Avoid Duplicates in a file
Hi Gurus,

I had a question regarding avoiding duplicates.i have a file abc.txt
abc.txt
-------
READER_1_1_1> HIER_28056 XML Reader: Error [UnterminatedXMLDecl] occurred while parsing:[Error at (file /home/abc.xml, line 6, char 1 ): Invalid document structure.]; line number [6]; column number [1]

READER_1_3_1> Sun Mar 23 23:52:48 2008
READER_1_3_1> HIER_28058 XML Reader Error.


I will get this file when i egrep the session log file for error specific messages.

here i want to remove the repeated lines in this file?
i am try to use uniq command, but here READER_1_3_1> will be varying in the above abc.txt file
i.e., in every line we have 1,2,3 in place of READER_1_**_1>.

So i am not getting the desired output.

Can any one let me know how to get the requirement done.

My output should be
READER_1_1_1> HIER_28056 XML Reader: Error [UnterminatedXMLDecl] occurred while parsing:[Error at (file /home/abc.xml, line 6, char 1 ): Invalid document structure.]; line number [6]; column number [1]
READER_1_1_1> HIER_28058 XML Reader Error

Smilie

Thanks & Regards,
San

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.
