There are quite some XSLT processors which can do streaming processing.

DataPower processor does even allow for "partial streaming" which means it
can deal with
more complex transformations than a streaming processor can in a "streaming
like" fashion.
But DataPower XSLT processor is only available as an appliance, not as pure
software.

Subject:    [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.
