Extracting the contents of elements

[Robbie Baldock <ro...@realise.com>]

This is probably a stupid question but then I am a newbie...

How do I actually extract the "value" of an element (ie: the stuff between
the tags)?

For example, I would have thought that, given a Document objDocument, to get
the value of the content_HREF element from this bit of XML:

<content_HREF>http://www.mysite.com/</content_HREF> 

I would do something like this:

NodeList objContentHREF = objDocument.getElementsByTagName("content_HREF");
String strURL = objContentHREF.item(0).getNodeValue();

But this returns null.

Extracting the contents of elementsNope!
The content of the element is contained in one or more child Text nodes.
To flatten adjacent text nodes to a single node, use normalize(), see
http://www.w3.org/TR/REC-DOM-Level-1/level-one-core.html#ID-745549614.  Note
that it works recursively; you don't have to call it a lot.  For the values
returned by getNodeValue, see the table in
http://www.w3.org/TR/REC-DOM-Level-1/level-one-core.html#ID-1950641247.
