Only with `enum xmldata = import("file.xml");`, but you have to pass
the -J switch and a directory path for the location of the file. E.g.:
module test;
enum xmldata = import("file.xml");
void parse(string data)() { }
void main() {
parse!(xmldata)();
}
$ dmd -J. test.d
"." is short for the current dir of course.
