   Re: [xml-dev] DOCTYPE

[ Lists Home | Date Index | Thread Index ]

If you are asking if you can supply the DTD for a parser to use at runtime, then consult the
parser documentation. You may not even need to change any text, but just provide a
CATALOG file (to remap the declaration) or supply a command-line parameter.

If you are asking for an algoithm to let you safely insert a DOCTYPE declaration 
on the fly yourself, following is a quick stab. It should be good enough if you are just 
serializing elements. Start by assuming there is already no DOCTYPE declaration and 
that any PIs or comments don't have < in them.

  * Search for the first "<" not followed by "!", "?" or whitespace. 
  * If the next character is "/" then that is an end-tag and your document is not well-formed
  * Store the string on the current line until the first white space or ">" or "/" character.
     That is the first elements name.
  * Insert your DOCTYPE declaration with that string, immediately before that
     first "<" (*not* at the start of the file: this way you preserve any XML headers
     and stylesheet PIs)
  * Make each of the 4 examples below into XML documents, and test your routine
     on each of them. They each test some common edge cases.
