Hello

I'm a french studend so please excuse my english.

I'm new to XForms and I have a problem when trying to get XForm with a
client-side transformation in Javascript.

* Environnement :
	- IE 6
	- MSXML 4.0
	- FormsPlayer or XForms Processor Control (IBM)

* Process
	- an xml document with business data (without any presentation data)
	is transformed with an XSL stylesheet (with the presentation data :
table, forms element)
	- trandformation is done using a javascript function called at the onLoad
event.
	- result of transformation is then put in the html document still using
javascript


Have a look on the existing source :

*** page.html***
<html>
	<head>
		<script language="JavaScript" type="text/javascript">
			function init(){
				//*// Load XML
				var xml = new ActiveXObject("Msxml2.DOMDocument.4.0")
				xml.async = false;
				xml.resolveExternals = false;
				xml.validateOnParse = false;
				xml.load("ctx.xml");

				//*// Load XSL
				var xsl = new ActiveXObject("Msxml2.DOMDocument.4.0");
				xsl.async = false;
				xsl.load("InstanceNewCF.xsl");

				// Transformation
				document.getElementById("NouvelleInstance").innerHTML =
xml.transformNode(xsl);
			}
		</script>
	</head>
	<body onLoad="init();">
		<div id="NouvelleInstance">
		</div>
	</body>
</html>

*** ctx.xml (sample)***
<?xml version="1.0" encoding="ISO-8859-1"?>
<ADT>
	<ID></ID>
	<L/>
	<ETA-ID>1</ETA-ID>
	<ETA-L>Ouvert</ETA-L>
	<ID-CRT/>
	<PRN-CRT/>
	<NOM-CRT/>
	<ID-STR-CRT/>
	<ID-AG/>
	<L-CRT-AG/>
	<L-LG-AG>1234</L-LG-AG>
</ADT>

*** InstanceNewCF.xsl (sample) ***
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet
	xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">
<xsl:output method="html" omit-xml-declaration="yes" indent="yes"/>

<xsl:template match="ADT">
	<!-- Description -->
	<table>
		<colgroup>
			<col width="45%"></col>
			<col width="30%"></col>
			<col width="25%"></col>
		</colgroup>
		<tr id="TRApporteur">
		<xsl:choose>
			<xsl:when test="//TPO-APP[. >= 100]">
				<td>
					<label class="obligatoire">Mandataire : </label>
					<input id="INIDApporteur" name="value"><xsl:value-of
select="ID-AG"/></xsl:attribute></input>
				</td>
			</xsl:when>
			<xsl:otherwise>
					<td>
						<label class="obligatoire">Mandataire : </label>
						<span id="IdAgence" tabindex="1"><xsl:value-of
select="ID-AG"/></span>&#160;
						<span id="SELLibLongAgence" tabindex="2"><xsl:value-of
select="L-LG-AG"/></span>
					</td>
			</xsl:otherwise>
		</xsl:choose>
		</tr>
	</table>
</xsl:template>


What I want to do is use xforms with this existing architecture :
- create the xforms model in the xslt using <xsl:copy-of select="."/> in
the xsl:template matching ADT node
- use xforms user interface element instead html forms

The proble is it doesn't work :
	- code is not interpreted with the IBM's XForms Processor Control
	- with FormsPlayer, if the model is hard-coded in the HTML page, Xforms
controls are display but they don't bind to the model (even if I use
binding.

It seems the XForms code *must* be write at the page load. Is there any
method to load the plugin dynamically ?

Does anybody have this problem ? Is it possible to do, with the actual
technologie, a client-side transformation using XSLT to produce a valide
XForms code who will be interpreted by an Xforms plugin ??


Thanks for your help

Best Regards

Claude
