Proper Display of XML Equations in HTML

This article explains how to make sure display equations appear correctly when your article XML is converted to HTML on a JAMS-hosted website.

When this happens

Sometimes a display equation (an equation that sits on its own line and is usually numbered) does not render correctly in the published HTML on a hosted website. This normally happens when the equation has not been wrapped in the correct XML tags during conversion.

The fix

Wrap each display equation in a <disp-formula>   element, and give it an equation number using a <label>   element. For example:

<disp-formula>content<label>(1)</label></disp-formula>

• <disp-formula>   marks this as a display (block) equation, so it appears on its own line rather than inline with the text.
• Replace content   with the equation itself.
• <label>(1)</label>   sets the equation number shown alongside it. Increase the number for each new equation, so (1), (2), (3), and so on.

Where to apply this

This change is made in the article XML, which is handled during the conversion stage.

If equations still do not display

If a display equation still appears incorrectly after you have applied the tags above, contact the JAMS team so they can check the conversion for you. You can get in touch through the Communication with Conversion Editors page.
