why org.apache.xerces.parsers.SAXParser does not skip BOM in utf8 encoded xml?

Question

I have an xml with utf8 encoding. And this file contains BOM a beginning of the file. So during parsing I am facing with org.xml.sax.SAXParseException: Content is not allowe

Answer 1

I've experienced the same problem and I've solved it with this code:

private static InputStream checkForUtf8BOM(InputStream inputStream) throws IOException {
    PushbackInputStream pushbackInputStream = new PushbackInputStream(new BufferedInputStream(inputStream), 3);
    byte[] bom = new byte[3];
    if (pushbackInputStream.read(bom) != -1) {
        if (!(bom[0] == (byte) 0xEF && bom[1] == (byte) 0xBB && bom[2] == (byte) 0xBF)) {
            pushbackInputStream.unread(bom);
        }
    }
    return pushbackInputStream;
}
