Java UML editable component/lib

Question

I have a task where we need to generate UML(or similar) from XML and will be able to edit text, property type and drag dependency row. But I can't find any Java lib or component wich will allow me to do such. For example PlantText is a good lib but it does not allow to make edit.

If someone known such lib/compoment please share. Thanks

EDIT: Sorry, maybe I wasn't wrote clear. Actually, I need library which I can implement into my project, and after I will be able to generate UML from my project, then edit it and save into XML.

draw.io is very good site where you can create (not only) UML's and save them to XML file so in future you can edit it. The drawback is it is not automatic and must be drawn from scratch.
