Modify a DOM Tree and transform it after

[Anne-Claire Trommenschlager <An...@steria.ch>]

Hi,

I have a big doubt. Is it possible to parse an xsl file, to modify it in
adding some nodes and then with an XML file to transform it in an HTML file.
When I try, it seems that it doesn't evaluate what I added in the xsl file. 
I add :
Element elt = xslDoc.createElement("TD");
toto.appendChild(elt);
Element elt1 = xslDoc.createElement("xsl:element");
elt.appendChild(elt1);
elt1.setAttribute("name", "FONT");			
Element elt2 = xslDoc.createElement("xsl:attribute");
Text txt2 = xslDoc.createTextNode("#FFFFFF");
elt2.appendChild(txt2);
elt1.appendChild(elt2);
elt2.setAttribute("name", "Color");			
Element elt3 = xslDoc.createElement("xsl:attribute");
Text txt3 = xslDoc.createTextNode("Verdana");
elt3.appendChild(txt3);
elt1.appendChild(elt3);
elt3.setAttribute("name", "FACE");
Element elt4 = xslDoc.createElement("xsl:attribute");
Text txt4 = xslDoc.createTextNode("2");
elt4.appendChild(txt4);
elt1.appendChild(elt4);
elt4.setAttribute("name", "SIZE");
Element elt5 = xslDoc.createElement("xsl:value-of");
elt1.appendChild(elt5);
elt5.setAttribute("select", "$param6");


And in my HTML file I have :
<xsl:element name="FONT">
<xsl:attribute name="Color">#FFFFFF</xsl:attribute>
<xsl:attribute name="FACE">Verdana</xsl:attribute>
<xsl:attribute name="SIZE">2</xsl:attribute>
<xsl:value-of select="$param6"></xsl:value-of>
</xsl:element>

It is exactly what I want to add in my xsl file.

Please can give me an answer or say me how I can do ?
Thanks
Anne-Claire
