xsl filter

good afternoon everyone:
I have created 'list' files 'on the fly' using an asp page to transform the
data results with the appropriate xsl sheet.  There are a total of 6 'lists'
at this time (I'm sure there will be more) Now I would like to filter the
resulting xml/xsl output based on field/attribute names and the user
criteria. (eg filter by 'lastname' beginning with 'm').  should I use the
xsl:copy command? is this the simplest way of doing it? How do you apply the
'filtering criteria ('m')?
If anyone has done something similar, I would appreciate any comments.
