正则表达式替换字符串（smarty）

Question

我正在尝试用空 space("") 替换特定字符（冒号）后的字符串 ":"

示例：2017 - Alpha Romeo United kingdom : New vehicle (by abc)

我想输出为“2017 - Alpha Romeo United kingdom”

如果有人能帮我用 smarty 写正则表达式，我将不胜感激

非常感谢

Answer 1

您可以使用以下 regex （使用 capturing group and positive lookahead） :

input        >>  2017 - Alpha Romeo United kingdom : New vehicle (by abc)
regex search >>  (?=:):(.*)
replace with >>  " "
output       >>  2017 - Alpha Romeo United kingdom

见demo / explanation

{
    assign
    var = "articleTitle"
    value = "2017 - Alpha Romeo United kingdom : New vehicle (by abc)"
} {
    $articleTitle | regex_replace: "/(?=:):(.*)/": " "
}

Answer 2

     private void Form1_Load(object sender, EventArgs e)
    {
        string str = "2017 - Alpha Romeo United kingdom : New vehicle (by abc)";
        str = Regex.Replace(str, @":+(.*)", "");
        MessageBox.Show(str);

    }
