Hi Eric, I was able to convert XML to VM file using turbine's TurbineXSLTService. The Screen class code, xml and xsl file ares in the attached docuemnts. However I have no idea how I can populate the components when VM file is displayed. I would like to take the approach you sugeested but I have not used DOM4J before, can you send me sample code how to go about.
regards Keshava Murthy.

<?xml version="1.0" encoding="UTF-8" ?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";> <!-- This version of prot.xsl converts a xml document into HTML with proper controls in the correct places. If a field is found in 'methods', it checks whether a TB or a CB or a LBshould be called - and inserts the correct control However, it does not choose the contents in the control to be displayed. i.e. all comboboxes have the same content. All textboxes have the same content. This version also names the control widgets as per the name attribute defined in the source XML. Additionally, for input samples, the XSL makes a table and puts 2 listboxes and 2 buttons there. The generation of this is STATIC. i.e., whenever it finds an element with name="sample" inside the element "materials", the table with the contents are displayed. IT DOES NOT MATTER what control type is defined in the XML, the xslt produces the same output!! --> <xsl:template match="/"> <html> <body> <form name ="protocol" method ="post" action ="$link.setPage("Protocol.vm").setAction("SQLProtocol")" > <h2>Protocol name:</h2> <xsl:apply-templates select="/protocol/name" /> <h3>Materials</h3> <xsl:apply-templates select="/protocol/materials" /> <h3>Methods</h3> <xsl:apply-templates select="/protocol/methods" /> </form> </body> </html> </xsl:template> <xsl:template match="name"> <xsl:value-of select="." /><p/> </xsl:template> <!-- Template to fill in the materials --> <xsl:template match="materials"> <h4>Solutions</h4> <xsl:for-each select="solution"> <xsl:for-each select="*"> <xsl:call-template name="chooser1"/> <!-- find out whether a static or control field is to be output --> </xsl:for-each> </xsl:for-each> <h4>Solvents</h4> <xsl:for-each select="solvent"> <xsl:for-each select="*"> <xsl:call-template name="chooser1"/><!-- find out whether a static or control field is to be output --> </xsl:for-each> </xsl:for-each> <xsl:for-each select="other"> <h4>Other materials </h4> <xsl:for-each select="*"> <xsl:call-template name="chooser1"/><!-- find out whether a static or control field is to be output --> </xsl:for-each> </xsl:for-each> <xsl:for-each select="media"> <xsl:for-each select="*"> <xsl:call-template name="chooser1"/><!-- find out whether a static or control field is to be output --> </xsl:for-each> </xsl:for-each> <xsl:for-each select="sample"> <!-- This is a static template which outputs a table with 2 lb's and 2 buttons. --> <h4>Input Samples</h4> <table><tr> <td nowrap="true"><select name="select" size="10" multiple="true" style="width:150px;"> <option>Sample1</option> <option>Sample3</option> <option>Sample4</option> <option>Sample6</option> </select></td> <td align="center" valign="middle" nowrap="true"> <table width="70"> <tr> <td><input type="button" name='Submit4' value='Add'></input></td> </tr> <tr> <td><input type="button" name='Submit5' value='Remove'></input></td> </tr> </table> </td> <td nowrap="true"><select name="select2" size="10" style="width:150px;"> <option>Sample2</option> <option>Sample5</option> </select></td> </tr></table> <!-- <xsl:call-template name="cb"/> <input type="submit" name="Submit4" value="Add" style="width:70px;"> <xsl:call-template name="lb"/><p/> --> </xsl:for-each> </xsl:template> <xsl:template name="samples"> <xsl:for-each select="*"> Input Samples <xsl:call-template name="cb"/> <xsl:call-template name="lb"/><p/> </xsl:for-each> </xsl:template> <!-- Template to fill in methods--> <xsl:template match="methods"> <xsl:apply-templates select="line"/> </xsl:template> <!-- Template to fill in lines in the method--> <xsl:template match="line"> <p/> <xsl:value-of select="@ln_no"/><xsl:text>. </xsl:text> <xsl:for-each select="*"> <xsl:call-template name="chooser"/> </xsl:for-each> </xsl:template> <!-- chooser template Find out what kind of element has been encountered - static or control widget.
