Please use code tags! (The co/de symbol at the top of the Wiki editor)
awk splits the input lines into fields $1 $2 ... $NF.
NF is number of fields, NR the line number.
Code:
awk -F "|" '{ print $26 } (NR==10) { exit }' filename'

You can add an egrep-like condition
Code:
awk -F "|" '($26 ~ /eregex/){ print $26 } (NR == 10) { exit }' filename'

And/or modify your output e.g. { print $0 } that is the whole line.

GAPPLETVIEWER(1)                                                        GNU                                                       GAPPLETVIEWER(1)

NAME

       gappletviewer - Load and runs an applet

SYNOPSIS

       appletviewer [OPTION]... URL...

       appletviewer [OPTION]... -code CODE

       appletviewer [OPTION]... -plugin INPUT,OUTPUT

DESCRIPTION

       The appletviewer tool loads and runs an applet.

       Use the first form to test applets specified by tag.  The URL should resolve to an HTML document from which the appletviewer will extract
       applet tags.  The APPLET, EMBED and OBJECT tags are supported.  If a given document contains multiple applet tags, all the applets will be
       loaded, with each applet appearing in its own window.  Likewise, when multiple URLs are specified, each applet tag instance is given its
       own window.  If a given document contains no recognized tags the appletviewer does nothing.

               appletviewer http://www.gnu.org/software/classpath/

       Use the second form to test an applet in development.  This form allows applet tag attributes to be supplied on the command line.  Only one
       applet may be specified using the -code option.  The -code option overrides the URL form -- any URLs specified will be ignored.

               appletviewer -code Test.class -param datafile,data.txt

       gcjwebplugin uses the third form to communicate with the appletviewer through named pipes.

       PLUGIN OPTION

           gcjwebplugin uses the -plugin option to specify the named pipe the appletviewer should use for receiving commands (INPUT) and the one
           it should use for sending commands to gcjwebplugin (OUTPUT).

       DEBUGGING OPTION

       -JOPTION

           space between the -J and OPTION.
