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

cgi::xml
XML(3pm) User Contributed Perl Documentation XML(3pm)
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.
