我有以下问题，只是在前一篇文章中部分解决了：我有一个特定类型的文本文件，这个文件包含一系列患者的放射治疗的Roi信息，我想确定包含一系列数字（在上一篇文章中实现的目标）的一部分文本，编辑这些数字的一部分并将其保存在原始文件中。 我附上了Roi文件的副本：

我感兴趣的是只提取Roi：Couch为其所有曲线定义的段落部分中的数值（x，y，z）。使用正则表达式，我能够提取这些值，但也提取不需要的值，例如：
// Curve 1 of 2
//----------------------------------------------------
curve={
flags = 20;
block_size = 32;
num_points = 6;
points={
将这些值添加到所需的值：1 2 20 32 6（不需要的）-23.5328 6.25885 40等等（所需）。 将这些值加到所需的值：1 2 20 32 6（不需要的）-23.5328 6.25885 40等等（所需）。 最后一步是改变已知值的x和y - ＆gt; -123.5328 106.25885并输入这些新值而不是原始文件中的原始值。 通过这种方式，我在笛卡尔平面上的Roi的x，y位移。 感谢您提供给我的所有帮助。
