Android解析Plist文件

Question

你好，我试图解析一个包含字典数组的plist文件。我尝试使用xmlwise来做到这一点。plistfile的内容在这里

到目前为止，我只有这个在我的活动，我得到的plistfile的内容，但如何解析内容到数组列表?

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();
    }
}

快速提问。数组列表的内容应该是什么?我想知道你是否提到Map<String, Object> properties映射中的Object列表，那么为什么你不能从映射中获取

的值呢?

Map<String, Object> properties = new HashMap<String, Object>();
List<Object> plist = new ArrayList<Object>(properties.values());

除了检查pllist之外，该结构就像一个Dict根元素和其中的Dicts列表。我猜你需要把这个作为清单。如果是这样，可以考虑使用长寿软件的Android PList解析器。这是简单和开源的。它基本上是一个解析苹果列表的SAXParser。

然后可以遍历该数组并获得合适的对象。在xml中，它是Dict对象的数组，你可以这样做

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);
    }
}

当我试图解析你的xml时，我得到了一些例外。这是因为PListXMLHandler正在检查localName而不是qualifiedName。这可以很容易地通过检查startElement()和endElement()方法中的localName来修复，例如。

if(isEmpty(localName)){
    localName = qName;
}

您也可以尝试Google dd-plist.jar库或SAXON解析来解析plist。

执行下面的转换:

https://code.google.com/p/plist/wiki/Exampleshttp://developer.android.com/reference/javax/xml/parsers/SAXParser.html

你可以使用dd-plist jar来做这些，从Google下载dd-plist.jar，它又好又快。

我把一个例子工作为我从谷歌代码云。林克在这里。http://plist.googlecode.com/svn-history/r61/trunk/src/com/dd/plist/XMLPropertyListParser.java
