XML::XPath and removing a node/leaf

Hi there,
I have been looking through the perldoc for XML::XPath to
see how toremove a node but there seems to be no method te
do this. Does anyonehave a recipe for how to do this, or a
link to somewhere thatdescribes how to?Google is not being
very helpful on the matter... :-/
TIA,

You might look for XML:OM::XPat
h in CPAN. You can use DOM for 
adding/removing elements and xpath for fetching them.

you can’t do that with XPath. XPath is purely for locating
(sets
of) nodes. You need a supporting API to *do* something with
the
nodes. In general, using XPath implies using the DOM
(wretched as
it is) to manipulate the tree.

I suggest XML::LibXML – it’s based on libxml2, which is
very
complete in its standards support, is blazing fast, and has
small
memory footprint. No pure-Perl module can hold a candle to
it.
And the Perl bindings are perlish, inasmuch as any DOM API
can be
perlish.

I was looking for the same thing recently, and found some
undocumented
methods in the tests. I.e.

removeChild( $node )
removeAttribute( $attrName )

c.f. http://search.cpan.org/src/MSERGEANT/XML-XPath-1.1
3/t/remove.t

There is a lot of support in XML::XPath for creating and
appending nodes,
which is probably why I expected to find removal there too.
Next time
however, in light of these comments that seem in retrospect
correct, I 
think I'll look elsewhere.

David
