Query language for XML documents

Which is a better (efficiency in terms of memory management) query language for interacting with XML documents.The query language shouls support 'insert', 'delete', 'update' and 'select' commands. How fast is database as compared to XML ( database being replaced by XML) when only 'insert' n 'select' commands are issued?

Hi,
I suggest you use the Sunopsis JDBC for XML driver that will let you perform all kind of SQL statements on your XML files. It is a type 4 driver so it's very use to use. You may have more information and download it here:

Hope that will help

Query language for XML that is going to remove use of database

Friends,
I want to know whether my idea is feasible or not.
I want to make a query language similar to SQL for XML which is going to remove the need for database for a large extent.
Their will be queries for making table,extracting data,making foreign key all through XML and no database.
I just want to know that is their any market value for such a project and will it be sellable,so that i can start working on it.

There is no way to judge any future market for such a thing.
As it is, XML is widely abused, having mutated from its original purpose, a markup language readable by both machine and human, to a general data interchange language. It winds up being extremely slow and convoluted, in some cases overwhelming the hardware when a simple and common error occurs, then having to catch up. A big part of this is the silly and redundant method of defining metadata, again and again and again and again.
So what you want to do is create a database which will be highly formatted with redundant information, dynamically. This is silly, why does data need to be stored in a human readable format? It doesn't always even need to be presented in a human readable format! Why the heck would you need to read the bits of an mp4? Steganography?
What you are proposing is the exact opposite of what is needed. What is needed is a way to describe metadata for many different kinds of data, in a manner that can be interpreted by both man and machine at appropriate times, extensible for various paradigms.
What can be sold, on the other hand, is another question entirely, and not technical at all.
First definition of database that pops up during a search: an organized body of related information
Why would you want to get rid of that?

Indices configuration for XML document analysis (indexing time problems)

Hi all,
I'm currently developing a tool for XML Document analysis using XQuery. We have a need to analyse the content of a large CMS dump, so I am adding all documents to a berkeley DB xml to be able to run xqueries against it.
In my last run I've been running to indexing speed problems, with single documents (typically 10-20 K in size) taking around 20 sec to be added to the database after 6000 documents (I've got around 20000 in total). The time needed for adding docs to the database drops with the number of documents.
I suspect my index configuration to be the reason for this performance drop. Indeed, I've been very generous with indexes, as we have to analyse the data and don't know the structure in advance.
Currently my index configuration includes:
- 2 default indicess: edge-element-presence-none and edge-attribute-presence-none to be able to speed up every possible xquery to analyse data patterns: ex. collection()//table//p[contains(.,'help')]
- 8 edge-attribute-substring-string indices on attributes we use often (id, value, name, ...)
- 1 edge-element-substring-string index on the root element of the xml documents to be able to speed up document searches: ex. collection()//page[contains(.,'help')]
So here my questions:
- Are there any possible performance optimisations in Database config (not index config)? I only set the following:
setTransactional(false);
envConf.setCacheSize(1024*64);
envConf.setCacheMax(1024*256);
- How can I test various index configuration on the fly? Are there any db tools that allow to set/remove indexes?
- Is my index config suspect? ;-)
Greetings,
Nils

Hi Nils,
The edge-element-substring-string index on the document element is almost certainly the cause of the slow document inserts - that's really not a good idea. Substring indexes are used to optimize "=", contains(), starts-with() and ends-with() when they are applied to the named element that has the substring index, so I don't think that index will do what you want it to.

When using Exprt PDF, the choice of language for the document to be exported is sometimes very restricted, while sometimes many more languages are available. What's the matter?

When using Exprt PDF, the choice of language for the document to be exported is sometimes very restricted, while sometimes many more languages are available. What's the matter?

Dear Mrs.,
I now add 2 print screens which show what I get when I try to export a PDF from Adobe Reader and which languages are available.
The same problem does not exist when I use the website.
I hope this gives you a clue.
Many thanks,

Query language for CTXRULE MATCHES

I am trying to build an alerting application when, on receipt of a new XML document, user's are alerted if the document matches one or more of the profiles that they have defined. I have created a CTXRULE index that does this but only with very simple profiles. For example ABOUT(soccer), which is the example in the Text documentation.
Is it possible to create more complex queries, for example using WITHIN to only match within defined elements of the XML document. Is there a definition of the query language that can be used with MATCHES and are there any good example?
Thanks
Martin Haigh

Omar,
Thanks for the reply. I had actually found that document myself but I couldn't get the WITHIN clause to work and that document conflicted with the ORACLE documentation at:
<a href="http://download-west.oracle.com/docs/cd/B10501_01/text.920/a96517/ind.htm#1010647> Do you have any examples of using WITHIN?
Thanks
Martin

How do i query attributes from xml documents

I tried to extract value for R_DATE & R_REVIEW_DATE for issue id=705230, but iam not able to.
Data for all the issues is retured.
Here is the query used...

I did not include the name space declaration for it is working fine. Really? Then I suppose you must be using a schema-based XMLType column?
Is it Object-Relational or Binary XML storage?
You mentioned it is depricated in 11.2, but iam able to run it on 11.2.Deprecated doesn't mean it ceases functioning.
Any suggestions to covert this to XMLTable/XMLQuery format please..If you read the documentation, it covers this part too ;)
Example :
create table tmp_xml of xmltype;
insert into tmp_xml values(
xmltype('<ns1:PcrDocument id="PCR-13562" title="EU Disclosures - EC 1060/2009" version="1" pcrPublishDate="2012-01-11T12:49:02" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ns1="http://integration.mysite.com/ServiceSchema/v3">

Templates for XML documents in Dreamweaver CS3?

I have a strange question. Is it possible to create a DW
template (.dwt) for an XML document with editable and repeatable
regions? I would like to set up some templates that will allow my
users to create new XML files and edit the appropriate regions with
Contribute.
Any advice would be greatly appreciated.

Document type definitions for xml documents exported from SBO?

I am looking for DTD or XSD specifications for the documents that are exported from SBO via the DI API. It seems that this information is not available with the standard DI API documentation. Does anyone have a clue about where to look for these specifications ?
Best regards,
Henry Nordströ

The DI Company object has a GetBusinessObjectXmlSchema method which allows you to retreive the schema details.
Below is the sample from the DI help file.
Dim XMLStr As String
Dim domDoc As DOMDocument
Set domDoc = New DOMDocument
XMLStr = vCmp.GetBusinessObjectXmlSchema(oInvoices)
domDoc.loadXML (XMLStr)
domDoc.save ("C:\ XMLFiles \MyXML2.xml")

John.

Query regarding FOR XML PATH

I have found a script that contains the following:
stuff(
select
', ' +
fielda
from
tablea
for
xml path (''),
type).value
'nvarchar(max)')
,1,2,
anotherfield
This will concatenate field a and the stuff will remove the leading comma.
I have amended the script to the following and it still works:
Stuff(
select
', ' +
fielda
from
tablea
for
xml path (''))
,1,2,
Afield,
Please could somebody tell me why the following has been inserted after the
for xml path ('')
section
type).value
('.', 'nvarchar(max)')

Erland - I just did a quick test. The differences weren't as bad as the subtree estimates would have indicated but they weren't exactly close either. The typed version (on average) took just over twice as long to execute.
Test conditions were as follows:
AdventureWorks2012 database
On average, the non-typed version executed in ~190 ms and the typed version executes in ~405 ms.
Test bed was the following:
@@VERSION =
Microsoft SQL Server 2012 - 11.0.2218.0 (X64)

Ram: 16.0 GB @ 2400 MHz

Here are the two test scripts that I used... (each run in it own SSMS tab)
-- Typed version --
DECLARE @BegDT DATETIME2(7) = SYSDATETIME()
SELECT
sod1.SalesOrderID,
STUFF((
SELECT ', ' + CAST(sod2.ProductID AS VARCHAR(8))
FROM Sales.SalesOrderDetail sod2
WHERE sod1.SalesOrderID = sod2.SalesOrderID
FOR XML PATH(''), TYPE).value('.', 'varchar(max)'), 1, 2, '') AS csv
FROM
Sales.SalesOrderDetail sod1
GROUP BY
sod1.SalesOrderID
SELECT DATEDIFF(ms, @BegDT, SYSDATETIME()) AS ExecTimeMS
-- Non-typed version --
DECLARE @BegDT DATETIME2(7) = SYSDATETIME()
SELECT
sod1.SalesOrderID,
STUFF((
SELECT ', ' + CAST(sod2.ProductID AS VARCHAR(8))
FROM Sales.SalesOrderDetail sod2
WHERE sod1.SalesOrderID = sod2.SalesOrderID
FOR XML PATH('')), 1, 2, '') AS csv
FROM
Sales.SalesOrderDetail sod1
GROUP BY
sod1.SalesOrderID
SELECT DATEDIFF(ms, @BegDT, SYSDATETIME()) AS ExecTimeMS
If you see holes in my test approach, please let me know.

Hey Guys, I am querying a DB with huge amount of traffic. A user select a particular lot and then details of the lot will be displayed in the following page. My concern here is that it takes really LONG to retrieve back the results coz it has to requiry in the following JSP page.
I was told to use XML to retrieve the dataset and store it. Hence, in the following query it will re-query only from the recordsets in the XML file (...Logically, should be faster rite ? )
My question is how do I go about doing this ? Any sort of suggestion , help, reference would be deeply appreciated ..Thanks !

Why not take the result set and populate zero or more Java objects with data from each row in the result set? Then you can easily sort the data by putting the objects into a collection and using different Comparator objects for your sort. I'm just not sure why you want to use XML if the data isn't getting transfered between systems. In my experience XML is best used when you need a readable content for something (such as a properties file) or you want to share data between systems. I might be missing something, but I think you are better off storing your data in java and sorting it there.

Using Content Query webpart for specific Document library with multiple managed metadata - Document with multiple metadata tags not showing up

Hi,
I am having an issue where when I insert a Content Query webpart into a page, and filter to managed metadata, all the right documents show up except one document that happens to have two metadata tags attached to it. The content query webpart is set
to only look through a specific document library. I'm not sure what I am doing wrong.
Here is the one document with two metadata tags:
Below is the Content Query:

Hi,
As I understand, you did not get the results with multiple metadata tags through Content Query web part in SharePoint 2013.
Check things below:
1. Check if you have set the item limit more than the display items in Presentation section of the web part. If the item number more than item limit, the rest items will not show.
2. Check if the item you cannot find uses the content type you have set in the content type section of content query web part.
When you edit the properties of the item, you will see the content type the item is using.

Specifiying Language for Document Properties if PDF Form

In order for a pdf to be 508 compliant it's language must be specified. I've created a form and for the life of me can't figure out how to specify the language for this document such that Adobe Reader knows it's english. In a pdf NOT created using lifecyle this would be easy. simply go to file > properties> advanced > Language > english. but in pdf forms that section of the properties is greyed out. I tried adding it to the xml like this: <text name="Language">English</text> in the <desc> tag. Please if you have ANY suggestions they'd be much appreciated.

I wonder if you have seen the form being filled, or a screen shot, so can confirm that Adobe Reader is the app when it is filled? (And not Adobe Reader Touch or a browser or Microsoft Reader or any other app). The reason for asking is that many users (not unreasonably but wrongly) assume that once Adobe Reader is installed it is bound to be used.

How to extract the nodes of any given XML document ???

Hello,
Greetings! It is an interesting forum.
A Snippet of XML Schema PurchaseOrder.xsd as given in user guide is as follows
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xdb="http://xmlns.oracle.com/xdb"
version="1.0" xdb:storeVarrayAsTable="true">
<xs:element name="PurchaseOrder" type="PurchaseOrderType"
xdb:defaultTable="PURCHASEORDER"/>

The views use XPath expressions and functions such as extractValue() to define the mapping between columns in the view and nodes in the XML document. The following view is created on purchase order schema.
Creating Relational Views On XML Content
CREATE OR REPLACE view PURCHASEORDER_MASTER_VIEW
(REFERENCE, REQUESTOR, USERID, COSTCENTER,
SHIP_TO_NAME,SHIP_TO_ADDRESS, SHIP_TO_PHONE,
INSTRUCTIONS)
AS
SELECT extractValue(value(p),'/PurchaseOrder/Reference'),
extractValue(value(p),'/PurchaseOrder/Requestor'),
extractValue(value(p),'/PurchaseOrder/User'),
extractValue(value(p),'/PurchaseOrder/CostCenter'),
extractValue(value(p),'/PurchaseOrder/ShippingInstructions/name'),
extractValue(value(p),'/PurchaseOrder/ShippingInstructions/address'),
extractValue(value(p),'/PurchaseOrder/ShippingInstructions/telephone'),
extractValue(value(p),'/PurchaseOrder/SpecialInstructions')
FROM PURCHASEORDER p;
When we register XML Schema in Oracle 9i, the schema elements of XML documents are stored as XMLType, that is, stored using object-relational storage techniques.
For a small schema, we could build the above view manually, but for large/nested schema, if we have query to build XML documents node list, it will help us to build Relational Views on XML Content.
How do we extract the nodes of any given XML document through O-R structures or XML DB using XML DB functions?
Any alternate thoughts are welcome.
I appreciate your help.

Once again, I do not think that you can solve the problem you are trying to solve. Fundamentally you need to determine for a given element of a given complex type what are it's child elements. For each of those elements you then need to find out whether or not it in turn has child elements...
Then you have to think about elements defined as ref rather than type, elements that are substituteable, and the rest of possibilities that can be described with XML Schema.
If you can solve that problem you're a better man than I as the saying goes. Anyone rather than give you a fish, I'll show you how to at least put a worm on the hook..
The following query gets the names of the elements inside a each of the global complex types
Good luck, if you come up with a query to do this I'd love to see it...

Generating mixed case columns for XML using Object views

I am trying to model a query involving joins to generate hierarchical levels for XML document. I model it with an object view with a multicast subquery and the generated XML works fine except the following :
The generated XML creates a tag <view_column_name>_ITEM for the nested multicase subquery columns in the view and all the nested subquery view columns in upper case because the underlying table columns are in upper case. To better illustrate, please see the following example :
CREATE TYPE Tillinstance_t as object (
"Tillinstanceid" number
,"Stationid" number
,"Comment" varchar2(2000)
,"DepositID" number(38)
,"TimestampCreate" date
,"UseridCreate" number
,"TimestampChange" date
,"UseridChange" number
,"TimestampClosed" date
,"UseridClosed" number
,"TimestampBalance" date
,"UserIDBalance" number )
create type insts as table of Tillinstance_t ;
CREATE OR REPLACE VIEW till_view AS
SELECT t.tillid as "TillID"
, t.description as "Descr"
, t.word as "Word"
, t.Scopetypeid as "ScopeTypeId"
, t.displayOrder as "DisplayOrder"
, t.useridcreate as "UserIDCreate"
, t.newid as "NewID"
, t.flagactive as "FlagActive"
, t.timestampcreate as "TSCR"
, t.useridcreate as "UIDCR"
, t.timestampchange as "TSCH"
, t.useridchange as "UIDCH"
, CAST( MULTISET ( SELECT i.Tillinstanceid as "TillinstanceID"
, i.stationid as "StationID"
, i.ocomment as "Comment"
, i.depositid as "DepositID"
, i.Timestampcreate as "TSCR"
, i.useridcreate as "UIDCR"
, i.Timestampchange as "TSCH"
, i.useridchange as "UIDCH"
, i.timestampclosed as "TSCL"
, i.useridclosed as "UIDCL"
, i.timestampbalance as "TSBAL"
, i.useridbalance as "UIDBAL"
FROM TillInstance i
WHERE t.tillid = i.tillid)
AS Insts)
AS "Insts"
FROM ucTill t
The generated XML shows up in the form of :
<?xml version = '1.0'?>
<Tills>
<Till TillID="1002" Descr="Till #3" Word="Till3" ScopeTypeId="8"
DisplayOrder="0" UserIDCreate="296" TSCR="3/26/2001 0:0:0" UIDCR="296"
TSCH="5/4/2001 14:12:32" UIDCH="298">
<Insts>
<Insts_ITEM TILLINSTANCEID="1278" STATIONID="1057" OCOMMENT="Morning Till3"
TIMESTAMPCREATE="3/26/2001 0:0:0" USERIDCREATE="296" TIMESTAMPCHANGE="6/7/2001
8:26:49" USERIDCHANGE="99" TIMESTAMPCLOSED="6/7/2001 8:26:49"
USERIDCLOSED="99"/>
<Insts_ITEM TILLINSTANCEID="1362" STATIONID="1057" TIMESTAMPCREATE="6/7/2001
8:27:13" USERIDCREATE="99" TIMESTAMPCHANGE="6/11/2001 11:32:58"
USERIDCHANGE="320"/>
</Insts>
</Till>
</Tills>
Now How do I stripe out the _ITEM from the generated XML and change the columns TIMESTAMPCREATE, USERIDCLOSED etc to mixed case?
Any idea

I could generate the mixed case columns with no problem. It was my mistake and sorry for the inconvinience.
However I am running into problems modelling a nested hierarchical set of queries with levels more than 2.
Please advise of any sample code available anywhere.
For example I could do :
create table x1 ( id number , f1 varchar2(10));
creat table x2 ( id number , id_x1 number references x1(id) , f1 varchar2(10)) ;
create table x3 ( id number , id_x2 number references x2(id), f1 varchar2(10)) ;
To model this, I did
create type x3_typ as object ( id number, id_x2 number , f1 varchar2(10)) ;
create type x3_typ_t is table of x3_typ ;
create type x2_typ as object ( id number, id_x1 number , f1 varchar2(10), x3_list x3_typ_t ) ;
create type x2_typ_t is table of ref x2_typ ;
create type x1_typ as object ( id number
, f1 varchar2(10) , x2_list x2_typ_t ) ;
create or replace view x3_x2 as
select id , f1 , cast(multiset(select * from x3 ) as x3_typ_t ) as x3_list
If I try to use a view again like as given below, I get the Oracle inconsistent datatypes error.
create or replace view x2_x1 as
select id , f1 , cast(multiset(select * from x3_x2 ) as x2_typ_t ) as x2_list
I there a better way? Am I missing something? Please help.
