How to enable non-IANA encodings when using javax.xml.stream.XMLStreamReader

Question

I'm using javax.xml.stream.XMLStreamReader to parse XML documents. Unfortunately, some of the documents I'm parsing use non-IANA encoding names, like "macroman" and "ms-ansi". For example:

<?xml version="1.0" encoding="macroman"?>
<foo />

This causes the parse to blow up with an exception:

javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,42]
Message: Invalid encoding name "macroman".

Is there any way to provide a custom encoding handler to my XMLStreamReader so that I can augment it with support for the encodings I need??

I'm assuming you don't have the ability to alter the stream so that it doesn't contain the encoding line? XMLStreamReader has its limitations, and this is one of them. — Dylan

Its unfortunate, but you may better be served by choosing a different XML library. — Dylan

@Dylan I'm not producing these documents, just consuming them, so I have no control over the encoding line unfortunately. Are there other XML libraries that are more flexible? — Laurence Gonsalves

You could wrap the input stream with a transformer that replaces the non-standard charset with the equivalent charset that XMLStreamReader does understand.
