NAME

       XML::RSSLite - lightweight, "relaxed" RSS (and XML-ish) parser

SYNOPSIS

         use XML::RSSLite;

         . . .

         parseRSS(\%result, \$content);

         print "=== Channel ===\n",
               "Title: $result{'title'}\n",
               "Desc:  $result{'description'}\n",
               "Link:  $result{'link'}\n\n";

         foreach $item (@{$result{'item'}}) {
         print "  --- Item ---\n",
               "  Title: $item->{'title'}\n",
               "  Desc:  $item->{'description'}\n",
               "  Link:  $item->{'link'}\n\n";
         }

DESCRIPTION

       This module attempts to extract the maximum amount of content from available documents,
       and is less concerned with XML compliance than alternatives. Rather than rely on
       XML::Parser, it uses heuristics and good old-fashioned Perl regular expressions. It stores
       the data in a simple hash structure, and "aliases" certain tags so that when done, you can
       count on having the minimal data necessary for re-constructing a valid RSS file. This
       means you get the basic title, description, and link for a channel and its items.

       This module extracts more usable links by parsing "scriptingNews" and "weblog" formats in
       addition to RDF & RSS. It also "sanitizes" the output for best results. The munging
       includes:

       Remove html tags to leave plain text
       Remove characters other than 0-9~!@#$%^&*()-+=a-zA-Z[];',.:"<>?\s
       Remove leading whitespace from URIs
       Use <url> tags when <link> is empty
       Use misplaced urls in <title> when <link> is empty
       Exract links from <a href=...> if required
       Limit links to ftp and http(s)
       Join relative item urls (beginning with / or #) to the site base

   EXPORT
       parseRSS($outHashRef, $inScalarRef)
           $inScalarRef is a reference to a scalar containing the document to be parsed, the
           contents will effectively be destroyed. $outHashRef is a reference to the hash within
           which to store the parsed content.

   EXPORTABLE
       parseXML(\%parsedTree, \$parseThis, 'topTag', $comments);
           parsedTree - required
               Reference to hash to store the parsed document within.

           parseThis  - required
               Reference to scalar containing the document to parse.

           topTag     - optional
               Tag to consider the root node, leaving this undefined is not recommended.

           comments   - optional
               false will remove contents from parseThis
               true will not remove comments from parseThis
               array reference is true, comments are stored here

   CAVEATS
       This is not a conforming parser. It does not handle the following

       •

             <foo bar=">">

       •

             <foo><bar> <bar></bar> <bar></bar> </bar></foo>

       •

             <![CDATA[ ]]>

       •

             PI

       It's non-validating, without a DTD the following cannot be properly addressed

       entities
       namespaces
           This may or may not be arriving in some future release.
