Replace a string for every record after the 1st record
I have data coming in the below format for each record

Code:
<?xml version="1.0" encoding="UTF-8" standalone="no"?><test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><testdetials>....</test_sox>
<?xml version="1.0" encoding="UTF-8" standalone="no"?><test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><testdetials>....</test_sox>

I need to remove the the XML prolog on the 2nd record until the last record
Code:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>


The o/p should look like below
Code:
<?xml version="1.0" encoding="UTF-8" standalone="no"?><test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><testdetials>....</test_sox>
<test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><testdetials>....</test_sox>

I might have more than 100 records and this should happen to all the records starting from 2nd record.

Hello dsravanam,

Could you please use code tags in spite of using quotes for commands/Inputs/codes into your posts as per forum rules. Because of not using code tags your Input_file didn't come properly so let's say you have following Input_file:
Code:
cat Input_file
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-ins.......</test_sox>
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-ins.......</test_sox>

Now following is the code which may help you in same.
Code:
awk 'NR==1{print;next} !/<\?xml version=\"1\.0\" encoding=\"UTF-8\" standalone=\"no\"\?>/{print}'   Input_file

Output will be as follows.
Code:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-ins.......</test_sox>
<test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-ins.......</test_sox>

on a Solaris/SunOS system, change awkto /usr/xpg4/bin/awk , /usr/xpg6/bin/awk , or nawk. Also if you have a different requirement then request you to please show us sample input with expected sample output, with your O.S details to us to help you.

Thanks,
R. Singh

How about
Code:
awk 'NR>1 {sub (/^<[^>]*>/, "")} 1' file
<?xml version="1.0" encoding="UTF-8" standalone="no"?><test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><testdetials>....</test_sox>
<test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><testdetials>....</test_sox>

You may want to refine the regex for the sub function to be more specific if need be.

Thanks Rudic. If i have to replace the below string at the end of each record except the last record what should i use

PHP Code:
</test_sox>

Old 02-10-2016
Are you sure? That would result in invalid xml elements <test_sox ...> as they all wouldn't be closed.

Rudic

I am sorry for the confusion. Actually I need from the 2nd record onwards to remove the below string as well

Code:
<test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Code:
<?xml version="1.0" encoding="UTF-8" standalone="no"?><test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><testdetials>....</test_sox>
<test_sox xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><testdetials>....</test_sox>
