Need help in using sed/awk for line insertion in xml

Hello,

I have two text files (txt1 and txt2). txt1 contains many lines with a single number in each line. txt2 (xml format) contains information about the numbers given in txt1. I need to insert one line in txt2 within the scope of each number taken from txt1.

Sample problem:
txt1:
12
23
45
67
78

txt2:
<id = "ab">
<>
<"add text here!!!">
</holder>
<>
<num = "12">
<>
<>
<>
<id = "bc">
<>
<"add text here!!!">
</holder>
<>
<num = "78">
<>
<>
<>
<id = "cd">
<>
<>
<>
<"dont add since 90 is not in the txt1">
</holder>
<num = "90">
<>
<>
hope i have not confused much..

so within the scope of each number place the text above the line </holder> for all the numbers present in txt1.

---------- Post updated at 04:11 PM ---------- Previous update was at 04:05 PM ----------

I have been able to insert the line above all the </holder> in the file... But I am stuck when I am matching the numbers from txt1 and inserting into txt2 into a specific location.....

here's the code I used to insert above all lines having </holder>

sed '/</\Holder>/i\<TEXT INSERTED>' filename

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
