conditional match for multiple attributes using XSLT - xslt

Question

Below is the input XML
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:ces:names:specification:ces:schema:all:4:0">
<soapenv:Header/>
<soapenv:Body>
<ces:ShipNotice Version="4.0" xmlns:ces="urn:ces:names:specification:ces:schema:all:4:0">
<ces:Header>

<ces:PartnerIdentifier Agency="AGIIS-EBID">8049915600000</ces:PartnerIdentifier>
</ces:PartnerInformation>
</ces:Buyer>

I need to test for incoming request if the value of Buyer and Shipto and Billtoparty can be AGIIS-EBID or EAN.
I did ask similar question before
Previous thread
In previous thread the value I was testing was same.
<xsl:when test="
($Buyer='AGIIS-EBID' and $Shipto='AGIIS-EBID' and $Billto='AGIIS-EBID')
or ($Buyer='EAN' and $Shipto='EAN' and $Billto='EAN')
or ($Buyer='GLN' and $Shipto='GLN' and $Billto='GLN')">
My question is how to test the condition for Agency#Buyer, Agency#Shipto, Agency#billtoParty if the value will be AGIIS-EBID or EAN
I mean in the soap request always Buyer,Shipto, billtoparty can have different sequence like Buyer=AGIIS-EBID,Shipto=EAN,billtoparty=AGIIS-EBID or Buyer=EAN,Shipto=EAN,billtoparty=AGIIS-EBID or Buyer=AGIIS-EBID,Shipto=EAN,billtoparty=EAN
I was thinking to do something like this
<xsl:when test="($Buyer='AGIIS-EBID' and $Shipto='AGIIS-EBID' and $Billto='AGIIS-EBID') or ($Buyer='AGIIS-EBID' and $Shipto='EAN' and $Billto='AGIIS-EBID')($Buyer='AGIIS-EBID' and $Shipto='AGIIS-EBID' and $Billto='EAN') or ($Buyer='EAN' and $Shipto='EAN' and $Billto='EAN')">
Can anyone please advise for different approach?
Update for the questions.
#michael.hor257k I am sorry.. three agency objects (Buyer, ShipTo and BillToParty), You are correct it can be positive ( AGIIS-EBID or EAN).. If it is positive I need to accept the message, however if its negative I need to reject the message saying #Agency didn't match the AGIIS or EAN for buyer and Shipto and Billparty.
The problem I am facing is Agency objects (Buyer, ShipTo and BillToParty) should match ( AGIIS-EBID or EAN), but in what manner they come I don't know.
Below are the different ways values may get assigned.
Eg: (Buyer='AGIIS-EBID'and Shipto='EAN'and Billtoparty='AGIIS-EBID') or (Buyer='EAN' and Shipto='EAN' and Billtoparty='AGIIS-EBID') or (Buyer='AGIIS-EBID' and Shipto='EAN' and Billtoparty='EAN')` so on ....
One more thing I want to add I have to check the positive condition for #Agency in Buyer and Shipto and BilltoParty

Answer 1

My goal to test every time $Buyer= 'AGIIS-EBID' or 'EAN' and $Shipto=
'AGIIS-EBID' or 'EAN' and $Billto= 'AGIIS-EBID' or 'EAN'
Okay, so why don't you just spell that out as;
<xsl:when test="
($Buyer='AGIIS-EBID' or $Buyer='EAN')
and
($Shipto='AGIIS-EBID' or $Shipto='EAN')
and
($Billto='AGIIS-EBID' or $Billto='EAN')">

Answer 2

How about:
<xsl:variable name="Buyer_ok" select=" $Buyer = 'EAN' or $Buyer = 'AGIIS-EBID' " />
<xsl:variable name="Shipto_ok" select=" $Shipto = 'EAN' or $Shipto = 'AGIIS-EBID' " />
<xsl:variable name="Billto_ok" select=" $Billto = 'EAN' or $Billto = 'AGIIS-EBID' " />
:
:
<xsl:when test=" $Buyer_ok and $Shipto_ok and $Billto_ok "> . . .</xsl:when>
