上記の xml の XSLT は次のとおりです。
<?xml version="1.0" encoding="utf-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

<!-- Match document root : add hotels element and process each children node of result -->
<xsl:template match="/">
<hotels>
<!-- We assume that the XML documents are always going to follow the structure:

<CurrencySymbol>£</CurrencySymbol>
<NoOfRoomsAvailable>4</NoOfRoomsAvailable>
<RatePerDay>27 Mar 2013_79.00</RatePerDay>
</hotel_rooms>
<Rate>
<RoomRatePlan>Advance</RoomRatePlan>
<numeric_price>79.00</numeric_price>
<RoomRatePlan>Standard</RoomRatePlan>
