Buenas tardes que tal, deseaba saber si alguien sabe como pasarle valores a un archivo . xml
para el siguiente ejemplo
<?xml version="1.0" encoding="UTF-8"?>
<plusgradeOfferRequestToken>
<flights>
<flight>
<departureDate>2011-10-15</departureDate>
<origination>rrr</origination>
<destination>ggg</destination>
<flightNumber>104</flightNumber>
<offerUrl>
https://upgrade.plusgrade.com/offer/ yourPID/offer/upgrade/YourAPIKey</offerUrl>
<imageUrl>
https://upgrade.plusgrade.com/offer/ yourPID/offer/tag/YourAPIKey</imageUrl>
</flight>
<flight>
<departureDate>2011-10-17</departureDate>
<origination>YYY</origination>
<destination>XXX</destination>
<flightNumber>103</flightNumber>
<offerUrl>
https://upgrade.plusgrade.com/offer/ yourPID/offer/upgrade/YourAPIKey</offerUrl>
<imageUrl>
https://upgrade.plusgrade.com/offer/ yourPID/offer/tag/YourAPIKey</imageUrl> </flight>
<flights>
</plusgradeOfferRequestToken>
como seria la forma para crear el .xml y luego para enviarle los valores de un archivo txt
