1) I try setParameter() and pass null as a first argument. I get exception
("Component returned failure code: 0x80600008
[nsIXSLTProcessor.transformToFragment]") when trasformTo...() method is called.
2) If I call setParameter() and pass namespace
"http://www.w3.org/1999/XSL/Transform" as a first argument then parameter will
not be setted.

It is independent of importStylesheet() method call point.

Reproducible: Always

Are you sure it is not set? Can you try with xsl:copy-of? It seems like you set
it as a stringvalue but you use it as a nodeset.

In the stylesheet, you reference 
<xsl:for-each select="$path">
which expects the non-namespaced parameter "path" to hold a nodeset. That is
not supported for external parameters just yet, that's bug 248025.

xslProcessor.setParameter("http://www.w3.org/1999/XSL/Transform", "path",
"messages/message[@type='error']");

actually sets xsl:path (DONT, please) to a string value. Not a nodeset.

Everything works as expected, besides the fact that we can't pass nodes :-/

Comment 6

[alexander :surkov (:asurkov)]

I can't understand. Why does <xsl:for-each select="$path"> expect nodeset not
string? I guess it is not evident. I expect when I set string parameter then all
parameters entries in xslt is replaced by value of passed string. In this case
we get xslt document in witch value of passed string is located on place of
parameter.

Comment 7

[alexander :surkov (:asurkov)]

In other words I expect from setParameter() method for behaviour like:

var path="messages/message[@type='warning']";
xslDoc.getElementsByTagName("param")[0].setAttribute("select", path);

[Axel Hecht]

http://www.w3.org/TR/xslt#element-for-each says

<xsl:for-each
  select = node-set-expression>

The variable references are not replaced, but they are expressions in their own
sense.
