使用regex移动字符？

Question

如何使用正则表达式移动“颜色和大小”旁边的颜色和大小？这是我的正则表达式：https://regex101.com/r/fB3jK9/1

结果应该是这样：

我的样本输入如下：

Color and Size - Dark Blue|Small
    Dark Blue|Medium
    Dark Blue|Large
    Dark Blue|X-Large
Color and Size - Black|Small
    Black|Medium
    Black|Large
    Black|X-Large
    Ocean|Small
    Ocean|Medium
    Ocean|Large
    Ocean|X-Large
Color and Size - Black|Small
    Black|Medium
    Black|Large
    Black|X-Large
    Black|2X-Large
    Stone|Small
    Stone|Medium
    Stone|Large
    Stone|X-Large
    Stone|2X-Large

到目前为止，我所能想到的就是：

\n\t

但我需要的输出：

Color and Size - Dark Blue|Small, Dark Blue|Medium, Dark Blue|Large, Dark Blue|X-Large



Color and Size - Black|Small, Black|Medium, Black|Large, Black|X-Large, Ocean|Small, Ocean|Medium, Ocean|Large, Ocean|X-Large






Color and Size - Black|Small, Black|Medium, Black|Large, Black|X-Large, Black|2X-Large, Stone|Small, Stone|Medium, Stone|Large, Stone|X-Large, Stone|2X-Large








// end output

我建议将“块”放在一起，并在函数中运行替换，例如：

// Getting a block
var regex = /Color and Size[\s\S]*?(?=Color and Size|$)/gi;

// Taken from http://stackoverflow.com/q/29339480/1578604 to repeat string
String.prototype.repeat = function( num ) {
    return new Array( num + 1 ).join( this );
}

var results = text.replace(regex, function(m) {
    // Get number of line breaks
    var lb = m.split("\n").length - 1;
    // Now remove newlines and tabs, then add the linebreaks at the end
    return m.replace(/\n\t/g, ", ") + "\n".repeat(lb);
});
