RE: Dynamic dispatch of functions/templates (was match

I think I shall have a hard time explaining the use case without writing
stretching the patience of this list.
Your idea is interesting.

<xsl:variable name="temp">
<xsl:for-each select="text()"><xsl:value-of select="."/></xsl:for-each>
</xsl:variable>
<xsl:apply-templates select="$temp/text()"/>


Question: will this preserve the context in $temp ?
That is, suppose I'm in a template like

<xsl:template match="/FOO/BAR">

Then execute the above.
Would it match only 

<xsl:template match="/FOO/BAR/text()"> 

And match it only once ?

?

(say and not

<xsl:template match="/SPAM/BAR/text()">

)

?

Also it *looks like* $temp above becomes a sequence, not a single text node
???
(Or am I reading too much XQuery into this ?)


Thanks for your patience.

It sounds as if there's a back-story to this one which perhaps I should 
have been following, but on the face of it, you can simply do

<xsl:variable name="temp">
<xsl:for-each select="text()"><xsl:value-of select="."/></xsl:for-each>
</xsl:variable>
<xsl:apply-templates select="$temp/text()"/>

perhaps with a mode.

I don't really follow the logic of how your stated requirement leads to 
a need for dynamic despatch.
