Here I got some "quick fixes" to two of your problems:

Prob1:
++++++
$ cat source1.xml
<ext:ContactInfo xmlns:ext="urn:AOL.FLOWS.Extensions">
<ext:InternetEmailAddress>AOL@AOL.COM</ext:InternetEmailAddress>
</ext:ContactInfo>

$ cat source1.xml | sed '/ext:ContactInfo/d'
<ext:InternetEmailAddress>AOL@AOL.COM</ext:InternetEmailAddress>

Prob3:
+++++++
$ cat source3.xml
<IFeed>
<Organization>
<Participant>.
<ParticipantName>..</ParticipantName>
<ParticipantId>.</ParticipantId>
</ Participant>
</ Organization>
</IndicFeed>
<IFeed>
<Organization>
<Participant>.
<ParticipantName>..</ParticipantName>
<ParticipantId>.</ParticipantId>
</ Participant>
</ Organization>
</IFeed>


The idea is to remove the all "Organization" tags except the 1st and last one. Similarly the "IFeed". Here we go

----
#!/bin/sh

#this function will remove all instances of any tag (except 1st and last)
f_remove() {
count=0
RMVPARAM=$1
grep -n "$RMVPARAM>" source3.xml | awk -F ":" '{print $1}'| sed -e '1d' -e '$d' | while read lnum
do
num=`expr $lnum - $count`
echo $num
sed "$num d" source3.xml > source3.xml.tmp
mv source3.xml.tmp source3.xml
count=`expr $count + 1`
done
}

f_remove Organization
f_remove IFeed
---

Now

$ cat source3.xml
<IFeed>
<Organization>
<Participant>.
<ParticipantName>..</ParticipantName>
<ParticipantId>.</ParticipantId>
</ Participant>
</IndicFeed>
<Participant>.
<ParticipantName>..</ParticipantName>
<ParticipantId>.</ParticipantId>
</ Participant>
</ Organization>
</IFeed>

%%</IndicFeed> can be removed directly, if not required :-)

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
