hi..
Ok now i understood you have only one xml file. and this file contains
some sub category values. first you are collect the main category
values and
display that values in listview.
when the user clicks the list item this will open another activity
and has to show the sub category values of that particular clicked
list value.
i think this is your need......
i have the solution for this...
public class XMLSourseLoader {
Document doc;
public HashMap<Object,Object> main = new HashMap<Object, Object>();
public XMLSourseLoader(String filename)
{
try {
File fXmlFile = new File(filename);
DocumentBuilderFactory dbFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
doc = dBuilder.parse(fXmlFile);
doc.getDocumentElement().normalize();
NodeList nList = doc.getElementsByTagName("maincatagory");
System.out.println(nList.getLength());
for(int i=0;i<nList.getLength();i++)
{
Element e1 = (Element)nList.item(i);
System.out.println(getTagValue("title", e1));
NodeList node1 =
e1.getElementsByTagName("subcatagory");
//this is the sub category map
HashMap<Object,Object> catagory = new
HashMap<Object,
Object>();
for(int j=0;j<node1.getLength();j++)
{
Element e2 = (Element)node1.item(j);
System.out.println("
"+getTagValue("subtitle", e2));
catagory.put(getTagValue("subtitle",
e2), books);
}
main.put(getTagValue("title", e1), catagory);
}
}
catch(Exception e)
{
System.out.println(e.toString());
}
}
public HashMap<Object,Object> getMainMap()
{
return(main);
}
public String getTagValue(String sTag, Element eElement){
NodeList nlList=
eElement.getElementsByTagName(sTag).item(0).getChildNodes();
Node nValue = nlList.item(0);
return nValue.getNodeValue();
}
}
the model xml file is
<main>
<maincatagory>
<title></title>
<subcatagory>
<subtitle></subtitle>
....
</subcatagory>
<subcatagory>
<subtitle></subtitle>
....
</subcatagory>
....
</maincatagory>
....
</main>
i just store the HashMap object inside the HashMap.
it is pretty easy. i hope this will help you...
if you have any clarification let me know....
let me know this helps you or not.
have a happy coding....
