How to use Choose condition on XSLT variable

Questions
1

Hello Guys,

I am new to XSLT , So putting up maybe really basic question .

Well I will keep it short ,

What I have to do is create three dummy variables (Which will be updated from server–LDAP ) and compare this against another set of variables ,After comparison I have to update the result in another variable and return that variable ,

Here is the SUDO code .

If ( A_Div_Code contain '$DIVISION_CODE') and  ( A_Dept_Code contains '$DEPT_CODE') and (A_job_Level contains '$JOB_LEVEL)
MP_GROUP='A'
If (C_Div_Code contain '$DIVISION_CODE') and  (C_Dept_Code contains '$DEPT_CODE') and (C_job_Level contains '$JOB_LEVEL)
MP_GROUP='A,C'

and the variables will be like this

1.DIVISION_CODE : This variable will store the Division code received from LDAP for a user/file_id.
Example :DIVISION_CODE":"48
2.DEPT_CODE : This varaible will store the Department code received from LDAP for a user/file_id.
Example :DEPT_CODE":"LT"
3.JOB_LEVEL : This variable will store the Job level received from LDAP for a user/file_id 
Example :JOB_LEVEL":"4B

MI_GROUP : Which basically we be finding logically and sending to backend web server.

Based on this I created following XSLT file ,

<?xml version="1.0" encoding="UTF-8" ?>

	exclude-result-prefixes="xs xdt err fn">

	<xsl:output method="xml" indent="yes"/>
	
	<xsl:variable name="DIVISION_CODE" select="'47'" /> 
	<xsl:variable name="DEPT_CODE" select="'KT'" /> 
	<xsl:variable name="JOB_LEVEL" select="4B''" /> 

	
<xsl:variable name="MI_GROUP"  /> 
	
	<xsl:variable name="A_Div_Code">
	47,48,49,50
	</xsl:variable>
	<xsl:variable name="A_Dept_Code">
	KT,VT,SF,MQ
	</xsl:variable>
	<xsl:variable name="A_Job_Level">
	4B,2B,7B
	</xsl:variable>
	
	<xsl:variable name="C_Div_Code">
	12,76,31
	</xsl:variable>
	<xsl:variable name="C_Dept_Code">
	ML,KL,KO
	</xsl:variable>
	<xsl:variable name="C_Job_Level">
	4C,2C,7C
	</xsl:variable>
	
	<xsl:template match="/">
		
		<xsl:apply-templates/>
	</xsl:template>

</xsl:stylesheet>

So basically I will have to compare the Three variable against those department codes and update the MI_GROUP variable
