Understanding XSLT transformations: Your Own `XML Transformation Utility` - Testing further with different types of XML
(Page 6 of 6 )

The above samples, which I gave, are quite simple.  Let us further extend the same “Hello World” example with different types of XML. 

Let us consider the following modifications for the same XML document:

<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="Sample1.xsl"?>
<greeting>
            <Hello>Hello, World!</Hello>
</greeting>

If you transform the above XML with same XSL as above, you will still receive the same output (or the same transformation).  You should be clear that “.” (dot) refers to the text present in the current node (of the context) along with all the other nodes nested within the same context.  That is why, even though “Hello World” is nested in another element, we could still get it out.

For that matter, if you modify the same XML to the following:

<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/xsl" href="Sample1.xsl"?>
<greeting>
            Hello, World1!
            <Hello>Hello, World2!</Hello>
            <Hello>Hello, World3!</Hello>
</greeting>

There is no doubt that you get all the three messages in bold.

Remarks

Even though I used a simple example for XSLT transformation, XSLT has its own depth.  I shall now and then contribute articles about XSLT.  So, do not forget to check this website frequently.  For all of my future articles on XSLT, you can work with the same tool (or utility) I provided along with this article.

The utility that we developed now, is primarily a basic utility for beginners to test their XSLT expertise and is not intended for any production usage.  If you have any better ideas for developing the utility, please do not forget to post about them.

The entire demonstration solution has been developed using Visual Studio 2005 Professional Edition on Windows Server 2003 Standard Edition. Note that I didn’t really test the solution on any of the other versions/editions related to the similar suite of Microsoft products.
