coodinate tranformation

hello,
I have a gml coordinate that I want trosform it in svg coordinate, using xsl transformation.
I validated my files with xml exchange editor and the saxon processor.
I used the tokenize function like: select="saxon:tokenize(*/gml:coordinates, '\s')", the result thet I get is a list of all coordinates without transformation,from this  I want know what parameter must I use:
e.g I have:gml:coordinates>0 50, 70 60, 80 90</gml:coordinates>
select="saxon:tokenize(*/gml:coordinates, '\s')"
the current result: <path d="0 50, 70 60, 80 90"/>
how can I obtain: <path d="M0 50, L 70 60, L 80 90" />
thank you
