Client-side XSLT containing import/include statements does not work in Firefox

Hi,

I want to perform XSL transformations in Firefox (v1.0.3) and IE (v6) using 
JavaScript. My problem is with the XSL scripts that contain <xsl:import ...> 
or <xsl:include ...> statements. Firefox stalls indefinitely when it calls 
importStylesheet(...) on a script that contains one or both of these 
statements.  The code works well on IE and I get the expected results, but 
not on Firefox. Does anyone know what I need to do to get this working?


Thank you,
Daniel

Here is my Javascript code:

function buildPage(iXmlStr, iXslStr) {
    ...
    var xmlDoc = getDom(iXmlStr);
    var xslDoc =  getDom(iXslStr);
    html = xslt(xmlDoc, xslDoc);
    ...
};

function getDom(iXmlStr) {
    if (isIE) {
        var xmlDoc = new ActiveXObject("MSXML2.DOMDocument.3.0");
        xmlDoc.loadXML(iXmlStr);
        return xmlDoc;
    }
    return (new DOMParser()).parseFromString(iXmlStr, "text/xml");
};

function xslt(iXmlDoc, iXslDoc) {
    var html = null;
    try {
        if (isIE) {
            iXmlDoc.async = false;
            iXmlDoc.resolveExternals = false;
            iXslDoc.async = false;
            iXslDoc.resolveExternals = false;
            html = iXmlDoc.transformNode(iXslDoc);
        }
        else {
            var xsltProc = new XSLTProcessor();
            xsltProc.importStylesheet(iXslDoc);
            var resultDoc = xsltProc.transformToDocument(iXmlDoc);
            var xmlSerial = new XMLSerializer;
            html = xmlSerial.serializeToString(resultDoc);
        }
    } catch (e) {
        // Do something
    }
    return html;
};


Here is a sample XSL file:

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:fo="http://www.w3.org/1999/XSL/Format">
    <xsl:import href="http://www.myDomain.com/detailForm.xsl"/>
</xsl:stylesheet>
