below is the output xml string from some other command and i will be parsing it using awk
cat /tmp/alerts.xml
<Alert id="10102" name="APP-DS-ds_ha-140018-componentFailure-S" alertDefinitionId="13982" resourceId="11427" ctime="1359453507621" fixed="false" reason="If Event/Log Level(ANY) and matching substring "failed on server" Log: 10.19.123.197: 0:25:48.04, 1.3.6.1.4.1.1453.4.9.1.3.0.1, The service has failed on this server and caused an HA failover to occur., CLR OCCAS failed on server 10.19.123.197, failure, 2013-01-29,04:58:27.6,--5:0, CLEAR, 10.19.123.197, failure, 2013-01-29,04:58:27.6,--5:0, CLEAR, The service has"/>
.

.
etc ect
which i will be parsing using below command
awk -F'[=|"|<|>|,]' '{for(i=1;i<=NF;i++){
if($i=="Alert id") {
if(id!="")
if(dt!=""){ printf "ID=%d\nNAME=%s\nFIXED=%s\nDATE=%s\nAlDefID=%d\n\n", id,nm,fx,dt,alDFid; }
id=($i=="Alert id")?$(i+2):id; }
nm=($i==" name")?$(i+2):nm;
fx=($i==" fixed")?$(i+2):fx;
dt=($i~/^ [0-9]+-/)?$i" "$(i+1):dt;
alDFid=($i==" alertDefinitionId")?$(i+2):alDFid;
}
}END{
if(dt!=""){
printf "ID=%d\nNAME=%s\nFIXED=%s\nDATE=%s\nAlDefID=%d\n\n", id,nm,fx,dt,alDFid;
}
}' /tmp/alerts.xml
output will be as below
ID=10102
NAME=APP-DS-ds_ha-140018-componentFailure-S
FIXED=false
DATE= 2013-01-29 04:58:27.6
AlDefID=13982
.
.
.etc etc many entries will be there
what i want to achieve is
>in the awk command i want to implement a check for date, first i will parse the date obtained from the query to only date and no time stamp and also system date
myDate=$( date --date="$DATE" +%Y%m%d )
sysDate=$( date +%Y%m%d )
and if this date is older than system date then dont print from awk
if [[ $myDate -eq $sysDate ]] ;then
print
else
skip all
fi
>also i need to perform one more operation
sh /opt/hqe/hqapi1-client-5.0.0/bin/hqapi.sh alertdefinition list --id=13982 --host=localhost --port=7443 --user=hqadmin --password=hqadmin --secure=true | grep priority | awk -F'priority=' '{print $2}' | cut -d'"' -f2
whose output will be
3
PS: i am not good at parsing xml so i did some my own awk and cut to get priority value from xml 
the above output is nothing but the priority obtained from that id and display it on console immediately.
--------------
so final output will be
ID=10102
NAME=APP-DS-ds_ha-140018-componentFailure-S
FIXED=false
DATE= 2013-01-29 04:58:27.6
AlDefID=13982
priority=3.
.
.etc etc many entries will be there
what i want to do is, use this hqapi.sh command inside mail xml parsing AWK command for each iteration and print priority then and there,
i tried using the hqapi command in quotes `` inside awk but it dint work.
any help on this will be deeply appreciated. thanks
PS:also if i succeed in all the above, is there any way i could use echo commands in awk so that i can put check in awk for printing priority in words say 1-lOW,2-MED,3HIGH in colour code using
echo -e "\e[1;31mHIGH\e[0m"
so the output
priority=HIGH

so far i implemented below stuff...
sh /opt/hqe/hqapi1-client-5.0.0/bin/hqapi.sh alert list --host=localhost --port=7443 --user=hqadmin --password=hqadmin --secure=true >/tmp/alerts.xml
awk -F'[=|"|<|>|,]' '{for(i=1;i<=NF;i++){
if($i=="Alert id") {
if(id!="")
if(dt!=""){
cmd="date +%Y%m%d"
cmd | getline sysDate
print sysDate
close(cmd)
cmd2="date --date=dt +%Y%m%d"
cmd2 | getline myDate
print myDate
close(cmd2)
cmd3="sh /opt/hqe/hqapi1-client-5.0.0/bin/hqapi.sh alertdefinition list --id=13671 --host=localhost --port=7443 --user=hqadmin --password=hqadmin --secure=true | grep priority | awk -F'priority=' '{print $2}' | cut -d'"' -f2 "
cmd3 | getline priority
print priority
close(cmd3)
printf "ID=%d\nNAME=%s\nFIXED=%s\nDATE=%s\nAlDefID=%d\n\n", id,nm,fx,dt,alDFid; }
id=($i=="Alert id")?$(i+2):id; }
nm=($i==" name")?$(i+2):nm;
fx=($i==" fixed")?$(i+2):fx;
dt=($i~/^ [0-9]+-/)?$i" "$(i+1):dt;
alDFid=($i==" alertDefinitionId")?$(i+2):alDFid;
}
}END{
if(dt!=""){
printf "ID=%d\nNAME=%s\nFIXED=%s\nDATE=%s\nAlDefID=%d\n\n", id,nm,fx,dt,alDFid;
}
}' /tmp/alerts.xml
Additions are :
cmd="date +%Y%m%d"
cmd | getline sysDate
print sysDate
close(cmd)
cmd2="date --date=dt +%Y%m%d"
cmd2 | getline myDate
print myDate
close(cmd2)
cmd3="sh /opt/hqe/hqapi1-client-5.0.0/bin/hqapi.sh alertdefinition list --id=13671 --host=localhost --port=7443 --user=hqadmin --password=hqadmin --secure=true | grep priority | awk -F'priority=' '{print $2}' | cut -d'"' -f2 "
cmd3 | getline priority
print priority
close(cmd3)
stuck at the place where i need to parse date present in 'dt' variable.. its not considering dt even if i put $ behind it. its throwin error as
date: invalid date `dt'
and for running the script , the cmd3 is not able to process it, its showing as
awk: cmd. line:14: cmd3="sh /opt/hqe/hqapi1-client-5.0.0/bin/hqapi.sh alertdefinition list --id=13671 --host=localhost --port=7443 --user=hqadmin --password=hqadmin --secure=true | grep priority | awk -Fpriority= {print
awk: cmd. line:14: ^ unterminated string
Can anyone help me to proceed further!!!!.. i see no one has replied to this.. the awk command looks complex but its actually simple...
dint help.
