You could read it into a variable, then parse it. Depending on amount of data
this works:

You have a file with:
url1
file1
url2
file2
url3
file3
url4
file4

The script:

#!/bin/sh
#
Data=`cat datalist`
Count=1
echo "" > sortedlist
for URL in $Data ; do
        if [ "$Count" -eq "1" ] ;then
                Line="$URL"
        else
                echo "$Line $URL"
                echo "$Line $URL" >> sortedlist
                Line=""
                Count=0
        fi
        Count=$(($Count+1))
done
echo
echo "Result file:"
cat sortedlist

The sortedlist:
url1 file1
url2 file2
url3 file3
url4 file4
