我真的在搜索这个,但找不到答案,我的情况并非如此
似乎离我所读过的文档和例子太远了,但是......
我只是解析一个XML文件,嵌套元素与xmlpullparser,和
将数据存储在自定义对象的ArrayList中
几乎所有东西都可以,但我最终得到了2x太多的物体......
从我收集的到现在,问题来自a
每次END_TAG
事件发生后都会触发START_TAG
事件,然后解析继续,我会重新遇到{I}正常看到的END_TAG
。
这是我的解析循环:
int eventType = parser.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
String name;
switch (eventType) {
case XmlPullParser.START_DOCUMENT:
Log.i(TAG, "getLoadedXmlValues __ START_DOCUMENT");
shop = new ArrayList();
break;
case XmlPullParser.START_TAG:
name = parser.getName();
Log.i(TAG, "getLoadedXmlValues __ START_TAG name = " + name);
if (name.equalsIgnoreCase("WELCOME_TEXT")) {
waitingScreenText = parser.nextText();
currentContent = waitingScreenText;
} else if (name.equalsIgnoreCase("ARTIST")) {
//Log.i(TAG, "getLoadedXmlValues __ creating new artist object");
currentArtist = new Artist();
} else if (currentArtist != null) {
if (name.equalsIgnoreCase("NAME")) {
currentArtist.setName(parser.nextText());
currentContent = currentArtist.getName();
//Log.i(TAG, "getLoadedXmlValues __ artist object exists, setting values. NAME = " + currentArtist.getName());
} else if (name.equalsIgnoreCase("PICTURE")) {
currentArtist.setPicture(parser.nextText());
currentContent = currentArtist.getPicture();
} else if (name.equalsIgnoreCase("DESCRIPTION")) {
currentArtist.setDescription(parser.nextText());
currentContent = currentArtist.getDescription();
} else if (name.equalsIgnoreCase("TATTOOS")) {
currentTattoos = new ArrayList<>();
} else if (name.equalsIgnoreCase("TATTOO")) {
currentTattoos.add(parser.nextText());
currentContent = "adding a tattoo";
} else if (name.equalsIgnoreCase("DRAWINGS")) {
currentDrawings = new ArrayList<>();
} else if (name.equalsIgnoreCase("DRAWING")) {
currentDrawings.add(parser.nextText());
currentContent = "adding a drawing";
}
Log.i(TAG, "getLoadedXmlValues __ START_TAG content = " + currentContent);
}
case XmlPullParser.END_TAG:
name = parser.getName();
Log.i(TAG, "getLoadedXmlValues __ END_TAG name = " + name);
if (name.equalsIgnoreCase("TATTOOS")&& currentArtist !=null&& currentTattoos !=null) {
currentArtist.setTattoos(currentTattoos);
} else if (name.equalsIgnoreCase("DRAWINGS")&& currentArtist !=null&& currentDrawings !=null) {
currentArtist.setDrawings(currentDrawings);
} else if (name.equalsIgnoreCase("ARTIST")&& currentArtist !=null) {
//Log.i(TAG, "getLoadedXmlValues __ END_TAG :: add artist to shop");
shop.add(currentArtist);
}
}
这是我的xml :(我从网上下载文件,然后写下它的内容
在内部存储上的文件中
builder.append(line).append("\n");
)
<?xml version="1.0" encoding="utf-8"?>

这是一个日志提取:
START_DOCUMENT
START_TAG name = datas
END_TAG name = datas
START_TAG name = DATE_CREATED_TIMESTAMP
END_TAG name = DATE_CREATED_TIMESTAMP
END_TAG name = DATE_CREATED_TIMESTAMP
START_TAG name = WAITING_SCREEN
END_TAG name = WAITING_SCREEN
START_TAG name = WELCOME_TEXT
END_TAG name = WELCOME_TEXT
END_TAG name = WAITING_SCREEN
START_TAG name = ARTISTS
END_TAG name = ARTISTS
START_TAG name = ARTIST
END_TAG name = ARTIST
START_TAG name = NAME
START_TAG content = artiste 1
END_TAG name = NAME
START_TAG name = PICTURE
[...]
如您所见,无论元素是否包含嵌套元素,开始标记始终会导致START_TAG
和END_TAG
被触发...
我试图记录我的本地xml文件来检查它,它是正确的,所以问题必须来自我的while循环...
我完全迷失了为什么会这样......
答案 0 :(得分:0)
只需在每个break;
case
即可
