In Tapestry 4:
- implement IBinding, eg. by extending AbstractBinding (you may use XPath
(see javax.xml.xpath) to select XML nodes)
- implement BindingFactory, eg. by extending AbstractBindingFactory
- register your binding using the tapestry.bindings.BindingFactories
hivemind configuration point
The build-in bindings are very good examples.
If you have a more concrete question....

Subject: How to implement custom binding expression?
Like OGNL expression, I need a new XML binding expression.
This XML expression can read property from XML document object and
update property to XML document object, no JavaBean object needed.
For example:
<input jwcid=" [EMAIL PROTECTED]" value="xml:doc.name <http://doc.name/>"/>
<input jwcid="[EMAIL PROTECTED] " value="xml:doc.age"/>
doc is a XML document object:
<person>
<name>Tim Robbin</name>
<age>28</age>
</person>
