The Syntax

XPathScript follows the basic ASP syntax of introducing code with the <% %> delimiters. Here's a brief example of a fully compatible XPathScript stylesheet:

<html>
 <body>
  <%= 5+5 %>
 </body>
</html>

This simply outputs the value 10 in a HTML document. The delimiters used here are the <%= %> delimiters, which are slightly different in that they send the results of the expression to the browser (or to the next processing stage in AxKit). Of course this example does absolutely nothing with the source XML file which is completely separate from this stylesheet. Here's another example:

<html>
 <body>
  <% $foo = 'World' %>
Hello
  <%= $foo %> !!!
 </body>
</html>

This outputs the text "Hello World !!!". Again, we're not actually doing anything here with our source document, so all XML files using this stylesheet will look identical. This seems rather uninteresting until we discover the library of functions that are accesible to our XPathScript stylesheets for accessing the source document contents.
