Re: [NTG-context] problem with character entities in XML processing

19 Apr 2018

      Indeed. I should have known better. Temporary attack of brain weakness, I suppose. For those who want to see for themselves, the minimal example below will do.

dr. Hans van der Meer

% test character entity.
\startxmlsetups demo:entity
	\xmlsetsetup{#1}{root}{demo:entity:*}
\stopxmlsetups
\xmlregisterdocumentsetup{demo}{demo:entity}
\startxmlsetups demo:entity:root
	\blank Start test:\crlf
	flushing: \xmlflush{#1}\crlf
	End test\blank
\stopxmlsetups
\startbuffer[demo]
<?xml version="1.0" encoding="UTF-8"?>
<root>amp = & and #38 = &</root>
\stopbuffer
\starttext
\currentdate-\currenttime\quad\ConTeXt-version=\contextversion\blank
{\bf Testing use of character entities}\blank
These should produce the same result: \type{&} and \type{&} and indeed they do.\blank
\xmlprocessbuffer{demo}{demo}{}\blank
\stoptext
...

The following use of character entities & aborts in ConTeXt. That is of course because the # is seen as a parameter. Changing this to &\#xxx; or &\letterhash xxx; typesets & as is, but that is not the intention, because an ampersand should appear. So, how do I proceed here?
Minimal example:
% test character entity failure.
\startxmlsetups demo:entity
\xmlsetsetup{#1}{root}{demo:entity:*}
\stopxmlsetups
\xmlregisterdocumentsetup{demo}{demo:entity}
\startxmlsetups demo:entity:root
\blank Start test:\crlf
root: <amp> = "&"\crlf
root: <number> = "&\letterhash 038;”\crlf % &\#038; produces the same
End test\blank
\stopxmlsetups
you are tex mode there so & == &
...
\startbuffer[demo]
<root></root>
\stopbuffer
\starttext
\currentdate-\currenttime\quad\ConTeXt-version=\contextversion\blank
{\bf Testing use of character entities}\blank
These should produce the same result: \type{&} and \type{&}\blank
\xmlprocessbuffer{demo}{demo}{}\blank
\stoptext
