如何使用XmlPullParser解析XML？

Question

我用XmlPullParser读取了一个Xml文件，但是当涉及到[[Dscp时，它给出了异常（未定义的实体ref（java.io.InputStreamReader@4cb5258中的位置：TEXT @ 817：4））。

i读者在此镜头之前阅读了另一幅这样的镜头直到这一切都OK。当我从xml中删除Dsec时，一切正常，并且我读取了所有xml文件。当我用Dsec读取xml时，此镜头中出现异常

之前的镜头是这样的镜头

<Shot>
        <ShotGUID>59AA1C15D3384B5691FBFB40B0FE38BD</ShotGUID>
        <Title>##Step 2-Categories of Projects</Title>
        <StartTime>00:00:40.00</StartTime>
        <EndTime>00:00:00.00</EndTime>
        <FileName>Shot0042.jpg</FileName>
        <Dscp>Step 2-Categories of Projects

Aggregate project plan identifies four separate categories of projects:

Derivative projects … those that are only incrementally different from existing offerings
Platform projects … major departures from existing offerings … the next generation
Breakthrough projects … involving a newer technology … possibly a “disruptive” technology
R&D projects … “blue sky” or visionary endeavors   

        </Dscp>

    </Shot>

这是我的代码：
 XmlPullParserFactory parserFactory;
        parserFactory = XmlPullParserFactory.newInstance();
        XmlPullParser parser = parserFactory.newPullParser();
 ByteArrayInputStream byteArrayInputStreamXmlData = new ByteArrayInputStream(bufferXMLData);
        parser.setFeature(XmlPullParser.FEATURE_PROCESS_NAMESPACES, false);
        parser.setInput(byteArrayInputStreamXmlData, "UTF-8");

 List<PageModel> pages = new ArrayList<>();
        int eventType = parser.getEventType();
        PageModel current = null;

        while (eventType != XmlPullParser.END_DOCUMENT) {
            String eltName = null;

            switch (eventType) {
                case XmlPullParser.START_TAG:
                    eltName = parser.getName();


                    if (eltName.equals("Shot")) {
                        current = new PageModel();
                        pages.add(current);
                    } else if (current != null) {

                        switch (eltName) {
                            case "ShotGUID":
                                current.setShotGUID(parser.nextText());
                                break;

                            case "StartTime": 
                                current.setStartTime(parser.nextText());
                                break;

                            case "EndTime":
                                current.setEndTime(parser.nextText());
                                break;

                            case "FileName":
                                current.setFileName(parser.nextText());
                                break;

                            case "Dscp":
                                current.setDscp(parser.nextText());     

                           case "Footer" :
                                current.setFooter(parser.nextText());
                                break;
                        }
                    }
                    break;
            }
            eventType = parser.next();
        }

经过大量研究，我意识到我不能在Dscp值中使用
