Hello everyone,
I'm facing some troubles customizing the SPARQL endpoint's html page
of a Virtuoso Open Source 6.1 I have on a remote ubuntu 12.04.2
machine.
The goal of this customization is to add some links under the
<textarea> element a user can click in order to change its content
with some example SPARQL queries.
I followed what's listed here:
http://docs.openlinksw.com/virtuoso/rdfsparql.html#rdfsupportedprotocolendpointuricustm
I wrote an XSLT (see attachment) that basically creates a copy of the
original VOS SPARQL endpoint's html page adding some code in the
<style> and <script> html elements, I copied the VOS SPARQL endpoint's
html source in a .html file, and launched my XSLT against it. I piped
the result in another .html file and tried to display it on my
machine's browser.
It works: it reads the CSS, modifies the textarea, and adds the links.
Thus, I placed this XSLT on a remote machine, and I issued the command
in the isql-vt console giving it the address where the XSLT resides,
reloaded the endpoint page, and waited.
It took nearly 5 minutes, but after that the endpoint does not show up
correctly: the CSS seems to be ignored, and the whole html page
displayed is just its text content.
What am I missing?
Do I have to change something in the XSLT?
Thank you
Andrea
