How to create any code from google spreadsheet like {.label} by Craft CMS ex) original HTML source code

&lt;link rel="exhibit/data" type="application/jsonp" href="https://spreadsheets.google.com/feeds/list/~~~~/od6/public/basic?alt=json-in-script" ex:converter="googleSpreadsheets" /&gt;


~~~~~

&lt;td valign="top" padding="0.5em"&gt;
    &lt;span style="text-alight:left;" ex:content=".label"&gt;&lt;/span&gt;&lt;br /&gt;
    &lt;b&gt;Aired: &lt;/b&gt;&lt;span ex:content=".start"&gt;&lt;/span&gt;&lt;br /&gt;
    &lt;b&gt;Genre: &lt;/b&gt;&lt;span ex:content=".genre"&gt;&lt;/span&gt;&lt;br /&gt;
&lt;/td&gt;


You can see .label, .start, and .genrem but on Craft CMS they are errors.

How do I create code with no errors?

Error message is,

Internal Server Error

Unexpected token "punctuation" of value ".".

*The error message displays like this on my PC's XAMPP
craft/templates/index,html


Thanks in advance!

ref image on google spreadsheet,
You need to use valid html/twig in your templates. Your “HTML Source Code” is not valid html. Removing the . from the beginning of your attributes i.e.: &lt;span ex:content="genre"&gt; should resolve the error, but it still wont be good html.

Best option, IMHO, is to start with a good solid foundation of valid html and work up from there.
