Hi everyone. I would like to be able to look through a RelaxNG schema to see if a given element type is surrounded by <oneOrMore> or <zeroOrMore>, to know whether more than one of those elements is allowed. This would be easy to do, except that the schema has several <ref>s and <define> groups.
I believe that internally the parser must replace each <ref> literal with the data of its corresponding <define> group (i.e. inline the group) in order to create a single cohesive schema that the validator can use. However, I cannot find a way to dump this post-processed inlined schema to a file so I can search through it. I tried this in python: outfile = open(sys.argv[2], "w") outfile2 = open(sys.argv[3], "w") ctxt = libxml2.relaxNGNewParserCtxt(sys.argv[1]) schema = ctxt.relaxNGParse() schema.relaxNGDumpTree(outfile) schema.relaxNGDump(outfile2) where sys.argv[1] is the name of the schema file itself. outfile basically contains the input file contents. The <ref>s are still intact; the data of the referenced <define> is not substituted inline. outfile2 contains only this: RelaxNG: manifest.rng <grammar xmlns="http://relaxng.org/ns/structure/1.0";> <start> </start> </grammar> The call to relaxNGDump() gives this message: Unimplemented block at relaxng.c:7672 I've made sure to test with the latest library as well: I ran with the library created from release 2.6.32. xmllint --version shows this: xmllint: using libxml version 20632 compiled with: Threads Tree Output Push Reader Patterns Writer SAXv1 FTP HTTP DTDValid HTML Legacy C14N Catalog XPath XPointer XInclude Iconv ISO8859X Unicode Regexps Automata Expr Schemas Schematron Modules Debug I've searched the archives but there aren't really good keywords to use. (I tried schema, inline and define) What do I need to do to dump out a schema which has inlined the data of each referenced <define>? Thanks, Jack P.S. I am building an XML file layering mechanism and need this information to know whether to add or overlay new elements at a particular place in a DOM tree. _______________________________________________ xml mailing list, project page http://xmlsoft.org/ [email protected] http://mail.gnome.org/mailman/listinfo/xml
