Hi Michael,

The plugin is Javascript based:

https://github.com/oxygenxml/wsaccess-javascript-sample-plugins/blob/master/latex-images-support/wsAccess.js<https://urldefense.com/v3/__https:/github.com/oxygenxml/wsaccess-javascript-sample-plugins/blob/master/latex-images-support/wsAccess.js__;!!BpyFHLRN4TMTrA!tD_JomHTrO0SM9nkqJ8Jjr9aSSeDGc4aiO850hbJdt-kqE84UdmgyTxQY14w-QYxF1Lg$>

and has this condition to identify XML elements that it should render:
return "latex" == nodeContext.getNodeName() || ("foreign" == nodeContext.getNodeName() && "embed-latex" == nodeContext.getAttributeValue("outputclass"));
I think in your case the condition should be:
return "tex-math" == nodeContext.getNodeName() && "MathJax" == nodeContext.getAttributeValue("version");
You probably also need to modify the CSS Oxygen uses to edit JATS content to hide the text content from the element, probably something like:
tex-math[version=MathJax]{
    display:inline !important;
    white-space: -oxy-trim-when-ws-only !important;
}
tex-math[version=MathJax] * {
    display:none !important;
    white-space:normal !important;
}


Regards,

Radu

Hello,

The blog post at https://blog.oxygenxml.com/topics/adding-latex-equation-support-dita.html<https://urldefense.com/v3/__https:/blog.oxygenxml.com/topics/adding-latex-equation-support-dita.html__;!!BpyFHLRN4TMTrA!tD_JomHTrO0SM9nkqJ8Jjr9aSSeDGc4aiO850hbJdt-kqE84UdmgyTxQY14w-TLmHLWz$> refers to a plugin that will create an image from LaTeX to display in Author mode.

I downloaded the ‘latex-images-support’ folder and installed it in my plugins folder. The math expression in the sample file—


<?xml-stylesheet type="text/css" href="sample.css"?>
<root>
    A document containing LaTeX :
    <latex>$x=\frac{1+y}{1+2z^2}$</latex>
</root>

is rendered correctly as an image when I view it in Author mode (using Oxygen 23.0).

I’d like to be able to use the plugin with JATS XML documents, which can contain LaTeX inside a <tex-math> element, like so:

<tex-math notation="LaTeX" version="MathJax">$x=\frac{1+y}{1+2z^2}$</tex-math>
or

<tex-math notation="LaTeX" version="MathJax"><![CDATA[$x=\frac{1+y}{1+2z^2}$]]></tex-math>



Is there a way to configure or modify the plugin to handle this?
