Dbms_xmldom: how to merge 2 xml's?

Hi!
xml1:
=====
<?xml ...>
<r1><t1>text1</t1></r1>
xm2:
====
[substitute 1 with 2]
merged xml:
=========
<? xml...>
<r new_attribute='M'>
<r1>...</r1>
<r2>...</r2>
</r>
How to get the merged xml using standard-functions of dbms_xmldom?
Greetings
Bjørn

The above code only add's the first node.
I changed the code little differently to
              SAXBuilder builder = new SAXBuilder();
              Document books = builder.build("D:/in.xml");
              Document onebook = builder.build("D:/out.xml");
             //trying to add second xml into the first
              books.getRootElement().addContent(onebook.getRootElement().getContent());
              new XMLOutputter(Format.getPrettyFormat()).output(books, System.out);
here is the exception from the above code:
org.jdom.IllegalAddException: The Content already has an existing parent "address"
     at org.jdom.ContentList.add(ContentList.java:218)
     at org.jdom.ContentList.add(ContentList.java:140)

How to merge XML-Data of two variables?

Hi all,
I have to combine information coming from 2 different sources (1st delivered by client input, 2nd delivered by ftp-adapter) for passing it to another service.
So there are different namespaces for the three describing xsd's (2 in, 1 out). As every structure is composed of several elements, I don't want to copy them one by one . But when copying a whole node with child elements, the target structure yields empty nodes, because the target child elements obtain the source namespace!
Using 2 XSLT's works well for each input, but in combination, the last translate deletes the information of the first one.
So, the only way to merge the data I figured out by now, is to use a XSLT for each input transforming into 2 separate Variables belonging to the same namespace and then copying the complete nodes of the two variables into the target (which of course belongs to this namespace as well).
Although there is an inconsistent indexing of the namespaces (see example), happily all data can be accessed.
<CommonData>
    <CommonData xmlns="http://TargetNamespace.com/CommonData">
      <FileInfo xmlns="http://TargetNamespace.com/CommonData">
        <Name>testfile2.txt</Name>
        <Size/>
        <DateReceived>2009-02-10T17:15:46+01:00</DateReceived>
      </FileInfo>
      <FileData xmlns:ns0="http://TargetNamespace.com/CommonData">

        </ns0:POSI>
      </FileData>
    </CommonData>
</CommonData>Now for the question:
Is this really the only way to merge variables? As it took 4 operations to achieve this, it seems to be too complicated, and therefore too inperformant to me.
BTW: In real life there would be up to 9999 positions whith much more payload to be processed ;-)
Any comments appreciated,

Well, if you only want to change namespace (no other changes) I would use a single generic XSL that changes the namespace for any XML document into a given target namespace, keeping the rest. That will require two transformation calls, but only one XSL. I'm afraid I don't have an example available, but if you google perhaps you can find it, I have seen it somewhere.
Normally when you have different namespaces the contents differ as well, though, and what you really want is a merge function. There is a way to pass two documents into a single XSL and that is to use parameters. You pass one source document the normal way and assign the other converted to a string to a paramter. You must use an assign with processXSLT in BPEL, not a transform activity. The processXSLT really takes three arguments and the third contains the parameters. Now to the difficulty - in the transformation you need to change the string into a nodeset (an XML document). In the current XPath version used by the platform there is no nodeSet function, but it is possible to write one in Java. If you have it you can select from both documents while building the third. I don't have an example handy and yes it is a bit messy as well, but much of the work only has to be done once and can be reused in other processes.

How to merge XML-Data of two variables of different namespace?

Hi all,
I am facing a problem manipulating XML data in a BPEL process. As I didn't get any response on my question in the BPEL forum, I decided to post it again in this forum. I am not very familiar with using XML up to this moment, so please don't blame me if this turns out to be a stupid question.
I have to combine information coming from 2 different sources (1st delivered by BPEL-client input "FileInfo", 2nd delivered by a ftp-adapter "FileData") for passing it to another service.
So there are 3 XSDs (2 in, 1 out), each with a different namespace. As every structure is composed of several elements, I don't want to copy them one by one. But when copying a whole node including child elements, the target structure yields empty nodes, because the target child elements maintain the source namespace!
Using 2 XSLT's works well for each input, but in combination, the last transformation deletes the information of the first one.
So, the only way to merge the data I figured out by now, is to use a XSLT for each input, transforming it into 2 separate Variables belonging to the same namespace and then copying the complete nodes of the two variables into the target (which of course belongs to the common namespace as well).
Although there is an inconsistent indexing of the namespaces (see example), happily all data can be accessed.
<CommonData>
    <CommonData xmlns="http://TargetNamespace.com/CommonData">
      <FileInfo xmlns="http://TargetNamespace.com/CommonData">

BTW: In real life there would be up to 9999 positions with much more payload (in total up to several MBs) to be processed!
Having full control of the namespaces in this case, I could think of using one namespace for all XSDs too. But would this be a better solution? Is there a golden rule on using namespaces relating to design issues?

Merging XML and XDP files

Hello!
I must build this POC for a client and the idea is merge XML and XPD files to feed a LiveCycle Output process and create PDF files.
I've built the XDP files and the XML to start things, now I need to figure out how to create the process to merge them in Workbench.
Is there any tutorial to help me with this task?
Thank you for any ideas!

Need to merge xml o/p from different sources to generate BIP Report from OA page

Hi,
Currently in our product Quoting , we are using many VO queries to generate the Report
Now we have created one data template file to combine all VO queries to generate xml o/p
The problem we are facing is that we didn't added Contracts VO query in our DT file so we need to merge
xml o/p coming from DT file and Contracts VO and pass to Process Template XDO api to generate the report
Please tell how to merge the xml o/p in OAF ?

Thanks Shridhar for reply , you provided code for xml coming from two VO
but I am having scenario where getting one xml o/p from data template file and seconf xml o/p getting from contracts api as -
ByteArrayOutputStream l_docXML = new ByteArrayOutputStream(1024);
// Here getting xml o/p from DT file
l_docXML = (ByteArrayOutputStream)this.getDataTemplateXML(transaction,"ASO","ASOPD",parameters1,null);
// Here getting xml o/p from contacts api
ContractTermsXMLGenerator.writeXML(PrintQuote,
                    (OutputStream) l_conXML,
   true,
   documentType,
   new Number(params[8]),
   new Number("0"));
// code to merge two xml into one xml m_docXML
try{
             if (l_conXML.size() > 0)
                  DOMParser dp = new DOMParser();
                  l_docIP = new ByteArrayInputStream(l_docXML.toByteArray());
                  dp.parse(l_docIP);
                  XMLDocument xDoc = dp.getDocument();
                  l_conIP = new ByteArrayInputStream(l_conXML.toByteArray());
                  dp.parse(l_conIP);
   XMLDocument cDoc = dp.getDocument();
   Node cNode = cDoc.getDocumentElement();
                  if (cNode != null)
                       Node xDocConNode = xDoc.adoptNode(cNode);
                       Node conData = xDoc.createElement("CONTRACT_DATA");
                       conData.appendChild(xDocConNode);
                       xDoc.getDocumentElement().appendChild(conData);
                     xDoc.print(m_docXML);
                     writeLog("GenerateCLMDoc::XMLMerge Complete");
           catch(Exception e)
       writeLog("GenerateCLMDoc:: Doc contract XML Merge - " + e.getMessage());
                  throw e;
    finally{
                    l_docIP.close();
                    l_conIP.close();
Please check if it is correct code , do I need to change it with code provided by you
can we chat over any messenger ?
once again thanks for your reply

Merging XML documents using DOM

I have 300 XML documents to merge. They contain structures such as:
1.xml=
<MIM>
<MIM-ENTRY>
<MIM-NUMBER>123456
</MIM-NUMBER>
</MIM-ENTRY>
</MIM>
2.xml =
<Mim>
-<Mim-entry>
<Mim-title>*604176 SUPPRESSOR OF CYTOKINE SIGNALING 3</Mim-title>
</Mim-entry>
</Mim>
3.xml=
<Mim>
<Mim-entry>
<Mim-alternative_titles_and_symbols>
<Mim-alternative_titles_and_symbols-alt>SOCS3</Mim-alternative_titles_and_symbols-alt>
</Mim-alternative_titles_and_symbols>
</Mim-entry>
</Mim>
all the XML files have this sort of structure.
Essentailly, I need to merge them (using the above as an example) to get:
<MIM>
<MIM-ENTRY>
<MIM-NUMBER>123456</MIM-NUMBER>
<Mim-title>*604176 SUPPRESSOR OF CYTOKINE SIGNALING 3</Mim-title>
<Mim-alternative_titles_and_symbols>
<Mim-alternative_titles_and_symbols-alt>SOCS3</Mim-alternative_titles_and_symbols-alt>
</Mim-alternative_titles_and_symbols>
</Mim-entry>
</MIM>
I have all the trees stored in a Vector as DOM objects.
Anyone have any ideas how to merge these documents as stated?
Any help would be most appriciated

Ah, think im begining to get you. And if I am undertstanding you correctly it might not solve my problem.
Ok, so the files exist as follows:
file1.xml
<MIN>
<MIM-1>
<MIM-2>something
</MIM-2>
</MIM-1>
</MIM>
file2.xml
<MIN>
<MIM-1>
<MIM-3>somethingelse
</MIM-3>
</MIM-1>
</MIM>
merged to give:
<MIN>
<MIM-1>
<MIM-2>something
</MIM-2>
<MIM-3>somethingelse
</MIM-3>
</MIM-1>
</MIM>
SO....
I have to bring out the nodes <MIM-2> from file1.xml and import them. in file2 appendChild will be applied to <MIM1> using those nodes.
This is really not what i was looking for.
I wanted to throw everything together. Reason? I will be merging over 300 xml documents all of which will be inserting elements at different depths. This method you describe (i think) will need the specific nodes to be extracted from each and every DOM structure. This might not be possible as the XML stuctures will change depend on the program circumstances.
I would like to just to put all the DOMS together and Tags of the same name will simply merge. to give the output above.
Or does method you descibed this actually do this?
I apologise for my stupidity in advance.

I read some example of merging file using xslt. But that involves using document() function. Since xml here is in memory I am not sure how to merge 2 xml documents.

But, how do I do that in xslt. xslt is just a template. I think I am missing a point here. I was referring to below example, only problem is that I don't have a file "file2.xml". My xml is in memory. I want to be able to use String that's in memory.
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

How to iterate xml elements using PL/SQL

Hello,
Let's say I have the following xml:
<A>
<B name="b1">
</B>
<B name="b2">
</B>
</A>
I would like to iterate over the B and sub-B elements using PL/SQL?
Any help will be appreciated.

Hi,
You can use 'PL/SQL DOM API for XMLType (DBMS_XMLDOM)'
to work with XML. You can check the example present at
http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920/a96620/xdb08pls.htm#1041419
to check how it does.
The API for the package DBMS_XMLDOM is given on the same page(http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920/a96620/xdb08pls.htm#1040676)
You can use them for your requirement.

I am trying to figure out how to merge my AD network account.

I am trying to figure out how to merge my AD network account with my Mac account. The main reason for this is wanting to log into my admin account on the Mac, and have it also log into my network account so I do not have to log into differing accounts depending on wether I am on the network or not. And I am going to be running VMware fusion with windows on top, so having one account would be essential to this.
Thanks.
P.S. I am brand new to Apple, not by choice. ;-)

Basically I want to link a network account to a local account, so that I always log into the same account, even if I do not have network access....

You never delete a Time Machine backup by dragging it to the Trash. You are supposed to use the TM application to manage the backups. What you will need to do now is to simply erase the drive using Disk Utility.

Hi Billy
Yikes - how embarassing ! Thanks for pointing out my beginners mistake there. I've fixed my code - and also implemented the substitutions of parameters like you suggested - I like that approach.
Unfortunately the end result is no better - the line
utl_http.read_text(resp,response_text);
Still returns nothing back
The headers that are coming back are

I guess I will need to try chasing it with the fastsms vendor so see if they can check my incoming request and see if there are any glaring problems. I know the xml is correct as I am now logging the xml string just before I send it and when I take that string and put it in their test form it works perfectly - something else in the puzzle is missing. I've had no experience using utl_http before - perhaps it's no possible to read the xml repsonse using this ?
Anyway, thanks for your help Billy.
ps - How do you paste your code into your message to get that formatting ?
Cheers,
Brent
