There are a number of free parsers available for UNIX platforms. The most common is probally the one associated with libxslt2 i.e. xsltproc.
BTW, If your input document is that large and causing the problems you describe, I suggest you use a SAX or SiAX processor instead of a DOM-based processor. If you have access to IEEE Computer Society proceedings, there was an article in the Sept 2008 edition of Computer by Lam, Ding, and Liu on XML Document parsing performance characteristics which gives more information and benchmarks.

xml::libxml::sax::builder5.18
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.
