[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] progressive translation
 As I understand it, the general XSL translation process cannot emit anything until the entire incoming XML document has been parsed because the translation rules can potentially require access to the full parse tree. However, there will be some applications where "chunks" of incoming XML can be processed in relative isolation. The potential benefit is to improve response time when a user is wanting to view what is being translated - they can see the start of the document before all of it has been translated. In cases where the whole XML input stream can take some time to generate, or is large (eg, is being progressively generated by scanning a large data warehouse), this improvement could be considerable. As well, it gives the user the chance to abort the process if what they are looking at isn't what they wanted, potentially saving resources and their time. One way we can achieve this now is to generate the start of the outer container "manually" (eg, for HTML: <HTML><TITLE>...</TITLE><BODY>), then process and emit the chunks progressively, end then generate the end of the outer container manually. Are there better ways in existence or planned? Kent Fitch Ph: +61 2 6276 6711 ITS CSIRO Canberra Australia kent.fitch@xxxxxxxxxxxx XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
