Set up your criteria file like this:
<criteria>
<category grade="1">
<criterion>country != 'USA'</criterion>
<criterion>age > 20 and age < 25</criterion>
<criterion>occupation = "doctor" or occupation =
"engineer"</criterion>
</category >
<category grade="2">
<criterion>country = 'UK'</criterion>
<criterion>age < 50</criterion>
<criterion>occupation = "dentist"</criterion>
</category >
</criteria>
This is probably as easy for your users to edit as anything is likely to
be.
Write a stylesheet that transforms this file into a stylesheet
containing code such
<xsl:template match="Employee
[country != 'USA']
[age > 20 and age < 25]
[occupation = 'doctor' or occupation = 'engineer']">
<p>Grade 1</p>
</xsl:template>
<xsl:template match="Employee
[country = 'UK']
[age < 50]
[occupation = 'dentist']">
<p>Grade 2</p>
</xsl:template>
Then run this generated stylesheet against your source XML file.
