string to xml

[emma quinn]

hello
I'm trying to pass in a value to the empty tag <ds: Modulus> </ds:Modulus>..brief structure of the xml below:

<?xml version="1.0" encoding="UTF-8" ?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>  <RegisterRequest xmlns:Ds="http://www.w3.org/2000/09/xmldsig#"
  xmlns:xenc="http://www.w3.org/2001/04/xmlenc#"  Id=""  Service="http://test.xmltrustcenter.org/XKMS"  xmlns="http://www.w3.org/2002/03/xkms#">      <RespondWith>X509Cert</RespondWith>
<PrototypeKeyBinding Id="">       <ds:KeyInfo>    <ds:KeyName>http://xkms.verisign.com/keyname?jurisdiction==[e-mail]</ds:KeyName>
    <ds:KeyValue>             <ds:RSAKeyValue>               <ds:Modulus>               </ds:Modulus>
             <ds:Exponent>Aw==</ds:Exponent>               </ds:RSAKeyValue>           </ds:KeyValue>        </ds:KeyInfo>

the Java code:

//get  root of XML documentElement root = document.getDocumentElement();
System.out.println("\nDocument Element: Name = " + root.getNodeName() +", Value = "+ root.getNodeValue());
System.out.println("\nPublic BigInteger : " + KeySTore.pubBigInt);
//modulusSystem.out.println("\nPublic BigInteger : " + KeySTore.pubBigInt1);
//exponent//pubBigInt holds the modulus//mod holds conversion of modulus to stringmod = pubBigInt.toString();
 NodeList nodelist = root.getElementsByTagName("ds:Modulus");
String pk = nodelist.item(0).getFirstChild().getNodeName();
System.out.println("\nMod Name = " + pk);

When it executes the getNodeName; the println returns a value of #text.
I'm not too sure what this means. I'm trying to figure out how to pass the string as a value of the ds:Modulus tag.
I was thinking of using the setNodeValue but this is of type Node.
I'm just really unsure how to go about doing this
Please help - it would be unbelieveably appreciated.
If anyone can do this for me and it works, I will give them my programmatically created keystore/keypair/extracting
keys from keystore and breaking them down into modulus and exponents.
Or I can will have the A*Search algorithm up and running tomorrow
if that's preferred.

Emma,
I think the reason you see "#text" as the node name is that the contents of the tag is a series of blanks -- a whitespace, text node.
I'm not sure what result you would get if instead of coding

  
<ds:Modulus>               </ds:Modulus>

you coded

  
<ds:Modulus />

Since the latter version is a true no-content element, it really is different than your pair of tags with whitespace between.
If you coded

  
<ds:Modulus>123123</ds:Modulus>

or whatever, you should be able to get the value as a string, and then try to convert it to a number (int or bigint).
I'm not sure what the problem is.

If I understand you properly, the child of the first ds.Modulus Element is a Text node. Look at the JavaDocs for org.w3c.dom.Node - you will see that for a Text node, getNodeName returns "#text" and getNodeValue returns the text contents.
