It is with great relish that I announce that XML::XPathScript v1.47 is on its
way to a CPAN mirror near you.
What is new in this release:
* template tag attributes can now be functions as well as strings.
For example,
$template->set( 'foo' => { testcode => sub {
my( $n, $t ) = @_;
my $name = $n->findvalue( 'name()' );
$t->set({ pre => transfurbicate( $name ) });
return $DO_SELF_AND_CHILDREN;
}
} );
can now be written
$template->set( 'foo' => { pre => sub {
my( $n, $t ) = @_;
my $name = $n->findvalue( 'name()' );
return transfurbicate( $name );
}
} );
* The 'content' template attribute, which associates template elements to
mini-stylesheets.
E.g., the code
<%
$template->set( 'foo' => {
pre => '<newFoo foo_myattr="[EMAIL PROTECTED]" >',
post => '</newFoo>',
action => 'bar', # only process 'bar' node children
} );
%>
can now be written
<%
$template->set( 'foo' => { content => <<'END_CONTENT' } );
<newFoo foo_myattr="[EMAIL PROTECTED]" > <%# look Ma, we
interpolate! %>
<%~ bar %> <%# only process bar children %>
</newFoo>
END_CONTENT
%>
<%# process all foo's %>
<%~ //foo %>
Or, to be more easy on the eye, we can use the short-hand version:
<%@ foo
<newFoo foo_myattr="[EMAIL PROTECTED]" > <%# look Ma, we interpolate!
%>
<%~ bar %> <%# only proces bar children %>
</newFoo>
%>
<%# process all foo's %>
<%~ //foo %>
* B::XPath now a supported DOM tree. Bored with transforming XML documents?
How about transforming Perl Optrees? :-)
use B::XPath;
use XML::XPathScript;
sub guinea_pig {
my $x = shift;
print "oink oink " x $x;
}
my $xps = XML::XPathScript->new;
$xps->set_dom( B::XPath->fetch_root( \&guinea_pig ) );
$xps->set_stylesheet( '<%~ //print %>' );
print $xps->transform;
Joy,
