  1. POParse XML & Retrieve Info Several layers of Nodes Deep Java/Android
    text
    copied!<p>I am working from an example provided by my professor which gets data from a weather forecast site and parses the XML file to show the weather conditions in a list. My program is similar, but I want to retrieve information that is nested within several nodes, and I don't know how to get to it. Here is the XML file I'm working from:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;DirectionsResponse&gt; &lt;status&gt;OK&lt;/status&gt; &lt;route&gt; &lt;summary&gt;S Street Viaduct&lt;/summary&gt; &lt;leg&gt; &lt;step&gt; &lt;travel_mode&gt;DRIVING&lt;/travel_mode&gt; &lt;start_location&gt; &lt;lat&gt;40.7021400&lt;/lat&gt; &lt;lng&gt;-74.0158200&lt;/lng&gt; &lt;/start_location&gt; &lt;end_location&gt; &lt;lat&gt;40.7021400&lt;/lat&gt; &lt;lng&gt;-74.0158200&lt;/lng&gt; &lt;/end_location&gt; &lt;polyline&gt; &lt;points&gt;kslwFzewbM&lt;/points&gt; &lt;levels&gt;B&lt;/levels&gt; &lt;/polyline&gt; &lt;duration&gt; &lt;value&gt;0&lt;/value&gt; &lt;text&gt;1 min&lt;/text&gt; &lt;/duration&gt; &lt;html_instructions&gt;Head &amp;lt;b&amp;gt;east&amp;lt;/b&amp;gt; on &amp;lt;b&amp;gt;S Street Viaduct&amp;lt;/b&amp;gt;&lt;/html_instructions&gt; &lt;distance&gt; &lt;value&gt;0&lt;/value&gt; &lt;text&gt;1 ft&lt;/text&gt; &lt;/distance&gt; &lt;/step&gt; &lt;duration&gt; &lt;value&gt;0&lt;/value&gt; &lt;text&gt;1 min&lt;/text&gt; &lt;/duration&gt; &lt;distance&gt; &lt;value&gt;0&lt;/value&gt; &lt;text&gt;1 ft&lt;/text&gt; &lt;/distance&gt; &lt;start_location&gt; &lt;lat&gt;40.7021400&lt;/lat&gt; &lt;lng&gt;-74.0158200&lt;/lng&gt; &lt;/start_location&gt; &lt;end_location&gt; &lt;lat&gt;40.7021400&lt;/lat&gt; &lt;lng&gt;-74.0158200&lt;/lng&gt; &lt;/end_location&gt; &lt;start_address&gt;S Street Viaduct, New York, NY 10004, USA&lt;/start_address&gt; &lt;end_address&gt;S Street Viaduct, New York, NY 10004, USA&lt;/end_address&gt; &lt;/leg&gt; &lt;copyrights&gt;Map data ©2010 Google, Sanborn&lt;/copyrights&gt; &lt;overview_polyline&gt; &lt;points&gt;kslwFzewbM&lt;/points&gt; &lt;levels&gt;B&lt;/levels&gt; &lt;/overview_polyline&gt; &lt;/route&gt; &lt;/DirectionsResponse&gt; </code></pre> <p>I'm really only interested in retrieving the info in the "html_instructions" tag, but it is nested in the "route", "leg", and "step" tags. I have seen several tutorials and questions on SO about parsing XML but couldn't seem to find a solution to this. Any direction would be greatly appreciated!</p> <p>Thanks.</p>
