     Announcing: New XML Editor in Visual Studio 2005 Beta 1

Visual Studio 2005 Beta 1
<http://lab.msdn.microsoft.com/vs2005/>contains a completely new XML
Editor, built on top of the core text editor provided by Visual Studio.
It is entirely written in C# and leverages all the cool stuff provided
by the System.Xml .NET assembly.  The new XML editor provides support
for editing XML and DTD content, including special support for XSD and
XSL.  It contains the following handy features:

     * Full syntax coloring for all XML and DTD syntax.
     * Well formedness checking while you type, with red squiggles and
       error list.
     * Intellisense based on any DTD, XDR and XSD schemas.
     * Validation-while-you-type with blue squiggles and error list.
     * Auto-completion of namespace declarations, end tags and attribute
       value quotes.
     * Support for xsi:schemaLocation and xsi:noNamespaceSchemaLocation
       attributes.
     * Schema picker dialog for overriding schemas used for validation,
       which is then remembered as a document property in your solution.
     * Schema cache for commonly used schemas with standard set provided
       out of the box.  You can easily add your own schemas here or edit
       the existing ones to constantly improve your XML editing experience.
     * Smart Formatter that is more than a pretty printer.  It honors and
       formatting of attributes that you may have done by hand and it
       fixes up the most common mistakes people make in XML, like
       unquoted attribute values.
     * Smart indenting based on XML element depth.
     * Inline expand/collapse support.
     * Easy navigation between start and end tags using brace matching
       command (Ctrl+]) .
     * Brace highlighting so you see which tags are being closed as you
       type.
     * Goto Definition command for navigating between elements and their
       associated DTD, XDR or XSD schema definitions. This command can
       also navigate from an entity reference to the entity definition in
       the DTD.
     * Tool tips that popup showing xsd:annotations for the element or
       attribute under the mouse.
     * XSL and XSD compilation errors while you type, providing even more
       error checking that can be represented in the schemas alone.
     * Show XSLT Output command available on any XML or XSLT file.


       XSD Schema Inference

The editor provides a handy command named "Create Schema" which does one
of three things:

    1. Convert associated DTD to XSD
    2. Convert associated XDR schema to XSD
    3. Infer a schema from the XML

This is by far the easiest way to get started with designing an XSD schema.


       XSLT Debugging

In non-Express SKU's only, this feature gives you a powerful XSLT
debugger, fully integrated into the overall Visual Studio debugging
experience so you can step from C# code directly into the XSLT transform
itself and back out, or from XSLT out to extension objects and back.  It
also provides a “Debug XSL” command on XML editor toolbar to start
debugging directly from XML or XSL file.

Once debugging has started the standard Visual Studio debugging menu is
available including special support for the following:

·         Setting and clearing breakpoints, at the node level (as
opposed to line level).

·         Locals window that shows XSLT variables and parameters that
are in scope.

·         Call Stack window that shows XSLT template stack.


       Deep VS Integration & Extensibility

All the advanced core text editor commands and configurability is
available, for example:

           o Fully configurable colors using standard
             Tools/Options/Environment/Fonts and Colors property page.
           o Fully integrated text editor settings (Tools/Options/Text
             Editor/XML) for general, tabs and miscellaneous settings.
           o Support for the new Visual Studio 2005 "Import/Export
             Settings" feature.

Support for multiple-views over the same buffer.  In Visual Studio 2003,
the XSD designer and grid views were only available from a tab at the
bottom of the document window, which means you could not view both ways
at the same time. This limitation has been removed, and each different
view is now a full fledged document window.

Custom XML designers can also be registered per file extension and/or
XML namespace URI, which is how the Visual Studio XSD designer, DataSet
designer, and the Grid View are associated with the XML editor.  Anyone
can now register an XML designer for a given namespace and the XML
editor will automatically provide a View Designer menu item for invoking
that designer.  In fact if you are planning a custom XML designer, I'd
love to chat about integration with this new XML text editor.

All feedback is welcome!

XML Editor team,
Microsoft.
