在Moodle的Div中使用wiris显示方程式

Question

I am using wiris plugin for tinyMCE editor in Moodle. Using the wiris editor I type some equations. But these equations are inserted in database as

<p>«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«msup»«mi»x«/mi»«mn»4«/mn»«/msup»«/math»</p>

this format. And while display these in browser it display as same

<p>«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«msup»«mi»x«/mi»«mn»4«/mn»«/msup»«/math»</p>

But I have to display as:

How can I do this? Please help me..

EDIT

My problem is the equation generated using WIRIS is displaying in tinyMCE editor as desired, but while displaying in div/span/table etc it display as

<p>«math xmlns=¨http://www.w3.org/1998/Math/MathML¨»«msup»«mi»x«/mi»«mn»4«/mn»«/msup»«/math»</p>

Once enabled, our filter automatically converts safeXML to formula images in Moodle contexts without any additional logic. If you try creating a regular native Moodle question including a WIRIS formula and then preview it, using Moodle's default preview, the formula will show as an image.

If you are trying to display the formulas in a custom module you are building from scratch, the scenario is different. Are you filtering the content before displaying it? You need to use format_text() so that the filter parses the text you are displaying. Please check the code of /<moodle>/blocks/html/block_html.php and how format_text() is used. We also recommend that you check the Moodle filter documentation at https://docs.moodle.org/dev/Filters#A_note_about_performance
