Hello,
I am currently trying to find a solution as how to ignore DOCTYPE elements when parsing XSD files with the loadGrammar function. I only want to ignore DOCTYPE elements while parsing, but not <include> elements that may reference other nested schema files I want as part of the overall Grammar. Buried in any of these nested schemas could potentially be DOCTYPE elements that should ignored as well. My last requirement in this is that I use a DOM parser. Below is a subset of some things Ive already tried and had no success with: * Set load external DTD to false and Validation to Never prior to loadGrammar call. * Set Skip DTD validation to true and Validation to Always prior to loadGrammar call. * Set create entity reference nodes to false (disregards all DOCTYPES and include elements) and does not build grammar properly. * Created custom entity resolver to return NULL when encountering elements that match DTD files, and set parser to disable default entity resolution process during parse * Attempted all of the above with against both DOM parsers (DOMLSParser and the XercesDOMParser) My test is relatively simple. 1. Create parser 2. Configure parser 3. Pre-load parent schema into grammar pool 4. Configure parser to validate always 5. Parse a XML file that validates against the schema with no errors thrown during parse operation The offending file in my specific case is the xml.xsd (https://www.w3.org/2004/10/xml.xsd) provided by W3C. That file has XMLSchema.dtd referenced in a DOCTYPE in the 2nd line. Since this defines the elements attributes of standard XML, if you set it to NULL in a custom entity resolver, the Xerces parser will not be able to understand basic XML element attributes like xmlns. Curiously, if you comment out the aforementioned DOCTYPE line in the schema, the Xerces parser is able to fully parse the grammar without issue. Am I being naïve as how the Xerces parsers are designed to work? Is there an obvious solution to this situation that does not involve editing the schema files to remove the DOCTYPE elements? Thank you very much for your time, Dave Schloss
