我正在尝试匹配多行字符串，但无法正常工作

Question

我不会删除它，

我尝试了这个How do I match any character across multiple lines in a regular expression?。但没有用。

<span> powered by </span>
<a
 href="http://keystonejs.com"
 target="_blank"
 className={css(classes.link)}
 tabIndex="-1"
>
 KeystoneJS
</a>

const string = `
        tabIndex="-1"
                        className={css(classes.link)}
                    >
                        {brand + (appversion ? (' ' + appversion) : '')}
                    </a>
                    <span> powered by </span>
                    <a
                        href="http://keystonejs.com"
                        target="_blank"
                        className={css(classes.link)}
                        tabIndex="-1"
                    >
                        KeystoneJS
                    </a>
                    <span> version {version}.</span>
                    {this.renderUser()}
`;

console.log(string.match(/<span>\spowered(.*)<\/a>/gmi));

Answer 1

这有效

string.match(/<span>\spowered(.|\n)*<\/a>/gim)

您的代码无效，因为。与新行不匹配
