You could write your own attribute fetcher in Lua. Probably there is a
more elegant method.
\startbuffer[test]
<p>
<equation text="$$y_1(t) = 1, t \geq 0$$">
<img alt="$$y_1(t) = 1, t \geq 0$$" class="equation"
height="15px" src="Lab01_eq10401623798909303081.png" width="95px"/>
</equation>
</p>
\stopbuffer
\startxmlsetups matlab
% Bunch of missing definitions
\xmlsetsetup{#1}{p}{matlab:*}
\xmlsetsetup{#1}{equation}{matlab:*}
\stopxmlsetups
\startxmlsetups matlab:p
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups matlab:equation
\xmlfunction{#1}{equation}
\stopxmlsetups
\startluacode
local a = "text"
local ctxcatcodes = catcodes.numbers.ctxcatcodes
function xml.functions.equation(id)
local e = lxml.getid(id)
if e then
local at = e.at
if at then
local att = at[a]
if att ~= "" then
context.sprint(ctxcatcodes,att)
end
end
end
end
\stopluacode
\xmlregistersetup{matlab}
\starttext
\xmlprocessbuffer{test}{test}{}
\stoptext
