RE: [xsl] Dynamicaly applying templates from a node-set containing xpath values - with msxml parser

["Matthieu Ricaud" <matthieu.ricaud@xxxxxxx>]

Hi Ragulf,
the <xsl:value-of select="dyn:evaluate($root,$var)"/> with <xsl:variable
name="root" select="/">
works perfectly, in my real problem also !
It looks so obvious now you said it !
Thanks a lot for this good "couple of thoughts" and your explanation,
Have a nice day,
cheers,
Matthieu.

Hi again Matthieu,

I have been rereading your mail here, and have a couple of thoughts.

Here, I think the problem is, that you are not in the domain of the
document, but rather of the nodeset (contained in
msxsl:node-set($NodeSetXpathNode)/xpath). I think you will have to
shift the contents to the document. Perhaps something link
dyn:evaluate($root,$var)"/> where $root is the root element in the
input document (<xsl:variable name="root" select="/">).

If this works, then the same applies to your real problem.

The select="." does not select a text() node, but rather the current
node, which will be the different xpath elements in the nodeset.
Therefore there is a vast difference of writing:
<xsl:variable name="foo" select="'bar'"/> <!-- String with value "bar" -->
<xsl:variable name="foo" select="bar"/> <!-- Element called "bar" -->
That you have when you say select="." is essentially the same as the
latter of the two. Therefore the string conversion is needed.

See first part of mail.

I hope this is of some help
