Can you sketch an algorithm that will convert SGML-style (or &-less SGML-style) content models involving #PCDATA into content models involving #PCDATA and #WS, where #WS is a data type that matches only white space, such that random white space around tags will be properly accounted for? Remember that XML parsers are required to pass along all whitespace, (i.e. it all appears in the infoset, barring whitespace outside the root element), so it needs to be accounted for somehow, when it is #PCDATA and when it isn't. -- John Cowan http://www.ccil.org/~cowan cowan@c...
