SQL CAST from XML

I try to CAST a XML Value e.g. 0.19 to INT and calkulate it with * 100.

But I get an error like: Error by converting nvarchar-Value '0.19' in the INT Type.

This is the Code: (but the Row with the "CAST" is the Problem)

insert into BELEGP(Kennung, Belegtyp, Belegnummer, Posnummer, Postext, Zeilentyp, Menge, Steuerprozent, Eingabemenge, Editmenge, Artikelnummer, Bezeichnung, Preismenge, Einzelpreis, Gesamtpreis, Netto, Adressnr)

   SELECT  NEWID() as Kennung,
       'F' as Belegtyp,
       Myorder.j.value('OrderNumber[1]', 'varchar(50)') as Belegnummer,
       ROW_NUMBER() OVER (ORDER BY Myorder.j.value('OrderNumber[1]', 'varchar(50)')) as  Posnummer,
       ROW_NUMBER() OVER (ORDER BY Myorder.j.value('OrderNumber[1]', 'varchar(50)')) as  Postext,
       'A' as Zeilentyp,
       MyItem.j.value('Quantity[1]', 'varchar(50)') as Menge,
       CAST(Cast(MyItem.j.value('TaxRate[1]', 'nvarchar(50)') as nvarchar) as INT) * 100 as Steuerprozent,
       MyItem.j.value('Quantity[1]', 'varchar(50)') as Eingabemenge,
       MyItem.j.value('Quantity[1]', 'varchar(50)') as Editmenge,
       MyItem.j.value('Id[1]', 'varchar(50)') as Artikelnummer,
       MyItem.j.value('Name[1]', 'varchar(50)') as Bezeichnung,
       MyItem.j.value('TotalPrice[1]', 'varchar(50)') as Preismenge,
       MyItem.j.value('TotalPrice[1]', 'varchar(50)') as Einzelpreis,
       MyItem.j.value('TotalPrice[1]', 'varchar(50)') as Gesamtpreis,
       MyItem.j.value('UnityPrice[1]', 'varchar(50)') as Netto,
       Myorder.j.value('CustomerNumber[1]', 'varchar(50)') as Adressnr

   FROM (
 SELECT CAST(x AS XML)
 FROM
 OPENROWSET( BULK 'D:\shop\xml\Bestellungen.xml',SINGLE_BLOB) AS k(x))
 AS k(x)
 CROSS APPLY x.nodes('Orders/Order') AS MYorder(j)
 CROSS APPLY x.nodes('Orders/Order/Addresses/BillingAddress') AS MYAddresses(j)
 CROSS APPLY x.nodes('Orders/Order/LineItems/LineItem') AS MYItem(j)

Even if you could cast value 0.19 to int it would be rounded to 0. I think you have to fetch value as decimal and then do you conversion:

declare @Data xml = '<TaxRate>0.19</TaxRate>'
select cast(@Data.value('TaxRate[1]', 'decimal(29, 2)') * 100 as int)
