NAME
XML::RSS::JavaScript - serialize your RSS as JavaScript
SYNOPSIS
use XML::RSS::JavaScript;
my $rss = XML::RSS::JavaScript->new();
$rss->channel(
title => 'My Channel',
link => 'http://my.url.com',
description => 'My RSS Feed.'
);
$rss->add_item(
title => 'My item #1',
link => 'http://my.item.com#1',
description => 'My first news item.'
);
$rss->add_item(
title => 'My item #2',
link => 'http://my.item.com#2',
description => 'My second news item.'
);
# save rss
$rss->save( '/usr/local/apache/htdocs/myfeed.xml' );
# save identical content as javascript
$rss->save_javascript( '/usr/local/apache/htdocs/myfeed.js');
DESCRIPTION
Perhaps you use XML::RSS to generate RSS for consumption by RSS parsers.
Perhaps you also get requests for how to use the RSS feed by people who
have no idea how to parse XML, or write Perl programs for that matter.
Enter XML::RSS::JavaScript, a simple subclass of XML::RSS which writes
your RSS feed as a sequence of JavaScript print statements. This means
you can then write the JavaScript to disk, and a users HTML can simply
*include* it like so:
<script language="JavaScript" src="/myfeed.js"></script>
What's more the javascript emits HTML that can be fully styled with CSS.
See the CSS examples included with the distribution in the css
directory.
<html>
<head>
<link rel="stylesheet" type="text/css" href="/css/rollover1.css">
</head>
<body>
Your content here...
<script language="JavaScript" src="http://my.feed.com//myfeed.js"></script>
</body>
</html>
INSTALLATION
perl Makefile.PL
make
make test
make install
METHODS
save_javascript()
Pass in the path to a file you wish to write your javascript in.
Optionally you can pass in the maximum amount of items to include from
the feed and a boolean value to switch descriptions on or off (default:
on).
# save all the content
save_javascript( '/usr/local/apache/htdocs/rss/myfeed.js' );
# no more than 10 items:
save_javascript( '/usr/local/apache/htdocs/rss/myfeed.js', 10 );
# save all items without descriptions:
save_javascript( '/usr/local/apache/htdocs/rss/myfeed.js', undef, 0 );
as_javascript()
as_javascript will return a string containing javascript suitable for
generating text for your RSS object. You can pass in the maximum amount
of items to include by passing in an integer as an argument and a
boolean value to switch descriptions on or off (default: on). If you
pass in no argument you will get the contents of the entire object.
$js = $rss->as_javascript();
save_json( )
Pass in the path to a file you wish to write your javascript in.
Optionally you can pass in any options that would normally get passed to
"as_json".
as_json( )
as_json will return a string containing json suitable for generating
text for your RSS object. You can pass in the maximum amount of items to
include by passing in an integer as an argument. If you pass in no
argument you will get the contents of the entire object. You can also
pass in the name of the JSON object (default: RSSJSON).
MORE EXAMPLES
Perhaps you want to get an existing RSS feed, suck it in, and write it
out as JavaScript for easy consumption.
use XML::RSS::JavaScript;
use LWP::Simple;
my $xml = get( 'http://slashdot.org/slashdot.rss' );
my $rss = XML::RSS::JavaScript->new();
$rss->parse( $xml );
print $rss->as_javascript();
