I believe it will help you to know that dig has a "short" mode:
Code:
dig +short txt google.com

produces:
Code:
"v=spf1 include:_netblocks.google.com ~all"

I don't know what your sed command really does, but you can combine it with the cut-quotes command:
Code:
sed 's/"//g; s/ip4://g;'

I'm not sure what the complaint about "recursion" is: If you encounter an "include", you need to "follow it", recursively:
Code:
get_dns_spf1() { 
   dig +short txt "$1" | 
   tr ' ' '\n' |
   while read entry; do 
      case "$entry" in 
         ip4:*)  echo ${entry#*:} ;; 
         include:*) get_dns_spf1 ${entry#*:} ;;
      esac
   done |
   sort -u
   ;
}

This outputs a list. To get the output of the list in an array, just do:
Code:
ips=(`get_dns_spf1 some.site.com`)

Now you can just
Code:
echo ${ips[*]}

GOOGLE-SITEMAPGEN(1)					      General Commands Manual					      GOOGLE-SITEMAPGEN(1)

NAME

       google-sitemapgen -- simple script to automate production of sitemaps for a webserver

SYNOPSIS

       google-sitemapgen [--testing]  [--help]	[--config=config.xml]

DESCRIPTION

       This manual page documents briefly the google-sitemapgen command.

       This manual page was written for the Debian distribution because the original program does not have a manual page.

       google-sitemapgen  is  a  program that automatically produces sitemaps for a webserver, in the Google Sitemap Protocol (GSP). Sitemap files
       are XML listings of content you make available on your web server. The files can be directly submitted to search engines as hints  for  the
       search  engine  web  crawlers as they index your web site. This can result in better coverage of your web content in search engine indices,
       and less of your bandwidth spent doing it.

OPTIONS

       --config=config.xml
		 Specify the location of the configuration config.xml

       --testing Used to test the sitemap generator configuration.

       --help	 Display a summary of options and exit.

SEE ALSO

       /usr/share/doc/google-sitemapgen/examples/example_config.xml.gz

       Google Sitemap was originally written by Google Code <opensource@google.com>.

       This manual page was written by Kumar Appaiah <akumar@ee.iitm.ac.in> for the Debian system (but may  be	used  by  others).  Permission	is
