Re: [xsl] XPath equivalent to xsl:apply-templates?

Hi Roger,

be represented in XPath. Okay, Dimitre, what's the XPath equivalent of
xsl:apply-templates?]

I don't remember ever making such a statement. ?!?

And in my work it has never been raised as a problem to represent the
generic <xsl:apply-templates> in pure Xpath.

Perhaps, if we have a more understandable and simple example, we could
understand what it exactly is that you need, and why you need it in the
first place?

Once again: while it may be possible in XPath to implement function
dispatch based on arguments' type and context, I don't see why someone
would need to do this. Suppose we could write an XSLT processor in pure
XPath, then the result will still be essentially XSLT with its fundamental
principles and ideas.

Thanks,
Dimitre
