it worked, but there is one more requirement,

thanks gowtham

Code:
sed -i "s/s_virtual_hostname\">lnxdb-pts-[0-9]*/&-vip/"  <filename>

so, from the above command, i Understood that you are searching this particular line in the file using sed

Code:
<host oa_var="s_virtual_hostname">lnxdb-pts-454</host>

so does * indicate the later part of the line which means "</host> ?
and
in the second argument of sed how does "&" going to work?

========== My second Requirement is =========

Code:
<dbsharedpool oa_var="s_dbsharedpool_size">300000000</dbsharedpool>
         <dbutilfiledir oa_var="s_db_util_filedir" osd="unix">/apps/orarpt/TS3CTS/utl</dbutilfiledir>

******Output should be as follows******

the New line should be added from outside ("NOROLLBACK" line) and should exactly come in the middle of the above two lines........
Code:
<dbsharedpool oa_var="s_dbsharedpool_size">300000000</dbsharedpool>
         <dbrollbacksegs oa_var="s_db_rollback_segs">NOROLLBACK</dbrollbacksegs>
         <dbutilfiledir oa_var="s_db_util_filedir" osd="unix">/apps/orarpt/TS3CTS/utl</dbutilfiledir>


Thank you once again,
Kindly Address my queries

NAME
iptables-xml -- Convert iptables-save format to XML SYNOPSIS
iptables-xml [-c] [-v] DESCRIPTION
iptables-xml is used to convert the output of iptables-save into an easily manipulatable XML format to STDOUT. Use I/O-redirection pro- vided by your shell to write to a file. -c, --combine combine consecutive rules with the same matches but different targets. iptables does not currently support more than one target per match, so this simulates that by collecting the targets from consecutive iptables rules into one action tag, but only when the rule matches are identical. Terminating actions like RETURN, DROP, ACCEPT and QUEUE are not combined with subsequent targets. -v, --verbose Output xml comments containing the iptables line from which the XML is derived iptables-xml does a mechanistic conversion to a very expressive xml format; the only semantic considerations are for -g and -j targets in order to discriminate between <call> <goto> and <nane-of-target> as it helps xml processing scripts if they can tell the difference between a target like SNAT and another chain. Some sample output is: <iptables-rules> <table name="mangle"> <chain name="PREROUTING" policy="ACCEPT" packet-count="63436" byte-count="7137573"> <rule> <conditions> <match> <p>tcp</p> </match> <tcp> <sport>8443</sport> </tcp> </conditions> <actions> <call> <check_ip/> </call> <ACCEPT/> </actions> </rule> </chain> </table> </iptables-rules> Conversion from XML to iptables-save format may be done using the iptables.xslt script and xsltproc, or a custom program using libxsltproc or similar; in this fashion: xsltproc iptables.xslt my-iptables.xml | iptables-restore BUGS
