Hi I have another question about namespaces and taglibs. I could work around the problems in my last question but this time the namespace really matters.
I wish to write a simpletaglib which generates XML in a namespace other than it's own. Is this possible? How do I do it? For example: <xsp:page> <!-- etc --> <mytaglib:makexml\> <!-- etc --> </xsp:page> Gives: <page> <!-- etc --> <tagetnamespace:fragment> <!-- fragment elements --> </tagetnamespace:fragment> <!-- etc --> </page> I would assume this is a common requirement... My thanks in advance Adam -----Original Message----- From: Adam Griffiths [mailto:[EMAIL PROTECTED]] Sent: 20 November 2002 18:01 To: [EMAIL PROTECTED] Subject: A SimpleTaglib and namespaces. Hi all, I'm writing a SimpleTaglib and would really appreciate some comments. I have included example code below to illustrate what I'm doing. I wish to have a tag, <GC:makemaintag/>, expanded into an xml fragment by my taglib. First of all, this is my first taglib (:-), have I got the right idea? Could I do it a better way? Second, I've found that the resulting xml fragment has the xml namespace written in every tag, which is rather unnecessary. Is there a way to get the namespace declared in the parent tag and not in all of it's children? I can live with all the namespaces but seeing as I'm a bit of a perl newbie and a taglib newbie it would be great if you can pass your eyes over my code below. Cheers Adam The xml fragment I wish to build is: <maintag> <item> <title></title> <id></id> <value></value> </item><!-- repeated --> <moreinfo></moreinfo> </maintag> I am using a sub: sub makemaintag: struct{ #see below for code } And this results in this xml being output: <GC:maintag xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";> <GC:moreinfo xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";>these items were created by an xsp</GC:moreinfo> <GC:item xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";> <GC:title xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";>first item</GC:title> <!-- see bellow for complete list --> ############################################## Source code, in more detail ############################################## ______________________________________________ My Test XSP file ______________________________________________ <?xml version="1.0"?> <?xml-stylesheet href="." type="application/x-xsp"?> <?xml-stylesheet href="test.xsl" type="text/xsl"?> <xsp:page xmlns:xsp="http://www.apache.org/1999/XSP/Core"; xmlns:GC="http://xmlns.domain.co.uk/xsp/GC"; language="Perl"> <body> <GC:makemaintag/> </body> </xsp:page> ______________________________________________ My Test Taglib ______________________________________________ ### new # AxKit XSP taglib # Adam Griffiths # 20/11/2002 - v.0.01 ### package AxKit::XSP::GC; use Apache::AxKit::Language::XSP::SimpleTaglib; use vars qw/@ISA $NS $VERSION/; @ISA = ('Apache::AxKit::Language::XSP::SimpleTaglib'); # define the namespace we use $NS = 'http://xmlns.domain.co.uk/xsp/GC'; $VERSION = '0.01'; package AxKit::XSP::GC::Handlers; use strict; sub makemaintag: struct{ return << 'EOF'; my $dynamicvalue='on the fly'; #could be the result of some routine or another my $item1 = { title=>"first item", id=>'232', value=>'static value' }; my $item2 = { title=>"second item", id=>'232', value=>$dynamicvalue }; my @itemlist; push @itemlist, $item1; push @itemlist, $item2; #could push more items onto @itemlist here my $children = { item=> \@itemlist, # \@ gives arrayref moreinfo=>'these items were created by an xsp' }; my $maintag = { maintag=>$children }; #gives: #<maintag> #<item> # <title></title> # <id></id> # <value></value> #</item> #<moreinfo></moreinfo> #</maintag> $maintag; EOF } 1; ______________________________________________ Resulting XML (you may wish to turn line wraping off!) ______________________________________________ <GC:maintag xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";> <GC:moreinfo xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";>these items were created by an xsp</GC:moreinfo> <GC:item xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";> <GC:title xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";>first item</GC:title> <GC:id xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";>232</GC:id> <GC:value xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";>static value</GC:value> </GC:item> <GC:item xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";> <GC:title xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";>second item</GC:title> <GC:id xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";>232</GC:id> <GC:value xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";>on the fly</GC:value> </GC:item> </GC:maintag> ______________________________________________ My prefered resulting XML, can it be done? ______________________________________________ <GC:maintag xmlns:GC="http://xmlns.domain.co.uk/xsp/GC";> <GC:moreinfo>these items were created by an xsp</GC:moreinfo> <GC:item > <GC:title >first item</GC:title> <GC:id>232</GC:id> <GC:value >static value</GC:value> </GC:item> <GC:item> <GC:title>second item</GC:title> <GC:id>232</GC:id> <GC:value>on the fly</GC:value> </GC:item> </GC:maintag> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
