Fails parsing cdata markup that is followed by escaped markup

[dy-dx]

When parsing this valid xml:

<rss version="2.0">
  <channel>
    <item>
      <description>
        <![CDATA[<a src="http://foo.com?foo&bar=baz"></a>]]>&amp;
      </description>
    </item>
  </channel>
</rss>

gofeed fails with the error message:

unknown predefined entity &bar=baz"></a>]]>&amp;

I can confirm that this is not a problem of encoding/xml which has no problems decoding this input. See https://play.golang.org/p/wWJicjEa-iv

@dy-dx @lutzhorn thank you for the report and confirmation.

CDATA parsing is currently a hack and needs to be rewritten. We aren't using encoding/xml's Unmarshal because it wasn't flexible enough for gofeed's requirements, so we don't get it for free.

I'll try to take a look at CDATA handling soon. Perhaps we can pull some code from encoding/xml itself.
