Is it possible to delete all files in a directory using XML?

Is it possible to delete all files in a directory but not the actual directory using XML?

Here's what I tried:

<TEST dir="D:\Users\NAME\Desktop\TEST" file="*.docx">
  <find find=". -name "*.docx"; -type f|xargs rm -f" />
</TEST>

Please tell me if it is at all possible to do this.

If not is it possible to run a Java file through a XML file?
