[plt-scheme] Web programming .

  Sorry, forgive me not able to clarify more on this topic . Here's the 
piece of code from the Genshi template file :
  <py:match path="body" once="true" buffer="false"><body>
    </body> </py:match>
  The above code is just instructing the template engine to *select* the 
text content of node "body" from the XHTML streams.  That's the one I 
was asking actually.  There's a difference between Genshi and PLT scheme 
web template from my point of view , the former separates the template 
macros and the real content streams ,while the latter  combines the 
template macros (S-expressions) with the content. As suggested by Jay, I 
could use SXML/SXPATH library to parse the XHTML content and select 
those nodes which I'm interested in. Yeah, this is possible , but I 
havn't used that yet,  on a quick read of its tutorial 
(http://modis.ispras.ru/Lizorkin/sxml-tutorial.html) , I probably need 
to obtain a SXML representation of a document which means the template 
file should be expanded first (using @include-template) and then parse 
it using SXML parser into a SXML document before I can use SXPath on it, 
am I right ? Or is there a way to do it in template file itself ? Thanks.
