dom4jb
is a XML-Data-Binding library for the dynamic mapping of
JavaBean
TM
-based object graphs into
a tree-based XML representation. This library makes it possible to map object
graphs at runtime into XML document models (e.g. DOM). In contrast to other
XML-Data-Binding frameworks, this mapping takes place incremental. That is,
the tree-representation becomes not necessarily fully build up, but is limited to
the most necessary.
The goal is to map large object graphs in an efficient way into a DOM or XPath-Models,
so that these can be transformed by means of XSLT.
Therefore the object graph will be maped into a XML representation at runtime, whereas
the creation of the corresponding node object of the tree representation is deferred as
long as possible. Currently two XML documents models are supported:
-
DOM
dom4jb
comes with an implementation of a readonly subset
of the
DOM-Level 2 (core)
interfaces.
This makes it possible to use
dom4jb
in conjunction with a wide variety of XSLT-processors
supporting the TrAX-API.
-
Saxon XPath
For the efficient use of
dom4jb
in conjunction with
the
Saxon XSLT-processor
, the Saxon specific
XPath
model is supported. Many XSLT processors
(i.e.
Xalan
or Saxon) are transferring the
DOM tree into an internal XPath representation before the actual transformation is done. So that
an incremental mapping would give you no performance improvement. To avoid this, the Saxon
XPath interfaces are implemented.
