dr. van der Meer,
\xmldoifatt (with ifnot and ifelse variants) should cover that case
(https://www.pragma-ade.com/general/manuals/xml-mkiv.pdf#search=xmldoifatt).
But I cannot make any of these conditionals work (I‘m afraid there may
be an issue with their definition).
\startbuffer[ifdefined]
<document>
<macro name="bold" arg="text"/>
<macro name="hvdm" arg="text"/>
</document>
\stopbuffer
\startxmlsetups xml:hvdm
\xmlsetsetup{#1}{*}{xml:*}
\stopxmlsetups
\xmlregistersetup{xml:hvdm}
\startxmlsetups xml:document
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:macro
\xmlatt{#1}{name}\\
\xmlatt{#1}{arg}\\
\xmldoifelseatt{#1}
{name}{yes}{no}\\
\xmldoifelseatt{#1}
{names}{yes}{no}\\
\stopxmlsetups
\starttext
\xmlprocessbuffer{hvdm}{ifdefined}{}
\stoptext
As a workaround \doifelsetext{\xmlatt{#1}{name}}{yes}{no} may do the
trick here.
I hope it helps,
Pablo
