Re: nbsp in XML (S01E01)

[mf <massifr@fastwebnet.it>]

Try this:

%\xmltexentity{nbsp}{\nobreakspace}

\xmlsetentity{nbsp}{ } % U+00A0 NBSP between braces

%\xmlsetentity{nbsp}{ } % U+0020 normal space between braces



\startbuffer[doc]

<?xml version "1.0"?>

<document>

         <p>Temperature 20 °C 20 °C 20 °C 20 °C average.</p>

         <p>Altitude 6000&nbsp;m 6000&nbsp;m 6000&nbsp;m 6000&nbsp;m 
average.</p>

</document>

\stopbuffer



\startluacode

--[[

function lxml.preprocessor(data)

     -- data = string.gsub(data, "&nbsp;", "~")

     -- replacement nbsp invisible in luacode

     data = string.gsub(data, "&nbsp;", " ")

     return data

end

--]]

\stopluacode





\startxmlsetups xml:name

     \xmlsetsetup{\xmldocument}{*}{-}

     \xmlsetsetup{\xmldocument}{document|p}{xml:name:*}

\stopxmlsetups

\xmlregistersetup{xml:name}



\startxmlsetups xml:name:document

\xmlflush{#1}\par

\stopxmlsetups



\startxmlsetups xml:name:p

\parfillskip0pt\xmlflush{#1}\par

\stopxmlsetups



\startTEXpage[offset=5mm,width=60mm]

\xmlprocessbuffer{xml:name}{doc}{}

\stopTEXpage
