How do I change a XSL style sheet to group data togeth

Good day,
My knowledge of XML is next to none and I only have one XSL code to use.
I also assume I may be using incorrect jargon and hope you will
understand what I need.

I have an XSL style sheet to convert the XML flat file. I need to
change the style sheet so it groups certain data together under one
heading. I need to be able to do this as the system I upload the file
to do not accept the information as presented and continuously gives me
an error. What I am trying to say is that the result information
under sample grouped together where the sample information is the
same.

<sample sample_date_time="20070101" imis_cp_ext="2300" cp_name="NEUTRA.
SUMP WTPE" dischg_sample_cd="20070101" sample_comment="">

</sample>
