下载源码包 libxml-rsslite-perl:
XML::RSSLite 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.
