How to fast get a hierarchy of accounts in gnucash ?

[Raphaël Maville]

If I still have an accounts hierarchy already written in text, can
gnucash "eat" it ? Is a tool for this ?

Example: Accounts:
Account A
Account B
	Subaccount B0
	Subaccount B1
	Subaccount B2
	Subaccount B3
Account C
	Subaccount C0
		Subsubaccount C00
	Subaccount C1
etc.

If I have it in text format, will gnucash have it ?

If I convert it in XML format, will gnucash have it ? And if the <guid>
is empty, will gnucash auto-create it .
