I seem to be having troubles in IE and firefox (with Sarissa - although the example below uses activex msxml) when creating an xsl dom document from a string and using the following xsl from a variable:
<xsl:variable name="widths" select="document('')/*/x:widths"/>
<x:widths>
<width>201</width>
<width>208</width>
<width>102</width>
</x:widths>
<xsl:template match="/">
--[<xsl:value-of select="$widths"/>]--
</xsl:template>
This above code works with an xsl dom document from a file as the browsers know what base-uri to use - however when I do it from a javascript string I think it takes the html document itself as the base-uri (I was getting a malformed xml error saying "</form> does not match starting tag: <input>". This <input> tag is in my html file not in the xsl - I fixed this error by putting closing tags on the input to make it well formed).
When I run the script in a browser I get the following output:
--{ --[]--}--
When I run the script from any xml file with the stylesheet also from a file I get the correct output:
--[ 201 208 102 ]--
When I run a slightly changed xsl in the browser with:
<xsl:variable name="widths" select="document('test.xsl')/*/x:widths"/>
it'll work but that doesn't solve my problem because the dynamic design file will contain the widths. As a last resort I can extract the widths from various places in the design file
question Does anybody know how to set the base-uri for an xml created from a javascript string, or any other way of getting around the problem?
I need to do it from a string as I'm using xslt to render an xml design document to output another xsl document which I then use to process xml docs from the server.
thanks for your help in advance

here's my javascript code for IE:
<span style='font-family:courier'>
<html>
<head>
<script type="text/javascript">
var innerText;
if (!document.all)
innerText = "textContent";
else
innerText = "innerText";
var xmlString = '<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:x="mynamespace">' +
'<xsl:output method="text"/>' +
'<xsl:variable name="widths" select="document(\'\')/*/x:widths"/>' +
'<x:widths>' +
'<width>201</width>' +
'<width>208</width>' +
'<width>102</width>' +
'</x:widths>' +
'<xsl:template match="/">' +
' --[<xsl:value-of select="$widths"/>]--' +
'</xsl:template>' +
'</xsl:stylesheet>';
function parseXml()
{
var xmlDoc = new ActiveXObject('MSXML2.DOMDocument.4.0');
xmlDoc.async=false;
xmlDoc.load("test.xml");
var xslDoc =new ActiveXObject('MSXML2.FreeThreadedDOMDocument.4.0');
xslDoc.async = false;
xslDoc.loadXML(xmlString);
// create XSLTemplate object and compile stylesheet into it
var cache = new ActiveXObject("Msxml2.XSLTemplate.4.0");
cache.stylesheet = xslDoc;
var proc = cache.createProcessor();
proc.input = xmlDoc;
var result = proc.transform();
document.getElementById('content')[innerText]= "--{" + proc.output + "}--";
}
</script>
</head>
<body>
<form>
<input type='button' id="someButton" onClick="parseXml();" value="Change content"/>
<input type='text' name='which' value='1'/>
<div id="content">Content here!</div>
</form>
</body>
</html>
</span>

Sorry, I don't know the answer to this one.
