Add support for CDATA

This is still the same issue as in #280 but since it is closed I reopen it.

Problem

I need the following XML output:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
  <channel>
    <title>My Feed</title>
    <link>http://foo</link>
    <description>My description</description>
    <item>
      <title>item title</title>
      <link>http://bar</link>
      <description><![CDATA[ <hello>world</hello> ]]></description>
    </item>
  </channel>
</rss>

However, I only get ROME to output this:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
  <channel>
    <title>My Feed</title>
    <link>http://foo</link>
    <description>My description</description>
    <item>
      <title>item title</title>
      <link>http://bar</link>
      <description>&lt;![CDATA[ &lt;hello&gt;world&lt;/hello&gt; ]]&gt;</description>
    </item>
  </channel>
</rss>

Apparently the CDATA section is ignored and the content of “description” is escaped.

Question Is there any constellation how I can get ROME to produce an RSS V2 feed with an unescaped “description” section? Unfortunately I am implementing a given requirement so it has to be the “description” field.

This is my current code:

Channel feed = new Channel();
feed.setFeedType("rss_2.0");
feed.setTitle("My Feed");
feed.setDescription("My description");
feed.setLink("http://foo");
feed.setUri("http://feed-address");

Item item = new Item();
item.setTitle("item title");
item.setLink("http://bar");
Description description = new Description();
description.setType("application/xml");
description.setValue("<![CDATA[ <hello>world</hello> ]]>");
item.setDescription(description);

feed.setItems(Arrays.asList(item));

System.out.println(new WireFeedOutput().outputString(feed));

Many thanks for your support.

Hi @samba2,

ROME does currently not support unescaped CDATA sections. The reasons are already explained the given issue #280. We currently have no resources to implement this feature.

If you don’t need other functionalities of ROME other than generating an RSS 2.0 feed, you have the possibility to use any XML library for that purpose at the moment.

I hope this helps. I’ll leave this issue open, maybe we will find some time to add CDATA support.

Regards, Patrick

@SvenWoltmann I came here due to smart news, too; here’s my dirty solution:

import org.jdom2.CDATA;

// ...

public void generateAnalytics(final SmartNewsFeedEntryModuleImpl snf, final Element element) {
        if (snf.getGaProperty() != null
                && snf.getGaCookieDomain() != null
                && snf.getPageUrl() != null
        ) {
            String gaScript = "<script>"
                    + "(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){"
                    + "(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),"
                    + "m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)"
                    + "})(window,document,'script','//www.google-analytics.com/analytics.js','ga');"
                    + "ga('create', '%s', '%s');"
                    + "ga('require', 'displayfeatures');"
                    + "ga('set', 'referrer', 'http://www.smartnews.com/');"
                    + "ga('send', 'pageview', '%s');"
                    + "</script>";

            gaScript = String.format(
                    gaScript,
                    snf.getGaProperty(),
                    snf.getGaCookieDomain(),
                    snf.getPageUrl()
            );

            Element snfEl = new Element("analytics", NAMESPACE);
            snfEl.addContent(new CDATA(gaScript));

            element.addContent(snfEl);
        }
    }
