XML parsing with DOM

Question

I am parsing xml file from SDcard and display it in textview. whenever i tried to access, nothing will displayed

InputStream in = new FileInputStream("/sdcard/jokes.xml");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(in);
doc.getDocumentElement().normalize();
NodeList nodeLst = doc.getElementsByTagName("jokes");

for (int s = 0; s < nodeLst.getLength(); s++) {
    Node fstNode = nodeLst.item(s);
    System.out.println("" + fstNode);
    if (fstNode.getNodeType() == Node.ELEMENT_NODE) {
        Element fstElmnt = (Element) fstNode;
        NodeList fstNmElmntLst = (NodeList) fstElmnt.getChild("item");
        Element fstNmElmnt = (Element) fstNmElmntLst.item(0);
        NodeList fstNm = ((Node) fstNmElmnt).getChildNodes();
        System.out.println("Number of joke description : "+ ((Node) fstNm.item(0)).getNodeValue());

    }
}

This is the code which i did to parse xml file from sdcard. can anyone tell where i made a mistake or if you have better option pls let me know.

Answer 1

Try this for your loop:

for (int s = 0; s < nodeList.getLength(); s++)
{
    Node firstNode = nodeList.item(s);
    NodeList nodes = firstNode.getChildNodes();
    for (int i = 0; i < nodes.getLength(); i++)
    {
        Node node = nodes.item(i);
        //print node info
    }
}

I think you just import wrong class because there is no method called "getChild" in org.w3c.dom.Element.
Please import "org.w3c.dom.Element;" in stead of "import android.sax.Element;"
