Petal 2.19

Petal is a Perl Template Attribute Language - TAL for Perl!

SYNOPSIS

in your Perl code:

use Petal;
my $template = new Petal (foo.xhtml);
print $template->process (bar => BAZ);

in foo.xhtml

< html xmlns:tal="http://purl.org/petal/1.0/" >
< body tal:content="bar" >Dummy Content< /body >
< /html >

and you get something like:

< html >
< body >BAZ< /body >
< /html >

SUMMARY

Petal is a XML based templating engine that is able to process any kind of XML, XHTML and HTML.

Petal borrows a lot of good ideas from the Zope Page Templates TAL specification, it is very well suited for the creation of WYSIWYG XHTML editable templates.

The idea is to further enforce the separation of logic from presentation. With Petal, graphic designers can use their favorite WYSIWYG editor to easily edit templates without having to worry about the loops and ifs which happen behind the scene.

NAMESPACE

Although this is not mandatory, Petal templates should include use the namespace http://purl.org/petal/1.0/. Example:

< html xml:lang="en"
lang="en"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:tal="http://purl.org/petal/1.0/" >

Blah blah blah...
Content of the file
More blah blah...
< /html >

If you do not specify the namespace, Petal will by default try to use the petal: prefix. However, in all the examples of this POD well use the tal: prefix to avoid too much typing.
