XML root elements

Hi i am writing a sql select query to create an xml file.
SELECT
XMLELEMENT("data",
XMLATTRIBUTES('http://smile.mit.edu/shelf/' as "wiki-url",
'SIMILE JFK Timeline' as "wiki-section"),
XMLELEMENT("event",
XMLATTRIBUTES(e.IMP_DATE as "start",
e.NAME||': '|| e.ECCTS as "title",
e.IMP_DATE as "end")
from monica_tab2 e;
When this query runs, it appears to show the data tags as elements for every record. I want this to be a root element so that it only appear once for all the events.
Is there any way i can do this? Examples will be appreciated
Thanks

Try using the XMLAGG function...
SELECT
XMLELEMENT("data",
             XMLATTRIBUTES('http://smile.mit.edu/shelf/' as "wiki-url",
                           'SIMILE JFK Timeline' as "wiki-section"),
             XMLAGG(XMLELEMENT("event",
                               XMLATTRIBUTES(e.IMP_DATE as "start",
                                             e.NAME||': '|| e.ECCTS as "title",
                                             e.IMP_DATE as "end")
from monica_tab2 e;

Indesign CS3 XML Root element?? , Java Script

Is there any way to tag the root element using javascript?
The three usual ways without JS would be:
Rename the tag in the tag pallete.
Select and Retag the Element in the Structure.
Or import an xml to replace the structure.
This is the closest information I could find, thanks to Dave Saunders

Read XML root element tag in Java

Is there any way I can read the tag of the root element? Based on the tag, I process the XML differently.
Thank you.

I think I figured it out. I can accomplish this by using the getTagName method. Sorry for the lack of detail in my original question.
For those interested, I have a class that has XML passed to it. Depending on what the root tag name is, different activities needed to take place. I needed a way to read the tag in order to determine what actions needed to be performed.
Thank you.

Add dynamic namespace declaration into xml root element

Hello all,
i've have two scenarios (mail to mail and file to file) with the same issue : no namespace in my XML file and i have to create one 'dynamically' from XML values.
Example :
<root>
<name>test</name>
<email>test</email>
<schema>schemaID</schema>
</root>
Now I want to add infos into the root element for namespace declaration and so on, without expansion of the xsd. I've must use the value from the field schemaID.
Example:
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns: namespace="http://test.de/schemaID">
<name>test</name>
<email>test</email>
</root>
I've already done it before through XSLT but it wasn't dynamic !! I don't know how to do it in XSL and i am not a java expert.
Someone got an idea ?
Thanks,
Jean-Philippe.

Hi,
If you want to add name space at mapping level two options
1)Using XSLT Mapping ,its very easy,google it to get sample XSLT code ,it will solve your problem.
2)Using java mapping,in java mapping use regular expression code ,using regex(Regulkar expresion)we can add any content in message at any level.

Hi Christopher,
Call the below code as a javamappinf in the operation mapping... So now your operation mapping will have two mappings one to convert source to target XML and second this java mapping which will add namespace to your target xml
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;
import com.sap.aii.mapping.api.AbstractTransformation;
import com.sap.aii.mapping.api.DynamicConfiguration;
import com.sap.aii.mapping.api.DynamicConfigurationKey;
import com.sap.aii.mapping.api.StreamTransformationException;
import com.sap.aii.mapping.api.TransformationInput;
import com.sap.aii.mapping.api.TransformationOutput;
import com.sap.aii.mapping.api.InputHeader;
public class JavaMapping extends AbstractTransformation {
     public void transform(TransformationInput arg0, TransformationOutput arg1) throws StreamTransformationException {
     getTrace().addInfo("JAVA Mapping Called");
     //Input payload is obtained by using arg0.getInputPayload().getInputStream()
     String inData = convertStreamToString(arg0.getInputPayload().getInputStream());
     String outData = inData.replaceFirst("<root>", "<root xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xsi:noNamespace=\"http://test.de/test.xsd\">");
     try
     //8. The JAVA mapping output payload is returned using the TransformationOutput class
     // arg1.getOutputPayload().getOutputStream()
          arg1.getOutputPayload().getOutputStream().write(outData.getBytes("UTF-8"));
     catch(Exception exception1) { }
     public String convertStreamToString(InputStream in){
     StringBuffer sb = new StringBuffer();
     try
     InputStreamReader isr = new InputStreamReader(in);
     Reader reader =
     new BufferedReader(isr);
     int ch;
     while((ch = in.read()) > -1) {
          sb.append((char)ch);}
          reader.close();
     catch(Exception exception) { }
     return sb.toString();

Create Root Element in XML

Hi Experts,
I am develpoing a program to generate xml file as output. I am using the method CL_IXML and other interfaces to generate the xml data. Here I need to create a root element. I did search in SDN but I couldnot found anything to generate xml root element.
My output should be like this:
<?xml version="1.0" encoding="UTF-8"?>
<Request Version="11.1" IssuerID="1">
        <CreatePurchaseRequest
            RequestID="123456"
            Commonname="test"
        </CreatePurchaseRequest>
</Request>
Can anybody plz suggest how can I generate the root element Request here?
Regards,
Ranganadh.

Thanks Sandra,
My issue got resolved.
I just created the root element using the method create_sample_element and set the attributes using set_attributes method.
Thanks for your help.
w_ixml = cl_ixml=>create( ).
      w_document = w_ixml->create_document( ).
      w_root = w_ixml->create_document( ).

        RAISE EXCEPTION TYPE cx_cmx_da_exception
          EXPORTING
            textid = cx_cmx_da_exception=>cx_cmx_da_error_internal.
      ENDIF.
      w_encoding = w_ixml->create_encoding(
                             character_set = 'utf-8'
                             byte_order    = if_ixml_encoding=>co_none ).
      w_document->set_encoding( w_encoding ).
      w_element_inv1 = w_document->create_simple_element(
                  name = 'OrbiscomRequest'

      w_element_inv1->set_attribute( name = 'Version'
                                     namespace = ''
                                     value = '11.1' ).
      w_element_inv1->set_attribute( name = 'IssuerID'
                                     namespace = ''
                                     value = '1' ).

Adding namespace prefix to the XMLa root element

I am facing a problem in our application. I am assigning an XML content to a XSD variable. While assignment operation is performed the prefix of the XML root element alone is getting replaced with default namespace, though the source XML has the prefix. Please let me know if any patch or workaround is available to address this issue.
Thanks!

Hi All,
we are also facing the same issue, Please provide the solution if anyone knows. We are also using the SOA Suite 11g Version.

(Fatal Error) Start of root element expected

Hi,
When running the app, I have got
Error(1,1): <Line 1, Column 1>: XML-20108: (Fatal Error) Start of root element expected.
I think it is due to some libraries missed inside the app. How to resolve this?
Regards,

did u check this file?
C:\dp\jdev11113\Login\ViewController\public_html\mdssys\mdx\Login4.jspx.rdf
actually these files gets created which we normally ignore.. you can remove this file.. and wrok normally without this error.. make sure that you have Login4.jspx file
or fix this file an check if there is a xml root element like
<?xml version="1.0" encoding="UTF-8"?>

The markup in the document following the root element must be well-formed.

I have my XML root element that looks like this:
<DataResponseOfListOfSite xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www
.w3.org/2001/XMLSchema" xmlns="http://xxxxxx/webservices/sites/">
and I get the error "The markup in the document following the root element must be well-formed."
If I use this it works fine:
<DataResponseOfListOfSite xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www
.w3.org/2001/XMLSchema" xmlns:xsi="http://xxxxxx/webservices/sites/">
Does anyone know why I have to have the xmlns:xsi="" instead of just xmlns=""
If I paste this XML into any validator, it says that its good, so I dont know why Flex is complaining about it.

In the first one you have two namespaces both with the same prefix.
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" and xmlns:xsi="http://xxxxxx/webservices/sites/"

Getting oracle.xml.parser.v2.XMLParseException: Start Of root Element

Hi All,
I am getting below error while creating STUB/Skeleton in Jdeveloper to call a web service from OAF Page But getting below error while trying to creating Stub/Skeleton to call weservice
ERROR:
oracle.xml.parser.v2.XMLParseException: Start Of root Element
Any suggestion on This
P.S: I am calling a third party web service so can not able to make changes in XML
Regards,

Possibility is that there is a problem in the XML that is being passed. Can you double check with the third party software? Also check if you can try it outside OA Framework first and then if its tested you can integrate with EBS.

Oracle.xml.parser.v2.XMLParseException: Start of root element expected

Hi,
while trying to get a soapelement from xml file, i have the error : oracle.xml.parser.v2.XMLParseException: Start of root element expected
the code i m using is as follow :
public static SOAPMessage XMLDocToSOAP(String soapBodyAsString ) throws SAXException, IOException,
SOAPException,
ParserConfigurationException {
SOAPMessage message = null;
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
InputStream is = new ByteArrayInputStream(soapBodyAsString.getBytes());
Document doc = dbf.newDocumentBuilder().parse(is);
MessageFactory factory = MessageFactory.newInstance();
message = factory.createMessage();
message.saveChanges();
SOAPBodyElement element = message.getSOAPBody().addDocument(doc);
return message;
}

Looks like the XML you are passing is not valid. Check that the XML complies the the definition.
Also can you post a XML that works and the one that fails.
cheers
James

Just for anyone else who hits this problem: I encountered the same issue with an XML document that XMLSpy claims is quite well formed. I opened the document in a hex editor, and there at the from was a three-byte byte order marker - the marker that I believe the UTF-8 standard says is optional. I removed these three bytes, and the file was parsed correctly.
In this case, the XML file was created using a Microsft DOM (save).
My solution is to make the java parser - as I use it - a tad more robust: Open the file and create an input stream - a pushback input stream. Read the first three bytes; if they are NOT a BOM, then push those bytes back. Now - in any case - give the stream to the parser to read.
try {
// Open file for reading.
f = new File(path);
FileInputStream fis = new FileInputStream(f);
PushbackInputStream pis = new PushbackInputStream(fis);
byte[] buf = new byte[3];
pis.read(buf, 0, 3);
if (! (buf[0] == 0x00EF) && (buf[1] == 0x00BB) && (buf[2] == 0x00BF) ) {
pis.unread(buf, 0, 3);
builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
doc = builder.parse(pis);
catch (Exception x) {
x.printStackTrace();
}

No root element found in xml

NO ROOT ELEMENT FOUND IN XML. Can someone help me in corrcting this Error ?
Regards,

NO ROOT ELEMENT FOUND IN XML. Can someone help me in
corrcting this Error ? That means the XML document is either missing the surrounding <element> ... </element> pair or has more than one pair at the base level of the document. Resolve that and you are done.
Now ... given that I am probably 4,000+ km away from you and can not see your screen, please look at your question and ask yourself whether you have given sufficient information for troubleshooting. <g>

XML "Document root element is missing"

i have made a research in the forums but i have no definite solution about the error.
my flash client sends XML stream to my ServerSocket. and i want to parse these XML datas.
Document XMLDoc;
DocumentBuilderFactory Factory = DocumentBuilderFactory.newInstance();
DocumentBuilder Builder = Factory.newDocumentBuilder() ;
InputSource Is = new InputSource(new BufferedReader(new InputStreamReader(Sock.getInputStream(),"UTF-16LE")));
XMLDoc = Builder.parse(Is);
But now i have problem called "Document root element is missing". My XML stream comming from flash client :
// Actionscript code :
XDoc = new XML("<?XML version=\"1\"?><LOGIN><USERNAME>KHARON</USERNAME><PASSWORD>485009</PASSWORD></LOGIN>");
----- The XML data i want to sent to ...
<?XML version="1"?>
<LOGIN>
<USERNAME>KHARON</USERNAME>
<PASSWORD>485009</PASSWORD>

What is the problem ?

now ?
// Actionscript

XSock.connect("127.0.0.1",6667);
XDoc = new XML("<?xml version=\"1.0\"?><LOGIN><USERNAME>KHARON</USERNAME><PASSWORD>ew2345dfs</PASSWORD></LOGIN>");

but the result

ihave made a research ( i am newbee in XML) and i have made some declerations like <!DOCTYPE LOGIN <!Element ...
i have declared root element with DOC type decleration. but the same error. :|
since 2 days i am working over these, but solution = null
