Subject: Re: [xsl] Query regarding validating XML with DTD From: "Eric Bréchemier" <eric.brechemier@xxxxxxxxx> Date: Thu, 27 Sep 2007 11:56:27 +0200 |
Hello Deepak, you (and your application) should not assume that data produced will always be valid. The DTD is like a contract between you and the data producer, that allows to check whether the received item matches the specification. You should definitely activate validation by default in production, and I would even advise using stronger validation than DTD alone can provide like XML Schema or RELAXNG. For performance purpose, you could try to optimize the validation by compiling the schema and keeping a pool of instances of the validator alive.
