WHAT "is not working"? Any error messages?


If it's about awk not being happy with the field separator try escaping the square brackets:
Code:
dlm="<SelectStatement modified='1' type='string'><\!\\[CDATA\\["
awk -F"$dlm" '{print $2}' file
 SELECT

ud.conf

UD.CONF(5)							File Formats Manual							UD.CONF(5)

NAME

       ud.conf - ud configuration file

SYNOPSIS

       /etc/openldap/ud.conf

DESCRIPTION

       The  ud	configuration file is used to set system-wide defaults to be applied when running ud.  Note that each user may specify an optional
       configuration file, .udrc, in his/her home directory which will be used instead of the system-wide configuration file.

OPTIONS

       The different configuration options are:

       HOST <name>
		 Used to specify the name of an LDAP server to which ud should connect.  There may  be	only  one  entry  per  config  file.   The
		 server's name can be specified as a domain-style name or an IP address.

       BASE <base>
		 Used to specify the search base to use when performing search operations.  The base may be changed by those using ud by using the
		 cb command.  There may be only one entry per config file.  The base must be specified as a Distinguished Name in LDAP format.

       GROUPBASE <base>
		 Used to specify the base used when creating groups.  The base may be changed by those using ud by using the changegroup  command.
		 There may be only one entry per config file.  The base must be specified as a Distinguished Name in LDAP format.

       SEARCH <algorithm>
		 Used  to specify a search algorithm to use when performing searches.  More than one algorithm may be specified, and each is tried
		 in turn until a suitable response is found.

		 Each algorithm specifies a filter that should be used when performing a find operation.   Filters  contain  LDAP-style  attribute
		 types	(e.g.,	uid,  cn, postalAddress) and operators to test for equality or approximate equality.  Prefix operators may also be
		 used to specify AND, OR and NOT operations (see ldap(3) for more details on the filter format).  Algorithms  use  a  compile-time
		 constant  as a separator to use when parsing the input the user has provided.	This parsed input can then be referenced similarly
		 to an awk program using symbols like $1, $2, and $0 for the entire batch of input.

		 For example, the algoritm cn=$0 causes ud to perform a lookup on the entire string the user has  typed,  searching  for  anything
		 where the commonName exactly matches the whole thing.

		 Another  example, sn~=$NF causes ud to do a search where the last element the user has typed (NF = number of fields and is a spe-
		 cial "number" that can be used in awk as well as ud) searching for any matches that approximately match Surname.

		 Search algorithms also support a special feature which allows one to specify the exact number of fields that must be  present	in
		 order for the algorithm to be applied.  This number must be specified between square brackets.

		 For  example,	[1]  uid=$1  causes  this  algorithm to be applied when the number of fields is exactly equal to one.  If there is
		 exactly one field, the token is looked up as a UID.
