Here's one way to do it:

Code:
$
$ cat -n datafile
     1  AAA
     2  BBB
     3  CCC
     4  1
     5  2
     6  3
     7  xYz
     8
     9  456
    10  abc12de
    11  xyz~!lm.&
$
$
$ cat testarray.pl
#!perl -w
open(FILE, "<datafile");
while (<FILE>) {
  chomp;
  if ($_ =~ /^[[:alpha:]]+$/) {
    push @stringArray, $_;
  } elsif ($_ =~ /^\d+$/) {
    push @intArray, $_;
  }
}
close(FILE);
print("\nString Array ===> @stringArray");
print("\nInt Array    ===> @intArray");
print("\n");
$
$
$ perl testarray.pl
String Array ===> AAA BBB CCC xYz
Int Array    ===> 1 2 3 456
$
$

Note:
- Due to the "+" quantifier, the regexes look for at least one character/digit. Hence line no. 8 was left out.
- The match is case-insensitive e.g. line no. 7
- The [:alpha:] POSIX character class does not match alphanumeric and special characters due to which lines 10 and 11 were left out.

Hope that helps,

XcmsCCCOfColormap(3X11) 					  XLIB FUNCTIONS					   XcmsCCCOfColormap(3X11)

NAME

       XcmsCCCOfColormap, XcmsSetCCCOfColormap - query and modify CCC of a colormap

SYNTAX

       XcmsCCC XcmsCCCOfColormap(display, colormap)
	     Display *display;
	     Colormap colormap;

       XcmsCCC XcmsSetCCCOfColormap(display, colormap, ccc)
	     Display *display;
	     Colormap colormap;
	     XcmsCCC ccc;

ARGUMENTS

       display	 Specifies the connection to the X server.

       ccc	 Specifies the CCC.

       colormap  Specifies the colormap.

DESCRIPTION

       The XcmsCCCOfColormap function returns the CCC associated with the specified colormap.  Once obtained, the CCC attributes can be queried or
       modified.  Unless the CCC associated with the specified colormap is changed with XcmsSetCCCOfColormap, this CCC is used when the specified
       colormap is used as an argument to color functions.

       The XcmsSetCCCOfColormap function changes the CCC associated with the specified colormap.  It returns the CCC previously associated with
       the colormap.  If they are not used again in the application, CCCs should be freed by calling XcmsFreeCCC.  Several colormaps may share the
       same CCC without restriction; this includes the CCCs generated by Xlib with each colormap.  Xlib, however, creates a new CCC with each new
       colormap.
