Top Forums Shell Programming and Scripting How to improve the performance of parsers in Perl? Post 302515969 by fpmurphy on Thursday 21st of April 2011 09:04:32 AM

Unless you need the complete document DOM in memory, a SAX (Sequential Access XML) parser will nearly always be faster. Whereas the DOM operates on the document as a whole, SAX parsers operate on each piece of the XML document sequentially. Even better would be StAX (Streaming API for XML) which is a newer API for pull-parsing of XML

Perl has several SAX modules but I do not see any StAX modules.

NAME
MKDoc::XML::Decode - Expands XML entities SYNOPSIS
use MKDoc::XML::Decode; my $decode = new MKDoc::XML::Decode qw/xml xhtml numeric/; # $xml is now "Chris' Baloon" my $xml = MKDoc::XML::Decode->process ("Chris&apos; Baloon"); SUMMARY
MKDoc::XML::Decode is a very simple module with pluggable entity decoding mechanism. At the moment there are three modules: xml - Decodes &apos; &quot; &gt; &lt; and &amp; xhtml - Decodes XHTML entities such as &eacute; numeric - Decodes numeric entities such as &#65; That's it. This module and its counterpart MKDoc::XML::Encode are used by MKDoc::XML::Dumper to XML-encode and XML-decode litterals. API
my $decode_object = new MKDoc::XML::Decode (@modules); Constructs a new decode object using the modules specified in @modules. my $decoded = $decode_object->decode ($stuff); Decodes $stuff and returns it into $decoded. Any entity which is not recognized will be returned as is but will trigger a warning. AUTHOR
