Yes, it seems that the code can use ' or " and only fallback to concat() if both types of quotes appear in the variable... > I was thinkin about something like > > selectNodesParametrized (node, "/element[@attr ='$$']", variableString); > >isn't that just > >select="/element[@attr = $variableString]" ? > >or perhaps I didn't understand the question. That might work in a stylesheet, but I don't think that the selectNodes() method in the MSXML DOM has any notion of variables... How could it?
