how to replace html line into a command line?

hi!

i'm trying to use sed for this, but i'm struggling a lot. i want to convert

Code:
<div class="middle" id="middle">Friday, 20 April 2012<br /> <span class="hex">728CB5</span> <br /></div>

into

Code:
fbsetroot -solid '#728CB5'

considering all information between 'id="middle">' and '<br /> <span' should be ignored or removed earlier (because it may vary), or only considering the information between '="hex">' and '</span>'

(that html line above were obtained from
Code:
wget http://www.chromatweet.com/index.html -O _.html && cat _.html | grep hex | grep middle

) (added some spaces on the url above because this forum is blocking urls in messages like this)

thanks in advance! Smilie

this code is working, but if you know some way to make it simpler, be welcome suggesting
Code:
wget http://www.chromatweet.com/index.html -O _.html
cat _.html | grep hex | grep middle | sed -n -e 's/.*hex\"\(.*\)\/span.*/\1/p' | sed -e 's/>/fbsetroot -solid \x27#/' | sed -e 's/</\x27/' > _.sh
chmod +x _.sh && bash _.sh && rm _.sh _.html

Hi nitrofurano,

One way with perl:
Code:
$ perl -MLWP::Simple -e '
    if ( ( grep { m/middle/ && m/hex/ } split /\n/, get( q[http://www.chromatweet.com/index.html] ) )[0] =~ m/"hex">(\d+)</ ) { 
        system( q[fbsetroot], q[-solid], qq['#$1'] ) 
    }
'
