Converting java.lang.String to a XML Node

Question

Hi,
how do you convert a straight forward string like ..
"<nodename>this is the node value</nodename>" to a org.w3c.dom.Node....??
This way it would be easier to use appendNode() to add temporary nodes & build up a document.

Answer 1

ur app will perform poor if u r going to instantiate
Document builder often.and u cant append the node ,like
the way u r trying do.
the node has to belong to the same document.
u have to necessarily create node/text node, from this document and append it .
Option two: read content from 1 file as a string append
the second value from dealer_info and then create a document from the result String.but make sure ur string is in valid XML format.

Ok let me tell you what exactly i want to do, so that
you can advise me better. Please tell me, what could
be done to avoid the error below.
//start from an existing template xml file
Document d =
parseXmlFile("D:/www/Detailcache/detail.xml", false);
Node root=d.getFirstChild();
//append dealer information to the root node
Node dnode=getDealerInfo(currentDealer);
System.out.println("Node
Info-->"+dnode.getNodeName());
root.appendChild(dnode);
//<-------------------Line175
//Dealerinfo module returning the parent node
public Node getDealerInfo(DealerInfo currentDealer) {
try {
DocumentBuilderFactory factory =
ctory = DocumentBuilderFactory.newInstance();
String
String dealer_info="<dealer_info><dealer_address>930
Rockbridge
ave</dealer_address><dealer_country>USA</dealer_countr
</dealer_info>";byte buf[] = dealer_info.getBytes();
ByteArrayInputStream in = new
n = new ByteArrayInputStream(buf);
BufferedInputStream bis = new
s = new BufferedInputStream(in);
Document dealer_info_doc =
o_doc = factory.newDocumentBuilder().parse(bis);
Node dealer_info_node=
o_node= dealer_info_doc.getFirstChild();
return dealer_info_node;
} catch (Exception e) {e.printStackTrace();}
return null;
My problem is 'root.appendChild(dnode);' returns an
error :
Node Info-->dealer_info
org.apache.crimson.tree.DomEx: WRONG_DOCUMENT_ERR:
That node doesn't belong in this document.
