& cannot occur by itself in a XML document as it is used to start a XML entity reference. Therefore, your XML document must contain &amp; and not & if a parser has to parse its contents correctly and return & in the text content. & is not the only character that XML parsers will fail to parse incorrectly if they are present on their own; there are other characters that must be present as the predefined XML entities for parsing to occur correctly.

You should either correct the document, by using entity references or use CDATA sections to transport the special characters in the payload.
