Yes, but the question was: how do I code this in the XML and get it through my
XML-lua-METAPOST-textext() path so that e.g. or in the XML end up
as \ in my textext() string?
E.g. a in XML becomes a \n when lmtx XML handling has read the XML (so
gets transformed on read). I’ve been thinking about the route -> \r -> \
(so, misusing \r to code a TeX-\ in the XML, but that would probably not robust.
The question is more: what is a good UTF8 character to use (the first 32 would
be good candidates if they would work and end in the strings that xml.foo() of
lmtx produces).

I tried \crlf{} and that worked too (the “{}” because I do not know what comes
after even if I think any whitespace is eaten and to influence any catcode
trickery, just feels it is more robust than a space).
Hans, an additional question about lmtx’s XML interface. As I want the TeX
special characters to be able to be part of a label, I replace all of them.
That works. But what if I would like a way to introduce TeX commands again by
using some other UTF8 character, would there be a character that curvies the
pass through lmtx, can be used in a lua table so that I can (in a preferred
order) get unescaped characters passed that flow?
E.g. code a \ as some weird UTF8 character in the XML file, and in that table I
use
local rep = lpeg.replacer {
{ '\n', '\\crlf{}' },
{ '{', '{\\textbraceleft}' },
{ '}', '{\\textbraceright}' },
{ '#', '{\\texthash}' },
{ '$', '{\\textdollar}' },
{ '&', '{\\textampersand}' },
{ '%', '{\\textpercent}' },
{ '\\','{\\textbackslash}' },
{ '|', '{\\textbar}' },
{ '_', '{\\textunderscore}' },
{ '~', '{\\textasciitilde}' },
{ '^', '{\\textasciicircum}' },
{ '"', "\"&\"" },
}
code it back to a \ ? E.g. something like
{ ‘\U{XXX}', '\' },

you could try
\xmltexentity{foo}{[overloaded foo]}

did you try the attached approach? (a recent lmtx)

Too happy too soon. And I recall I ran into this earlier a while ago in another
setting ago. But I thought of a solution.
Background:
I am automatically converting input from an XML file to METAPOST/ConTeXt. The
input may contain one or more newlines.The text must end up in
\framed[align=??, width=??] to be typeset.
I use lua to convert and make it safe to pass to METAPOST as a string argument
that METAPOST can pass on to textext(), using the following function:
function doubleQuotableEscapedConTeXtString( str)
local rep = lpeg.replacer {
{ '\n', '\\blank ' },
{ '{', '{\\textbraceleft}' },
{ '}', '{\\textbraceright}' },
{ '#', '{\\texthash}' },
{ '$', '{\\textdollar}' },
{ '&', '{\\textampersand}' },
{ '%', '{\\textpercent}' },
{ '\\','{\\textbackslash}' },
{ '|', '{\\textbar}' },
{ '_', '{\\textunderscore}' },
{ '~', '{\\textasciitilde}' },
{ '^', '{\\textasciicircum}' },
{ '"', "\"&\"" },
}
return rep:match(str)
end
Where it now says \\blank, it used to say .
Problem
gets me what I want if there is one \n (it turns into one new line), but
with two \n in succession it still gets me only a single ’newline'
\\blank gets me what I want if there are multiple newlines, but gets me an
extra empty line when I only want ’next line’ and multiple \blanks do not work
But I found the solution by using \strut\\ instead of \blank. In the above
table:
{ ‘\n', ‘\\strut' },
This fools ConTeXt in thinking there actually is something on that line and so
multiple \\ will work.

I did set the align option to get a vbox.

Try \framedtext instead; multi line text needs a \vbox, and \framedtext does
that. (If I understood correctly.)
Maybe you need to set the align option.
