Build Enterprise Application Integration Components using VB, SOAP and XML [Apr 30]
In today's fast paced business environment there is often a need to access various global applications, possibly maintained by different
organizations whose expertise and objectives may not be compatible with your own.
Extensible Markup Language (XML) can only partially alleviate the problem of making the disparate business applications collaborate with each other.
With the upcoming release of the Microsoft .NET framework many tools for building fast, flexible and secure intranet/internet based applications
will be available. But you can start building Enterprise Application Integration components today using VB, SOAP and XML.
In this article Dzhfafar Dzhafarov will builds a sample EAI component, which will connect an electronic procurement application to the
Enterprise Resource Planning (ERP).

Microsoft SOAP Toolkit 2.0 Gold Release now available! [Apr 25]
This is the first release of the Microsoft® SOAP Toolkit
Version 2.0. This Toolkit offers functionality similar to the MSDN SOAP Toolkit
sample, which has been available for several months, but is a fully Microsoft
supported product. This Toolkit replaces the old MSDN SOAP Toolkit.

XSLT Debugging - Under the loop [Apr 25]
This article is about the debugging of XSL Stylesheets and
how to do it with currently available XSL Debuggers. As an intro, Pieter Siegers
starts with a short explanation of what XSLT is, and how the XSLT process works.
Then we see how that process can be debugged using the Microsoft MSXML parser
and Internet Explorer 5.x, followed by a review of XSL Debuggers available at
the time of writing.

XML for Analysis Specification [Apr 23]
Check out this set of XML Message Interfaces that use the industry standard
Simple Object Access Protocol (SOAP) to define the data access interactions
between a client application and an analytical data provider (OLAP and data
mining) working over the Internet.

SAX and Microsoft XML Parser 3.0 [Apr 23]
XML is the de facto standard for working with data not only across systems, but
also for working with data locally. But the XML DOM provides its functionality
at a cost - one of which being high memory usage. The entire XML document needs
to be loaded into memory before the XML DOM is available to you. This article
discusses a COM object created by Essam Ahmed called ado2xml that allows
developers to query a database and obtain the results in XML. ado2xml is capable
of sending its output directly to a string (which you can load into an XML DOM
object using its load method), or into an ASP Response object. If you use
ado2xml on an ASP page it will, by default, send its output through the ASP
Response object directly to the client. You can disable ado2xml's use of the
ASP Response object if you want to capture its output in a string. Read on for
more detail.

SOAP Toolkit 1.0 to 2.0 Migration [Apr 21]
This sample is intended to help developers and software
architects understand the differences between the SOAP Toolkit 1.0 and 2.0
object models and infrastructure.
It demonstrates the migration
implementation using the ROPEDEMO sample application from version 1.0 of the
SOAP Toolkit.

Performance Tuning Client-Side XML in IE [Apr 17]
With XML fast becoming the lingua franca of the Internet, its use between
clients and servers continues to grow. Microsoft has fully committed to XML with
their forthcoming .NET platform, and already offer a comprehensive suite of
tools to access and manipulate XML on the client and server. However, not all
XML methods are equally efficient. Microsoft has provided many different ways of
handling XML across SQL Server, IIS and Internet Explorer. Different methods of
creating, transferring and transforming XML data are available to developers,
and in this article Mark House explores the considerations of some of the more
common ones.

MSXML 3.0 SP1 and 4.0 Technology Preview now available to download! [Apr 15]
The Microsoft® XML Parser (MSXML) 3.0 SP1 release offers a
number of key bug fixes over the MSXML 3.0 release. The MSXML 3.0 release
provides: server-safe HTTP access; complete implementation of XSL
Transformations (XSLT) and XML Path Language (XPath); changes to the Simple API
for XML (SAX2) implementation, including new SAX2 helper classes even higher
conformance with Worldwide Web Consortium (W3C) standards; the OASIS Test Suite;
and a number of bug fixes. For more information, see What's New in this release
The Microsoft® XML Parser (MSXML) 4.0 Technology Preview
offers a variety of new features, including support for the XML Schema
Definition (XSD) language, XPath extension functions for XSD, and two new
interfaces for namespace management: IMXNamespaceManager and
IMXNamespacePrefixes. The MSXML 4.0 Technology Preview also provides DOM to SAX
support, SAX to DOM support, and a new MXHTMLWriter coclass. The MSXML 4.0
Technology Preview Parser and SDK are now installed from the same Microsoft XML
Parser and SDK Setup program. The setup program installs the XML SDK in the
\program files\MSXML 4.0 folder and creates an MSXML 4.0 menu item in the
Program menu.

Modularization of XHTML™ is now a W3C Recommendation [Apr 10]
XHTML is the reformulation of HTML 4 as an application of XML. XHTML 1.0 [XHTML1] specifies three XML document types that correspond to the three HTML 4 DTDs: Strict, Transitional, and Frameset. XHTML 1.0 is the basis for a family of document types that subset and extend HTML.
XHTML Modularization is a decomposition of XHTML 1.0, and by reference HTML 4, into a collection of abstract modules that provide specific types of functionality. These abstract modules are implemented in this specification using the XML Document Type Definition language, but an implementation using XML Schemas is expected. The rules for defining the abstract modules, and for implementing them using XML DTDs, are also defined in this document.
These modules may be combined with each other and with other modules to create XHTML subset and extension document types that qualify as members of the XHTML-family of document types.
The XHTML modularization provides a means for subsetting and extending XHTML, a feature needed for extending XHTML's reach onto emerging platforms.

Using XML to Cache SQL Server Queries [Apr 09]
For websites with regular, but relatively infrequent, databases updates (for
example, a jobs portal), we can optimize our data access to avoid a performance
bottleneck by caching queries on the filesystem in XML. Instead of continually
querying against a database, users query against the XML file. In this article,
Benny Johansen and Jan Narkiewicz present a method of creating such an
automatically updating XML cache.
- XHTML™ 1.1 is now W3C Proposed Recommendation [Apr 06]
- Soap Toolkit 2.0 RC0 now available to download [Apr 03]
This is the first Release Candidate release of the Microsoft® Soap Toolkit Version 2. This Toolkit offers functionality similar to the MSDN Soap Toolkit sample which has been available for several months, but it will be a fully Microsoft-supported product. The GOLD release of this Toolkit will replace the current MSDN Soap Toolkit.
- XML Serialization [Apr 03]
In this article Matthew Reynolds looks at XML serialization. This is the
process of taking an object, turning it into an XML document and either storing
it for later use, or moving it to another part of the network for use
elsewhere. He shows us how to use the .NET XmlSerializer object to convert an
object into a block of XML and send it down one of the stream objects in the
Framework.
