It's common for preprocessors to strip comments; the traditional C preprocessor did so, and so does the GNU C compiler working in preprocessor-only mode. > My XMLSource object acts as a > buffer, and the parser moves forward and back in that buffer (array type > syntax) while trying to identify what is next in the file. Why backward and forward? Pass through everything except a % or a <!--. If it's a %, collect the following Name and the ;, look it up, pass through the value. If it's a <!--, skip everything till -->. > The thing is, > "what is next" in this case may (almost everything) or may not (comments) > want PEReference expansion, so I have to be able to say, get me the > character at index x, with PERef's expanded or without. > > And I am writing this parser in my _free_ time!?
