This function iterates as many times as the value of the $indentation class variable, and for each iteration it adds the $indentationValue class variable to $xml, and returns it.

此函数需要迭代的次数与 $indentation 类变量值相同，对于每次迭代，它将 $indentationValue 类变量添加到 $xml，并将后者返回。

This recursive function works fine, but it has one main shortcoming -- every iteration of the recursion will be passing the same value for the-string.

这个递归函数能很好地工作，不过它有一个主要的缺点 —— 递归的每一次迭代都要为 the-string 传递 相同的值。

The smaller the value of the merit function is, the closer the iteration point is to the solution.

当价值函数的值越小时，迭代点越靠近最优解。
