How To Simply Push A Variable To An HtmlService Template AS Html

I am using:

var template = HtmlService.createTemplateFromFile("MyForm.html");

Which contains a variable:

<?= defaultInnerHtml ?>

And I am trying to assign THIS variable with the content of another HTML file:

template.defaultInnerHtml
    = HtmlService.createHtmlOutputFromFile(
        "MyInnerHtml.html").getContent();

But the contents of MyInnerHtml.html become encoded: the angle brackets are replaced with entities etc. I am trying just to stuff some more Html inside the MyForm.html file before serving that back.

I can't see how to get just the raw contents to show up in place of the variable in the template.

Any help?

To disable this contextual escaping of special characters, change your template so it embeds the value of the variable like this:

<?!= defaultInnerHtml ?>

Note the exclamation mark. This specifies force-printing, which directs the template engine to embed the contents of the variable verbatim.

From Google's documentation:

Contextual escaping is important if your script allows untrusted user input. By contrast, you’ll need to force-print if your scriptlet’s output intentionally contains HTML or scripts that you want to insert exactly as specified.
