Android parse Plist file
提问by Darko Petkovski
Hello Im trying to parse an plist file that contains array of dict's. Im trying to do this using xmlwise. The content of the plistfile is here
你好，我试图解析一个包含 dict 数组的 plist 文件。我正在尝试使用xmlwise来做到这一点。plistfile 的内容在这里
So far I only have this in my activity and im getting the content of the plistfile, but how to parse the content into an arraylist?
到目前为止，我的活动中只有这个，并且我正在获取 plistfile 的内容，但是如何将内容解析为数组列表？
Map<String, Object> properties = null;
try {
InputStream inputStream = getResources().openRawResource(R.raw.first_5);
BufferedReader br = null;
try {
br = new BufferedReader(new InputStreamReader(inputStream));
StringBuilder sb = new StringBuilder();
String line;
while ((line = br.readLine()) != null) {
sb.append(line);
}
properties = Plist.fromXml(sb.toString());
// TODO do something with the object here
Log.v("--", properties.values() + " " + properties.size());
Log.v("--", "OB "+properties.get());
} catch (Exception e) {
e.printStackTrace();
} finally {
br.close();
}
}

Quick question. What should be the content of the ArrayList? I was wondering if you are mentioning about a list of Objectin you Map<String, Object> propertiesmap then why cant you just get the values from the map as
快速提问。ArrayList 的内容应该是什么？我想知道，如果你提的关于列表Object在你Map<String, Object> properties的地图，则为什么不能你只是从地图为获取值
Map<String, Object> properties = new HashMap<String, Object>();
List<Object> plist = new ArrayList<Object>(properties.values());
Apart from that checking your plist the structure is like a Dict root element and a list of Dicts in it. I assume you need to get this as a list. If so consider using Android PList parserby longevitysoft. This is simple and opensource. Its basically a SAXParser parsing Apple PList.
除了检查您的 plist 之外，结构就像一个 Dict 根元素和其中的 Dict 列表。我假设您需要将此作为列表。如果是这样，请考虑使用长寿软件的Android PList 解析器。这是简单和开源的。它基本上是一个 SAXParser 解析Apple PList。
You can then iterate through this array and get approriate object. In your xml its and array of Dict object, so you could do something like this
然后您可以遍历这个数组并获得适当的对象。在你的 xml 和 Dict 对象数组中，你可以做这样的事情
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import com.longevitysoft.android.xml.plist.PListXMLHandler;
import com.longevitysoft.android.xml.plist.PListXMLParser;
import com.longevitysoft.android.xml.plist.domain.Array;
import com.longevitysoft.android.xml.plist.domain.Dict;
import com.longevitysoft.android.xml.plist.domain.PList;
import com.longevitysoft.android.xml.plist.domain.PListObject;
public class PlistReader {
public static void main(String[] args) throws Exception {
PListXMLParser parser = new PListXMLParser();
PListXMLHandler handler = new PListXMLHandler();
parser.setHandler(handler);
parser.parse(readFile("plist.xml"));
PList pList = ((PListXMLHandler) parser.getHandler()).getPlist();
Dict root = (Dict) pList.getRootElement();
// This Array class is java.util.ArrayList<PListObject> underneath the
// covers
Array theList = root.getConfigurationArray("Objects");
for (PListObject obj : theList) {
switch (obj.getType()) {
case DICT:
Dict dictionaryObj = (Dict) obj;
// dictionaryObj.getConfigurationObject(key);
// dictionaryObj.getConfigurationInteger(key);
// dictionaryObj.getConfiguration(key);
// dictionaryObj.getConfigurationArray(key)
break;
case STRING:
com.longevitysoft.android.xml.plist.domain.String stringObj = (com.longevitysoft.android.xml.plist.domain.String) obj;
break;
default:
break;
}
}
}
private static String readFile(String path) throws IOException {
byte[] encoded = Files.readAllBytes(Paths.get(path));
return new String(encoded);
}
}
When i tried parsing your xml i got some exception. That was because the PListXMLHandler was checking for localName and not qualifiedName. This could be easily fixed by checking for localName in startElement() and endElement() methods like.
当我尝试解析您的 xml 时，出现了一些异常。那是因为 PListXMLHandler 正在检查 localName 而不是qualifiedName。这可以通过在 startElement() 和 endElement() 等方法中检查 localName 来轻松解决。
if(isEmpty(localName)){
localName = qName;
}
Hope this helps.
希望这可以帮助。

You can also try Google dd-plist.jarlibraries or SAXON parse for parsing plist.
您还可以尝试使用 Googledd-plist.jar库或 SAXON parse 来解析 plist。
Go through this conversion :
通过这个转换：

https://code.google.com/p/plist/wiki/Examples http://developer.android.com/reference/javax/xml/parsers/SAXParser.html
You can use dd-plist jar for doing this, Download dd-plist.jar from Google its nice and fast.
您可以使用 dd-plist jar 来执行此操作，从 Google 下载 dd-plist.jar 非常好且快速。
