Aah yes, how silly of me to forget to add \starttext... \stoptext! Thanks for your help.

Dear List,

In my continuing effort to improve my ConTeXt skills I thought I would have a look at XML and ConTeXt. Note: I have no XML skills but, "in for a penny, in for a pound", as they say over here. I started by looking at the very first example on page 5 of "Dealing with XML in ConTeXt mkiv" and straight away hit a problem.  There is a typo in the first line of the XML file which I corrected:

<?xml version='1.0' standalone='yes?>

should be

<?xml version="1.0" standalone="yes"?>

However when I ran the file using the tex file it only produced a 3 page pdf with a contents page and 2 title pages and no other text.

Here is the XML file which is the similar to the one on page 5 but with two sections rather than one:

<?xml version="1.0" standalone="yes"?>

<document>

<section>

<title>Some title</title>

<content>

<p>a paragraph of text</p>

<p>another paragraph of text</p>

</content>

</section>

<section>

<title>Another title</title>

<content>

<p>a paragraph of text</p>

<p>another paragraph of text</p>

</content>

</section>

</document>

The TeX file is cut and pasted from pages 5 and 6 of xml-mkiv.pdf:

\startxmlsetups xml:demo:base

\xmlsetsetup{#1}{document|section|p|itemize|item}{xml:demo:*}

\stopxmlsetups

\xmlregisterdocumentsetup{demo}{xml:demo:base}

\startxmlsetups xml:demo:document

\starttitle[title={Contents}]

\placelist[chapter]

\stoptitle

\xmlflush{#1}

\stopxmlsetups

\startxmlsetups xml:demo:section

\startchapter[title=\xmlfirst{#1}{/title}]

\xmlfirst{#1}{/content}

\stopchapter

\stopxmlsetups

\startxmlsetups xml:demo:p

\xmlflush{#1}\endgraf

\stopxmlsetups

\xmlprocessfile{demo}{demo.xml}{}

This seemed such a simple example and I'm a bit perplexed as to why it did not work. Can somebody explain why no paragraphs are showing up? I'm using:

ConTeXt ver: 2018.04.04 00:51 MKIV beta fmt: 2018.6.2 int: english/english

LuaTeX, Version 1.07.0 (TeX Live 2018)

Thanks and Best Wishes

you need to add \starttext ... \stoptext

\startbuffer[demo]
<?xml version="1.0" standalone="yes"?>

<document>
    <section>
        <title>Some title</title>
        <content>
            <p>a paragraph of text</p>
            <p>another paragraph of text</p>
        </content>
    </section>
    <section>
        <title>Another title</title>
        <content>
            <p>a paragraph of text</p>
            <p>another paragraph of text</p>
        </content>
    </section>
</document>
\stopbuffer

\startxmlsetups xml:demo:base
    \xmlsetsetup{#1}{document|section|p|itemize|item}{xml:demo:*}
\stopxmlsetups

\xmlregisterdocumentsetup{demo}{xml:demo:base}

\startxmlsetups xml:demo:document
    \starttitle[title={Contents}]
        \placelist[chapter]
    \stoptitle
    \xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:demo:section
    \startchapter[title=\xmlfirst{#1}{/title}]
        \xmlfirst{#1}{/content}
    \stopchapter
\stopxmlsetups

\startxmlsetups xml:demo:p
    \xmlflush{#1}\endgraf
\stopxmlsetups

\starttext
    \xmlprocessbuffer{demo}{demo}{}
\stoptext
