All the contributors to this thread so far seem to have concentrated on the difficulties posed by recognising the _end_ of a CDATA content - while checking for a matching GI adds complexity, it is not impossible. But one thing that *is* impossible is for a non-validating parser to know that '<' followed by a name token is to be read as data, rather than as a start-tag. You need to read the DTD to know the content is CDATA. (Okay, you could use the rmd parameter of the XML declaration, but encouraging authors to do this would remove some of XML's advantages. One in particular being the ability to parse much of the document while fetching the external subset) -----BEGIN PGP SIGNATURE----- Version: 2.6.3i Charset: noconv Comment: Processed by Mailcrypt 3.4, an Emacs/PGP interface iQB1AwUBNEtC5+dsuUurvcRtAQGu2AL+Jy+9Ja51J9X+tC1ghlvA9IvGvHvAelJu K42v2erQ12ErzQ6Z3G1XFgqA0FuVHUIEPtLmySlhyqpaLFVaGavQxNUG8V23QfC6 TgvNRKwbzDbMJBRL06rHrp9ewjHgZz0o =u7Sg -----END PGP SIGNATURE----- -- xml-dev: A list for W3C XML Developers.
