awk print in script
Hi, Thanks to RudiC I have a functioning awk portion of a script which reads a text file and replaces all matching values in an XML.

I need help with placing print statements in the script to see line by line what is being replaced.

Script:
Code:
#!/bin/sh

if [ $# -eq 2 ]
  then
        echo
else
    echo "usage: $0 <Properties> <DeploymentXML>"
    exit
fi

TXT=$1
XML=$2

awk '
FNR == NR       {sub (/\./, "/", $TXT)
                 T[$TXT] = $XML
                 next
                }
                {for (t in T) if ($0 ~ t) TF = t
                }
TF && /<value/  {sub (/>[^<]*</, ">" T[TF] "<")
                 TF = ""
                }
TF && /<machine/{sub (/>[^<]*</, ">" T[TF] "<")
                 TF = ""
                }
1
' FS="~" $TXT $XML > temp &&  mv temp $XML

For example:
Text file contains multiple entries in the format of -


Code:
Application.Env~DEV 
Application.ID~99999

Pre-script XML contains multiple entries in the format of -

Code:
<name>Application/Env</name> 
<value>XXX</value> 
<name>Application/ID</name> 
<value>00000</value>

Post-script XML:

Code:
<name>Application/Env</name> 
<value>DEV</value> 
<name>Application/ID</name> 
<value>99999</value>

Thanks!

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.
