Hi
I am completely new to XSLT transformation, so I hope someone can help
me.
I have quite a big and complex structure that I need to flatten (the
output of the project requires a flat xml file - don't ask me why)
So I need to flatten the structure, but I also need to use the former
tags-names to name the new structure.

As it looks now:
<?xml version=3D"1.0" encoding=3D"UTF-8"?>
	<OfferHead>
		<Offerprice>
			<Quantity>
				<unitCode>m=B2</unitCode>
				<QuantityDescription>ca. v=E6gtet areal</QuantityDescription>
				<value>1</value>
			</Quantity>
			<UnitPrice>
				<Licitation>0</Licitation>
				<Netto>0</Netto>
				<Brutto>0</Brutto>
				<CostSavings>0</CostSavings>
				<ContractPrice>0</ContractPrice>
			</UnitPrice>
			<Sum>
				<Licitation>0</Licitation>
				<Netto>0</Netto>
				<Brutto>0</Brutto>
				<CostSavings>0</CostSavings>
				<ContractPrice>0</ContractPrice>
			</Sum>
			<currencyID>DKK</currencyID>
		</Offerprice>
		<BasisForOffer>
			<BaseIndex>111.19999694824219</BaseIndex>
			<CurIndex>111.19999694824219</CurIndex>
			<BaseDate>2007-04-10T00:00:00</BaseDate>
			<CurDate>2007-04-21T00:00:00</CurDate>
		</BasisForOffer>
</OfferHead>

This is what I want it to look like (the underscores just make it
easier to read.. don't really need them)

	<OfferHead>
		<Offerprice_Quantity_unitCode>m=B2</Offerprice_Quantity_unitCode>
		<Offerprice_Quantity_QuantityDescription>ca. v=E6gtet areal</
Offerprice_Quantity_QuantityDescription>
		<Offerprice_Quantity_value>1</Offerprice_Quantity_value>
		<Offerprice_UnitPrice_Licitation>0</Offerprice_UnitPrice_Licitation>
		<Offerprice_UnitPrice_Netto>0</Offerprice_UnitPrice_Netto>
		<Offerprice_UnitPrice_Brutto>0</Offerprice_UnitPrice_Brutto>
		<Offerprice_UnitPrice_CostSavings>0</
Offerprice_UnitPrice_CostSavings>
		<Offerprice_UnitPrice_ContractPrice>0</
Offerprice_UnitPrice_ContractPrice>
		<Offerprice_Sum_Licitation>0</Offerprice_Sum_Licitation>
