MySQL Search & replace fields from file1 to file2
hi,

I have two xml files with the name source.xml and tobe_replaced.xml.

Sample data:
source.xml contains:
Code:
<?xml version="1.0"?>
<product description="prod1" product_info="some/info">
<product description="prod2" product_info="xyz/allinfo">
<product description="abc/partialinfo" product_info="abc/partialinfo/edited">
..

tobe_replaced.xml contains:
Code:
<?xml version="1.0"?>
<product description="prod1" product_info="pqr/msg1">
<product description="prod2" product_info="zab/allmsg">
<product description="abc/partialinfo" product_info="abc/partialinfo/unchanged">
..

i want to search description and take the value after =" ie prod1,prod2,abc/partialinfo and also get the product_info values ie some/info,abc/partialinfo/edited .
this is done as follows or similar to this:

Code:
awk -F\" '/description/ { print $2 $4}' source.xml

In tobe_replaced.xml, search the value of $2 and replace product_info with value of $4 for all the lines from source.xml to tobe_replaced.xml.

desired output in tobe_replaced.xml is:
Code:
<?xml version="1.0"?>
<product description="prod1" product_info="some/info">
<product description="prod2" product_info="xyz/allinfo">
<product description="abc/partialinfo" product_info="abc/partialinfo/edited">
..

How do i do this while reading all the lines from both the files?

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.
