Hi there xslt gurus,
i am kinda new to xslt and having difficulty to implement my some iterations. i need to recreate an xml file by using xslt. here is the sample xml file(input for xslt)

<Flights>
 <Flight>
   <FlightLeg >
     <BookingClassCodeList>
       <BookingCode Value="C" />
       <BookingCode Value="Y" />
     </BookingClassCodeList>
   </FlightLeg>
  </Flight>
  <Flight>
   <FlightLeg >
     <BookingClassCodeList>
       <BookingCode Value="C" />
     </BookingClassCodeList>
   </FlightLeg>
   <FlightLeg >
     <BookingClassCodeList>
       <BookingCode Value="A" />
       <BookingCode Value="B" />
     </BookingClassCodeList>
   </FlightLeg>
  </Flight>
<Flights>
AS you can see, there can be 1 or more flightlegs per flight. I need to do sth by xslt so that:
- instead of first flight node there will be 2 new flight nodes with bookingclasscode values are assigned as attribute to flightleg
 <Flight>
   <FlightLeg booking="C" />
  </Flight>
  <Flight>
   <FlightLeg booking="Y" />
  </Flight>
-- and instead of second flight node there will be 2 new flight nodes(combination of booking classes of flightlegs) with related attributes assigned
 <Flight>
   <FlightLeg booking="C" />
   <FlightLeg booking="A" />
  </Flight>
<Flight>
   <FlightLeg booking="C" />
   <FlightLeg booking="B" />
  </Flight>

I feel like this can be implemented by xslt since it is recursive based programming, but i couldn't figure it out. If you can help me i really appreciate it. thanks in advance!

I am not sure I completely understand your what you need, but I gave it a shot:

[code]<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions" exclude-result-prefixes="fn xs">
    <xsl:output method="xml" encoding="UTF-8" indent="yes"/>
    <xsl:template match="/Flights">
        <Flights>
            <xsl:for-each select="Flight">
                <Flight>
                    <xsl:for-each select="FlightLeg">
                        <xsl:for-each select="BookingClassCodeList">
                            <xsl:for-each select="BookingCode">
                                <FlightLeg>
                                    <xsl:for-each select="@Value">
                                        <xsl:attribute name="booking">
                                            <xsl:value-of select="xs:string( . )"/>
                                        </xsl:attribute>
                                    </xsl:for-each>
                                </FlightLeg>
                            </xsl:for-each>
                        </xsl:for-each>
                    </xsl:for-each>
                </Flight>
            </xsl:for-each>
        </Flights>
    </xsl:template>
</xsl:stylesheet>[code]

thx for your quick response bonekrusher, but it loses soma data. I mean it has to calculate all combinations per booking class and per leg. That is,

if there are 3 flightLegs for a flight:

leg1{A, B, C} // 3 booking class codes for leg1
leg2{A, Y} // 2 booking class codes for leg2
leg 3{E,F,G} // 3 booking class codes for leg3

then in new xml file, there must be 3 x 2 x 3 = 18 new flight elements
3 example of newly created 18 flight nodes

<Flight>
   <FlightLeg booking="A" />
   <FlightLeg booking="A" />
   <FlightLeg booking="E" />
  </Flight>
<Flight>
   <FlightLeg booking="A" />
   <FlightLeg booking="A" />
   <FlightLeg booking="F" />
</Flight>
<Flight>
   <FlightLeg booking="B" />
   <FlightLeg booking="Y" />
   <FlightLeg booking="F" />
</Flight>
... and so on..am i more clear now?

no not really. Do me a favor. Post a new input XML. Then show desired result. Make sure its exacly like you want it.

Your example above shows leg1{A, B, C} but the desire results do not have the same attributes..e.g. you show the first flight with 3 legs "A,A,E' in your desired results.

maybe I am missing something.
