Well, If I understood your message, you want to read a XML file and create
forms, buttons, etc with that information. This is not what XSLT does, 
it just
transform between markup file formats. I think you should wait until Benoît
releases the new Gambas developement version in which you'll be able
to create components with Gambas, and then, from your component, read
XML files and create forms, and other widgets based on the XML file
information at runtime. This will be easy than adding it to the C XSTL 
code (which
uses libxml ( http://www.xmlsoft.org ). This would be the way:

You can XmlReader (or may be XmlDocument when I finish it) to read the
XML file, and modify that XSLT file:

<xsl:for-each select="BUTTONS">
   <xsl:for-each select="./BUTTON" >
       <xsl:value-of select="processor:SETBUTTON(.)" >
           </xsl:value-of> 
       </xsl:for-each>
   </xsl:for-each>


Read and parsed by your component which receives the information from both the XSLT file and
a Form that you pass as parameter, for example:

MyClass. Parse("XslFile.xsl",MyForm)
