I'm not sure what this is, so sure go ahead...! :-) I'm currently operating with string, and decoding UTF-8 into ISO8859-1, and throwing away everything that doesn't fit. This works for now, because Latin 1 in UTF-8 is all we ever dump. We'll move to wstring throughout our system later on.

When I replaced my const string&-returning AttributeList, with one where the caller has to supply the string to copy into, I came out the same (except this one works...:-) ) But then I iterate through all attributes of an element and fill the result into variables, that have a default and are sent to a callback. I don't ask for attributes by name. > I prefer the approach we've taken although you cant tell the > difference between not present and empty string. > The same feedback has come from our customers who were involved last year > when putting together the original include files together. > I guess at the end of the day you have to find a comprimise between > usability and pureness. The good thing about my string as argument alternative is the possibility for minimizing string copies. I can UTF-8 decode directly into the string I use all the way into callback class arguments (ie. one copy may be enough). xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
