Just two quick questions

[Horny Porno-thologist]

Dear everyone,
I managed to get most of my code (nesting documents etc.) worked out,
but there are a few niggles.

The first one is as follows:

My first document is:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<WfMessage>
<ATO_ATO>
<ATO_FileLoadedIntoSystem>No</ATO_FileLoadedIntoSystem>
<ATO_RawXML>XML DATA HERE</ATO_RawXML>
</ATO_ATO>
</ProcInstInputData>
</ProcessTemplateExecute>
</WfMessage>

What I want to do is to insert my second XML file between the tags so that
it reads:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<WfMessage>
<ATO_ATO>
<ATO_FileLoadedIntoSystem>No</ATO_FileLoadedIntoSystem>
<ATO_RawXML>
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
(XML data in here...snipped for brevity)
</ATO_RawXML>
</ATO_ATO>
</ProcInstInputData>
</ProcessTemplateExecute>
</WfMessage>

(By the way, I do need the second root in the nested document!)
I've come up with some code that comes up with the following XML:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<WfMessage>
<ATO_ATO>
<ATO_FileLoadedIntoSystem>No</ATO_FileLoadedIntoSystem>
(data in here...snipped for brevity) // TAGS AND ROOT MISSING !!!
</ATO_ATO>
</ProcInstInputData>
</ProcessTemplateExecute>
</WfMessage>

Which is nearly what I need when I use the following code:

ATO_document = builder.parse( "D:\\ATO.xml" );
XML_document = builder.parse( "D:\\XML.xml" );
NodeList replacedNodeList = XML_document.getElementsByTagName("ATO_RawXML");
Node foundnode = replacedNodeList.item(0);
if ( foundnode != null )
{
Node modfiedReplacedDocument = replaceNode(XML_document, ATO_document,
foundnode);}
else
{
// error message here.
}
}
and replaceNode is defined as follows:

public static Node replaceNode(Document replacedDocument, Document
replacingDocument, Node replacedNode)
{
//Create a documentFragment of the replacingDocument

DocumentFragment docFrag = replacingDocument.createDocumentFragment();
Element rootElement = replacingDocument.getDocumentElement();
docFrag.appendChild(rootElement);

//Import docFrag under the ownership of replacedDocument

Node replacingNode =
((replacedDocument).importNode(docFrag, true));

//In order to replace the node need to retrieve replacedNode's parent

Node replaceNodeParent = replacedNode.getParentNode();
replaceNodeParent.replaceChild(replacingNode, replacedNode);
return replacedDocument;
}

I've tried using insertBefore functions in the replaced document to
artificially recreate the <ATO_RawXML> tags, but the code
grumbles that the parent element is missing. I'm sure a solution is very
simple
but I am losing my hair over this. Can anyone suggest anything (other than
a lotion to keep my hair in) ?

Best wishes

You can't do this. An xml declaration may only occur at the start of
a document. There is no way to have it embedded inside another
document.

Thanks Richard,

Now all I have to do is solve the second problem - the tag being
replaced. I can see why it is doing this, but I don't know how
to circumvent the problem, unless it requires regenerating the
"missing" tag.... can anyone suggest a very easy way of doing this?

Best wishes
