XML::RSS::Parser 4.0

XML::RSS::Parser is a liberal object-oriented parser for RSS feeds. SYNOPSIS #!/usr/bin/perl -w use strict; use XML::RSS::Parser; use FileHandle; my $p = XML::RSS::Parser->new; my $fh = FileHandle->new(/path/to/some/rss/file); my $feed = $p->parse_file($fh); # output some values my $feed_title = $feed->query(/channel/title); print $feed_title->text_content; my $count = $feed->item_count; print " ($count)n"; foreach my $i ( $feed->query(//item) ) { my $node = $i->query(title); print .$node->text_content; print "n"; } XML::RSS::Parser is a lightweight liberal parser of RSS feeds. This parser is "liberal" in that it does not demand compliance of a specific RSS version and will attempt to gracefully handle tags it does not expect or understand. The parsers only requirements is that the file is well-formed XML and remotely resembles RSS. Roughly speaking, well formed XML with a channel element as a direct sibling or the root tag and item elements etc. There are a number of advantages to using this module then just using a standard parser-tree combination. There are a number of different RSS formats in use today. In very subtle ways these formats are not entirely compatible from one to another. XML::RSS::Parser makes a couple assumptions to "normalize" the parse tree into a more consistent form. For instance, it forces channel and item into a parent-child relationship. For more detail see "SPECIAL PROCESSING NOTES". This module is leaner then XML::RSS -- the majority of code was for generating RSS files. It also provides a XPath-esque interface to the feeds tree. While XML::RSS::Parser creates a normalized parse tree, it still leaves the mapping of overlapping and alternate tags common in the RSS format space to the developer. For this look at the XML::RAI (RSS Abstraction Interface) package which provides an object-oriented layer to XML::RSS::Parser trees that transparently maps these various tags to one common interface. XML::RSS::Parser is based on XML::Elemental, a a SAX-based package for easily parsing XML documents into a more native and mostly object-oriented perl form..
