Help with XmlPullParserException

[Phillip Farber]

Hello all,

I'm indexing a body of OCR and encountered this exception. Apparently 
it's some kind of XML parser error.  Out of thousands of documents, 
which I create with significant processing to make sure they are XML 
compliant, only this one appears to have a problem.  But can anyone tell 
me what this specific error message means?


SEVERE: org.xmlpull.v1.XmlPullParserException: character reference (with 
decimal value) may not contain a (position: START_TAG seen ...dieses aus 
dem \nZusammenbestehen der Gleichungen \n\naajj2 -)- 2&#1a... @21781:16)


Thanks!

Phil
