Reading XML data between tags

Question

I have a XML for which i am writing a servlet to pick up contents from the XML. One such tag is <itunes:author>Jonathan Kendrick</itunes:author>
I need to get author value for this. because of :

I tried using namespace and using escape sequence for : but it did not worked for me.

For rest of other XML elements i am simply using

String link=node.getChildText("link").toString();

I am using Jdom parser

in your XML the sequernce 'itunes:author' represents what's called a Q-Namem a "Qualified Name". In XML it consists of a 'Namespace prefix', and a 'Local Name'. In your example, the namespace prefix is 'itunes', and the 'local name' is 'author'.

What you want is the 'author' element in the namespace linked to the prefix 'itunes'. The actual namespace is normally a full URL. I believe the full URL for your example is probably xmlns:itunes="http://www.itunes.com/dtds/podcast-1.0.dtd", but you should check that.

So, the Namespace is "http://www.itunes.com/dtds/podcast-1.0.dtd", it's prefix is declared to be 'itunes' (but it could be something else - the actual prefix name is not technically important...)

You want to get the 'author' in the 'http://www.itunes.com/dtds/podcast-1.0.dtd' Namespace so you want:

String author = node.getChildText("author", Namespace.getNamespace("http://www.itunes.com/dtds/podcast-1.0.dtd"));
