Document vs. DocumentFragment
What is the best practice for generating fully-functional XMLDocuments from transforms using XSLProcessor? Most of the processXSL() methods generate DocumentFragments. Why? Sometimes when I append a node from a DocumentFragment to a new XMLDocument (using importNode() or adoptNode()), subsequent xpath operations performed on that XMLDocument won't work or won't produce any nodes.
Also, if I use XMLQuery.setXSLT() and then call getXMLDOM(), I won't get the entire document. Why is this (when if I call getXMLString() and parse the resulting String, my Document will always be complete)?
Also, how can I "Oraclize" an Document using a different DOMImplementation. I can serialize the foreign Document and re-parse it using Oracle's DOMParser, but that seems to defeat the whole concept of using the Document interface in the first place: what's the best practice for using Document objects with different DOMImplementations with Oracle code?
Thanks!
processXSL can either return a DocumentFragment or write the result to a PrintWriter/OutputStream.
It returns DocumentFragment because of section 3.1 in the XSLT 1.0 specification:
"it is possible that a result tree will not be a well-formed XML document;...When the source tree is created in some other way, for example by using the DOM, the usual restrictions are relaxed for the source tree as for the result tree."
This means that you can legally write a transform that produces the result:
<foo/>
<foo/>
<foo/>
which is a list of elements, but not a legal XML document (which would require a single outermost element. DocumentFragment is the only DOM object that allows an arbitrary sequence of DOM nodes that XSLT can produce.
If subsequent xpath operations don't work after successfully appending child nodes to a tree, then that is a bug. Try the latest XDK 9.0.2 Beta which fixes some bugs in that area, and if you still have a problem, report it with a simple testcase here in the forum.
Need to understand more about your XMLQuery.setXSLT() issue and what part of the document is "left out".
You cannot "Oracleize" an org.w3c.dom.Document whose concrete class was created with a different DOMImplementation. We don't support the ability to transform from an arbitrary Document interface for performance reasons. This keeps our XSLT engine very fast. You'll find that engines that accept an arbitrary DOM are never as fast as when they can use their own internal structures.
You can serialize and parse like you've suggested, or tree-walk and fire SAX events as another approach.

How to get document from documentfragment
hi,
I tried the xsl Sample Code from Oracle XDK,
The Output is a documentfragment.
How can I build a domdocument out of that documentfragment?
Sorry about the short description, but I think XML Gurus
know what I mean ;-).
Thanks
DeltevA DocumentFragment is a 'minimal' Document object.

My application uses xml for data persistency. My question is:
1. is there a way to partially edit part of the xml file? because if I make some small changes to my data, i wish to save just that part.
2. Or I can just save the whole thing and overwrite the orignal file entirely, is this a common practice?
thanks!A javax.xml.transform.Transformer transform method stores a Documentnode or a DocumentFragment node.
Transformer transformer;
Document document;
Node node;
DocumentFragment documentFragment=document.createDocumentFragment();
documentFragment.appendChild(node);
transformer.transform(new DOMSource(document), new StreamResult(new File("c:/output/output.xml")));
transformer.transform(new DOMSource(documentFragment), new StreamResult(new File("c:/output/outputNode.xml"))); -

nullTwo other problems with XSL and print:
first one :
XSL :
<SCRIPT langage="Javascript" type="text/javascript" src="scripts/erreur.js"></SCRIPT>
DocumentFragment.print() produce :
<SCRIPT langage="Javascript" type="text/javascript" src="scripts/erreur.js"/>
=> IE5.5 don't load the file !!, it required syntaxe like <SCRIPT ...></SCRIPT> to load.
the second one :
XSL:
<TD><IMG src="images/menuleft.gif"/></TD>
DocumentFragment.print() produce :
<TD>
<IMG src="images/menuleft.gif">
</TD>
processXSL(xslSS, xmldoc, System.out) produce :

Why a cariage return ?? it cause prisentation failure when you want to specifie the size off the cell !!

I'm working through some examples in the O'Reilly, Oracle XML Applications.
I have the following in MoreoverIntoNewsstory.java
package mypackage2;
import oracle.xml.parser.v2.*;
import java.io.InputStream;
import org.w3c.dom.*;
import java.net.URL;
import java.sql.Connection;

public static void main( String[] arg ) throws Exception {

theXSL = "c:\\moreover-to-newsstory.xsl";
// Create a DOM Parser to Parse the News Document
DOMParser dp = new DOMParser();
dp.parse( theNews );
// Parse the document at the URL specified in theURLString
XMLDocument moreoverNewsDoc = dp.getDocument();
// Search for a list of all the matching articles and print the count
NodeList nl = moreoverNewsDoc.selectNodes("moreovernews/article");
int articleCount = nl.getLength();
System.out.println("Received " + articleCount + " articles...");
// Load the XSL Stylesheet from the top-level directory on CLASSPATH
InputStream xslstream = Object.class.getResourceAsStream(theXSL);
XSLStylesheet transform = new XSLStylesheet(xslstream,null);
// Create an instance of XSLProcessor to perform the transformation
XSLProcessor processor = new XSLProcessor();
// Transform moreoverNewsDoc by theXSL and get result as a DOM Document Fragment
DocumentFragment df = processor.processXSL(transform, moreoverNewsDoc);
// Create a new XML Document and append the fragment to it
Document result = new XMLDocument();
result.appendChild(df);
// Pass the transformed document (now in canonical format) to OracleXMLSave
Connection conn = Examples.getConnection();
OracleXMLSave oxs = new OracleXMLSave(conn,"newsstoryview");
int rowsInserted = oxs.insertXML( result );
conn.commit();
conn.close();
System.out.println("Inserted " + rowsInserted + " articles...");
When I debug this, it errors at the line:

The error is:
Exception breakpoint occurred at line 785 of XSLProcessor.java.

Any advice?I thought that might be it to. Tried that, get the same error. I did verify the name and location of the file as well. The error message had the additional notes below:

SQLException "Expected 'EOF'" when extracting XMLType from ResultSet
Hi,
I am trying to implement a Java method that returns the nodes matching a given xpath expression. The query is working fine and the code is mostly working. The problem is getting the information out of an XmlType in Java.
The query is as follows:
---8<--
select extract(res, '/xdb:Resource/xdb:Contents'||:xpath,
'xmlns:xdb="http://xmlns.oracle.com/xdb/XDBResource.xsd" '||:ns) node
from resource_view
where under_path(res, :path) = 1;
---8<--
xpath = '//n:PostalCode'
ns = 'xmlns:n="uri:cosmos:schema:company:1.0"'
path = '/home/contactmgr'
And the Java code:
---8<---
resultSet = statement.executeQuery();
while (resultSet.next())
OPAQUE opaque = (OPAQUE) resultSet.getObject(1);
if (opaque != null)
XMLType myNode = XMLType.createXML(opaque);
String testString = myNode.getStringVal();
Document testDocument = myNode.getDOM();
---8<---
The testString contains the expected result (messy, but workable), i.e. "<PostalCode xmlns="uri:cosmos:schema:company:1.0">GU1 4LY</PostalCode>\n<PostalCode xmlns="uri:cosmos:schema:company:1.0">TW18 4AQ</PostalCode>\n". These are the two postal codes in the first document.
The call to myNode.getDOM() fails with an SQLException and a message of "Expected 'EOF'".
I appreciate that the returned xml is a fragment and as such it shouldn't be possible to return an org.w3c.dom.Document instance. However, when I try using myNode.getDocumentFragment() I still get an SQLException but with no message or any other details.
The method is currently expected to return a list of Nodes.
Any ideas?The Oracle 10G XDB Developers Guide (http://download-west.oracle.com/docs/cd/B13789_01/appdev.101/b10790/xdb03usg.htm#sthref209) offers the following:
"The extract() function returns the node or nodes that match the XPath expression. Nodes are returned as an instance of XMLType. The results of extract() can be either a document or DocumentFragment."
To provide for the fact that an XPath expression may match multiple nodes in any given document, I modified the query to use xmlsequence(). This should then return an array of XmlType instances.
--8<--
select xmlsequence(extract(res, '/xdb:Resource/xdb:Contents'||?,
'xmlns:xdb="http://xmlns.oracle.com/xdb/XDBResource.xsd"
'||?)) nodes
from resource_view
where under_path(res, ?) = 1;
--8<--
The Java JDBC code then looks like this:
--8<--
OPAQUE[] myRawNodes = (OPAQUE[]) myResultSet.getArray(1).getArray();
for (int i = 0; i < myRawNodes.length; i++)
OPAQUE myOpaque = (OPAQUE) myRawNodes[ i ];
if (myOpaque != null)
XMLType myNode = XMLType.createXML(myOpaque);
myCollection.add(myNode.getDOM());
--8<--
Testing this out however, I get the following exception:
java.sql.SQLException: Internal Error: makeJavaArray doesn't support type 2007
To re-iterate: my goal is to:
a) evaluate an XPath expression that will return a list of nodes against all the documents under a particular path in the resource_view;
b) extract all the returned nodes using JDBC; and
c) return the collection of nodes to the caller.
Any ideas? -
How can I import an XML DOM document into another?
Dear all,
I'm using the following bit of code:
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;
to import a DOM document into another DOM document, so that it converts something like this:
<?xml= .... etc>
<Data></Data
to:
<?xml= .... etc>
<Data>
<Yellow>Butter</Yellow>
<White>Marzipan</White>
</Data>
Instead, what it is doing is:
<?xml= .... etc>
<Yellow>Butter</Yellow>
<White>Marzipan</White>
I know that it is stripping out the <Data> elements because of the call to the replaceChild
function, after getting the element's parent, but if I change
Node replaceNodeParent = replacedNode.getParentNode();
to
Node replaceNodeParent = replacedNode;
I get an error about node node being accessible.
Please help!

Hi,
I have installed JDeveloper 9i rc2 and the following code (it runs correctly on JDeveloper 3.2.3)
Document d = new XMLDocument();
d.appendChild(d.createElement("d"));
Document d2 = new XMLDocument();
d2.appendChild(d2.createElement("d2"));
DocumentFragment rootNode = new XMLDocumentFragment();
Element e = d2.getDocumentElement();
d2.removeChild(e);
--> rootNode.appendChild(e); /* It is here that the Exception is throwned */
d.getDocumentElement().appendChild(rootNode.cloneNode(true));
throws the following exception:
oracle.xml.parser.v2.XMLDOMException: Node doesn't belong to the current document.
Any clue why this happen?

How to save a DocumentFragment which is not in XML
Hi,
i want to make an export from a view object as CSV-file. To achieve this i have made a stylesheet, that converts a xml to a text format.
DocumentFragment oDF = tNode.transformNode(xslt);
And from here i have the problem: How could i save the DocumentFragment to my harddisk? (Inserting that DocumentFragment in a XMLDocument doesn't work because it is no longer in xml-format)
Thanx,
MarcHey Marc,
I'd rather use a code like this:
DOMParser parser = new DOMParser();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
PrintWriter pw = new PrintWriter(baos);
try
String xslUrl = "yourXSLdocument.xsl";
parser.parse(is); // the xml document input stream
XMLDocument doc = parser.getDocument();
XSLProcessor xp = new XSLProcessor();
try
XSLStylesheet xsl = xp.newXSLStylesheet(new FileInputStream(xslUrl));
xp.processXSL(xsl, doc, pw);
String processedDoc = baos.toString();
System.out.println(processedDoc); // Here you go!
catch (XSLException xsle)
JOptionPane.showMessageDialog(null, xsle.toString(), "XSLException", JOptionPane.ERROR_MESSAGE);
catch (SAXException saxe)
JOptionPane.showMessageDialog(null, saxe.toString(), "SAXException", JOptionPane.ERROR_MESSAGE);
Please tell me is this is addressing your problem...

XMLType.getDOM().createDocumentFragment() NOT org.w3c.dom.DocumentFragment ?
Hi,
i have an XMLType variable xml ( (XMLType) ResultSet.getObject() ) and i want to create an org.w3c.DocumentFragment by : xml.createDocumentFragment(). But i get a ClassCastException.
oracle.xdb.dom.XDBDocumentFragment does not implement org.w3c.dom.DocumentFragment ?
Thanks
Alessandro ScottiI think that oracle.xdb.dom.XDBDocumentFragment is "internal" oracle view of org.w3c.dom.DocumentFragment
because xmltype!= DOM Document.One question:
how I can implement org.w3c.dom.DocumentFragment.getOwnerDocument() method?
Regards. -
Appendchild from DocumentFragment
Hello:
I need help in understanding the issue with the code specifically documentfragment. On searching the forums, I could find an alternate way of getting the required result. However I am interested in understanding why my original code with DocumentFragment does not work. I am not able to understand why the Node created from DocumentFragment wont get added as Child in the main XML after I have imported it.
I am running this on 10g - version 10.2.0.4 database.

Appending a DocumentFragment to XMLDocument (acutal)
(Sorry for previous incorrect post, which was incomplete; this is the correct post.)
I've been having a surprisingly difficult time trying to do this simple thing: append a DocumentFragment to an XMLDocument.
Here is my method; there are several print statements in here for debugging:
* This method joins two XML elements to form a single XML document: the individual
* SDI element, in an XMLDocument, and the non-SDI parts of the record, in a
* DocumentFragment. The method assumes that each element has just one child node
* containing the value. Also assumed is a class object, inputroot, which is a
* Node that is the root element of an XMLDocument.
private void joinSDI(XMLDocument sdidoc, DocumentFragment frag)
NodeList nonSdiNodeList = frag.getChildNodes();
Node tempRecRoot = sdidoc.getDocumentElement();
if (DEBUG3)
System.out.println("length of node list = "+nonSdiNodeList.getLength());
for (int i = 0; i < nonSdiNodeList.getLength(); i++)
System.out.println("iteration "+i);
Node node = nonSdiNodeList.item(i);
Node n = node.getFirstChild(); // this is the SDI
System.out.println("source name = " + node.getNodeName());
System.out.println("source value = " + n.getNodeValue());
Node tempNode = sdidoc.createTextNode(n.getNodeName());
tempNode.setNodeValue(n.getNodeValue());
System.out.println("new node type = " + tempNode.getNodeType());
System.out.println("new node name = " + tempNode.getNodeName());
System.out.println("new node value = " + tempNode.getNodeValue());
tempRecRoot.appendChild(tempNode);
// Now append this record XML doc to the insertion document we are building.
System.out.println("the constructed input doc:");
try {
sdidoc.print(System.out);
catch (IOException e)
System.out.println("Caught IO parse exception : "+e.getMessage());
this.inputroot.appendChild(sdidoc);
return;
Here is the input xml doc:
<?xml version="1.0" encoding="US-ASCII" standalone="no"?>
<!DOCTYPE hydro SYSTEM "hydro.dtd">
<hydro>
<ROW num="1">
<HM_SITE_CODE>HDMLC</HM_SITE_CODE>

<VALUE>333</VALUE>
<SOURCE_ID>4</SOURCE_ID>
<VALIDATION>Z</VALIDATION>
</ROW>
</hydro>
Here is what I get for output (including the debugging statements):
length of node list = 4
iteration 0
source name = DATE_HOUR
source value = 14-APR-00 12:00:00
new node type = 3
new node name = #text
new node value = 14-APR-00 12:00:00
iteration 1
source name = VALUE
source value = 644.039978
new node type = 3
new node name = #text
new node value = 644.039978
iteration 2
source name = SOURCE_ID
source value = 4
new node type = 3
new node name = #text
new node value = 4
iteration 3
source name = VALIDATION
source value = Z
new node type = 3
new node name = #text
new node value = Z
the constructed input doc:
<?xml version = '1.0'?>
<ROWSET><ROW num="1"><SITE_DATATYPE_ID>2158</SITE_DATATYPE_ID></ROW>14-APR-00 12:00:00644.0399784Z</ROWSET>

at Hdbdom.main(Hdbdom.java:695)
I am puzzled by several things here:
- why i s the node name #text in the new document?
- why are my node values all jammed together in the output instead of becoming separate nodes?
- how do I set the doctype in the output document?
- why do I get a null pointer when attempting to append this output doc to the inputroot object?
Any help would be much appreciated,

Excellent! Thank you!
That worked, except that the fragment gets appended after the trailing </ROW> tag.
Here's an example of the incorrect append:
<?xml version = '1.0'?>
<ROWSET>
<ROW num="1"> <SITE_DATATYPE_ID>2158</SITE_DATATYPE_ID>
</ROW>

<VALUE>644.039978</VALUE>
<SOURCE_ID>4</SOURCE_ID>
<VALIDATION>Z</VALIDATION>
</ROWSET>
Is there an easy way to append such that my elements appear after the <SITE_DATATYPE_ID> element within the <ROW> tag?
TIA!

Steve,
Nevermind my previous question; I answered it myself -- for those interested, the (very easy) solution was:
sdidoc.getDocumentElement().getFirstChild().appendChild(frag);

Error while resetting a cleared document
Hi everyone,
I am getting an error while resetting a cleared invoicing document 'Document xxxxxxxxxxx with origin R4 can not be reversed'. Please guide me how can we reset the clearing of this document.
Thanks and RegardsHi,
You need to reset all clearing for the corresponding FICA document for the print document.
Reset the clearing for the document no. mentioned in the output for EA13 execution.
You need to reset all the clearing for the document, before reversing the same.
To get all the clearing document, go to DFKKOP table, enter the FICA document no. (for the print document on FPL9). Get all AUGBL documents,
Alternatively, you can go on to FPL9 screen, double click on the consumption document, in the basic data you will see the clearing date (if it is cleared), expand the view their (click on + sign), you will se the clearing document no,
Pass the above clearing document no, to FP07, and once all the clearing is reset for the invoice, you can reverse the corresponding invoice through EA13.
Regards,
Rajesh Popat
