Versioning xml and structure storage
Hi,
I have following sitiations:
a. I have registered XML schema
b. I have put XML resource (based on the schema) into repos and I get new instance of XMLType in generated table.
That is ok.
My question is:
If I put a new XML file as the same resource will I get a new instance of XMLType or
the previous XMLType will be updated automaticlly ?
I mean , Can I create many version of the same resource and keep only one instance of XMLType in the XML table ?
regards,
Cezary
Unless you enable versioning each update of the resource will update the corresponding row in the default table.

Version 11.3 - Update version.xml
Hello Guys,
i have a little question. We installed for a few months a local update server for Adobe Flash Player. Today i seen on the download center (http://get.adobe.com/de/flashplayer/) that version 11.3. available.
So i take a look on the version.xml (http://fpdownload.adobe.com/pub/flashplayer/update/current/sau/11/xml/version.xml) and there "newst" Version is 11.2.0.235.
So i already read the admin guide for 11.3 but there no new information for me.
Is that a problem of Adobe or must i change the path to a new version.xml?!
Regards,
DanielHello Gernot,
Please see this post for both an explanation and a link to a bug report where you can add your votes and comments.

I understand that you are in a slightly different environment with a local update server, but the update logic is currently the same.

Query about XMLTYPE column structured storage in Oracle Xml db
Dear All,
DB Version: Oracle 11g (11.2.0.3.0)
I have an table having one column as XMLTYPE with Structured storage.
CREATE TABLE Orders
Order_id NUMBER NOT NULL,
Order_etc VARCHAR2(100),
Order_desc XMLType NOT NULL
XMLTYPE Order_desc STORE AS OBJECT RELATIONAL XMLSCHEMA "http://localhost/public/xsd/order_desc_xsd.xsd" ELEMENT "OrderState";
I have then registered the XSD with XML Db schema which is required for Structured storage.
Before this table creation I had created a table (db_objects) of XMLTYPE and was able to use the below query to check for what all objects the XMLTYPE table got broken into when I registered its XSD.
SELECT column_name,
data_type
FROM user_tab_cols
WHERE table_name = 'DB_OBJECTS';
And used below query to look for data stored in Object-Relational structure for my table (DB_OBJECTS) created with XMLTYPE definition.
SELECT EXTRACTVALUE(xseq.column_value, '/THISROW/OWNER') AS owner
, EXTRACTVALUE(xseq.column_value, '/THISROW/OBJECT_NAME') AS object_name
, EXTRACTVALUE(xseq.column_value, '/THISROW/OBJECT_TYPE') AS object_type
, EXTRACTVALUE(xseq.column_value, '/THISROW/OBJECT_ID') AS object_id
, EXTRACTVALUE(xseq.column_value, '/THISROW/CREATED') AS created
FROM db_objects do
, TABLE(XMLSEQUENCE(EXTRACT(VALUE(do), '/ROWSET/THISROW'))) xseq
WHERE ROWNUM <= 10;
Now could someone let me know, how to find how the column (Order_desc) of XMLTYPE was broken down into further objects just like I did for the Table with XMLTYPE (as shown above)?
Many Thanks.First given that you are on 11.2, ExtractValue is deprecated and the documentation lists three options to use instead. Here is one option (untested)
SELECT owner, object_name, object_type, object_id, created
FROM db_objects do,
XMLTable('/ROWSET/THISROW'
PASSING do.object_value
COLUMNS
-- Set data types accordingly
owner VARCHAR2(20) PATH 'owner',
object_name VARCHAR2(20) PATH 'object_name',
object_type VARCHAR2(20) PATH 'object_type',
object_id VARCHAR2(20) PATH 'object_id',
created VARCHAR2(20) PATH 'created');
Second, why does column order matter? You are storing in an object relational method. As long as the XML is valid per the schema, the Oracle will be able to store the data and later retrieve it as well. How that data is stored is mostly Oracle internals and should not be touched as it can be changed from version to version. You can use schema annotation to control how Oracle maps and stores the XML, but nothing in there specifies column order that I am aware of.
It seems additional details are missing as to what you need the information for so that would help others answer your question. -
Loading XML Document into Structured Storage
HI Everybody,
I am confronted with a BUG in Oracle which is being fixed but will last a long time. I have a relatively complex Schema with manifold includes, imports and inheritances which I can register successfully. The object-relational table is also generated. But loading the instance document with INSERT INTO... fails due to severe internal error. I have not yet tried SQL*Loader, however.
Please, does anyone know a safe alternative method to parse and load? Structured storage is mandatory because I need to retrieve individual elements and attributes. Instance documents are big, ca. 20 MB.
Thanks, regards
Miklos HERBOLYHI,

XML document structures must start and end within the same entity
Hi there,
I'm working with a client/server application and using SaxParser for reading in xml. I get the SaxParserException: XML document structures must start and end within the same entity. I understand what that means, but it isn't applicable! The xml data being used is well-formed. I checked the well-formedness with Stylus Studio to make sure. Here's the data:
<?xml version='1.0' encoding='UTF-8'?>
<vcmessage>
<vcsource>3</vcsource>
<processevent>16</processevent>
<shape>
<llindex>0</llindex>
<shapetype>9</shapetype>
<shapeproperties>
<shapelocation>
<xcoord>54</xcoord>
<ycoord>184</ycoord>
</shapelocation>
<bounds>
<width>24</width>
<height>24</height>
</bounds>
<fgcolor>
<fgred>0</fgred>
<fggreen>0</fggreen>
<fgblue>0</fgblue>
</fgcolor>
<bgcolor>
<bgred>255</bgred>
<bggreen>255</bggreen>
<bgblue>255</bgblue>
</bgcolor>
<thickness>1</thickness>
<isfilled>false</isfilled>
</shapeproperties>
</shape>
</vcmessage>The parser generally stops around the </bgcolor> tag.
I'm using Eclypse as my IDE. I'm wondering if there's something wrong with it? Or maybe there's something wrong with the class I'm using for reading in the XML? Followng is the class.
Please advise,
Alan

so how can i fix this problem..??Hi Scott,
in SDIXML_DATA_TO_DOM you can only pass the name of root node, so you can not assign attribute xmlns to root node (<Data xmlns="ServiceNet">) ... unless you build the xml document from scratch (without SDIXML_DATA_TO_DOM)
when using your sample code (without sale) I get xml without <item>

10.1.2.3 app server, xml, and Module version="101020300" and upgrade=yes
We upgraded our app server from 10.1.2.2 to 10.1.2.3. I converted some of our Oracle Forms to xml before upgrading. I noticed the following "Module version" element and value? What version of Oracle Forms is this 10.1.0.2 , 10.1.2.2, or 10.1.2.3. When I add upgrade=yes on the compile line the fmb file dates do not change and the xml version tag stays the same in unix. Whenver I do this on windows the files dates of the fmbs do change, but the version tag also stays the same. Is it possible the 10.1.2.3 compiler uses 10.1.0.2 version for fmbs and knows there is nothing to change so it leaves the fmb untouched when upgrade=yes?
<?xml version = '1.0' encoding = 'UTF-8'?>
<Module version="101020300" xmlns="http://xmlns.oracle.com/Forms"> Edited by: Mark Reichman on Aug 18, 2010 1:33 PMAlthough the "upgrade" option does not throw an error, it really doesn't apply any longer. It was used historically to convert SqlForms to Forms Menu Modules. Here is the text from the Forms Online help for this option:
Upgrades modules from Oracle Forms 4.5, or from SQL*Menu 5.0, to an Oracle Forms menu module.You gain nothing from including "upgrade=yes" when you compile your 10.1.2 modules.
Regarding the Module version you see in the XML or FMT, this version represents the engine used to create the module and not the Forms version. This version will not necessarily line up with the Forms version to which you are accustom to viewing. This is more of an internal reference. Your form's modules will not change in any way when you patch from 10.1.2.0 to 10.1.2.2 to 10.1.2.3. This is why there is generally no need to recompile when you patch. The changes are made in our product and not your app. -
App Files Saved as XML and Working with New Versions
We work with app data in the form of array of large clusters and use LV Anything to XML conversion VIs to save to disk.
The problem is when new app versions are developed and changes are made to the cluster format; we want the customer to be able to open the old version saved XML file format.
Usually the saved cluster (in XML) has be changed by adding/removing a field or even changing the options of a ring control for example.
The app name and version is stored in the XML.
Question: Is there a way of easily working with XML file formats with slightly different fields?
In the past we have worked with the raw XML text by searching for fields which are different and modifying them accordingly so they are accepted by the new file format.
Any tips would be greatly appreciated.battler. wrote:
I have written a software name and version cluster to XML. How do you read the version field in the XML? Do you use string search? Is there a better way?
Yes, I use String Search (because it is near the beginning of the XML string). Depending on your XML "flavor", you should be able to uniquely-identify the Version information.
I'm interested in how best to work with XML. It seems cumbersome and prone to error to use string functions. Is there a way or best practice of reading the XML fields directly without converting to cluster?
XML is, after all, text with specific "tag" information, also text, identifying it. String functions are pretty much "the way to go", but except in rare circumstances, you shouldn't necessarily "roll your own", but should try to use the utilities that come with your XML package that "know" how to do the mapping between the XML representation of a LabVIEW variable (and its value) and the Variable itself.
Can you elaborate on these "mapping" and "reading/conversion" routines you're using? How do they work and what functions do they use?
An excellent question. There are at least three XML packages out there for LabVIEW -- the "native" LabVIEW package that NI provides, EasyXML from JKI Software (distributed using VIPM), and GXML, also on the LabVIEW Package network. I'm afraid that I'm slightly "abusing" XML, and have made some modifications to how I use EasyXML and GXML.
If you simply view an XML file in a "smart" editor, you'll see a series of text lines with Begin/End tags (like HTML). Depending on the XML "flavor", embedded between the tags are data that describe the LabVIEW variable type (e.g. Dbl, Cluster, Array, etc.) and also the value(s) of the Variable. The "ReadXML" (or similarly-named) function takes this description and (usually) returns a Variant that you can "turn into" the chosen variable (because you know the data type). [You may need to tell the Reader, in advance, the type of LabVIEW variable to expect so that it "knows when to stop reading"].
As to how they work, they just do String pattern matching and processing, usually of a pretty sophisticated level, but then you don't have to do the hard work yourself!
Why do you use Private Project library? Is your project based on OO?
The reason I used a Project Library with the "messy details" in the Private parts has nothing to do with OO, but rather with "data hiding". I actually developed this for my data processing routines. I had a set of routines that collected and analyzed the data (about 700 VIs). Let's call this Project "Version 1".
For Version 2, I basically added a dozen variables to the main Data Cluster (having over a hundred elements) that characterized the response. As this Cluster was in a Type Def, I didn't have to change my code very much to accomodate this new data format, so most of my VIs kept the same name, but were "different" because the underlying TypeDefs were different.
So I have a Version 1 program that can analyze Version 1 data, and a Version 2 program for Version 2 data. What I want is a Version-independent program that can look at the data, and then call for Version 1 or Version 2 analysis. By burying the Version 1 and Version 2 code inside of a Project Library, and only exposing the top-level "Analyze My Data" VI, my Analysis routine, which didn't know (and didn't care) about the two different Data TypeDefs, just figures out (from the XML) which Version of data I have and then calls either Lib1:Analyze My Data or Lib2:Analyze My Data. If I ever change the Version again, I just need to copy the code in the Library to a new Lib3 Library, modify the TypeDef and related version-specific code as needed, and I'm done.
I may have made this sound easy -- trust me, it was a definite learning experience. While trying this out, the first thing I did was to "break" my installations of LabVIEW 2012, 2013, and 2014 (curiously, LabVIEW 2011 wasn't broken). It stayed "broken" for about a week, then "cured" itself (I'd done something illegal, or maybe just immoral, with my Library, and it took a while to purge the badness).

Moving pages using Manage Site content and structure is corrupting the version history
Hi,
I am using share point 2010 manage site content and structure feature to move pages from one sub site to other. After doing several edits and check ins of a page and if I try to move the page using manage site content and structure , the version history
is corrupted in the destination site (i.e., all the versions are not showing).
Note: Sometimes content is also getting replicated after performing move operation.
Is it a Bug/ Known issue in SharePoint?
Any info on this issue is very helpful to us.
Thanks in advance!!Hi,

I am loading an XML into flash which contains a carriage
return.
In Flash version 7+ this is no problem.
In version 6 any node with the carriage return Kills the XML
parse.
All other aspects of the swf work in version 6 and would like
to keep it in the that version.
Anybody have a solution for this?I suppose you could strip out the CRs before they get to the
parser. See

Versions and excessive storage concerns
Doesn anyone know if Versions creats the same storage issues that iPhoto does? The iPhoto libraries are massive as they don't use pointers to the original files, they create their own libraray. Most programs that keep versions do a similar thing in that it save numerous verisons of the file you are working on so that you can go bak in time to pull an old one. This in turn would create a data hog on your HD. My big question is can you turn off Versions or is it live all the time. If it cannot be turned off I will NOT be upgrading to Lion. I await any responses that are "in the know"
--BrianI'm not sure I fully understand the question, but I believe that there is only one copy of each song on the iphone which can be accessed various ways (songs, albums, artist, shuffle, etc.).

Structured storage XMLType but disappointing performance
Hi,
This relates to Oracle 11g, but maybe the same question can be asked for 10g.
I'm having a lot of big XML files which are structured following this xsd:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xs:schema
xmlns="http://localhost/public/xsd/simple.xsd"
targetNamespace="http://localhost/public/xsd/simple.xsd"

<xs:complexType>
<xs:sequence>
<xs:element name="ea">
<xs:complexType>
<xs:sequence>
<xs:element name="eb" minOccurs="1" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="c1" type="xs:double" />
<xs:element name="c2" type="xs:double" />
<xs:element name="c3" type="xs:double" />
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>I create a VARRAY (the order is important) based structured storage table using the following commands:
declare
l_bfile bfile;
res boolean;
begin
l_bfile := bfilename('EXDIR', 'simple.xsd');
dbms_lob.open(l_bfile);
dbms_xdb.deleteResource('/public/simple.xsd',4);
res := dbms_xdb.createResource('/public/simple.xsd',l_bfile);
end;
BEGIN
DBMS_XMLSchema.deleteSchema(
schemaurl=>'http://localhost/public/xsd/simple.xsd',
delete_option=>DBMS_XMLSchema.Delete_Cascade_Force);
END;
begin
dbms_xmlschema.registerSchema(schemaurl => 'http://localhost/public/xsd/simple.xsd',
schemadoc => xdbUriType('/public/simple.xsd').getXML(),
local => true,
gentypes => true,
genbean => false,
gentables => true,
force => false,
owner => user);
end;
CREATE TABLE simple_or_1 OF XMLType
XMLSCHEMA "http://localhost/public/xsd/simple.xsd"
ELEMENT "root"
VARRAY "XMLDATA"."ea"."eb"
STORE AS TABLE simple_nested1
((PRIMARY KEY (NESTED_TABLE_ID, SYS_NC_ARRAY_INDEX$)))
/And I load some XML files of the following form:
<?xml version="1.0" encoding="UTF-8"?>
<root xmlns="http://localhost/public/xsd/simple.xsd">
<ea>
<eb>
<c1>4.0</c1>
<c2>5.0</c2>
<c3>6.0</c3>
</eb>
<eb>
<c1>7.0</c1>
<c2>8.0</c2>
<c3>9.0</c3>
</eb>
<eb>
<c1>7.0</c1>
... etc ...
</ea>
</root>
Every document has about 50.000 <eb> elements and I loaded 6 sample documents.
A simple query like the following takes about 5 minutes:
SELECT XMLQuery('
declare default element namespace "http://localhost/public/xsd/simple.xsd"; (: :)
for $i in /root
return max($i/a/b/c2)

3 - access("NESTED_TABLE_ID"=:B1)I'm not understanding the low performance of 5 minutes... is there anyone who can explain and help out?Note with DOM Fidelity disabled on all types the SYS_XMLCONV is replaced with the more efficeint SYS_XMLGEN. However this is still not as efficient as the XMLTable approach..

Hi,
Thanks in advance for reading this.
I am new to this XML and import into database.
I have the xml file, i need to import this into database and search on the database.
I have around 2.2 million records in the database.
Please explain me what is best method of storing in database, like store the file in clob column and search on the clob column.How the search is going to be on 2.2 million records.
Please send me any if any sample code you have to [email protected]The answer on this question also depends on the version of the database you are using.
With 9i/10g i would probably use structured storage of XML (based on the XMLschema).
But the answer also depends on another question: does the XML document contains "2.2 million records" or will you be storing 2.2 million XML documents? -
Piecewise Insert into structured storage
I understand that XMLUPDATE can handle piecewise update, but what do I do for piecewise insert. I want to add a sub-tree (document fragment) conformant with the registered schema to the xml document, without re-writing the whole (possibly very, very large and growing) document, and retaining all the power and abstraction of structured storage.
It would be nice to get an XMLType via an XPath select, get the DOM object from the XMLTYpe, operate on the DOM, and see those changes reflected in the database. I can do all that, but the changes to the DOM seem to be in-memory only.
How do I add a sub-node to an existing structured document?
Thanks,
DavidHI,
