xsl looping problem

i have a xml which has data in blocks(diff elements seperated only by attribute). I have take one value from each block and put them together in a seperate block.The xml looks like


<input>
<input.voltage counter="0">
<value>1</value>
</input.voltage>
<input.voltage counter="1">
<value>2</value>
</input.voltage>
<input.voltage counter="2">
<value>3</value>
</input.voltage>
</input>

<output>
<output.voltage counter="0">
<value>4</value>
</output.voltage>
<output.voltage counter="1">
<value>5</value>
</output.voltage>
<output.voltage counter="2">
<value>6</value>
</output.voltage>
</output>

i am looking for a output in this format:
<DataArray>
<DataCell>1</DataCell>
<DataCell>4</DataCell>
</DataArray>
<DataArray>
<DataCell>2</DataCell>
<DataCell>5</DataCell>
</DataArray>
<DataArray>
<DataCell>3</DataCell>
<DataCell>6</DataCell>
</DataArray>

Any help , pointers will be appreciated

thanks

You need to use XSL - if you search the net you'll probably find some sites that mention it. Or you could just keep checking this thread until some kind person does your job for you.
