Re: [Vtd-xml-users] Xpath using token

[<jz...@xi...>]

do you know that for any text node there are unlimited ways to address
it using XPath//* will definitively do,  it  therefore can be
computationally expensive to accomplish what u look for

 For every text node I need to provde a complete xpath, this xpath
goes as column in the database.

 Getting the xpath representation of a node is neither easy nor
unique, why dont u need it in the first place?

Subject:[Vtd-xml-users] Xpath using token  

From previous suggestion I switched using this logic:   The problem
is that I am not able to get full xpath down to the leaf. I am only
able to get 2 paths. So if I have:                 value
.....   I am only getting c/d/value. Is there a trick I can use here
to get the entire path like a/b/c/d/value string ? Only other option I
see is to fall back to recursive method.       public void
navigator(byte[] b) throws NavException, XPathParseException,
   XPathEvalException, EncodingException, EOFException,
   EntityException, ParseException {
  VTDGen vg = new VTDGen();
  vg.setDoc(b);
   vg.parse(true);
  log.info [4]("File found");
  VTDNav vn = vg.getNav();   int idx = -1, type = -1;
  StringBuilder sb = new StringBuilder();   Map mapList = new
HashMap();   for (int i = 0; i < vn.getTokenCount(); i++) {
   type = vn.getTokenType(i);
   // log.info [5]("Element name ==> " + vn.toString(i) + " Token
Type "
    // + vn.getTokenType(i));    if (type ==
VTDNav.TOKEN_STARTING_TAG) {
    log.info [6]("Element name ==> " + vn.toString(i));
    sb.append(vn.toString(i) + "/");
    if (vn.contains(i, "value")) {
      do {
      i++;
      // log.info [7]("Text Element name ==> " + vn.toString(i)
      // + " Token Type " + vn.getTokenType(i));
     } while (i < vn.getTokenCount()
        && (vn.getTokenType(i) != VTDNav.TOKEN_CHARACTER_DATA)
       &      if (i < vn.getTokenCount()
       &
       addInMap(sb.toString(), vn.toString(i), mapList);
      log.info [9]("Path: " + sb.toString());
      sb.setLength(0);
     }     }    }
  }
  display(mapList);  }  private void display(Map mapList) {
  for (String key : mapList.keySet()) {
   log.info [10]("XPath => " + key + " values =>" +
mapList.get(key));
   }  }
