Newbie XSLT question

[fedehf]

Hello, I'm new with XSLT and I got asigned to do an xslt spreedsheet at work but I got stuck in this point:
XML:

Code: Select all

  <Intro 	BillingCycles="12 Billing Cycles" 

  FlipDate="None" 

  Tier="1">

    Purchase=0.00:F

    BT=0.00:F

    CC=0.00:F

    BillingCycles=12 Billing Cycles

    FlipDate=None

    <Purchase  	APR="0.00" />

    <BT APR="0.00"  />

  </Intro>



  <Intro 	BillingCycles="12 Billing Cycles" 

  FlipDate="None" 

  Tier="2">

    Purchase=0.00:F

    BT=0.00:F

    CC=0.00:F

    BillingCycles=12 Billing Cycles

    FlipDate=None

    <Purchase  	APR="0.00" />

    <BT APR="0.00"  />

  </Intro>

  <Intro 	BillingCycles="12 Billing Cycles" 

  FlipDate="None" 

  Tier="3">

    Purchase=0.00:F

    BT=0.00:F

    CC=0.00:F

    BillingCycles=12 Billing Cycles

    FlipDate=None

    <Purchase  	APR="0.00" />

    <BT APR="0.00"  />

  </Intro>





<Goto 	BillingCycles="None" 

  FlipDate="None" 

  Tier="1">

    Purchase=14.24:V

    BT=14.24:V

    CC=14.24:V

    BillingCycles=None

    FlipDate=None

    <Purchase 	APR="14.24" />

    <BT APR="14.24" />

  </Goto>



<Goto 	BillingCycles="None" 

  FlipDate="None" 

  Tier="2">

    Purchase=14.24:V

    BT=14.24:V

    CC=14.24:V

    BillingCycles=None

    FlipDate=None

    <Purchase 	APR="14.24" />

    <BT APR="14.24" />

  </Goto>

<Goto 	BillingCycles="None" 

  FlipDate="None" 

  Tier="3">

    Purchase=14.24:V

    BT=14.24:V

    CC=14.24:V

    BillingCycles=None

    FlipDate=None

    <Purchase 	APR="14.24" />

    <BT APR="14.24" />

  </Goto>

I have to select the Intro/@Tier that applies with:
IF<INTRO;PURCHASE;APR> != “None” or is NOT equal to <GOTO;PURCHASE;APR> but from the same Tier.
Example <INTRO[@Tier = 1];PURCHASE;APR> != "None" and <GOTO[@Tier = 1];PURCHASE;APR>

This is what I got so far:

Code: Select all

<xsl:variable name="IntroTiers" select="Intro[@Tier = * and Purchase/@APR!='None' and not(Purchase/@APR !=  /Goto[@Tier = *]/Purchase/@APR) ]/@Tier" /> 

This select doesn't work because the second * is selecting "any Tier" and not the same Tier that the first * . I can not think of a way to compare differents nodes from the same Tier.
BTW, I can't change the XML, I have to work with that one

Sorry for my english.

Thanks

Could we see the context in which it is used? Did you need to select all of the @Tier nodes?

It might take 2 steps. I think it'd be something closer to:
select = "Intro[@Tier != '' and Purchase/@APR!='None']/@Tier[not( (Purchase/@APR != //Goto[@Tier = *]/Purchase/@APR))]
