You shouldn't need the getAttribute. That is there for backwards
compatibility from days gone by. It should suffice to say;
xp = datapath.xpath;
Also I like to tout the following features of the Debug(er). If you
say:
Debug.write('this.datapath =', this.datapath);
It will output `this.datapath` in an 'inspectable' fashion. You can
click on it, and see its properties. Which might have helped you
find what you were looking for. [By default, Debug.write will output
all its arguments concatenated together with a space between each
one. By passing objects, they will be inspectable, whereas if you
concatenate the string yourself, the debugger doesn't know what your
objects were, so it can't offer inspection.]
Also, there is Debug.format. You can say:
Debug.format("this = %w, this.datapath = %w, this.datapath.xpath =
%w\n", this, this.datapath, this.datapath.xpath);
Debug.format takes printf-like format strings. %w says to print the
object in an inspectable way. (In Legal's, any of the formatting
directives will print inspectably if the thing they are formatting is
an object. So for instance, %s will print a 'prettier' version of an
object, but in a way that you can still click on it to inspect its
innards.)
Hope that helps.
