Here's the piece of code from the Genshi template file :   <py:match path="body" once="true" buffer="false"><body>     ${select('*|text()')}     </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 (<a class="moz-txt-link-freetext" href="http://modis.ispras.ru/Lizorkin/sxml-tutorial.html">http://modis.ispras.ru/Lizorkin/sxml-tutorial.html</a>) , 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.

Of course I will take the stabs at writing pieces of prototype and ask here for review. As currently I'm still on the way to fully understand and practice with the powerful PLT scheme web framework by means of building up my blog service , the quick follow up in this topic is just a curious wonder and hope not offending the underlying laws  of this mailing list. I really want to contribute to this great community and be able to help others in exchange to the huge helps from here, but as you know my numb brain just tells me you should dig in it before you give any output ,as emphasized by you.  So thanks anyway , I'll see what I would help in the future.

But I just wonder any plan to continue to extend the powerness of Plt scheme web framework ? Like provide XPath select support in current HTML template system which I've been using  in  Genshi ( a python template component used in Trac (trac.edgewall.org) ? thanks . Nevo Assuming it works the way most other development in PLT has seemed to work, here's all you need to do: Step 1. Find a student who wants a Master's or Ph.D. in Computer Science. Step 2. Interest him/her in what you want. Step 3. Get him/her to interest a member of the PLT group as an advisor. Step 4. Wait for the goodies. :-) But seriously, I'm working with some of my (high school) students on a couple of PLT web apps and we're seeing things we wish we had and taking stabs at putting them together. If you can give examples of the kind of functionality you want and take stabs at writing parts of the code, this mailing list is incredibly good about helping you along. As someone who's gotten huge amounts of help on this list in exchange for a mere pittance of very basic help for the few people even more clueless than himself, my suggestion is dig in, start writing, ask for help, and before you know it, you'll have what you always wanted.
