    <p>I'm using BeautifulSoup 4 (bs4) to read an XML RSS feed, and have come across the following entry. I'm trying to read the content enclosed in the <code>&lt;content:encoded&gt;&lt;![CDATA[...]]&lt;/content&gt;</code> tag:</p> <pre><code>&lt;item&gt; &lt;title&gt;Foobartitle&lt;/title&gt; &lt;link&gt;http://www.acme.com/blah/blah.html&lt;/link&gt; &lt;category&gt;&lt;![CDATA[mycategory]]&gt;&lt;/category&gt; &lt;description&gt;&lt;![CDATA[The quick brown fox jumps over the lazy dog]]&gt;&lt;/description&gt; &lt;content:encoded&gt; &lt;![CDATA[&lt;p&gt;&lt;img class="feature" src="http://www.acme.com/images/image.jpg" alt="" /&gt;&lt;/p&gt;]]&gt; &lt;/content:encoded&gt; &lt;/item&gt; </code></pre> <p>As I understand it, this format is part of the <a href="https://developer.mozilla.org/en-US/docs/RSS/Article/Why_RSS_Content_Module_is_Popular_-_Including_HTML_Contents" rel="nofollow noreferrer">RSS content module</a> and is pretty common.</p> <p>I'd like to isolate the <code>&lt;content:encoded&gt;</code> tag and then read the CDATA contents. For the avoidance of doubt, the result would be <code>&lt;p&gt;&lt;img class="feature" src="http://www.acme.com/images/image.jpg" alt="" /&gt;&lt;/p&gt;</code>.</p> <p>I've looked at <a href="https://stackoverflow.com/questions/2032172/how-can-i-grab-cdata-out-of-beautifulsoup/2032252#2032252">this</a>, <a href="https://stackoverflow.com/questions/2032172/how-can-i-grab-cdata-out-of-beautifulsoup">this</a>, and <a href="https://stackoverflow.com/questions/13961831/why-is-beautifulsoup-unable-to-correctly-read-parse-this-rss-xml-document">this</a> stackoverflow post but I've not been able to figure out how to get the job done since they are not directly related to my case.</p> <p>I am using the <a href="http://www.crummy.com/software/BeautifulSoup/bs4/doc/#installing-a-parser" rel="nofollow noreferrer">lxml XML</a> parser with bs4.</p> <p>Any suggestions? thanks!</p>

    1. COThe reason for the answers your referencing won't work for you is because bs4 strips the CDATA tag away as described here http://stackoverflow.com/questions/16426507/can-cdata-sections-be-preserved-by-beautifulsoup?rq=1 and so any reference to CDATA after the soup is made is pointless. BeautifulSoup 3 does not do this and so the answer given in your reference is good for that version.

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.
