XML Parsing Error: not well-formed Location

When the below comparison will throw an exception when being displayed in fireunit using pretty print (actual test works fine and succeeds).

fireunit.compare('<test>', '<test>', 'comparing bracketed values');

Error:

XML Parsing Error: not well-formed Location: moz-nullprincipal:{99b4e839-a0cc-448e-a0ef-23eccd873513} Line Number 1, Column 24:

<test>

In fireunit.js:insertXml is generating invalid XML on this line when result.expected has something that is not valid as a XML element body. I'm not sure if there is a valid case for treating the expected result as actual XML nodes itself but it would be possible to get rid of this error by wrapping the contents of with <[CDATA[]]>

var tempXml = "<wrapper>" + xml + "</wrapper>";
