Grouping problem

[wxdqz]

I have an xml something like this:

<class name=class1>
<parameters>
<parameter name="p1" datatype="string">val1</parameter>
<parameter name="p2" datatype="dec">val2</parameter>
<parameter name="p3" datatype="string">val3</parameter>
<parameters>
</class>
<class name=class2>
<parameters>
<parameter name="p4" datatype="string">val4</parameter>
<parameter name="p5" datatype="dec">val5</parameter>
<parameter name="p6" datatype="string">val6</parameter>
<parameters>
</class>

I want to group the data something like this ...in a single input field
name=p1,p2,p3
datatype=string,dec,string
values=val1,val2,val3

Is it possible to do this in xslt?

Thanks
