RE: [xsl] XSL transformations on hundreds of XML documents held up against single large XML document

["Michael Kay" <mike@xxxxxxxxxxxx>]

This depends on the API of your processor, but I would expect you to be able
to construct a stylesheet parameter whose value represents a node-set, being
the set of document nodes that the stylesheet is to process. In the case of
a Microsoft processor, I'd expect this normally to be a DOM NodeList -
though I can't be certain without checking that a DOM NodeList allows nodes
from multiple documents. 

So you should be able to create each of your A1..An documents as a DOM
Document, construct a NodeList containing the document nodes (or the
document elements if you prefer), and pass this to a stylesheet parameter
that you then treat as a node-set.
