Did you mean use DOMParser to parse the xslt document as well as the
document to be transformed:

    var proc = new XSLTProcessor();
    var xslt_str = "<?xml version='1.0'?>"
    + "<xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform' version='1.0>"
        + "<xsl:output method='html'/>"
        + "<xsl:template match='/test'><p>goodbye!</p></xsl:template>"
        + "</xsl:stylesheet>";
    var xslt = (new DOMParser()).parseFromString(xslt_str, 'application/xml');
    proc.importStylesheet(xslt);

This fails:

    Error: uncaught exception: [Exception... "Component returned
    failure code: 0x80600001 [nsIXSLTProcessor.importStylesheet]"
    nsresult: "0x80600001 (<unknown>)" location: ...

It also fails using text/xml as the MIME type.

Using the method I first outlined:

    var xslt = document.implementation.createDocument("", "", null);
    xslt.innerHTML = "<?xml version='1.0'?>"
    + "<xsl:stylesheet xmlns:xsl='http://www.w3.org/1999/XSL/Transform' version='1.0>"
        + "<xsl:output method='html'/>"
        + "<xsl:template match='/test'><p>goodbye!</p></xsl:template>"
        + "</xsl:stylesheet>";
    proc.importStylesheet(xslt);

Does result in a working stylesheet but I don't get any data.

Using a source document parsed with DOMParser and the working XSLT
doesn't work either.


Do you *know* the DOMParser works with XSLT?

Any more ideas?
