BatchJobService upload containing objects with "&" can't be serialized

[geropeter]

I have an XML product feed, which I was trying to process with BatchJobService, but in many cases an exception was thrown, saying "unterminated entity reference". This happened before the objects were uploaded to AdWords, so I took a look at the XmlSerializer utility, because I traced back the issue to ConvertObjectToElement method, line 83:

$element->nodeValue = self::ConvertObjectToNodeValue($object);

This assigning failes in case of an object wich has attributes containing the '&' character. I have used htmlspecialchars($string, ENT_XML1, 'UTF-8') on those fields, so the exception is not thrown anymore.

Shouldn't this be handled by the util class?

Will look into this. Thanks for reporting.
