Read CDATA from RSS Feed

Bernd68 · Jul 4, 2012

Hi all,

i used the example from the forum to create an RSS Reader.
It works fine for most rss-feeds, but i am struggling i.e. with the following feed, that contains a CDATA-section within "Description"

Major Economic Indicators Latest Numbers

Can anyone point me in the right direction, how to extract
the single "items/paragraphs" from the CDATA-Section?

An example would be highly appreciated.

Regards
Bernd

This XML is not built in a way that will allow you to easily find single items. All the items are encoded as HTML inside a single 'description' node. You will need to get the whole section and then manually parse it.

Unable to extract relevant text from Description element.

Hi!

I am using the RSS Reader example with the following link:

Top Headlines - The Times of India

It works perfect except for the Description element which gives the text as is.

Is there any way to extract the description text?

I am not too familiar with HTML coding, so a small example or code statement would help. Is it safe to assume that the & character is the beginning of an HTML element? Some workaround like that is also okay.

The XML parser should return the text as is. The complete text in this case is a HTML string.

You can pass it to WebView to show it.

Arun · Nov 17, 2012

Solution worked, but further help required, please

I am getting the text with webview along with the links for "Email this" and "Bookmark this" which must be a part of the Description element.

Anyway of suppressing these links, or extracting plain text from the webview and putting it in a label/button etc.

Thanks once again in advance. The quick response is highly appreciated.:icon_clap:

There is no automatic way to do it. You will need to parse the text and find the links.

Thanks!

I have done so much manually only to find a single command later on when looking up something else, which is the reason I asked.

I am a java illiterate, but am attempting to pitch an android app only because I found your product. If anything beats your product, it is your service! Combine this with your policy of posting everything on the forums, including samples/libs/code and the concepts become really clear. :sign0098:
Thanks one again for opening up a new avenue for people like me!
