In my previous post I linked to a terrific website (Working with XML on Android) which describes how you can read and parse XML documents in Android. The code supplied by that website used polymorphism to show 4 different methods for parsing the XML data. I vowed to simplify that and share the new source code.
To download the AndroidXmlSimple project click here. You will be taken to another page where you can click to download to the ZIP file.
Below are some instructions on setting yourself up with this source code and customizing it for your own XML data.
1. Download the file AndroidXmlSimple.zip
2. Unzip it on your disk.
3. Open Eclipse and import the Android project into your workspace.
4. The project will look like this:
5. This new project opens up an XML document (the same RSS feed as the original example) and displays it using a ListActivity.
6. The classes are:
- MessageList.java: the main Activity
- Message.java: object that stores the parsed XML data
- RssHandler.java: object that parses the XML data
- BaseFeedParser.java: object that initiates the starting point and configurations for the XML data that should be parsed.
7. To customize this project for your own feed, edit the file BaseFeedParser.java.
Update the URL location here:
static String feedUrlString = "http://www.androidster.com/android_news.rss";
Update the hierarchy of nodes here:
static final String RSS = "rss"; static final String CHANNEL = "channel"; static final String ITEM = "item";
Update the node names that repeat here:
static final String PUB_DATE = "pubDate"; static final String DESCRIPTION = "description"; static final String LINK = "link"; static final String TITLE = "title";
And as in the previous post, if you change any names of the constants, you will need to update other sections of the code-base, for example below in BaseFeedParser.java, and in a few places in RssHandler.java.
item.getChild(TITLE).setEndTextElementListener(new EndTextElementListener(){ public void end(String body) { currentMessage.setTitle(body); } }); item.getChild(LINK).setEndTextElementListener(new EndTextElementListener(){ public void end(String body) { currentMessage.setLink(body); } }); item.getChild(DESCRIPTION).setEndTextElementListener(new EndTextElementListener(){ public void end(String body) { currentMessage.setDescription(body); } }); item.getChild(PUB_DATE).setEndTextElementListener(new EndTextElementListener(){ public void end(String body) { currentMessage.setDate(body); } });
Please leave a comment if you download this ZIP file – I’d like to know if you found this useful. And let me know if it does what you expected after reading my post. Thanks!

Very nice try and good example!
Unfortunately it works only for RSS 2.
RDF does now work, and it’s too common…

hello I read posts from kml and put them into a listview someone help me know
December 19, 2009 at 02:31
You code is superb!.
But a little bit hard for beginners.
You can write a tutorial itself with those code.
I am waiting for that. ( a little bit code explanation )
Keep the good work on.

Hey thanks for the code it helped me A LOT.
I’m making an app for Android that uses a few webservices and your simple code works. It saved me a lot of time.
Anyways, I have a question.
One of my webservices don’t work. Or better said, I can’t seem to get it to work
It’s this webservice:
http://www.pathe.nl/export/export.asmx/HaalAgenda?filmId=0&biosId=6
Can you (or someone else) tell me how I can parse this kind of webservice (cuz this is not a regular XML-service)
Thanks in advance!

Thanks for publishing that. I’d found the IBM page before and this did indeed make it that bit simpler. I haven’t been able to run the code yet as I’m at work and fighting with the Android emulator to get it through the proxy. This did however lead me to try making the XML file local (which is my final aim anyway) as res/xml/android_news.xml and tried loading it by using:
Xml.parse(appContext.getResources().openRawResource(R.xml.android_news), Xml.Encoding.UTF_8, root.getContentHandler());
The debugger tells me it’s not well formed. Googling around for solutions at the moment but it seems everyone loading local files uses getResources().getXml(blah) and uses a PullParser.
If you’ve got any advice I’d love to hear it. Thanks again.

I have a question, i working on a currency exchange.
So i need to the live data of different countries..
So how shall go about to extract out the value of it?
Email me: shiqin02@hotmail.com
February 23, 2010 at 13:41
I am in the same boat as Felicia. She needs to extract live currency info, I need to extract live stock quotes. I do it with biterscripting ( http://www.biterscripting.com ). Google up “biterscripting stock price” and it will find lots of scripts people have written. Hope this helps.

Does this also parse the “cdata” ? As a matter of fact i tried it but it is not supporting cdata tags . Can you suggest any modifications so as to parse the “cdata” tag also
thanks

Great Tutorial! Got me up and running in less then 15 minutes. Exactly what I’ve been looking for!
April 28, 2010 at 19:01
Hi!
Thanks for this code, I’ll try to adapt it to a slightly different XML structure.
Allthought that, something weird is going on when I try to run this code without modyfing it.
In a Virtual Emulator on th ePc it’s ok, but when I run it on an Android Device directly the List can’t be load.
I activated the debug mode and this is what comes up:

Thanks a lot! It really helped me.
One hint maybe:
Xml.parse(this.getInputStream(), Xml.Encoding.ISO_8859_1, root.getContentHandler());
if your are trying to parse ISO

HI,
CAn anyone help me how to extract the attribute values in the XMl file. I’m able to retrieve the normal data inside the tags but i need for the like example below:
i want to extract the value kevin and age value 20. how to modify the item code for the same????
July 15, 2010 at 19:52
Can Someone please show us how to extract attribute values?!?!?! I have been trying to learn java for android and this is the farthest i have gotten. Please someone post how to!
July 15, 2010 at 22:06
Well i downloaded your code however eclipse complains
Project has no default.properties file so i can’t use your simplified version luckily enough i’m a good enough programmer to yank out everything except the SAX code and make it work…..you should simplify all 4 parse methods as they all have a use in one use case or another.
August 6, 2010 at 04:54
Hi,
I found this article extremely helpful. Thanks for that. I had a very painful problem though.
In the message.java you are using
static SimpleDateFormat FORMATTER =
new SimpleDateFormat(”EEE, dd MMM yyyy kk:mm:ss ZZZZ”);
That could cause problems on none US devices.
This worked:
static SimpleDateFormat FORMATTER =
new SimpleDateFormat(”EEE, dd MMM yyyy kk:mm:ss ZZZZ”, Locale.US);
Regards,
Rob

Hi, I’m building a hunting application for which I need weather information in form of a RSS feed from the following site: http://www.meteo.si/uploads/probase/www/fproduct/text/sl/fcast_si-region_latest.rss
I’ve used the code from this site and it list the feeds, but when I click on an item it doesn’t connect it to the site for more information … I would like to get temperture and wind information but I don’t know how to because I’m a beginer to programing.
I would very much appreciate any help especially in form of a code that would solve my problem.
Thanks in advance

Hands down the best RSS/XML tutorial on the web, trust me, i’ve tried them all and ran into a lot of issues to the point I was just going to give up. This code is solid! I suspect you write books or something, because as a beginner, i could actually follow this

cheers mate, it’s good to have some working XML-handling code (just compiled it and it runs fine…) as a basis to work from. was really getting stressed with some other code example that i could not get to work!
@Durgesh i too had a bit of hassle. what fixed it for me was right clicking on the project, selecting “Properties” and ticking a box in Android properties that corresponded to my build platform of choice.
