[xsl] Are there any XSLT processors that can incrementally input the XML data?

Hi Folks,

I have a simple but large XML document containing almost 100 million bank
withdrawals/deposits:

<transactions>
    <withdrawal>30</withdrawal>
    <deposit>40</deposit>
    <deposit>50</deposit>
    <withdrawal>20</withdrawal>
    <withdrawal>45</withdrawal>
    <deposit>80</deposit>
   ...
</transactions>

I want my XSLT program to start at the first transaction:

    <withdrawal>30</withdrawal>

and then sequentially process the following siblings.

I want the <withdrawal> and <deposit> elements to be input on demand.

Are there any XSLT processors that can incrementally input the XML data? That
is, the XSLT processor inputs just the number of XML elements currently
requested by the XSLT program, processes those elements, and then outputs the
results? All this is done with little or no in-memory storage.
