Yes you can , in the code section below :

for (int i = 0; i < nl.getLength(); i++) {
        // creating new HashMap
        HashMap<String, String> map = new HashMap<String, String>();
        Element e = (Element) nl.item(i);

        if(parser.getValue(e, KEY_ID).equals(et.getText().toString())){
        // adding each child node to HashMap key => value
        map.put(KEY_ID, parser.getValue(e, KEY_ID));
        map.put(KEY_NAME, parser.getValue(e, KEY_NAME));
        map.put(KEY_COST, "Rs." + parser.getValue(e, KEY_COST));
        map.put(KEY_DESC, parser.getValue(e, KEY_DESC));

        // adding HashList to ArrayList
        menuItems.add(map);
}else{
 }

As you can see , you just retrieve the id from XML and compare it to the id you get from the Edit text. If they match add it to the hashmap else dont !

Hope this helps!
