XML Processing with Python

12.7. Tree Cut-and-Paste

Pyxies provides a Cut method that allows you to cut a piece out of a tree—the cutting is itself an xTree object. The PasteDown and PasteRight methods can be used to insert a tree into another tree. The PasteDown method positions the inserted tree, as the first child of the active node. The PasteRight method positions the inserted tree to the right of the active node.

In the following example, the b element is moved to the left of “Hello” with cut and paste operations.
