Help required in Building an XML using SAX Parser in perl
I want to use sax parser for my application as i have 5 Lakhs of data.

I have the xml file like this
Code:
<Nodes>
	<Node>
	 <NodeName>Company</NodeName>
     <File>employee_details.csv</File>
     <data>employee_data.txt</data>
	 <Node>
	 <NodeName>dummy</NodeName>
     <File>employee_details1.csv</File>
     <data>employee_data1.txt</data>
	</Node>
	</Node>
</Nodes>
#Contents of employee_data.txt
Empname,Empcode,EmpSal:Currency,Empaddr
#Contents of employee_details.csv (like this huge data)
Alex,A001,1000:USD,Bangalore
Aparna,B001,1000:RUBEL,Bombay
#Contents of employee_data1.txt
phone,fax
#Contents of employee_details1.csv (like this huge data)
44568889,123345656
23232323,454545757

I have to process these and print it in the xml format. I want to use SAX Parser.

Output:
Code:
<Company>
<Empname>Alex</Empname>
<Empcode>A001</Empcode>
<EmpSal=USD>1000</EmpSal>
<Empaddr>Bangalore</Empaddr>
<phone>44568889</phone>
<fax>123345656</fax>
</Company>
<Company>
<Empname>Aparna</Empname>
<Empcode>B001</Empcode>
<EmpSal=RUBEL>1000</EmpSal>
<Empaddr>Bombay</Empaddr>
<phone>23232323</phone>
<fax>454545757</fax>
</Company>

I am very new to perl parser so finding it difficulty in building an xml tree.

Since there is huge amount of data parsing and putting the parsed content will be better using an Sax parser as read by posts.

How can i get the above output using an SAX parser?

Help is very much required.

Regards
Vanitham

xml::sax::expat

Expat(3pm)						User Contributed Perl Documentation						Expat(3pm)

NAME

       XML::SAX::Expat - SAX2 Driver for Expat (XML::Parser)

SYNOPSIS

	 use XML::SAX::Expat;
	 use XML::SAX::MyFooHandler;
	 my $h = XML::SAX::MyFooHandler->new;
	 my $p = XML::SAX::Expat->new(Handler => $h);
	 $p->parse_file('/path/to/foo.xml');

DESCRIPTION

       This is an implementation of a SAX2 driver sitting on top of Expat (XML::Parser) which Ken MacLeod posted to perl-xml and which I have
       updated.

       It is still incomplete, though most of the basic SAX2 events should be available. The SAX2 spec is currently available from
       http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/~checkout~/perl-xml/libxml-perl/doc/sax-2.0.html?rev=HEAD&content-type=text/html

       A more friendly URL as well as a PODification of the spec are in the works.

METHODS

       The methods defined in this class correspond to those listed in the PerlSAX2 specification, available above.

FEATURES AND CAVEATS

       supported_features
	 Returns:

	   * http://xml.org/sax/features/external-general-entities
	   * http://xml.org/sax/features/external-parameter-entities
	   * [ Features supported by ancestors ]

	 Turning one of the first two on also turns the other on (this maps to the XML::Parser ParseParamEnts option). This may be fixed in the
	 future, so don't rely on this behaviour.

MISSING PARTS

       XML::Parser has no listed callbacks for the following events, which are therefore not presently generated (ways may be found in the
       future):

	 * ignorable_whitespace
	 * skipped_entity
	 * start_entity / end_entity
	 * resolve_entity

       Ways of signalling them are welcome. In addition to those, set_document_locator is not yet called.

TODO

	 - reuse Ken's tests and add more
