I was just about to ask the same! I agree that \xmltexentity ought to have precedence. I have an example: Which for some reason is being rendered as U+FFFD REPLACEMENT CHARACTER (a question-mark in a diamond). I don't know why that comes out as U+FFFD actually, since if I type a literal non-breaking space character instead, the PDF comes out just as if I'd used ~ in TeX. Maybe that's a bug somewhere? In any case, I think that sometimes it is helpful to override entities specifically for TeX processing, which aren't relevant for processing the XML source in other ways. -- Kate ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

The latter includes: > > Reference ::= EntityRef | CharRef > EntityRef::='&' Name ';' Sorry, I pointed to an outdated version of the XML 1.0 spec there. The current version (fifth revision) has the grammar written slightly differently, but still permits both well-formed ... tags and entities inside entity declarations: https://www.w3.org/TR/xml/#sec-entity-decl [70]EntityDecl ::= GEDecl | PEDecl [72]PEDecl ::= '' [74]PEDef ::= EntityValue | ExternalID [9] EntityValue ::= '"' ([^%&"] | PEReference | Reference)* '"' | "'" ([^%&'] | PEReference | Reference)* "'" [67]Reference ::= EntityRef | CharRef [68]EntityRef ::= '&' Name ';' Thus is permitted by productions applying ultimately to EntityRef, and ... is permitted by productions applying through the * closure of EntityValue's [^%&"] text (where [^...] means "not"). > Per this, all my examples are correct. > > O'Reilly XML in a Nutshell has an example: > http://docstore.mik.ua/orelly/xml/xmlnut/ch03_04.htm > > >> of course we can consider an option to parse the entity as xml >> >> (we can consider < as a trigger for parsing thereby kin dof automatically >> adapting) >> > > I do not think this is a good idea - per the XML spec, these entities > should always be taken as well-formed fragments

The usual case would be that there are no user-specified \xmltexentity definitions present at all, and the document's DTD entities would be used (by the feature you just added). So if somebody does have their own \xmltexentity specified, it's because they want that to be used instead. That would allow a user to do something specific for ConTeXt processing, but I don't have a good example for that. Personally I hope I can delete all my \xmltexentity calls now. -- Kate ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

So if somebody does have their own \xmltexentity specified, it's because they want that to be used instead. That would allow a user to do something specific for ConTeXt processing, but I don't have a good example for that. Personally I hope I can delete all my \xmltexentity calls now. of course that assumes that you don't need to revert to tex for rendering them Hans - Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.com | www.pragma-pod.nl - ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

But many DTDs contain definitions for entities, which I would like to use, rather than repeating those definitions by \xmlsetentity in ConTeXt. Some XML documents also have their own document-specific entities inside the DOCTYPE at the top of the file. For example in legal agreements, I have something like: ]> Where the stuff inside [...] is considered part of a document-specific DTD. libxml2 handles this sort of thing with its "dtdattr" options; I presume lxml has something similar. > >> a.xml: >> >> xxxyyyzzz >> >> a.tex: >> \startxmlsetups xml:mysetups >> \xmlsetsetup{\xmldocument}{a}{xml:*} >> \stopxmlsetups >> \xmlregistersetup{xml:mysetups} >> >> \startxmlsetups xml:a >> \xmlflush{#1} >> \stopxmlsetups > > > \enabledirectives[lxml.escapedentities] > \xmltexentity{nbsp}{~} > \xmltexentity{thinsp}{\thinspace} So that's how to use \xmltexentity! I had seen that, but couldn't find how to use it.
