#!/bin/bash

main(){
  num=1
  echo "<?xml version="1.0" encoding="utf-8"?>
<direct>
</direct>
" > direct.xml
#  read -p "请输入文件全路径名称：" ip_addr
  while read line
  do 
    policy="<rule priority=$num table="filter" ipv="ipv4" chain="OUTPUT">-d $line -j ACCEPT</rule>"
    echo $policy
    sed -i "/<\/direct>/i ${policy}" direct.xml
    num=$(( $num + 1 ))
  done < $1
