How to exclude text from translation using /TranslateArray - microsoft-translator

Question

We're trying to use the Microsoft Translator API to batch translate text. Each piece of text may contain text we don't want translated (normally social network #handles or hashtags). We've tried to wrap these parts of the text like is shown in the documentation:
<div class="notranslate">This will not be translated.</div>
This works fine when passing text to the /Translate single API. However, when we pass multiple pieces of text to the /TranslateArray API, we can't work out the correct syntax. Any text item which contains the notranslate div is not returned in the response.
Here's the body we're trying to use:
curl -i -X POST \
-H "Ocp-Apim-Subscription-Key:******" \
-H "Content-Type:text/html" \
-d \
'<TranslateArrayRequest>
<AppId />
<From>en</From>
<Options>
<ContentType xmlns="http://schemas.datacontract.org/2004/07/Microsoft.MT.Web.Service.V2">text/html</ContentType>
</Options>
<Texts>
<div xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">With great power comes great <div class="notranslate">#responsibility</div> </div>
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">Hello World</string>
</Texts>
<To>fr</To>
</TranslateArrayRequest>' \
'https://api.microsofttranslator.com/V2/Http.svc/TranslateArray'
Any ideas on the correct format to pull this off?

Answer 1

The section as posted doesn't match the schema for the request: the first <div> needs to be a <string> element.
<Texts>
<div xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">With great power comes great <div class="notranslate">#responsibility</div> </div>
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">Hello World</string>
</Texts>
Try:
<Texts>
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">With great power comes great <div class="notranslate">#responsibility</div> </string>
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">Hello World</string>
</Texts>
If this doesn't work, then it's possible that because the request is XML, you may also need to XML-escape the markup within the string element:
<string xmlns="http://schemas.microsoft.com/2003/10/Serialization/Arrays">
With great power comes great <div class="notranslate">#responsibility</div>
</string>
