Drop a LineStringElement to a series of LineElement(s)

Hi all,

I have a that has lineStrings in it. I want to convert all the line strings into lineElement(s) corresponding to the constituent lineStringElement segments lengths and 

positions. I have done it manually using the break element,  "7-2" command. I want to find a way to do this programatically, as there are numerous LineStringElements in my drawing and it would take ages to complete.

I tried dropping the LineStringElement, but it always says " Nothing to drop", so I am not sure how to fix this.

Thanks
