How to get the full parent child path on schema validation.
Hello All,
I have been able to validate a xml document with a schema. I do have the
handler class and i'm able to print the error messages and also the line
number where the error has occured. For some reasons i need to have the
whole tree structure of the element where the error has occured. For
example, if the xml document is like this,
<a>
<b>
<c>
<d>
</d>
</c>
</b>
</a>
and the error is at the element <d>, then i need to get the whole tree
structure from the root element, like a/b/c/d.... is it possible to get that
in someway.. As far as i know, i havent found a direct method to do
that...It would be a real help if anybody could suggest me some method or
with some sample code....
Thanks
Ragu

Hi Ragu,
In addition to what rahul mentioned i think you need to set the
following feature to false .
parser.setFeature("http://apache.org/xml/features/dom/defer-node-expansion"
,false);

If you have read the docs, you will notice that the property
current-element-node is readonly. You cannot set this property. To use this
property, register an ErrorHandler with the DOM parser. Within the callback
of the registered ErrorHandler, you need to do something like this:
Element node =
(Element)parser.getProperty("http://apache.org/xml/properties/dom/current-el
ement-node");
if (node != null) {
// now you have the node from where you can
// traverse all the way back to the root
System.out.println(node.getNodeName());
System.out.println(node.getParentNode().getNodeName());
}
Hope that helps.
Cheers,
Rahul.

RE: How to get the full parent child path on schema validation.
Posted by Ron Rothblum <RO...@il.ibm.com>.
What was suggested (As I understand it) is that you override the
startElement() method of the DOMParser and then your method you call
this.getProperty(CURRENT_ELEMENT) but I'm not sure this is what you need.
Basically you have a node and want to know it's path, so why not use
node.parentNode() until you get to the document element?

Hi Rahul,
Thanks for the tip. I'm using DOM Parser. I went thru the link u gave me,
but i didnt get to know how to use it. I mean to set the property, and how
to get the element name. If you dont mind, could u plz help me as how to use
it or give me a small sample of how to use it, coz so far i have only used
setting features. I am very thankful for your time and help.

Hi Ragu,
You did not mention which parsing are you using viz. SAX/DOM parsing!.
In case you are using DOM parsing, you can try using the property
dom/current-element-node, which will give you the current node. You can then
traverse back from that node and get the full tree.
See:
http://xml.apache.org/xerces2-j/properties.html#dom.current-element-node
for more details.
