Here's a quick run down of what my small awk script does with each line of output from egrep:

awk -F">" '{print $2}'

splits

<photoshop:CaptionWriter>this is where the caption writer goes</photoshop:CaptionWriter>

into pieces using > as a field separator:

<photoshop:CaptionWriter
this is where the caption writer goes</photoshop:CaptionWriter

and grabs the second piece ($2), which is

this is where the caption writer goes</photoshop:CaptionWriter

Then the second awk command awk -F"<" '{print $1}' takes that line and splits it into pieces using < as a field separator:

this is where the caption writer goes
/photoshop:CaptionWriter

and grabs the first piece ($1), giving you:

this is where the caption writer goes

NAME

       surfraw-update-path - updates PATH in shell config files

SYNOPSIS

       surfraw-update-path [-add] [-remove] [-check] [-sys] [-all] [-help] [-shell=SHELL]

DESCRIPTION

       surfraw-update-path adds the surfraw elvi directory (/usr/lib/surfraw) to your PATH in your shell's config file.

       Currently it supports bash, sh, csh, tcsh, ash, dash, ksh, pdksh, zsh, rc, and es

       Don't forget to login again or source your login files for it to take effect.

OPTIONS

       -check
	   Checks to see if the surfraw config code is present.  This is the default.

       -add
	   Adds the surfraw config code.

       -remove
	   Removes the surfraw config code

       -sys
	   Updates the system-wide shell config instead of the user.  Must be done as root.

       -shell=SHELL
	   Selects the shell to configure. Defaults to the value of the $SHELL environment variable.

	   Currently supported shells are:

	   sh, ash, bash, dash, csh, tcsh, ksh, pdksh, zsh, rc, and es.

       -all
	   Attempts to configure the startup files for all known shells

       -help
	   Gives a usage message

RETURN VALUE

       -check returns 0 if the surfraw code is present in the file, 1 if it is not found, or 2 on error.

       All other options return 0 on success, or 2 on error.

ENVIRONMENT

       SHELL
	   Used to determine which shell to configure, if -shell is not given.

       HOME
	   Used to find users config files.

       ENV Used by posix-compliant shells to specify a startup rc file.

       ZDOTDIR
	   Used to find user config files for zsh. If not set, defaults to HOME.
