    <p>I am parsing a rss feed xml on android and was able to retrieve all other content but failed to retrieve the images in the feeds.</p> <p>i am using sax parser.</p> <p>The images are embedded in <code>&lt;media:thumbnail&gt;</code> tag. It looks like this. </p> <pre><code>&lt;media:thumbnail&gt;http://www.*some_website*.com/..../Client000040008200000082068.jpg&lt;/media:thumbnail&gt; </code></pre> <p>i have seen many examples but they parse from the links embedded url, also seen links embedded like this </p> <pre><code> &lt;media:thumbnail="link here"&gt;&lt;/media:thumbnail&gt; </code></pre> <p>are they both same? and how to parse such tags?</p> <p>Please help me with answers.</p> <p>Thank you.</p> <p><strong>EDIT</strong></p> <p>this is my rss handler</p> <pre><code>public void startDocument() throws SAXException { mFeed = new Feed();

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.
