you can read here:

have
read the introduction (I just found it), and it may help or hinder the

Interesting stuff, looks good!

Subject: [XPL] About XPipes

  About XML Pipes

  I recently wrote a case study for Wrox in which I started building 
an XSLT
framework called XPipes. It is intended as a framework for developing 
web
output quickly, although it incorporates a lot of what I've mentioned 
in
previous posts -- the double pass XSLT processing, the conversion of 
simple
tag/attribute elements into object requests, the definition of more
sophisticated scripts. It's still not simple enough, principally 
because of
namespace limitations, but it's getting there.

  For example, the following is a working XPipes page:
  <!-- sampleDoc.xml -->
  <xp:document xmlns:xp="http://www.vbxml.com/xp">
      <param name="title">My Document</param>
      <param name="author">Kurt Cagle</param>
      <param name="email">cagle@o...</param>
      <param name="user"/>
      <xp:script name="string" 
namespace="http://www.vbxml.com/string"/>
      <xp:body onclick="alert('This is a test!')">
          <h1><out>$title</out></h1>
          <h2><link href="mailto:
{$email}"><out>$author</out></link</h2>
  [Richard Anthony Hein]
  I like this method for output, it looks so intuitive to me, as far 
as XML
gets.

          <var name="sample_text"><p>Hello, #user, this is a sample 
of your
web page.</p></var>
          <out>string:replace_text($sample_text,'#user',$user)</out>
      </xp:body>
  </xp:document>

  If you then pass the following URL:

  http://localhost/xpserver.asp?source=sampleDoc&title=A New 
Page&user=John
Doe

  then the XP page, when doubly parsed will generate as output:

  <html>
      <head>
             <title>A New Page</title>
       </head>
      <body onclick="alert('This is a test!')">
          <h1>A New Page</h1>
          <h2><a href="mailto:cagle@o...">Kurt Cagle</h2>
          <p>Hello, John Doe, this is a sample of your web page.</p>
      </body>
  </html>

  It gets more complex than this -- I have tables, forms, and treeview
controls that all work within this paradigm as well -- but you get the
general idea.
