我希望有人可以通过指着我与Muenchian分组的方向是正确的帮助我。

我在下面的表格数据：

等等...

我试图让输出分组如下： 

liscadGM04
                pntRef  GM03    Min azimuth=:”70.0109”
                pntRef  GM03    Max azimuth=:”70.0117”
liscadGM04
                pntRef  SAW53  Min azimuth=:”107.3429”
                pntRef  SAW53  Max azimuth=:”107.3442”
liscadGM04
                pntRef  HB402   Min azimuth=:”309.3845”
                pntRef  HB402   Max azimuth=:”309.3857”

                Etc…..
liscadSAW160
                pntRef  SAW61  Min azimuth=:”10.0112”
                pntRef  SAW61  Max azimuth=:”70.0112”

            Etc…

我挣扎着爬了XSL代码嵌套这样的，这里是我的软弱试图日期的摘录：

任何人都可以点我在正确的方向？

Answer 1:

好吧，试试这个基于密钥的解决方案。 原来，因为你不被setupID分组，它只是分组的一个级别，而不是多级分组，所以只需要一个键。 我没有注意到，当我开始与基于可变分组根据您的问题标题。 它产生的相同的结果作为我的基于可变的解决方案。 它会占用内存少，希望少足以在你的环境中工作。

还要注意你的最小值/最大值的计算是矫枉过正和我的两个解决方案，提出一个更简单的方法。
