We have recently blogged about the new XML Schema Designer and the various views over schemas offered by it. We visit here the concept of schema sets, which are actually the central organizing concept around what is shown in the designer for a buffer in Visual Studio for which we have XML Schema information (be it an XSD file or an XML file or Visual Basic project with associated schemas). A schema set can be thought of as a collection of pairs, the first part of each pair being an XML namespac ... [ read more ]

We have recently received a number of requests from customers who would like to use this preview in their projects and re-distribute it. We hope the CodePlex project will be able to ... [ read more ]

Complex XSLT stylesheets often contain several include and/or imports instructions. VS XML Editor has very limited support for such scenarios. (Most noticeable it lacks the concept of "primary stylesheet".)
In the XSLT Debugging session you may need to put breakpoint in the template that is defined in one of the referenced files and VS doesn't provide convenient way of opening these files.
Even more tricky is putting breakpoint on the built-in template rule . There ... [ read more ]

Converting from XmlDocument to XDocument has a number of benefits, including the ability to use LINQ to XML, use a much cleaner object model, get better name handling with XName and being able to use functional constructors. However, there are a lot of XmlDocuments out there, so what is the best way to convert a XmlDocument to an XDocument?

Over a slower link this process may take minutes and IDE will appear unresponsive.

Global Xml namespaces in VB 9.0 provide the ability to create alias for Xml namespace that can be used in the Xml axis properties and in the Xml literals. The following is an example from my previous post :
Imports ns = " http://www.w3.org/1999 "
Module Module1
Sub Main ()
Dim book = _

After my TLC session on XML Tools in Visual Studio a gentleman came up to me and asked me a question. He said that he deals with XML coming over the pipe and their usually isn’t an end-of-file character at the end of his email document. He was trying to figure out how he can create a DOM over the valid XML. He was using one reader to do this. I knew that he could use the subtree reader but I didn’t have any code handy to give him. So I played around a bit and here is what I came up with:

This post summarizes some things we've noted in tracking the reaction to XLinq in the press and blogosphere, and points to some resources we've discovered along the way.
One thing we've noted in the LINQ forum and elsewhere is that people seem to think that LINQ == DLinq, i.e. that LINQ is just some C# syntax for embedded SQL. As we see it, however, LINQ provides a model of data access that unifies query and transformation across an extensible set of domains, including ... [ read more ]

Avner has blogged about the new XML features added to VB9 in this CTP . I'll do the same for XLinq itself (and one little XML feature in the C# IDE). There have been a number of relatively small changes:
Axes that used the term "content" now use the term "nodes".
Methods have been added to make it easier to compare the document order of different nodes.
Various properties and methods have been added to make it easier to work with the information in namespace prefixes, document ty ... [ read more ]

I hope you already had the chance to download the latest LINQ CTP . This CTP contains important improvements to the Xml features in VB 9.0 which most of them are based on the feedback that we got from many people on our last CTP. This feedback is invaluable to us and to the quality of the final product, so please continue let us know what you think.
Here is a short overview of the new Xml features in VB 9.0:
Xml axis properties: The new syntax for Xml axis properties that I disc ... [ read more ]

We've been pretty quiet about the XLinq project and the XML features in Visual Basic 9 for awhile as we focused on getting out a new LINQ CTP and planning its release in the next version of Visual Studio ("Orcas"). We're very happy to report that you can now download the current state of all the LINQ technologies.
In case you haven't been following the LINQ project, it provides a common programming model for the most common types of data, including objects, relational, and XML. It i ... [ read more ]

Many people asked us why did we choose the triple dot syntax for the descendants axis in the VB 9.0 Xml members syntax. Before I go into the reasoning for that choice here is a small example of the triple dot syntax. In the following sample, the variable " authors" pointes to all the "author" elements that are descendents of the "book" element:
Dim book = < book year = " 2000 " >
&nbs ... [ read more ]

Hello All,
My name is Neetu Rajpal and I am a Program Manager in the XML Team. In this post, I want to let you know of a few additions to the XML Downloads section.
The Tools and Utilities in the XML Downloads section has always pointed to our sister GotDotNet site. In an effort to consolidate all XML related information on MSDN, we have now moved the following downloads from GotDotNet to MSDN directly. Below is a short description of what these utilities do.

Bill McCarthy asked me to post Xml axis members example using namespaces. So I updated the sample from my previous post as follows:
I added an imports statement for Xml namespace:
Imports ns = "http://someNamespace"
I also update my xml document to include namespaces:
Dim Person = _
< ns:Person ns:Dept = " SQL Server " xmlns:ns = " http://someNamespace " >

For those who do not know me yet, my name is Avner Aharoni and I am a program manager in the WebData Xml team. I am working on the VB 9.0 Xml features that I believe will make VB the most productive language with which to program Xml.
We heard from many people who tried the VB 9.0 January preview that the late-bound properties we added to XLinq objects in VB 9.0 are confusing. One reason is that it is hard to know if a certain property name refers to the u ... [ read more ]

Daniel Cazzulino has a very thought provoking post XLinq: is XML embedded in a host language a good idea or a terrible one?
I believe Microsoft should strive not to provide another technology that could potentially bring back the nightmares we lived with ASP in the past. If it can be missused, it *will* be missused .
If it were for me, I’d limit the features available on the control code snippets to just control and rendering code: if..else, for/while loops, value retrie ... [ read more ]

Thursday at PDC saw lots of details being put out about another big project our team has been working on -- the deep support for XML in Visual Basic 9. This is actually part of an even larger effort that our team member Erik Meijer has been involved in, to support fully dynamic languages such as Python in the .NET Common Language Runtime.
On the VB9 front, the big news is that two major features beyond and on top of LINQ will be supported in VB9:
"XML Literals" is t ... [ read more ]
