Unable to traverse children of child Nodes for w3c.dom class

Question

Hi Folks,
I'm trying to Traverse children of child nodes but unfortunately its not working.
Here is the snippet of my code..
String xpath = "//*[starts-with(name(), 'PosRpt')]";
          String xpath1 = "/FIXML/Batch/PosRpt/*";
          try {
               // Get all matching elements
               NodeList nodelist = XPathAPI.selectNodeList(doc, xpath);
               if (nodelist.getLength() < 0)
                    System.out.println("Element not found");
               else
                         System.out.println("xpath element found");
               // Process elements in nodelist
               for (int i=0; i<nodelist.getLength(); i++){
                    Element element = (Element)nodelist.item(i);
                    System.out.println("Element name - " + element.getTagName());
                    GetAttributes(element);
                                        Node currentnode = (Node) nodelist.item(i);
                    NodeList childlist = currentnode.getChildNodes();
                    int xx = childlist.getLength();
                    System.out.println("No of child elements = " + xx);
                    for (int y=0; y<childlist.getLength(); y++){
                         Element element1 = (Element)childlist.item(y);
                         System.out.println(y + " Child Element name - " + element1.getTagName());
                         GetAttributes(element1);
                         if ("Pty".equals(element1.getTagName())&& element1.hasChildNodes()){
//     THIS IS WHERE I THINK THE PROBLEM IS *****                                                             
                              Node child = element1.getFirstChild();
                              System.out.println("Node name - " + child.getNodeName()+
                                        " and node value is = " + child.getNodeValue());
                              NamedNodeMap attrs = child.getAttributes();
                              if (child.hasAttributes()){
                              for(int x= 0; x<attrs.getLength(); x++){
                                   Attr attr = (Attr) attrs.item(x);
                                   System.out.println("attribute Name - " + attr.getNodeName());
                                   System.out.println("attribute value - " + attr.getNodeValue());     
Sample of XML..snippet
- <PosRpt RptID="273558126" BizDt="2005-07-13" ReqTyp="0" Ccy="USD">
<Pty ID="OCC" R="21" />
- <Pty ID="00299" R="4">
<Sub ID="C" Typ="26" />
</Pty>
and this is what the result snippet is...
Child Element name - Pty
attribute Name - ID
attribute value - 00299
attribute Name - R
attribute value - 4
Node name - #text and node value is =
WHERE DID NODE #text CAME FROM.
I'M BAFFLED.
ANY IDEAS??
THANKS IN ADVANCE.

Alas, it is probably working fine.
What you are seeing in the "extra" text elements are newlines.
Change your print statement from:
System.out.println("Node name - " + child.getNodeName()+
" and node value is = " + child.getNodeValue());to
System.out.println("Node name - " + child.getNodeName()+
" and node value is =` " + child.getNodeValue() + "'");You will see something like
and node value is =`
If I have
<a>
<b>xxx</b>
</a>
a will have three child nodes. The first and third will be text nodes with a newline, and the second will be the b child element.
If I have
<a><b>xxx</b></a>
a will only have one child -- the element b.
Also be aware that if you are processing XML data with SAX and have large
blocks of text in an element, there is no requirement for all parsers to return a single text object. They are free to decide how many text blocks they create.
