You never know at compile time what documents you or may not encounter. Just because the spec says a SOAP request can't contain a processing instruction or a document type declaration doesn't mean one won't. In order to be a conformant XML parser, a parser must adhere to the minimum requirements of XML 1.0. It is not enough to work correctly for only some subset of well-formed XML 1.0 documents. -- +-----------------------+------------------------+-------------------+ | Elliotte Rusty Harold | elharo@m... | Writer/Programmer | +-----------------------+------------------------+-------------------+ | XML in a Nutshell, 2nd Edition (O'Reilly, 2002) | | http://www.cafeconleche.org/books/xian2/ | | http://www.amazon.com/exec/obidos/ISBN%3D0596002920/cafeaulaitA/ | +----------------------------------+---------------------------------+ | Read Cafe au Lait for Java News: http://www.cafeaulait.org/ | | Read Cafe con Leche for XML News: http://www.cafeconleche.org/ | +----------------------------------+---------------------------------+
