Creating multiple xmls using xslt1.0

Hi experts,

I have an xml file like this:

<Data>
       <Row>
       	<Cell1>text 1</Cell1>
      	 <Cell2>text 2</Cell2>
       </Row>
       <Row>
       	<Cell1>text 3</Cell1>
      	 <Cell2>text 4</Cell2>
       </Row>
      <Row>.....<Row>
     <Row>.....<Row>
.....
</Data>



And I have thousands of <Row> elements like this. For the first 50 rows, I
should be able to create an output xml with name Data1.xml, for next 50 rows
output xml should be data2.xml, for next 50 rows output should be data3.xml
and so on until all the rows are complete. And I have to achieve this with
XSLT 1.0. Can anybody please help?

Thanks,
Siddhi
