<section name="JXPath 1.1 Release Notes">
<p>
Most changes in 1.1 are in the internal implementation and do not affect
public APIs. However there are some new publicly visible features:
<ul>
<li>
Full support for JDOM. Just like with DOM, if a JDOM node
is the root node of a JXPathContext, the implementation strictly follows
the XPath 1.0 standard. A JDOM node can also be a part of a mixed model,
i.e. the value of a property, variable, container, collection element
etc.
<br/>
</li>
<li>
Pointer has an additional method: getNode(), which returns the raw
value without converting it to a primitive value. This makes
a difference when you are working with DOM/JDOM and want to obtain
the Node itself, not the textual value of the Node.
<br/>
</li>
<li>
Support for DynaBeans
(see <a href="http://commons.apache.org/beanutils">Jakarta
Commons BeanUtils</a>).
<br/>
</li>
<li>
Refactored XML parsing by container to allow for alternate parsers.
All you do now is specify which model you want the container to use -
DOM (default) or JDOM. From that point the processing is transparent.
See
<a href="apidocs/org/apache/commons/jxpath/xml/DocumentContainer.html">
<code>org.apache.commons.jxpath.xml.DocumentContainer.
<br/>
</li>
<li>
The <code>format-number XSLT function is now supported.
In order to provide full conformance with the standard, we also
needed to introduce the format customization mechanism known in
XSLT as <code><xsl:decimal-format> (see
<a href="http://www.w3schools.com/xsl/el_decimal-format.asp">
W3Schools tutorial</a>). The new methods of JXPathContext:
<code>setDecimalFormatSymbols() and
<code>getDecimalFormatSymbols() fulfill that requirement.
<br/>
</li>
<li>
The <code>attribute:: axis is now supported models other than
DOM/JDOM. For beans and maps it is interpreted the same way as
the <code>"child::" axis.
<br/>
</li>
<li>
In JXPath 1.0 you could only register DynamicPropertyHandlers for
concrete classes, now you can also register them for interfaces.
<br/>
</li>
<li>
The implementation of <code>setValue() has changed for DOM/JDOM
nodes. In JXPath 1.0 it would replace text in the element, but leave
sub-elements alone. The new implementation is more consistent: it
drops all subelements first. Also, if you pass a Node as the new
value, it will insert the Node in the tree.
<br/>
</li>
<li>
If you need to evaluate multiple paths relative to a certain node
in the object graph, you can now create a relative JXPathContext.
Obtain the pointer for the location that is supposed to define
the relative context and then a relative context by calling
<code>context.getRelativeContext(pointer).
<br/>
</li>
<li>
The JUnit tests for JXPath have been completely redisigned and
significantly enhanced.
<br/>
</li>
</ul>
