All too often the terms "infoset" or "grove" are thrown about in a way that suggests some incomprehensible complexity. In day to day practice, and particularly for a "simple guy with a simple problem" I say this: You have posed the wrong problem! Who cares if the document is identical? SAX (or DOM or XPath or JDOM etc etc etc) provides an interface to handle processing of your document. When using one of these common interfaces a bunch of irrelevent information is thrown out. The "infoset" is just a fancy term that says what information is relevent and what is irrelevent. Basically this says that if you can't get the information from a SAX or DOM interface then forget about it (remember you are a simple guy with a simple problem). > I am championing the complete separation of DTD and > instance as a first step towards exploring an alternative, > layered approach to this sort of processing which makes > a parsing based paradigm workable whilst leaving > the unaffected parts of a document "the same" en route to > further processing stages. > Firstly simple guys with simple problems _don't_ use internal subsets. Just because your toolset includes a fancy wrench doesn't mean that you ought use it for tightening a simple nut. My advice is to put that wrench away for a day in which your simple wrench doesn't work -- but don't throw it away because the day you need it, you'll be glad its in your toolbox. -Jonathan
