This is true, but hardly likely to be a useful technique. I don't think many stylesheets are likely to visit the same node more than once in the same mode, and the space cost of adding an extra object reference to each node in the tree (or worse, one object reference per mode) almost certainly exceeds the time benefit. Since most practical match patterns are very simple, pattern matching is not actually very time-consuming. Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
