You're right! Say that you have:
\unprotect
\def\@@XMLescape {\@@XML esc}
\def\defineXMLescape[#1]#2{\long\setvalue{\@@XMLescape:#1}{#2}}
\defineXMLescape [--] {\gobbleuntil{-->}}
\defineXMLescape [CDATA] {\skipfirstverbatimlinefalse
\processtaggeddisplayverbatim{]]>}}
\defineXMLescape [\s!default] {\gobbleuntil{>}}
\def\executeXMLescape#1%
{\executeifdefined{\@@XMLescape:#1}{\getvalue{\@@XMLescape:\s!default}}}
\protect
\long\def\xdoXMLelement !#1 % !-- --> or !xyz >
{\endgroup\executeXMLescape{#1}}
Now, given that you have a </hello/> <world/> file, and a ! handler like:
\defineXMLescape [DOCTYPE] {\handleXMLescapeDOCTYPE}
\defineXMLescape [ENTITY] {\handleXMLescapeENTITY}
\def\handleXMLescapeDOCTYPE#1[#2]>%
{#2}
\def\handleXMLescapeENTITY#1 #2 "#3"#4>%
{\doif{#2}{SYSTEM}{\defineXMLentity[#1]{\readfile{#3}{}{}}}}
then:
\defineXMLsingular [test] {WHOW}
\defineXMLsingular [hello] {Hello}
\defineXMLsingular [world] {World}
\startXMLdata
<!DOCTYPE some unreadable crap
[ <!ENTITY wellwell SYSTEM "test.xml"> ]>
test <test/>
<!-- hellup -->
test <test/>
&wellwell;
\stopXMLdata
will do what you want. But i suppose that the DOCTYPE syntax is richer that
this example and i praise myself lucky that i don;t have a copy of the
specs here -)
