Bryan,

Thank you for your high appreciation of the usefulness 
and ease of use of the XPath Visualiser.

Right now the latest drop contains an even enhanced version.
With the new functionality added, the XPath Visualiser 
is more of a full-blown XPath Interpreter, than just the 
node-set browser it was in the previous release.

In addition to XPath expressions that are evaluated to nodesets
the user can now enter expressions that are evaluated to scalars
(number or boolean or string).

Now it's possible not only to find a specific node-set within the
source xml document, but also to obtain its quantitative 
characteristics -- counts, sums, arithmetical and relational 
results, strings, substrings etc.

One good consequence is that info about hidden nodes (not present in
the text of the xml source) can now be obtained in this way.

Once again, thank you for your interest in the XPath Visualiser.

This is a useful tool.  It's easy to set up and use.  

The URL in the note didn't work for me though. Thankfully Dimitre
straightened me out.  I  actually had to go to:

http://www.vbxml.com/downloads/files/xpathvisualiserseptember.zip

to download it.

The XPath Visualiser is an interactive tool that hilights all nodes 
of a user-specified XPath expression's result-nodeset in a colour-coded

collapsible display of an xml source document. 

This tool is very convenient for anyone who is a stylesheet author, 
is interested to learn or just curious about building XPath
expressions. 

The XPath Visualiser can be used in different scenarios:
 1. Composing the exact XPath expression when designing an XSLT
stylesheet. 
 2. As a "nodeset view" in a watch window of an XSLT debugger. 
 3. Learning and playing with XPath expressions. 
 4. As an example how to process completely un-anticipated XML
documents using "push processing". 


The latest version of the XPath Visualiser can be downloaded at 
http://www.vbxml.com/files/downloads/XPathVisualiserSeptember.zip

Requirements: 
  The September release of MSXML 3.0 and IE 5.

The following works with earlier releases of MSXML 3.0, 
but has relatively limited functionality:

Many thanks to Mike Kay -- this work was extremely influenced 
by the continuous help provided in all his answers to my questions.

Also thanks to Johnatan Marsh -- a customised version of his IE
defaultss.xsl stylesheet is the basis for this work. 
Any errors in the customised stylesheet are entirely mine.

I'd greatly appreciate any observations, remarks and suggestions 
for improvement of the functionality and efficiency of the tool.

Thanking you in advance,

Dimitre Novatchev.
