Hi -

In your XML there appears to be <Class> elements that hold Percentage attributes, along with a single <Grade> element that also holds a Percentage attribute. I assume that this is intentional and not a cut-and-paste error.

I would use the following:

<xsl:variable name="unique-Percentage"
           select="/School/Classes/Class/*[(self::Grade or self::Class) and @Percentage = '85']" />

This will generate a node-set containing all the <Class> or <Grade> elements that have a Percentage attribute equal to 85.

You shouldn't use //Class (a short-form of descendant-or-self::Class) because it's inefficient. You also can't use /School/Classes/Class because this will only consider the <Class> elements with the ClassId attribute.

Hope this helps.

- Tim
