Update\modify An Xml File In Android

Question

I want to know how I can update an XML file in real time. I had this file for example:

Solution 1:

OK after long day with search and tries I have reached my Goal using Java's DOM . To modify an XML file first instantiate these to handle the XML:

DocumentBuilderFactoryfactory= DocumentBuilderFactory.newInstance();
DocumentBuilderbuilder= factory.newDocumentBuilder();
Documentdoc= builder.parse(context.openFileInput("MyFileName.xml")); // In My Case it's in the internal Storage

then make a NodeList for all "car" elements by :

NodeListnodeslist= doc.getElementsByTagName("car");

or all elements by replacing the car String with "*".

Now it well search in every node attributes till it fine the "price" value of KIA for example:

for(inti=0 ; i < nodeslist.getLength() ; i ++){
            Nodenode= nodeslist.item(i);
            NamedNodeMapatt= node.getAttributes();
            inth=0;
            boolean isKIA= false;
            while( h < att.getLength()) {
                Node car= att.item(h);
                if(car.getNodeValue().equals("kia"))
                   isKIA= true;      
                if(h == 3 && setSpeed)   // When h=3 because the price is the third attribute
                   playerName.setNodeValue("100");   
                 h += 1;  // To get The Next Attribute.
           }
}

OK Finally , Save the new File In the same location using Transformer like this :

TransformerFactorytransformerFactory= TransformerFactory.newInstance();
Transformertransformer= transformerFactory.newTransformer();
DOMSourcedSource=newDOMSource(doc);
StreamResultresult=newStreamResult(context.openFileOutput("MyFileName.xml", Context.MODE_PRIVATE));  // To save it in the Internal Storage
transformer.transform(dSource, result);

That's it :) . I hope this will helps .
