Default Prevent displaying duplicate infromation in xsl

I wonder if you could help me solve an xsl problem.

I have the following xml string:

            <project code=”1” name=”company1” costName=”cost1” supplierName=”ABC Ltd”/>

            <project code=”1” name=”company1” costName=”cost2” supplierName=”xxx Ltd”/>

            <project code=”2” name=”company2” costName=”cost1” supplierName=123 Ltd”/>


What I really need to do is produce a report that shows the supplier name for each company. The cost name will be a column on the report and not a row.


Company Cost1 Cost2

Company1 ABC Ltd XXX Ltd

Company2 123 Ltd

Can it be done? If so, how?

This problem is known as grouping. In XSLT 2.0 it's quite easy using the <xsl:for-each-group> instruction. In XSLT 1.0 it's quite tricky, but achievable using the Muenchian grouping technique described at http://www.jenitennison.com/xslt/grouping
