Android: Parsing Xml

Is there a short way to parse XML string in Android

Try this,

 public void parseXml(){
    try {

        XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
        factory.setNamespaceAware(true);
        XmlPullParser xpp = factory.newPullParser();

        xpp.setInput( new StringReader( "<foo>Hello World!</foo>" ) ); // pass input whatever xml you have
        int eventType = xpp.getEventType();
        while (eventType != XmlPullParser.END_DOCUMENT) {
            if(eventType == XmlPullParser.START_DOCUMENT) {
                Log.d(TAG,"Start document");
            } else if(eventType == XmlPullParser.START_TAG) {
                Log.d(TAG,"Start tag "+xpp.getName());
            } else if(eventType == XmlPullParser.END_TAG) {
                Log.d(TAG,"End tag "+xpp.getName());
            } else if(eventType == XmlPullParser.TEXT) {
                Log.d(TAG,"Text "+xpp.getText()); // here you get the text from xml
            }
            eventType = xpp.next();
        }
        Log.d(TAG,"End document");

    } catch (XmlPullParserException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

How to parse an xml file in android?

I found a way to access the attribute values. I have explained all the lines in the comments.

 DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
 DocumentBuilder builder = factory.newDocumentBuilder();

 Document doc = builder.parse(file);   // We can use inputstream or uri also

 NodeList node = doc.getElementsByTagName("rootfile"); //  gets list of all nodes by specified tag name.

 Node map = node.item(0); // Getting the specific node

 NamedNodeMap namedNodeMap = map.getAttributes();  // Getting attributed of the nodes.
            
 Node file_path = namedNodeMap.getNamedItem("full-path"); // getting the partcular node attribute

 String path = file_path.getNodeValue();  // This will give the value of full-path 

Parsing XML on Android

Your loop should look like this:

Node node = nList.item(i);
if (node.getNodeType() == Node.ELEMENT_NODE) 
{
     Element element = (Element) node;
     tv1.setText(tv1.getText()+"\nName : " + getValue("name", element)+"\n");
}

where getValue :

private static String getValue(String tag, Element element)
{
   NodeList nodeList = element.getElementsByTagName(tag).item(0).getChildNodes();
   Node node = nodeList.item(0);
   return node.getNodeValue();
}

How to parse xml in android-java?

You need to iterate ingredients child nodes like you do it for recipe tag.

But the more easy way is to use XPath.

How to parse xml string?

Well You Need to go to res > values > String.xml

you need to set your String in String.xml

In above image you need go to String xml

<resources>
<string name="app_name">DocumentRecord</string>
<string name="your_title">your title</string>
<string name="your_url"><a href="your_website"></a></string></resources>

How to fix Error Parsing XML in android development?

You have 2 problems.

First one : remove white space in textColor attribute :

<TextView
            android:id="@+id/number"
            android:text="Number"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="right"
            android:textColor="#373D4D"
            android:background="#FFFFFF"/>

Second one is :

<Button
     android:text="<<"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:id="@+id/curr"
     android:layout_weight="1" />  

You should extract the String << causing an issue at compilation. extract string resource like so :

<Button
      android:text="@string/yourstring"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/curr"
      android:layout_weight="1" />

Then in strings.xml (/res/values/strings.xml) add the created resource :

<string name="yourstring"><![CDATA[<<]]></string>
