XsltTransformer interface has two new methods,
These define the
URIResolver used for resolving calls to
DocumentBuilder class has a new method
This gives access to a class that allows a Saxon document tree
to be built programmatically by writing Stax
XMLStreamWriter events. This is a lot easier than the previous alternatives, of generating SAX events
Receiver events. This mechanism is supported by an underlying class
which converts Stax
Receiver events. Note: this class does not cache the
NamePool: it may therefore generate a high level of contention if used in a multithreading
DocumentBuilder class has a new method
This returns a SAX
which events may be sent to build a tree programmatically. Although slightly less convenient than the
XMLStreamWriter interface, this
is useful for the many cases where an existing application already generates SAX events.
The specification of the
class has been clarified to state that the event stream written
XdmDestination must constitute either a single tree that is rooted at a document or element node,
or an empty sequence; and the implementation has been changed to enforce this. This means
that when this class is used for the destination of an XQuery query, an exception is thrown if the query returns
atomic values, nodes other than document or element nodes, or sequences of multiple nodes. Previously
the effect in such cases was poorly specified and could lead to internal exceptions with poor diagnostics.
XdmNode class now has a public constructor allowing a
NodeInfo to be wrapped.
Processor class now has a public constructor allowing a
Configuration to be wrapped.
Processor class now has a number of convenience
factory methods allowing a
Serializer to be constructed.
There is also a method
setProcessor() that allows the
Serializer to retain a connection with a
Processor, and hence a
configuration. This enables new methods on the
Serializer to be simplified, avoiding the need to supply a
(or Configuration) on the method call. Eventually the free-standing constructors on
Serializer may be deprecated.
Serializer class has two new convenience methods,
allowing serialization of an
XdmNode to an arbitrary
or more simply to a Java string.
Serializer class has a new method
to be constructed as a front-end to this
Serializer. This is a very convenient way of generating serialized XML output from a Java
application: for an example of its use, see the XSLT test suite driver in the samples directory.
XPathCompiler object now has the ability to maintain a cache of
compiled XPath expressions. If this feature is enabled, any attempt to compile
an expression first causes a lookup in the cache to see whether the same expression has already been compiled. The cache is cleared
if any changes to the static context are made (for example, changing the namespace declarations in force).
XPathCompiler object has two new convenience methods,
an expression to be compiled and executed with a single call. This works especially well when the compiler is also caching compiled expressions.
Running a pipeline of XSLT transformations by using each
Destination of the previous one is now more efficient;
the code has been changed so that the second transformation does not start until the stack and heap for the first one have been released.
This has entailed a minor change to the
Destination interface: it now has a
close() method; and it also means
XsltTransformer is not serially reusable. You should create a new
XsltTransformer for each transformation
(while reusing the
XsltExecutable, of course).
XQueryEvaluator has a new method
that allows any user-declared function within the
compiled query to be called directly from the Java application. This in effect enables the creation of a query library containing
multiple functions that can be invoked from the calling application. Note that to compile a query, it must still have a "main query"
to satisfy the syntax rules of the XQuery language.
