切碎是将XML数据放进关系列中，但去掉了它的XML特征，这意味着原来XML文档中数据的层次关系丢失了。

Shredding puts XML data into relational columns but strips it of its XMLness, meaning the hierarchical relationships among the data in the original XML document are lost.

我还向您展示了第二种方法，可以快速分组复杂的层次结构，使其多边形可编辑，而不会丢失动画，甚至保留一些过程特征。

I also show you a second way to quickly group complex hierarchies, make their Polygons editable without losing the animation and even keeping some procedural features.
