If so, then if you are not expecting any why not ignore them? (And comments.) Then all you need to wait for is the next '<?xml ... ?>' or <!DOCTYPE or element tag - that is, the next document. > More importantly, you don't want to have to parse an entire document > just to find out where it ends because that forces your system into > linear processing -- on a busy server, it is absolutely necessary to > be to isolate the documents/packets quickly and pass them off to > separate threads (or even separate boxes) for parsing and processing. You may be able to *parse* parts of the document before the entire document has completely arrived, but it is surely wrong to *process* the document because you don't yet know if it's well-formed or valid. Some of the parsing you did in one process might be invalidated as the result of another process. Regards, Mark xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
