Java use sax to parse xml files. Can't get the correct content when coming up &amp

Question

I have some issues with parsing xml files by sax.

The Java contenthandler code looks like this:

boolean rcontent = false;

@Override
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
    if (qName.equalsIgnoreCase("content")) {
        rcontent = true;
    }
}

@Override
public void characters(char ch[], int start, int length) throws SAXException {
    if (rcontent){
        System.out.println("content: " + new String(ch, start, length));
        rcontent = false;
    }
}

Xml file content is like this:

But the output is:

I want to say

which is not complete.

It's likely that characters(...) is being called multiple times for the single <content> block. Try something like

StringBuilder builder;

@Override
public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
    if (qName.equalsIgnoreCase("content")) {
        builder = new StringBuilder();
    }
}

@Override
public void characters(char ch[], int start, int length) throws SAXException {
    if (builder != null){
        builder.append(new String(ch, start, length));
    }
}

@Override
public void endElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
    if (builder != null) {
        System.out.println("Content = " + builder);
        builder = null;
    }
}
