Xara does have an eraser function as explained in this Xara Xone TIP:

Xara’s eraser function TIP: Many new users ask if Xara has an eraser tool. The answer is not as such. But there is a “Redraw” function that has the same effect. With a shape selected, select the Freehand and Brush Tool. When you move the cursor over a control point a small tilde (~) appears. Click and drag from any control point to any other control point. The smaller of the two shapes will be erased as shown above. Xara also has an “Eraser” function that works when drawing with the Freehand and Brush Tool. While your line is still active, hold down the Shift key and the Pencil icon flips over to the eraser side and as you move the eraser back over the line, it is erased.
