It is possible to use a single instance of the Xalan Transformer to compile multiple XSLT stylesheets and make them available for repeated use against incoming XML documents. Note that when you terminate the Xalan Transformer, any parsed documents and compiled XSLT transforms will become unusable. I've been looking at how to capture compiled XSLT transforms into storage outside of the virtual process address space. Since you have a large number of XSLT transforms, I hope that virtual address space won't be an issue. Steven J. Hathaway
