Create Standards-conformant XML Documents
XMLSpy
  abstracts away the complexity of working with XML-based technologies 
through its intuitive user interface and rich variety of 
					XML editing
				 views and options. Five synchronized XML editing views allow 
you to work with any XML technology in a way that best suits the 
complexity of the document and your preferences, for instance, if you 
prefer to develop in a text view, graphical view, or switch back and 
forth between the two. 
			 XMLSpy versions 2010r2 and later  contain a number of optimizations 
for loading very large files – 10 MB and greater – in Text View in both 
the 32 and 64-bit versions. For instance, a sample 100 MB file should 
open about 15 times faster compared to previous product versions. XML 
Schema-based validation is also optimized in Text View, where you should
 receive validation results against large files up to three times 
faster.  In Grid View, you can now perform certain common operations 
(e.g., copy/paste) on large files 10-100 times faster!* 
XMLSpy
 is available in a native 64-bit version, allowing it to take full 
advantage of optimizations associated with 64-bit operating systems. 
This  also solves problems associated with processing very large, 
gigabyte-sized XML files - the only limitation now is imposed by the 
available memory on the user’s machine.**
XMLSpy XML Editor
XMLSpy provides unsurpassed compliance with the latest industry standards, including XML, DTD, XML Schema, XSLT 1.0 and 2.0, XPath 1.0 and 2.0, XQuery, and XML Signature,  as well as SOAP and WSDL 1.1 / 2.0 for Web services development. Support is also provided for the Office Open XML
 (OOXML) formats standardized by ISO and utilized by Microsoft Office 
2007 (and higher), allowing you to extract, edit, query, and transform 
the vast amount of data stored Microsoft Word, Excel, and PowerPoint 
documents.  XMLSpy even supports XBRL, the open standard for business 
and financial reporting, with full  XBRL and Dimensions validation and a graphical XBRL taxonomy editor. 
The intelligent editing features of XMLSpy support strong XML validation, auto completion, context sensitive syntax help, entry helpers, syntax coloring, wizards, debuggers, profilers, and more to aid you in creating well-formed, valid XML documents with ease.
The views, wizards, and intelligent XML editing functions in XMLSpy  are
 designed to make working with documents as easy as possible. When 
working with XML is easy, productivity increases, saving money and 
decreasing time-to-market for your applications. 
Develop Advanced XML Applications
Adding
 to its powerful XML modeling, editing, validation, and debugging 
capabilities,  XMLSpy supports the complementary technologies required 
to build the most advanced XML-based applications. Because XML documents
 must be bound to an external software application or runtime 
environment, the XMLSpy includes automatic code generation of Java, C++, or C# class files based on data elements defined in a schema. 
In addition, most advanced applications require interaction with relational databases,
 which house the majority of business information today. XMLSpy supports
 the most popular relational databases in their native interface 
languages, allowing you to query, view, and edit database data; generate
 XML Schemas based on database structures; import and export database 
data;  generate relational database schemas from XML Schemas; and much 
more. 
XMLSpy is the only tool on the market that lets you tackle Web services development
 on all of the major Web services platforms, including Microsoft .NET, 
J2EE, and Eclipse. Support for both WSDL 1.1 and 2.0 in the graphical WSDL editor
 allows you to work with the WSDL version  your company has standardized
 on and even convert between WSDL 1.1 and WSDL 2.0 with a single click. 
XMLSpy even includes a JSON editor and JSON / XML converter to facilitate the development of Web services and Web 2.0 apps.
Support for integration with Microsoft® Visual Studio® and Eclipse
 allows you to seamlessly access the powerful features of the XML editor
 from within your choice of multi-purpose development environment. You 
can also access many of the powerful XMLSpy functions in a programmatic 
way using the Java or COM systems integration API.
 And, if you want to embed the some or all of its features and 
functionality in your own applications, XMLSpy supports OLE and ActiveX 
control. 
Adding to all this advanced 
functionality, XMLSpy® 2013 is the only XML editor to support the 
creation of pie, bar, line, and gauge charts to display, analyze, and report XML data.
