Saxparser无法解析HTML数字字符引用。 显示的问号

Question

I am trying to Parse an xml which is containing — and &#8217 numeric character references. On parsing it gives me output as "?". it is not only these two, any HTML/XMl numeric character references in the xml creates this issue. only pre-defined entities are getting accepted by the saxparser

i use defaulthandler saxparser. system out in character method shows me a question mark for the numeric character references.

i did lot of googling, everywhere i see that usage of numberic character refernce should not create any issue.

Any help?

System.out in character method shows me a question mark for the numeric character references.

That sounds like a character encoding problem of your output / console. The following works with JSE 7

public static void main(String[] args) throws Exception{ SAXParser parser = SAXParserFactory.newInstance().newSAXParser();

    XMLReader reader = parser.getXMLReader();
    reader.setContentHandler(new ContentHandler() {

        // other methods omitted 

        @Override
        public void characters(char[] ch, int start, int length)
                throws SAXException {
            System.out.println(new String(ch, start, length));

        }
    });

    FileReader fReader = new FileReader("/tmp/HelloWorld.xml");
    reader.parse(new InputSource(fReader));
    fReader.close();
}

With XML File:

<?xml version="1.0" encoding="UTF-8"?>
<Test>
Hello World&#8217;
</Test>

Output: Hello World'

Have you tried to look at the incomming character array using a debugger?
