Hi,

I'm trying to check whether an attribute contains (or, actually starts with) a given string.
I've tried a whole bunch of different combinations, but I've had no luck so far. Minimal example below. Anyone has a hint?

Best,
Denis

\startxmlsetups xml:test
                \xmlsetsetup{#1}{*}{-}
                \xmlsetsetup{#1}{doc|element}{xml:*}
\stopxmlsetups

\xmlregisterdocumentsetup{test}{xml:test}


\startxmlsetups xml:doc
\xmlflush{#1}
\stopxmlsetups

\startxmlsetups xml:element
\xmlfilter{#1}{./find(attribute('class'), 'abc')/command(xml:whatever)}

\xmldoifelse{#1}{./attribute('class')/contains('abc')} {Yes}{No}
\stopxmlsetups

\startxmlsetups xml:whatever
Yes
\stopxmlsetups

\startbuffer[test]
<?xml version="1.0" encoding="UTF-8"?>
<doc>
<element class="abcdefg">Yes</element>
<element>No</element>
</doc>
\stopbuffer

\starttext

\xmlprocessbuffer{test}{test}{}

\stoptext
