Linux shell script loop to process files in a directory

To process .txt files in a directory, but skipping the first few and the last few -

count=0

ls | grep -E "\.txt" | while read line; do

    count=`expr $count + 1`

    if [ $count -le 10 ] ; then

        continue

    fi

    echo $line

    if [ $line = "xyz.txt" ]; then

        break

    fi

done
