Hi,
I have an XML file (which is generated via a program that I have no
control over), which contains elements as follows:
<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>
I want to typeset the `text` attribute of equation (and ignore the <img>
tag). So, I tried:
\startxmlsetups matlab
% Bunch of missing definitions
\xmlsetsetup{#1}{equation}{matlab:*}
\stopxmlsetups
\startxmlsetups matlab:equation
\xmlatt{#1}{text}
\stopxmlsetups
This literally typesets `$$y_1(t) = 1, t \geq 0$$`. How can I flush the
attribute using ctxcatcodes? (There is \xmlflushcontent, but that is for
content and not attributes).
Time for an "aha, I knew it" moment ...
\starttext
\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 whatever
\xmlsetsetup{#1}{p|equation}{xml:*}
\stopxmlsetups
\xmlregistersetup{whatever}
\startxmlsetups xml:p
\xmlflush{#1}
\stopxmlsetups
\startxmlsetups xml:equation
\cldcontext{lxml.getid("#1").at.text}
\stopxmlsetups
\startxmlsetups xml:equation
\startformula
\cldcontext{(string.gsub(lxml.getid("#1").at.text,"[$][$]",""))}
\stopformula
\stopxmlsetups
\xmlprocessbuffer{main}{test}{}
\stoptext
