如何在Android中解析Sdcard中的xml文件
我有这个XML：
<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<alllogs count="5">
<log number="+919876543210" time="1365589432804" date="Wed Apr 10 15:53:52 GMT+05:30 2013" type="2" duration="0" new="1" name="360 chhotein" numbertype="2" numberlabel="null" />
<log number="+919876543210" time="1365595887261" date="Wed Apr 10 17:41:27 GMT+05:30 2013" type="2" duration="0" new="1" name="360 chhotein" numbertype="2" numberlabel="null" />
<log number="+919876543210" time="1365596387590" date="Wed Apr 10 17:49:47 GMT+05:30 2013" type="2" duration="0" new="1" name="360 chhotein" numbertype="2" numberlabel="null" />
<log number="+919876543210" time="1365596787051" date="Wed Apr 10 17:56:27 GMT+05:30 2013" type="2" duration="0" new="1" name="null" numbertype="null" numberlabel="null" />
<log number="0041786095382" time="1365740469738" date="Fri Apr 12 09:51:09 GMT+05:30 2013" type="2" duration="0" new="1" name="null" numbertype="null" numberlabel="null" />
</alllogs>
我使用的解析器是android原生XMLPullParser
我无法更改XML格式，但如果值得的话，我可以使用另一个兼容android的解析器。
如果它不是很清楚，它必须适合这样的课程：
try {
String file = Environment.getExternalStorageDirectory() + File.separator + "SmsContactsBackup/logs/calllogs_20130412125502.xml";
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser parser = factory.newPullParser();
FileInputStream fis = new FileInputStream(file);
parser.setInput(new InputStreamReader(fis));
Log.d("Response", ""+convertStreamToString(fis));
int eventType = parser.getEventType();
String name = null;
while (eventType != XmlPullParser.END_DOCUMENT)
{
//String name = parser.getName();
if(eventType == XmlPullParser.START_DOCUMENT) {
System.out.println("Start document");
}else if(eventType == XmlPullParser.START_TAG) {
name = parser.getName();
if (name.equalsIgnoreCase("alllogs")){
count = Integer.parseInt(parser.getAttributeValue("", "count"));
}else if(name.equalsIgnoreCase("log"))
{
phone_no.add(parser.getAttributeValue("", "number"));
}
System.out.println("Start tag "+parser.getName());
}else if(eventType == XmlPullParser.END_TAG) {
name = parser.getName();
System.out.println("End tag "+parser.getName());
}
eventType = parser.next();
}
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (XmlPullParserException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
事件类型不正确，IOException。
最后我得到了这样的解决方案，我用Dom解析
public class MainActivity extends Activity {
ArrayList<String> mImageLink;
ArrayList<String> phone_no;
int count;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mImageLink = new ArrayList<String>();
phone_no = new ArrayList<String>();
try {
File file = new File("mnt/sdcard/Backup_Apps/call_logs/calllog_35777569.xml");
InputStream is = new FileInputStream(file.getPath());
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(is));
doc.getDocumentElement().normalize();
NodeList nodeList = doc.getElementsByTagName("alllogs");
for (int i = 0; i < nodeList.getLength(); i++) {
Node node = nodeList.item(i);
Element fstElmnt = (Element) node;
mImageLink.add(fstElmnt.getAttribute("count"));
count = Integer.parseInt(mImageLink.get(i));
}
NodeList n = doc.getElementsByTagName("log");
for (int j = 0; j < count; j++) {
Node node = n.item(j);
Element fstElmnt = (Element) node;
phone_no.add(fstElmnt.getAttribute("number"));
}
} catch (Exception e) {
System.out.println("XML Pasing Excpetion = " + e);
}
}
}
XML解析。 我怎样才能得到孩子的孩子？
你有一个工作的例子。 它基于Java，在Android设备中完美工作。
try {
File SDCardRoot = Environment.getExternalStorageDirectory()
.getAbsoluteFile();
File myDir = new File(SDCardRoot.getAbsolutePath() + "/.ABC"
+ "/.Config");
File file = new File(myDir, "config.xml");
InputStream inputSource = new FileInputStream(file.getPath());
DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
Document doc = dBuilder.parse(inputSource);
Element element = doc.getDocumentElement();
element.normalize();
NodeList nList = doc.getElementsByTagName("item");
for (int i = 0; i < nList.getLength(); i++) {
Node node = nList.item(i);
if (node.getNodeType() == Node.ELEMENT_NODE) {
Element eElement = (Element) node;
String id = eElement.getElementsByTagName("id").item(0)
.getTextContent();
eElement.getElementsByTagName("name").item(0)
.getTextContent();
eElement.getElementsByTagName("image_updated").item(0)
.getTextContent();
eElement.getElementsByTagName("image").item(0)
.getTextContent();
eElement.getElementsByTagName("colorcode").item(0)
.getTextContent();
}
}
} catch (Exception e) {
e.printStackTrace();
}
