Using Lua gsub(), I need to replace something like:
string.gsub([[\xmlraw{#1}{.}]], "%", "\\letterpercent")
Double it: %%
See also https://www.lua.org/manual/5.3/manual.html#6.4.1 , but the
mention of %% is a bit hidden.
Many thanks for your replies, Taco and Hans.
I’m afraid this doesn’t work (and I need \xmlraw there):
\startbuffer[demo]
<html>
<body>
<div id="First">
<p>The <span class="special">% best</span> paragraph.</p>
</div>
</body>
</html>
\stopbuffer
\startxmlsetups xml:initialize
\xmlsetsetup{#1}{html}{xml:gen}
\stopxmlsetups
\xmlregistersetup{xml:initialize}
\startxmlsetups xml:gen
\startitemize
\xmlfilter{#1}{/**/span[@class='special']/command(xml:special)}
\stopitemize
\stopxmlsetups
\startxmlsetups xml:special
\startitem
\cldcontext{string.gsub([[\xmlraw{#1}{.}]], "%%",
"\\letterpercent")}
\stopitem
\stopxmlsetups
This works fine with your example
\startxmlsetups xml:special
\startitem
\xmlflush{#1}
\stopitem
\stopxmlsetups
and to escape special characters you can use context.escape()
\startxmlsetups xml:special
\startitem
\cldcontext{context.escape([[\xmlraw{#1}{.}]])}
\stopitem
\stopxmlsetups
