| scottp 09:17 Apr 11, 2008 | I'm unable to load a document tree that contains internally defined entities. I've included a simple file below that refuses to load for me. Internal (parsed) entities are quite common in the publishing world and are definitely part of the core XML spec .. http://www.w3.org/TR/2004/REC-xml-20040204/#sec-internal-ent Thanks! ...scott ---------------------------------------------------- <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE topic PUBLIC "-//OASIS//DTD DITA Composite//EN" "ditabase.dtd" [ <!ENTITY myent "TEST"> ]> <topic id = "id0844H000R5Z" > <title>dita</title> <body> <p>dita file <ph>&myent;</ph></p> </body> </topic> --------------------------------------------------- |
| scottp 14:35 Apr 24, 2008 | Ah .. I see that it's not the definition of the internal entities that's causing the trouble, it's the actual use of those entities. And I see in the docs that minixml does not support entities other than those required by the XML spec. This is a real problem for me since the documents that I'm parsing may have internal entities or entities defined in a DTD. Is there some way to just have the parser skip over the entities? |
| Michael Sweet 11:44 Oct 26, 2008 | OK, I've reviewed the spec, and the current Mini-XML API cannot be extended to support internal (or external) entities without breaking binary compatibility. Aside from needing to support multi-character substitution (the current API only supports substitution of single Unicode characters), it would be better to track the entities within a document rather than having a global (to the current thread) scope. In any case, I don't know whether this will be implemented any time soon (or if it is ever implemented), since Mini-XML isn't designed as a validating XML parser that can import/interpret processing directives. |
