Hi gigamesh,
The following should work with either nawk or /usr/xpg4/bin/awk on Solaris 10:
Code:
#!/bin/bash
CURR_DATE=$(TZ=GMT48 date '+%Y-%m-%d')
echo $CURR_DATE
/usr/xpg4/bin/awk -v var="$CURR_DATE" '
/<run>/ {
	found = 0
	record = $0
	next
}
{	record = record "\n" $0
}
$0 ~ var {
	found = 1
}
/<\/run>/ && found {
	print record
}' file.XML

Note that I used TZ=GMT48 because your sample data only contains July 3rd datestamps and it is no longer July 4th in Greenwich in GMT and I used a hard-coded pathname for your sample data file (where I placed it on my system) because your sample code didn't initialize the XML_FILE variable.

I don't see any reason why the awk code MadeInGermany suggested should not work (assuming that you defined CURR_DATE and XML_FILE appropriately when you tried running it). In what way did it fail?

Hi MadeInGermany,
The awk in /bin or /usr/bin on Solaris 10 systems is the original awk produced by Aho, Weinberg, and Kernighan in the 1970's. There are still some scripts laying around that depend on that version of awk.

Cheers,
Don

ucblinks(1B)					     SunOS/BSD Compatibility Package Commands					      ucblinks(1B)

NAME
       ucblinks - adds /dev entries to give SunOS 4.x compatible names to SunOS 5.x devices

SYNOPSIS
       /usr/ucb/ucblinks [-e rulebase] [-r rootdir]

DESCRIPTION
       ucblinks  creates symbolic links under the /dev directory for devices whose SunOS 5.x names differ from their SunOS 4.x names. Where possi-
       ble, these symbolic links point to the device's SunOS 5.x name rather than to the actual /devices entry.

       ucblinks does not remove unneeded compatibility links; these must be removed by hand.

       ucblinks should be called each time the system is reconfiguration-booted, after any new SunOS 5.x links that are needed have been  created,
       since the reconfiguration may have resulted in more compatibility names being needed.

       In  releases prior to SunOS 5.4, ucblinks used a  nawk rule-base to construct the SunOS 4.x compatible names. ucblinks no longer uses  nawk
       for the default operation, although  nawk rule-bases can still be specifed with the -e option.  The  nawk rule-base equivalent to the SunOS
       5.4 default operation can be found in /usr/ucblib/ucblinks.awk.

OPTIONS
       -e rulebase     Specify rulebase as the file containing nawk(1) pattern-action statements.

       -r rootdir      Specify rootdir as the directory under which dev and devices will be found, rather than the standard root directory /.

FILES
       /usr/ucblib/ucblinks.awk        sample rule-base for compatibility links
