Multithreading in reading file

Dear all,

I am having a huge XML file, as below structure
<EMPLOYEE>
<RECORD id =aaa>
<Salary>99999</Salary>
<section>ssss</section>
</RECORD>
<RECORD id =bbb>
<Salary>77777</Salary>
<section>ssss</section>
</RECORD>
</EMPLOYEE>

This is a 50 GB file I want to read this file in multithreading mode and write to a multiple files(one for each thread) with the Salary and section (salary~section) . Trying to do it in C++

After that i will have to merge this file, i am pretty new to threading concepts in C++. Can any one please suggest me a way in doing this

Thanks
Arun

NAME
CGI::XML - Perl extension for converting CGI.pm variables to/from XML SYNOPSIS
use CGI::XML; $q = new CGI::XML; # convert CGI.pm variables to XML $xml = $q->toXML; $xml = $q->toXML($root); # convert XML to CGI.pm variables $q->toCGI($xml); DESCRIPTION
The CGI::XML module converts CGI.pm variables to XML and vice versa. CGI::XML is a subclass of CGI.pm, so it reads the CGI variables just as CGI.pm would. METHODS
$q = new CGI::XML creates a new instance of CGI::XML. You also have access to all of the methods in CGI.pm. $q->toXML([$root]) where $root is an optional parameter that specifies the root element. By default, toXML will not return a root element. $q->toCGI($xml) where $xml is the XML you would like to convert to CGI.pm parameters. Values in the XML will overwrite any existing values if they exist. NOTE
CGI::XML does not currently handle multiple selections passed from HTML forms. This will be added in a future release. AUTHOR
