Data search and replace symlinks

Hello All,

Assuming i have a thousand symlinks under directory /mydir (and its sub-dir) such as:

mysymlink1 -> ../../../myfoo/mysymlink1
mysymlink2 -> ../../../myfoo/mysymlink2

How can I search the string "myfoo" and replaced with "yourfoo" such that after the operation is complete the /mydir will look like this:

mysymlink1 -> ../../../yourfoo/mysymlink1
mysymlink2 -> ../../../yourfoo/mysymlink2

======
Thanks!

This is a little on the dangerous side to say the least. Run this script...it will produce a second script. Examine that second script carefully before you run it.
Code:
#! /usr/bin/ksh

function dodir
{
        typeset fname data savedir
        ls | while read fname ; do
                if [[ -L $fname ]] ; then
                        data=$(ls -l $fname)
                        data=${data##* }
                        data=$(echo "$data" | sed 's=myfoo=yourfoo=')
                        echo rm $1/$fname
                        echo ln -s $data $1/$fname
                elif [[ -d $fname ]] ; then
                        savedir=$(pwd)
                        cd $fname
                        dodir $savedir/$fname
                        cd $savedir
                fi
        done
        return
}

dodir $(pwd)
exit 0
