s:contact&gt; &lt;s:geographicCoordinates&gt; &lt;s:northing&gt;174900&lt;/s:northing&gt; &lt;s:easting&gt;517800&lt;/s:easting&gt; &lt;s:longitude&gt;-0.305512266736965&lt;/s:longitude&gt; &lt;s:latitude&gt;51.4608026642546&lt;/s:latitude&gt; &lt;/s:geographicCoordinates&gt; &lt;s:Distance&gt;0.1&lt;/s:Distance&gt; &lt;/s:organisationSummary&gt; &lt;/content&gt; &lt;/entry&gt; &lt;entry&gt; &lt;id&gt; http://v1.syndication.nhschoices.nhs.uk/organisations/gppractices/33420 &lt;/id&gt; &lt;title type="text"&gt;Griffiths W&lt;/title&gt; &lt;updated&gt;2012-04-27T10:33:02Z&lt;/updated&gt; &lt;link rel="self" title="Griffiths W" href="http://v1.syndication.nhschoices.nhs.uk/organisations/gppractices/33420?apikey=YAHUGHET"/&gt; &lt;link rel="alternate" title="Griffiths W" href="http://www.nhs.uk/ServiceDirectories/Pages/GP.aspx?pid=EEC98A8A-B888-4F44-A0B6-DC6ABCBF19CE"/&gt; &lt;content type="application/xml"&gt; &lt;s:organisationSummary&gt; &lt;s:name&gt;Griffiths W&lt;/s:name&gt; &lt;s:address&gt; &lt;s:addressLine&gt;Paradise Road Surgery&lt;/s:addressLine&gt; &lt;s:addressLine&gt;37 Paradise Road&lt;/s:addressLine&gt; &lt;s:addressLine&gt;Richmond&lt;/s:addressLine&gt; &lt;s:addressLine&gt;Surrey&lt;/s:addressLine&gt; &lt;s:postcode&gt;TW91SA&lt;/s:postcode&gt; &lt;/s:address&gt; &lt;s:contact type="General"&gt; &lt;s:telephone&gt;020 89402423&lt;/s:telephone&gt; &lt;/s:contact&gt; &lt;s:geographicCoordinates&gt; &lt;s:northing&gt;174800&lt;/s:northing&gt; &lt;s:easting&gt;518100&lt;/s:easting&gt; &lt;s:longitude&gt;-0.301388352909701&lt;/s:longitude&gt; &lt;s:latitude&gt;51.4601120315006&lt;/s:latitude&gt; &lt;/s:geographicCoordinates&gt; &lt;s:Distance&gt;0.223606797749979&lt;/s:Distance&gt; &lt;/s:organisationSummary&gt; &lt;/content&gt; &lt;/entry&gt; &lt;entry&gt; &lt;id&gt; http://v1.syndication.nhschoices.nhs.uk/organisations/gppractices/33035 &lt;/id&gt; &lt;title type="text"&gt;Dr Da Costa&lt;/title&gt; &lt;updated&gt;2012-04-27T10:33:02Z&lt;/updated&gt; &lt;link rel="self" title="Dr Da Costa" href="http://v1.syndication.nhschoices.nhs.uk/organisations/gppractices/33035?apikey=YAHUGHET"/&gt; &lt;link rel="alternate" title="Dr Da Costa" href="http://www.nhs.uk/ServiceDirectories/Pages/GP.aspx?pid=EDCE215D-6412-4AAB-AFC4-9F37888D413C"/&gt; &lt;content type="application/xml"&gt; &lt;s:organisationSummary&gt; &lt;s:name&gt;Dr Da Costa&lt;/s:name&gt; &lt;s:address&gt; &lt;s:addressLine&gt;The Vineyard Surgery&lt;/s:addressLine&gt; &lt;s:addressLine&gt;35 The Vineyard&lt;/s:addressLine&gt; &lt;s:addressLine&gt;Richmond&lt;/s:addressLine&gt; &lt;s:addressLine&gt;Surrey&lt;/s:addressLine&gt; &lt;s:postcode&gt;TW106PP&lt;/s:postcode&gt; &lt;/s:address&gt; &lt;s:contact type="General"&gt; &lt;s:telephone&gt;020 89480404&lt;/s:telephone&gt; &lt;/s:contact&gt; &lt;s:geographicCoordinates&gt; &lt;s:northing&gt;174600&lt;/s:northing&gt; &lt;s:easting&gt;518100&lt;/s:easting&gt; &lt;s:longitude&gt;-0.301044685875553&lt;/s:longitude&gt; &lt;s:latitude&gt;51.4581333717098&lt;/s:latitude&gt; &lt;/s:geographicCoordinates&gt; &lt;s:Distance&gt;0.360555127546399&lt;/s:Distance&gt; &lt;/s:organisationSummary&gt; &lt;/content&gt; &lt;/entry&gt; </code></pre>

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.
