Restructure XML with Transformation file in ASP.NET
Shows how to restructure XML with Transformation files in ASP.NET
XML files can be structured differently. Some express
properties of elements as attributes, whereas others express them as
elements with inner text.
When working with the forementioned type
of XML file (properties expressed as attributes), we are unable to
access and display these attributes with such controls as the GridView.
However, Visual Studio will enable us to transform the file so we can
use it better.
This tutorial will show how we can create a
Transformation file and use it to transform the XML file, so we can use
all elements as originally intended.
We moved our web sites to Server Intellect and have found them to be incredibly professional. Their setup is very easy and we were up and running in no time.
An example XML file with properties expressed as attributes:
Pirates of Penzance
12.95
<:userComment rating="4">Best translation I've seen.
I like other versions better.
Being John Malkovich
24.95
Very good.
Excellent.
The Mist
24.95
Pretty good.
How NOT To Cook
23.95
Not bad.
James Bond; Casino Royale

I just signed up at Server Intellect and couldn't be more pleased with my Windows Server! Check it out and see for yourself.
We
can use this as an XmlDataSource as normal, but in Visual Studio where
it asks for Transformation file, we can creat a text file with the .xsl
extension and point to it from the Configure Data Source window..
The XSL file will look something like this:
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
>
omit-xml-declaration="yes"
indent="yes"
standalone="yes" />

If you're looking for a really good web host, try Server Intellect - we found the setup procedure and control panel, very easy to adapt to and their IT team is awesome!
The ASPX file shows the difference in using the transformation file with a GridView control:
With Transformation File:
