我在Android development转换XML to JSON其中包括时遇到此错误CDATA tag。它在正常情况下工作正常Java。

我用过Library。

org.json.

 public Document fetchXMLHTTP(String httpUrl) {
    try {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setIgnoringComments(true);
        factory.setCoalescing(true); // This removes CDATA Tag and converts it ", this doesn't work in Android 



        Log.v("xml_parser", "Coalescing Aware: " + factory.isCoalescing());
        if(factory.isNamespaceAware()){
        }
        DocumentBuilder builder = factory.newDocumentBuilder();
        URL uri = new URL(httpUrl);
        Document doc = builder.parse(new InputSource(uri.openStream()));
        doc.normalizeDocument();
        NodeList xml = doc.getElementsByTagName("avatar");
        Log.v("xml_parser", "Avatar Content: " + xml.item(0).getTextContent());
        return doc;
    } catch (Exception e) {
        e.getStackTrace();
    }
    return null;
}

public String generateNewXML(Document doc, String tag) {
    try {
        NodeList xml = doc.getElementsByTagName(tag);
        StringWriter sw = new StringWriter();
        Transformer serializer = TransformerFactory.newInstance().newTransformer();
        serializer.transform(new DOMSource(xml.item(0)), new StreamResult(sw));
        String newXML = sw.toString();
        System.out.println("New XML: " + newXML);
        return newXML;
    } catch (Exception e) {
        e.getStackTrace();
    }
    return "";
}

我得到了这种类型的Error.

XML 有两种类型tags，如下所示：
