Subject: [xsl] [ANN] DataPower Streaming XML Processing Breakthrough for XML
Documents of Unlimited Size

Hello xsl-list,

In answer to perennial questions on this list regarding the processing of
very large XML files with XSLT, I'm pleased to present the following press
release from DataPower Technology.  Check http://www.datapower.com/newsroom/

DataPower Streaming XML Processing Breakthrough Delivers Streaming XPath and
Streaming XSLT for XML Documents of Unlimited Size

In Another Industry First, DataPower Breaks the 1 Terabyte Barrier for XML
Transformation; Enabled by Six Years of XML Experience and Advanced Compiler
Research

CAMBRIDGE, Mass. - March 29, 2005 - DataPower(r), the leading provider of
application-oriented network hardware for managing, optimizing and enabling
secure XML Web services, announced today the availability of fully streaming
XML Processing in its DataPower XA35 XML Accelerator(tm)
www.datapower.com/products/xa35.html . Streaming processing allows an XML
engine to begin producing output before the entire input has been parsed and
requires only a constant amount of memory, independent of XML document size.
Previously, streaming processing was only possible using low-level custom
programming or special-purpose languages. By contrast, DataPower's
innovative approach allows XML developers to continue using familiar
XPath/XSLT standards, while seemlessly lowering latency and enabling XML
documents of unlimited size to be processed.

Some XML processing operations are not streamable by their very nature.
For example, an XSLT transformation that reverses the order of elements in a
file must necessarily buffer all of the input and wait for the last element
before it can produce any output. This has also limited the development of
general purpose streaming for XML processing, because of concerns that any
solution would be unable to support intrinsically non-streamable operations.
In a further complication, it is often difficult for a developer to
determine whether a particular set of XML processing operations can be
streamed, and to know how later changes may affect streamability.
DataPower's patented and patent-pending compiler technology automatically
determines which operations are streamable and processes them in a fully
streaming fashion. With DataPower XG4, the user is not required to learn new
languages or determine which processing is streamable, and the engine allows
for operations in XSLT and XPath, which are two of the most popular and
widespread standards for processing XML, to take place using a streaming
model.

Among many benefits of this new invention, DataPower XG4(tm) has been shown
to transform a 1 terabyte XML document in XSLT streaming mode.
Breaking the "1 Terabyte Barrier" for XML document size is another major
industry milestone. Other DataPower firsts include: breaking the "1
Gigabit/second Barrier" in 2004, receiving a patent on key XML processing
technologies in 2004, shipping the first XML Security Gateway in 2003,
announcing the first wirespeed XML Acceleration Router in 2001, creating the
first comprehensive XML benchmark (XSLTMark) in 2000, creating the first
commercial high-performance XML engine in 1999, and pioneering the XML-aware
networking sector in 1999.

"This achievement shows that despite becoming the market leader in
deployments of its mature products, DataPower continues to invest in core
technology and to remain at the forefront of R&D in XML processing," said
Bill Tao, VP engineering at DataPower, "In addition to DataPower's
unprecedented access to top tier customers, we have an amazing group of
really talented compiler, XML, hardware and security experts, and the fourth
and fifth generation technology they are developing is years ahead of the
industry."

The XA35 XML Accelerator is a member of DataPower's XML-aware networking
product family, which includes the XS40 XML Security Gateway
www.datapower.com/products/ for government-grade Web services security, the
XI50 XML Integration Appliance for SOA enablement and the XG4 XML Chipset
for OEMs..
