Problem of using "org.w3c.dom.Node" class

I try to use removeChild(child) method of "org.w3c.dom.Node" object. it don't work.
is it better to do child=null;

child=null does nothing to the dom object
removeChild works fine. You're just confused.
You would need more info to have any chance of fixing the problem.

How to add node value using org.w3c.dom.Document?

Hi ,
I'm using org.w3c.dom.Document to deal with xml files. I could successfully add nodes , and their attributes. However I could not add a value of the node. (e.g. <myNode>I couldn't add this value</myNode>)
does anyone know how to deal with this?
I tried subNode.setNodeValue("the value i can't add"); whereas the subNode is an instance of org.w3c.dom.Node... i know this is interface i of course used the concrete class
org.apache.crimson.tree.ElementNode
but when I used the subNode.getNodeValue() i simply got null?
can u plz help me?
thanks in advance

Reading the API documentation for the Node interface might help. At least you wouldn't be surprised when the results are exactly what the documentation says they will be.
What would really help would be forgetting the idea that an Element can have a value. Text nodes have values, though, so create a Text node and make it the child of the Element node.

Cost of creating org.w3c.dom.Node

I am trying to create an xml of cached data at run time. I need to know if this would increase the response time considerably ..?
Is there any documents which talk about the cost of creating nodes(e.g.within loops) ..?
public Node createnode(Document d, String node_name, int node_value) {
org.w3c.dom.Node temp_element_node, temp_text_node;
temp_element_node = d.createElement(node_name);
temp_text_node = d.createTextNode(node_name);
temp_text_node.setNodeValue(node_value + "");
temp_element_node.appendChild(temp_text_node);
return temp_element_node;
Has anybody implimented a pool of nodes(like pool of database connections). Any information is appreciated!

It would certainly depend somewhat on which parser you were using, but i can't imagine it would be any more costly than any other type of object.

NoSuchMethodError with org.w3c.dom.Node.getTextNode()

Hi,
I got a trouble with this method. I developped my app with Eclipse and jdk 1.5.
I used the endrosed mechanism for updating xalan and xerces in my jre.
Everything works fine on my computer, but as I want to run my app on an other machine, I got this error.
I put a copy of my jre on the other machine and I launch the app from this jre. It seems the endorsed jars are taken in account, but it still doesn't work.
Thanks for your help.

I found ths solution.
In my jre was missing the endorsed Dom.jar, found at jaxp.dev.java.net. to overwrite org.w3c.dom standard classes.

Casting a org.w3c.dom Node to a org.dom4j Node

Does anybody know how I can cast (convert) a w3c.dom Node to a dom4j Node?
If I just trying casting the w3c node "(org.dom4j.Node)" it throws an exception...

I have a org.w3c.dom.Node after calling HttpUnit's getDOMSubtree() method.
Now I would like to change that Node to an org.dom4j.Node so i can use dom4j's Node.valueOf() method on it.
Any idea how?

Set Name of org.w3c.dom.Node (= chang the TagNam)

Hi all,
How I can set name of my object org.w3c.dom.Node.
In fact, this is an Element and I want to chang the tag <label> to <LABEL> befort write out DOM to XML File
thanks a lot

org.w3c.dom.Element interface does not have a setTagName() method.
Implement interface org/w3c/dom/contentModel/CMElementDeclaration which has a setTagName() method.

DOMException on executing org.w3c.dom .Node#getNodeValue()

Hi All,
I have a query related to Node#getNodeValue(). As per java doc, this call can throw DOMException.
DOMException - DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.
Is there a way to upfront figure out that when we call getNodeValue() on given Node , we'll get this exception. In other words, can we check the max size of DOMString with the stored value.
thanks
Edited by: user772587 on Mar 29, 2012 8:49 PM

I do not necessarily understand the question.
But if you are talking about java with java variable as place holder of the return of getNodeValue() method, then you have the size limit of string of 2 billion bytes long or about, making that exception call practically academic. Image a node value of that long, you would face other problems long before calling a getNodeValue().

Org.w3c.dom.Node isleaf?

Hi all
is there any way to get if a w3c node isLeaf?
I thought that i can see if the first chils ia a text node then i can say that is a leaf but i'm not sure taht is the right way.
Thanks!!

It is not that simple.
In the following chunk:
<a>
text
</a>the first child of is a text field, so by your premise it is a leaf. But, the first child of <a> is also a text field (the newline and prefix spaces before ), so is it a leaf also?
What about:
<html>
Some text with a highlight ENTRY.
</html>
Is the a leaf?
Perhaps the kind of messages you are trying to parse do not allow nested content. If so, then your concept of "leaf" is really "leaf for a special kind of XML file."

Org.w3c.dom.Document to/from String ?

I need to be able to parse (once) an XML string, and then pass the parsed object around to/from different objects.
I tried to use org.w3c.dom.Document,
generated by javax.xml.parsers.DocumentBuilder .
HOWEVER - I don't see any way to parse an xml String!
The doc-builder parse() method accepts either a file/url, or an InputStream.
When I tried to use the StringBufferInputStream I found-out it is deprecated, and that I should use StringReader.
BUT I cannot parse using StringReader ! (the method parse() doesn't work with it)
Is there anyway to parse a String to create a Document ?
========================================================
And that's only HALF my problem:
I did parse an input file into a Document, to experiment a little.
I then wanted to convert it to an XML String - but couldn't.
How do I get the xml String from a Document ?
I cannot: How do I save it to a file ?
I must say that under .NET both tasks are TRIVIAL:
XmlDocument.LoadXML()
XmlDocument.OuterXml
Thanks
Meir

The doc-builder parse() method accepts either a file/url, or an InputStream.This isn't true. Look it up again. There are overridden versions of parse() that use File, InputSource, InputStream, or String. The String one isn't what you want, because the String it takes is a URL pointing to the XML and not the XML itself. The File one doesn't work for you because you don't have a file, and you've already said why the InputStream one doesn't work for you.
So that leaves the version that takes an InputSource. So, what is an InputSource anyway? You could look it up just by clicking on the link in the API docs...
