In the last newsletter, I discussed a really powerful and free open source tool for manipulating XML content. Today, I have a commercial product that's in more-or-less the same space.The product is Stylus Studio 2006 XML Enterprise Edition from DataDirect Technologies.DataDirect could be accused of being overachievers - Stylus Studio is a smorgasbord of tools that provides:* Numerous synchronized, visual XML editing views with the company's Sense:X, which provides intelligent XML editing, an Integrated XML Validator, and XML differencing.* XSLT debugging, XSLT mapping, XSLT profiling, visual HTML-to-XSLT stylesheet design, and XSL:FO.* Visual XQuery editing (Stylus Studio claims to be the first to market with this feature), XQuery mapping, and XQuery debugging.* Electronic Data Interchange (EDI) integration tools for converting, mapping and deploying advanced XML data integration applications for legacy EDIFACT and X12 data sources.* XML Schema editing, validation, XSD documentation generation, and other XSD utilities* A visual DTD editor, integrated DTD validator, and various DTD generation utilities.* XPath 1.0\/2.0 tools, which include XPath Evaluator, XPath Expression Generator, and the company's Sense:X for Xpath.* Web services development tools including a Web Service Call Composer, and a UDDI Registry Browser.* XML mapping tools that visually drag and drop data reformatting for XML documents, Web service data, relational data, and flat files.* Import and export utilities for any file, XML and relational data formats.* Tools to create XML views of relational databases and render relational data as XML.* A JSP Editor, XML-Java debugger, and other tools to build XML-enabled Java applications.* HTML\/XHTML and Web design tools.* Support for building XML-enabled Microsoft applications with MSXML, Microsoft .Net XML (System.XML), SQL Server 2000, and other XML-enabled products and APIs.The user interface of the Integrated Development Environment is beautiful and there are three versions: Home ($99), Professional ($450), and Enterprise ($895).This is a huge product and appears to cover perhaps the broadest selection of XML data manipulation abilities I've come across from a single vendor.
