I meant to say "copying repeating values" not just copying values.
I asked about filler vs. browser because if you are using filler you could try the OpenForm command.
I'm assuming when you save your form, you know the name of it? That is what I am suggesting you pass to your new form, so you know what current form the new form was opened from.
qRules has CopyTable that can copy repeating data - so if you created a data connection to an XML of the same type, you could use ChangeConnectionUrl to modify that to open the correct form, query to get the data, then use CopyTable (or Insert with other rules, or Transform) to get the data into your target form.
