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.

XML::LibXML::SAX::Builder(3) User Contributed Perl Documentation XML::LibXML::SAX::Builder(3)
NAME
XML::LibXML::SAX::Builder - Building DOM trees from SAX events.
SYNOPSIS
use XML::LibXML::SAX::Builder;
my $builder = XML::LibXML::SAX::Builder->new();
my $gen = XML::Generator::DBI->new(Handler => $builder, dbh => $dbh);
$gen->execute("SELECT * FROM Users");
my $doc = $builder->result();
DESCRIPTION
This is a SAX handler that generates a DOM tree from SAX events. Usage is as above. Input is accepted from any SAX1 or SAX2 event
generator.
Building DOM trees from SAX events is quite easy with XML::LibXML::SAX::Builder. The class is designed as a SAX2 final handler not as a
filter!
Since SAX is strictly stream oriented, you should not expect anything to return from a generator. Instead you have to ask the builder
instance directly to get the document built. XML::LibXML::SAX::Builder's result() function holds the document generated from the last SAX
stream.
