Storing and parsing an XML document

Hi everybody,
does anybody know how to store (clob) and to parse (query) and XML document? can you give me an example and/or some useful information?
Thanx in advance,
Ettore

Hi, first try determine how much time does the parsing xml get,
you could just remove insert lines, and count,
if the time is similar it means that parsing xml has great infulance on total time,
otherwise there is insert affection you could try ue forall loop syntax insted of for ( just FORALL currentNode IN 0 .. xmldom.getLength(nodeList) - 1 LOOP) or
direct load using 'insert into <table_name> .. as select',
'forall' minimize conext switches it could help
to achive direct load you need first rewrite your procedure to function in order to return table, (table of object ), so your insert could look like
insert into SWTable
as select * from table
(cast
USP_FILEINFOINSTANCEINSERT(
URLFile =>x
lComputerID =>y) as SWTable_t)
where SWTable_t - table of SWTable_o
SWTable_o - object with all SWTable's atributes

Issue with parsing an xml document and namespaces

I am having an issue when parsing an xml document that includes a namespace.

INSERT INTO NDE_CIG_STATUS_TRANSACTIONS(PMT_ID) VALUES (trec.pmt_id);
END LOOP;
COMMIT;
END ParseXML;
If I remove the namespace, everything works just fine. The issue is that I cannot remove the namespace.
Anyone have any suggestions on how I can get the xslprocessor.selectNodes to recognize my namespace?

Unable to display tree view; Error when parsing an XML document (Premature end of file.)

Hi folks,
I am using a cascaded mapping in my OM. I have a graphical mapping followed by the Java mapping. It is a flat file to IDOC mapping. Everything works fine in Dev but when I transport the same objects to QA, the Operation mapping though it doesn't fail in ESR testing tool, gives the following message and there is no output generated for the same payload which is successfully tested in DEV. Please advise on what could be the possible reasons.
Unable to display tree view; Error when parsing an XML document (Premature end of file.)

kalyan,
There seems to be an invalid xml payload which causes this error in ESR not generating the tree view. Please find the similar error screenshot and rectify the payload.

Parsing an xml document inside a Thread

Hi Friends
I have to do some processing in my application for which i need to use multithreading.
Inside every new thread created i have to parse an xml document using s parsing tool like castor or jibx.
My question is that is it possible to parse a xml document inside a new thread everytime it gets created.
is it a good coding practice as it involves java code to do it.
Thanks
Vikeng

Hi
Thanks for the reply.
Well i need to do some kind of a batch processing in my application.
I need to parse an xml document and upload the data i get after parsing into columns in the database.
Since its a batch what i was asking was is it possible to do it for every request as batch needs to handle hundreds of records during the daily or nightly sync.
Is it a good practice to do parsing for every record in a batch
Thanks
VikengI don't get it. One batch is one document, and that document contains e.g. 100 records? What's one request? A request for one batch? I would execute one batch in one thread.

How to parse multiple xml documents from single buffer

Hello,
I am trying to use jaxb 2.0 to parse a buffer which contains multiple xml documents. However, it seems that it is meant to only parse a single document at a time and throws an exception when it gets to the 2nd document.
Is there a way I can tell jaxb to only parse the first complete document and not fetch the next one out of the buffer? Or what is the most efficient way to separate the buffer into two documents without parsing it manually. If I have to search the buffer for the next document root and then split the buffer, it seems like that defeats the purpose of using jaxb as the parser.
I am using the Unmarshaller.unmarshall method and the exception I am getting is:
org.xml.sax.SAXParseException: Illegal character at end of document, <.]

Thank you for your help

It's just like any other XML parser, it's only designed to parse one XML document. If you have something that concatenates two XML documents together (that's what your "buffer" sounds like), then stop doing that.

How to parse an XML document with oracle8i

Has anyone a good link or an example how to decode and store an XML document into an oracle8i database.
I' ve found only good things for oracle9i.
Thank you
Roger

Here is an example of parsing xml taken fro Oracle8i 8.1.7 xdk.
This one uses external OS files to pase, but could be easily converted to
use CLOB or VARCHAR2 string for parsing XML documents.
IF you wanted to use CLOB to store and manipulate xml documents you can use XMLParser and XMLDom
packages along with the DBMS_LOB package to do that.

-- The XML file that is given to the application is parsed and the

Parsing String XML Document

I didn't find a method that parses a XML document when it's not a file. I have a String that I want to parse and the method DocumentBuilder.parse only accepts a String that is a uri to a file.
I write this code:
String strXML = "<?xml version='1.0' ?><root><node>anything</node></root>";
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
domDoc = docBuilder.parse(strXML);

My Task is To Parse a XML Document to Return CLOB's

Hi folks
I am writing this mail in the hope of getting a help.Please
give me a shoulder to keep me going.
The task is to parse a XML document for a specific Tag and
read the Tag content in CLOB to return CLOB.
I know that the writetoclob will do the job as
per oracle documentation.
I am giving the code where i got stuck.
Please help me complete my rest of coding.
Thanks
Input variables are
XMLin in CLOB, -- Incoming XML Document Structure
Partype in varchar2, -- Tagname
Result out CLOB -- Return Tag value CLOB data type.
My Code : -
Declare
p xmlparser.parser;
d xmldom.DOMDocument;
e xmldom.DOMElement;
nl xmldom.DOMNodeList;
n xmldom.DOMNode;
tagvalue varchar2(255);
paramsIn Clob;
result CLOB;
BEGIN
--loading SecXML
dbms_lob.createtemporary(paramsIn,true);
dbms_lob.append(paramsIn,XMLin);
--dbms_output.put_line('ParsebyTag ='||Partype);
--defining parser
p := xmlparser.newparser;
xmlparser.parseClob(p,paramsIn);
d := xmlparser.getDocument(p);
--get tagvalue
nl := xmldom.getElementsByTagName(d,partype);
n := xmldom.item(nl,0);
IF xmldom.getlength (nl) > 0
THEN
n := xmldom.item (nl, 0);
=>=>=> => xmldom.writetoclob (n, result); <=<=<=<=<=<=====
END IF;
return; -- from a procedure
The above line marked with a arrow does not work for CLOB Variables.
Please explain with a corrected code to complete this task.
Thanks for reading my request.
Please reply to this message poster as i am frequently

First, you have 2 variables with the same name,
Second, let me show you what is that you need to do:
PROCEDURE WriteDataToClob(XMLin in CLOB, Partype in varchar2, Result out CLOB) IS
Declare
p xmlparser.parser;
d xmldom.DOMDocument;
e xmldom.DOMElement;
nl xmldom.DOMNodeList;
n xmldom.DOMNode;
tagvalue varchar2(255);
TempClob Clob;
BEGIN
--Create a temporary clob
dbms_lob.createtemporary(TempClob,true);
--loading SecXML
--defining parser
p := xmlparser.newparser;
xmlparser.parseClob(p,XMLin);
d := xmlparser.getDocument(p);
--get tagvalue
nl := xmldom.getElementsByTagName(d,partype);
n := xmldom.item(nl,0);
IF xmldom.getlength (nl) > 0 THEN
n := xmldom.item (nl, 0);
xmldom.writetoclob (n, TempClob );
END IF;
Result := TempClob;
dbms_lob.FreeTemporary(TempClob);
END;

Storing a portion of XML document as a CLOB

Here is an example of what I am trying to do:
<ROWSET>
<ROW>
<COLUMN1>123</COLUMN1>
<COLUMN2>456</COLUMN2>
<COLUMN3>
<PARAMETERS>
<PARAMETER1>1</PARAMETER1>
<PARAMETER2>2</PARAMETER2>
</PARAMETERS>
</COLUMN3>
</ROW>
</ROWSET>
There is a table with 3 columns (column1 VARCHAR2, column2 VARCHAR2, column3 CLOB). I'd like to put everything enlosed in COLUMN3 tag in "column3" db column which is a CLOB, i.e. without any formating. Does anyone have suggestions on how to accomplish this? Currenly the CLOB column remains empty (?) with other columns getting the data and there are no errors and I am setting the "CLOB" column for update.
thanks,
vadim

Seems like I am replying to my own questions here. I thought storing a portion of XML document in as a clob was something many people had done or would be doing. In any case, the solution I found is to comment out the block that needs to be stored. In the example above, everything under COLUMN3 element should be surrounded by  tags. One can add these using XSL. Even though it works, it has a taste of a hack and I would appreciate comments about the right way to accomplish my task.
Thanks,

How do I parse a XML document?

Hello
I have a problem parsing a XML-document like the one below: Can anyone help me with a code example or something to get the tag "<Name>" out so that I get the string "Example5" and "Example3" out.
Thnx for any help!

The XML file looks like this (but without the line in the beginning of each row):

</ThisExample>

Thnx :O)
Now it worx!
Just one more thing. Can I get the number of elements there is in a tag? I.e. how many "Document"'s there are in 1 "Group"? I need this because I have too loop through a "Group" and print the name of every "Document".
At the moment I'm doing it like below, but that is not a nice solution, and it realy does not work that well:
Jimmy
int i = 1;
do
node = org.apache.xpath.XPathAPI.selectSingleNode(doc, "/PosttoolControl/Group[position()=" + i + "]/Type");
if (node.getFirstChild().getNodeValue() != null)
type = node.getFirstChild().getNodeValue();
PostToolDocGroupeComboBox.addItem(type);
i++;
} while (node.getFirstChild().getNodeValue() != null);

Need to display this as
CD_Tiltle, CD_ARTIST, CD_COUNTRY, CD_COMPANY, CD_PRICE, CD_YEAR
Empire Burlesque, Bob Dylan,USA,Columbia,10.90,1985
and so on..
I do not want to hard code the tag names in the script.
current example is 2 level hierarchy XML can be many level till 10 max I assume
in that case the csv file field name will be like P1_P2_P3_NodeName as so on..
Thanks in advance
Prajesh

Thankfully, I have writtenscript for ths same $node_name="";
$node_value="";
$reader = [system.Xml.XmlReader]::Create($xmlfile)
while ($reader.Read())
while ($reader.Read())
if ($reader.IsStartElement())
$node_name += "," + $reader.Name.ToString();
if ($reader.Read())
$node_value += "," + $reader.Value.Trim();
Thanks and Regards, Prajesh Please use Marked as Answer if my post solved your problem and use Vote As Helpful if a post was useful.

Hi Rodrigo,
Do you use a specific "encoding" like UTF-8 or ISO-8859-1 in your Sender CC.
Try changing the Transfer mode to Binary instead of Text.
Also go through these links:-
http://help.sap.com/saphelp_nw2004s/helpdata/en/e3/94007075cae04f930cc4c034e411e1/content.htm
Invalid char in XML from inbound IDoc
Hope this provides a solution.
Regards.

Servlets and XML - How to Parse the XML Document?

I would like to create a servlet, which when accessed, will retrieve an
XML file remotely over the Internet, and parse it to the browser's
screen.
Can anyone point to example code that will help me along?
Thanks.

Problem in parsing huge XML document

Hi,
i am getting the problem when trying to parse xml doc. which contains data more then 1 lacs. using jaxp (i.e. NodeList). i get the execption outofmemory.

Which implementation of JAXP are you using? If it is a large file containing many of the same "documents", then consider using SAX as it is an event driven parser meaning it does not have to read the whole of the file before it can start processing it. Instead, it fires events when it sees the beginning and end of a "document" and also on completion of the elements. You can then create and destroy objects during the document processing stage which helps keep the memory consumption under control.
