我大约有1000行数据，C列中的每个单元格都填充了博客文章的html。我需要提取任何以“ https：//”开头并以“ .jpg”结尾的URL（文本字符串）
每个单元格中每个URL多次出现，并且某些单元格中也包含其他URL（没有超链接，都是纯文本）
我尝试了很多FIND，IF，MID等...，但仅在一次出现时有效。
有人可以帮助宏吗？谢谢！

在D1（或适合您的任何其他列）中输入以下公式：
<?php //Linking the configuration file
require '../config.php';
session_start();
if(isset($_POST["btnSubmit"])){
$firstname = $_POST["fname"];
$lastname = $_POST["lname"];
$email = $_POST["email"];
$address = $_POST["address"];
$state = $_POST["state"];
$zip = $_POST["zip"];
$username = $_POST["username"];
$password = md5($_POST['password']);
$sql= "INSERT INTO signup
(user_id, fname, lname, email , address ,
country , postal_code , username, password )
VALUES (NULL,' firstname', '$lastname', '$email', '$address',
'$state', '$zip', '$username','$password')";
if(mysqli_query($conn,$sql)){
//echo "Inserted successfully";
header('http://localhost:8080/project/FINAL%20PAGE/register/myaccount.php');
} else{
echo "Error:". $conn->error;
}
}
?>

答案 1 :(得分：0)
我最终只是通过简单的查找和替换操作来完成此操作。起初我以为每个URL都太不同了，但是唯一的区别是每个URL末尾有2个文件夹（路径），例如：2017/01 / filename.jpg。因此，在此之前，我只是在根url上进行了查找和替换，然后转到新的url路径，然后在每个月的文件夹中进行了查找和替换，以将其删除。它只能追溯到2010年左右。
出于记录目的，只是为了不必要地为自己辩护，最初的问题是：“每个单元格中都有多个重复出现的原因，这就是为什么我可以确定我需要一个宏，但很显然，通常，这是一种更简单的方法！
