Looks like you have an entity with invalid characters in your XML. How does the XML look like at the location the error message states?

Had to use strict: false and normalizeTags: true, and everything worked fine. besides the xmlns arrtributes are appearing in Uppercase didn't expect that.

[chetan-plrch]

How to make xmlns attributes to lowerCase once { strict: false, normalizeTags: true } is passed as options for parseString
