hi,
I have been released RefleX, an application that uses intensively VFS :
RefleX is available for download here :
http://reflex.gforge.inria.fr/
RefleX is a Java tool that allow to design programs entirely in XML.
XML programs -called also Active Tags programs- are using intensively
XPath to cross objects other than XML objects.
for example : a file object
a file object exposes its properties as XML content and attributes, so
it is easy to select a set of files, for example :
-consider that one creates a property named myDir which value is given
by the XPath function :
io:file( 'file:///path/to/repository ')
-then you can apply other XPath expressions on it :
$myDir/@io:exists
$myDir/@io:is-file
$myDir/@io:is-directory
$myDir/@io:length
$myDir/@io:encoding
$myDir/@io:path
name( $myDir )
$myDir//*
to select the files and directories in the entire subtree
$myDir//[EMAIL PROTECTED]:is-file]
to select the files in the entire subtree
$myDir//[EMAIL PROTECTED]:[EMAIL PROTECTED]:extension='xml']
to select the XML files in the entire subtree
$myDir/..
to select the parent directory, if any
$myDir/../@io:length
etc...
to use single files and a set of files, the following active sheet (that
is to say an Active Tags program) shows how to transform all XML files
from a repository to HTML :
<xcl:active-sheet
xmlns:io="http://www.inria.fr/xml/active-tags/io";
xmlns:xcl="http://www.inria.fr/xml/active-tags/xcl";
>
<xcl:logic>
<!-- the same stylesheet for all XML files -->
<xcl:parse-stylesheet name="xslt"
source="file:///path/to/myStylesheet.xsl"/>
<xcl:set name="myXMLFiles"
value="{io:file( '/path/to/my/xml/docs'
)//[EMAIL PROTECTED]:[EMAIL PROTECTED]:extension='xml']}"/>
<xcl:for-each name="file" select="{$myXMLFiles}">
<xcl:parse name="xml" source="{$file}"/>
<xcl:transform name="html" output="{substring-before(
$file/@io:path, '.xml' )}.html"
source="{$xml}" stylesheet="{$xslt}"/>
</xcl:for-each>
</xcl:logic>
</xcl:active-sheet>
as the files are handled by VFS, all the file systems supported are also
available in RefleX ; for its own functioning, RefleX also provides some
add-ons :
the xmldb scheme to access to files that are stored within XML native
databases :
xmldb:provider://user:[EMAIL PROTECTED]:port/path/to/file.xml
the ldap scheme
the web scheme, which allows to access to files within a servlet :
web:///WEB-INF/web.xml
Have fun !
