Question

我有这个字符串：

＆＃34; Lorem ipsum dolor sit amet，{{foo.name}} consectetuer adipiscing elit。 Aenean commodo ligula eget dolor。 {{bar.address}} Aenean massa。 Cum sociis natoque penatibus et magnis dis parturient montes，nascetur ridiculus mus。 Donec quam felis，ultricies nec，{{dummy.company}} pellentesque eu，pretium quis，sem。＆＃34;

我需要提取用双花括号括起来的字符串（foo.name，bar.address，dummy.company），它由2个由句点分隔的子字符串组成。我怎么能用正则表达式做到这一点？

仍然是正则表达式的初学者，并尝试了/ [az]。[ - z]，但没有得到正确的匹配。

使用regexp101.com：

$re = '/({{.*?}})/';
$str = 'Lorem ipsum dolor sit amet, {{foo.name}} consectetuer adipiscing elit.
Aenean commodo ligula eget dolor. {{bar.address}} Aenean massa. Cum sociis 
natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. 
Donec quam felis, ultricies nec, {{dummy.company}} pellentesque eu, pretium 
quis, sem.';

preg_match_all($re, $str, $matches, PREG_SET_ORDER, 0);

// Print the entire match result
var_dump($matches);

oops是php - JavaScript是：

const regex = /({{.*?}})/g;
const str = `Lorem ipsum dolor sit amet, {{foo.name}} consectetuer adipiscing elit. 
Aenean commodo ligula eget dolor. {{bar.address}} Aenean massa. Cum sociis 
natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. 
Donec quam felis, ultricies nec, {{dummy.company}} pellentesque eu, pretium 
quis, sem. `;
let m;

while ((m = regex.exec(str)) !== null) {
    // This is necessary to avoid infinite loops with zero-width matches
    if (m.index === regex.lastIndex) {
        regex.lastIndex++;
    }

    // The result can be accessed through the `m`-variable.
    m.forEach((match, groupIndex) => {
        console.log(`Found match, group ${groupIndex}: ${match}`);
    });
}

正则表达式 - 由花括号括起并以句点分隔的2个字符串的模式
