Ok. Let's solve your problems :-).

Thats true a concrete instance of Document interface isn't able to apply a
XPath expression. You should do it like this:
// parse the document using SAX
Document doc = new SAXReader().read();
// create a XPath instance
XPath xpath = DocumentHelper.createXPath("foo[@name='Kevin']");
Node node = xpath.selectSingleNode(doc);
Note that you have to cast the node into a Element or a Attribute if
desired.
I will look at the cookbook if there is an error.

Look at the above shown example.

I will provide soon a chapter that should explain all you need to no to
validate a dom4j Document against XML Schema, DTD, Relax etc. Stay tuned. It will
be out tomorrow I think.

There's a exellent chapter in cookbook about this. Whats your problem with
it?
DocumentSource or DocumentResult are used according TrAX Standard.
You can also review
http://www.dom4j.org/guide.html#Styling%20a%20Document%20with%20XSLT
Maybe this helps you.

I think simple and small examples would be nice to learn how to use all the
features dom4j offers. When you by a Java Beginners book you won't find a
complex Java Application in the book. But I will offer a complex sample along
with some explainations in the next version of dom4j.
I see that you have problems understanding the modular structure of dom4j. I
will provide also a chapter that explains the this structure.
Critique about cookbook is always appricated. I just want to make things
better. But I need excat informations to do this.
Thanks
Toby
