Xml Validation & XQuery Update
Hello,
I have a question on xml validation in Berkeley DB XML (2.5.16).
I read in documentation that an xml can be validated against an xml DTD or Schema when is loaded into a container. However, when an XQuery Update is to be executed is there any configuration that allows checking if the XQuery Update leads to an xml that does not conform with the DTD/Schema? If so, how this case is managed? The XQuery is executed, or not? Is there any exception thrown?
I made a test over this: I wrote an xml (and a related DTD) where an element contains an id attribute and another element a referencing attribute to the aforementioned id. Then, an XQuery Update 'delete' expression deletes the element with the id attribute. The element is indeed deleted, the xml is left in an inconsistent state and I am allowed of making more update operations to this document...
I was wondering if there is any way of handling this case, except from being careful with what updates you choose, so that the xml is kept in a valid state. Is there something I am missing?
thank you in advance,
theo
Hello,
I believe that XQuery execution does not support DTD yet. I'll investigate further and let you know what else I can find.
Thanks,

Hi everybody,
Certainly my question will appear strange and even stupid , but I want to be sure to use the best syntax and also to be confirmed about some points.
In the document Oracle XML DB Best practices, we can find a lot of statements for modifying XML documents. In page 11 and 12 we have statements with and without XQuery syntax. What is exactly the best way ? Using insertchildxml, updatexml or the update statement with the XMLQuery clause ?
Why we use copy in these statement, but the keyword copy is not used in a XQuery expression.
I think copy is not specific to Oracle, is it used in XQuery language ?
In page 15, the SQL statement to modify XML document uses deletexml, not a XQuery update syntax.
I'm using Oracle 11G.

"11g" is not a version, it's a product name.
You can find the version by running :
SQL> select * from v$version;
BANNER
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production

NLSRTL Version 11.2.0.3.0 - Production
XQuery Update on Oracle in available in the latest version only : 11.2.0.3.
If you're using this version, Oracle recommends you start using XQuery Update.
Why we use copy in these statement, but the keyword copy is not used in a XQuery expression.
I think copy is not specific to Oracle, is it used in XQuery language ?<tt>copy</tt> is specific to the XQuery Update Facility (XQUF) extension of the XQuery 1.0 language.
The XQUF was primarily intended to work with native XML databases where it's OK to directly invoke update primitives (insert, delete, replace etc.) to modify database content.
On Oracle, it's not possible and the current implementation only supports XQUF through the "transform" operation (copy/modify syntax) where a copy of the original document/fragment is modified and written back to the db.
However, XQuery rewrite and related optimizations may occur so that piecewise updates actually take place. -
Hello,
I seems that the CVS version of XQuilla implements a large part of the XQuery Update working draft, which is great !
Does it mean that it's usable with BDB XML as-is to get database updates ?
Thanks,
FabriceHi Fabrice,
I'm afraid there is significant work to do in DB XML before XQuery Update can be used from it. However, It is our intention to support XQuery Update in some future version.

Dear all,
I am looking for some database systems that use the W3C XQuery Update facility specification to modify their data.
To the best of my knowledge, no of well-known commercial database systems uses XQuery Update primitives.
For instance, Oracle 11g defines some SQL/XML update functions (combined with some XQuery expressions) to modify XML data stored within the database through the XMLType data type.
IBM DB2 9 uses SQL update statement to modify the whole XML document stored as an XML column and no update is proposed to modify parts of the document.
Are there some database systems providing XQuery-Update-Facility-based update of their data.
Thank you in advance.
Best regards.Were you aware of
[url http://www.liberidu.com/blog/2011/09/22/oracle-xmldb-xquery-update-in-database-release-11-2-0-3-0/]Oracle XMLDB XQuery Update in Database Release 11.2.0.3.0
Given it is new, expect a few bugs, such as

Regarding error in xml validation in 7.1
Hi
I am getting following error in xml validation in 7.1
my scenario is IDOC TO FILE
from idoc DATE_TIME field comes with 14 digits. In the target I created DATE_TYPE field with data type
"dateTime" and in details column pattern section I mentioned yyyyMMddHHmmss.while doing xml validation in I am gettting this error:(xml validation done in receiver agreement validation by Integrtion engine)
cvc-pattern-valid: Value '20080213081220' is not facet-valid with respect to pattern 'yyyyMMddHHmmss' for type 'null'
Please give me some inputs on this.
Regards
venkat.Hi,
try this - update your target msg xsd in your XI folder........rerun your scenario and see if this error is still there..........
if this error remains same, then in IR in data type, remove your pattern and just keep dateTime as datatype.......again update your xsd in XI folder.........rerun your scenario.

XQuery Update Facility in XMLDB?
Hi
I didn't find information about XQuery Update Facility
support or XUpdate support in Oracle XML DB. Do you have
such info?
Regards,
--drkmXquery update is NOT anywhere near well enougth defined for us to implement it at present. We are actively involved in the standards process for XQuery update. It's very unclear what the future of the XUpdate is at this point...
We support node-level updates through a set of SQL functions
updateXML (9iR2 and later), insertChildXML, appendChildXML, insertXMLBefore and deleteXML (10gr2 and later)

Decreasing performance when executing consecutive XQuery Update operations
hello,
I am writing an application in java using Berkeley DB XML (2.5.16). I have to run a test over the application, in which a lot of XQuery Update operations have to be executed. All update operations are insert statements. In the beginning the test works fine. However, as the number of updates increases (over 1000 XQuery Updates), there is also a great increase in time of execution. How can I enhance the performance of updates?
Note that:
1) The environment configuration is the following:
EnvironmentConfig envConfig = new EnvironmentConfig();
envConfig.setAllowCreate(true);
envConfig.setInitializeCache(true);
envConfig.setCacheSize(512*1024*1024);
envConfig.setInitializeLocking(false);
envConfig.setInitializeLogging(false);
envConfig.setTransactional(false);
2) No transactions are used
3) The container is a node container
4) Auto-indexing is on (I need that)
5) The container includes only one xml of 2,5MB size.
6) In some insert statements 1000 nodes are to be inserted.
7) I am running windows vista on a 4GB Ram pc.
Thank you in advance,
theoHi Lucas,
Thanks a lot for your reply! However, I have a few more questions.
Given that the xml is about 2.5MB size, is it considered to be that big for Berkeley DB so it needs to be break down into smaller documents?
Also, after having executed ~4000 xquery update insert operations and doubled xml’s size, the performance it’s really getting worse… An insertion may even take 1.5 min, when for each of the first 3000 insertions only less than 0.5 sec is needed… Is there something I am missing in the configuration of Berkeley DB? If I set autoindexing off and try to maintain fewer indexes, is it possible to see significantly better performance? Till now I am just getting the following error when I set my indexes and try to execute consequent insertions over the same node:
Exception in thread "main" com.sleepycat.dbxml.XmlException: Error: Sequence does not match type item() - the sequence does not contain items [err:XUDY0027], <query>:1:1, errcode = QUERY_EVALUATION_ERROR+

XQuery Update (11.2.0.3) and the path table
Hi,
I'm currently using XQuery update on 11.2.0.3 to merge 2 XML documents, having tried a number of approaches up to now on 11.2.0.2.
My table has one XMLType column (securefile binary containing unstructured xml) which has XML deltas applied to it via a stored procedure.
An unstructured XML index is defined on the column.
Previously, I was doing the following:
1) Merge documents using XMLQuery; only produce a merged document if changes were detected
2) Update the table if the merged document is non-null
i.e.
select XMLQuery(<merging code>) passing oldDoc as "oldDoc", delta as "delta" returning content) into mergedDoc from dual;
if (mergedDoc is not null) then
update myTable set xmlDoc = mergedDoc where id=v_id;
end if;However, this replaces the entire document if any changes are detected (with an obvious impact on the path table).
I then read (UpdateXML query rewrite with unstructured data? about the use of XQuery Update in 11.2.0.3 to only target the affected document fragments so my current approach is:
update myTable
set xmldoc =
xmlquery('declare namespace m="http://www.blah.com/merge";
(: See if two nodes have matching text (or no text which is an empty sequence :)
declare function m:matchText($one as element(), $two as element()) as xs:boolean {
if ($one/text() = $two/text() or count($one/text())=0 and count($two/text())=0) then true() else false()
declare updating function m:merge($old as element()?, $new as element()?) {
(for $o in $old/* return
for $n in $new/* where name($o) = name($n) return
if (count($n/*) > 0) then
m:merge($o, $n)
else
if (m:matchText($n, $o)) then () else replace value of node $o with $n,
for $n in $new/* where (not(some $o in $old/* satisfies name($o) = name($n))) return insert node $n into $old)
copy $d := .
modify (
(m:merge($d/*,$delta/*))
) return $d'
passing xmldoc, delta as "delta"
returning content)
where id = v_id;If no changes were detected between the documents (i.e. the XQuery update did not actually modify the document), would you expect this statement to have no impact on the path table? Is there any way to get more trace information which shows what the update is actually doing when it executes?
Apologies if this is overlong or if I have omitted any supplementary information.
Thanks for any assistance
LarryHi,
many thanks for your reply.
A simple testcase is below. The recursive approach is required because the documents may be hierarchial.
create table mytable (id number(19,0), xmldoc xmltype) xmltype column "XMLDOC" store as securefile binary xml;
insert into myTable values (1,xmltype('<xml><el1>1</el1><el2>2</el2><el3>3</el3></xml>'));
update myTable
set xmldoc =
xmlquery('declare namespace m="http://www.blah.com/merge";
(: See if two nodes have matching text (or no text which is an empty sequence :)
declare function m:matchText($one as element(), $two as element()) as xs:boolean {
if ($one/text() = $two/text() or count($one/text())=0 and count($two/text())=0) then true() else false()
declare updating function m:merge($old as element()?, $new as element()?) {
(for $o in $old/* return
for $n in $new/* where name($o) = name($n) return
if (count($n/*) > 0) then
m:merge($o, $n)
else
if (m:matchText($n, $o)) then () else replace value of node $o with $n,
for $n in $new/* where (not(some $o in $old/* satisfies name($o) = name($n))) return insert node $n into $old)
copy $d := .
modify (
(m:merge($d/*,$delta/*))
) return $d'
passing xmldoc, xmltype('<xml><el1>1-UPDATE</el1><el4>4</el4></xml>') as "delta"
returning content)
where id = 1;This results in one update and one insert:
<xml><el1>1-UPDATE</el1><el2>2</el2><el3>3</el3><el4>4</el4></xml>It currently produces the following trace:
*** 2012-03-13 10:13:34.708
not delete/insert/replace in modify clause
--------- XQuery NO rewrt expr END-----
--------- XQuery NO rewrt expr BEG-----
UDF with noderef
--------- XQuery NO rewrt expr END-----I've noticed that even with a simple XQuery update like the following:
update myTable set xmldoc =
xmlquery('copy $d := .
modify (
(replace value of node $d/xml/el1 with "1-UPDATE-2",insert node <el4>4</el4> into $d/xml)
) return $d'
passing xmldoc
returning content) where id = 1;I get the following trace:
*** 2012-03-13 10:31:42.280
--------- XQuery NO rewrt expr BEG-----
non-simple content in target expression
--------- XQuery NO rewrt expr END-----
--------- XQuery NO rewrt expr BEG-----
not delete/insert/replace in modify clause
--------- XQuery NO rewrt expr END-----
Non-iterator usage
Non-iterator usageDoes this also indicate that a rewrite is not occurring, or is this only when a message like "NO REWRITE Reason ==> xseq:not optuop" is traced?
I'll try XSLT in the meantime.

XML validation in sender file adapter
Hi
I am using FCC on the sender file adapter ....i need to make sure that one of the fields should always be integer else the sender adapter should give error
Can i use xml validation with FCC on the sender file adapter?Hi Hema,
As per understanding you need to check one or few fields value is integer or not.
You can achieve in 2 ways :
Case1:Using inbuilt xml validation options.
For 7.11 and below
1)In ESR/Message type/Export the xsd to local machine.
2)Insert the xsd file in the below loc
/usr/sap/<sid>/DVEBMGS00/j2ee/cluster/server0/validation/schema/
<guid>/<namespace1>/<service_interface_name>/<namespace2>
<sid>: System ID of the server instance.
<guid>: The GUID of the SWCV.
<namespace1> : The namespace within which the service interface is defined.
<service_interface_name> : The name of the service interface.
<namespace2>
: The namespace of the Message Type used by the service interface. In many
instances, namespace1 and namespace2 are the same.
Italic path folders need to create by you.
For 7.3 and above
Michal's PI tips: XML validation - changes in 7.3
Case 2 :Handling using simple UDF.
Input-->UDF-->Output
try {
Integer.parseInt(input);
return input ;
catch(NumberFormatException e) {
throw new StreamTransformationException( "Input field value for xyz field "+input+"is not in integer format.Plz correct it");

Your error message are not displaying because u does not made Message-Resoucrce property file (Resource Bundle) when you make it .
give it entry in

Can anyone please point out why am I getting the error?
ThanksHi CarlSun,
Thanks for the reply. I have made the changes suggested by you.
I have few queries:
1. Can we use attribute "source" in the description tag?
I have created a local html page and specified it in source attribute. but the Extension Manager CS6 did not render the local html page and displayed the following:
No description avaliable. Click the following link for more details.
"http://www.abcd.html". Is it possible to display a local html page in Extension Manager CS6?
2. Can I display an image (png) in CDATA under description tag? If yes, then can you please guide me how can I do so?
3. As suggested in tech notes MXI file must include UTF-8 encoding as header (<?xml version="1.0" encoding="UTF-8"?>). The MXI I am using does not have this header. Do I need to include the header?
Thanks -
XML Validation in PI 7.1 - Restart and skip validation possible, but how?
Hello all,
I read about schema validation in PI 7.1 and did a few tests on my own, but could not restart and skip validation for invalid payloaded messages. The documents say it is possible.
Anyone know how? Thanks.
BTW, I really think putting the schemas in server file system will cause a lot of authorization trouble in enterprises. No one gives access to the server filesystem and I don't think they will also like to open the required subdirectories for share. Asking the basis team to create the folder structures and maintaining schemas would be another pain. Don't you also think that SAP could find a better approach, like automatically uploading the schemas to the filesystem, or validating them from repository directly if possible?
Kind regards,
GökhanHi Gökhan,
I am facing the same issue.
I set up outbound xml validation in receiver agreement and tested it with valid and invalid messages.
The validation works fine.
But in case of validation error I tried to restart with skipping the validation. But this wasn't possible.
I am always facing the same valdiation error.
I already tried all different tools I know (sxi_monitor, message monitoring in rwb and in nwa)
I am working on PI 7.11 SP6
Did you find a solution for skipping the validation for a single message out of the monitoring?
I know that there is the possibility of deactivate the validation in receiver agreement but thid doesn't meet the requirement of skip the validation only for a single message.
Maybe anyone else faced and solved this issue already.
Thanks in advance

XML Validation - How to raise an alert
Hi PI Experts,
I enabled XML validation at "Validtion by Adapetr Engine". Its working fine. But how to integrate XML validation error with Alert Monitoring. Please advise.
Here below the error from Audit log:

Ravi KanakamHi Ravi,
Are you getting other adapter engine alerts? Or only you are not getting xml validation ones? Also take a look at this:

XML Validation: ignore non-XML-Header in XML-file(payload): any solutions?
Dear Experts,
after I finally managed to configure the XML Validation, we're facing the next problem:
The payload of the XML files looks like that:
Abcdef#ABCDEF
AbcDef#123
<?xml version="1.0" encoding="UTF-8"?><Document xmlns.....
as you can see, there's a header which is necessary. The XML Validation works fine if the header is removed manually for testing. If the header is not removed, the validation is not possible ("Content is not allowed in prolog.")
Is it possible to realise the validation WITH that header? Can I tell SAP PI to ignore the header? Or make any changes to the XSD file?
Thanks alot!Hi Armin,

> After leaving SAP PI, those 2 lines have to be in that exact place (before the XML part) for further processing. Just deleting it wouldn't be enought. Does the complex design you mentioned complay with this requirement?
You can put it into the message instead of deleting. And rebuild the "header" in the second step. So you can fullfill the requirement. As mentioned before: The design is complex, this will lead later on to problems. Any change will be difficult, as another developer had to read a long documentation.
An alternative would be to do all with one interface mapping (without validation):
1. ABAP / Java mapping deleting the "header" (put it to memory)
2. Messges Mapping 1:1 each field (will fail in case of wrong format and act as validator)
3. ABAP / Java mapping restoring the header
4. Alert will be raised in case of an error (to get the result of the validation)
Armin Kern wrote:
> I also thought about splitting the message, deleting those 2 rows in one of the messages, sending this one message to PI again, validate it and if it is correct, send the second message (without mapping) to the final destination. No idea if that is possible at all..
As well possible. You would need a virtual receiver for the first message, which is sending back a response. For example a servlett, a proxy or a RFC module. In that design you put some logic to the sender, what is actually not bad. But if you do so, why you dont validate there as well (for example with Java)? It would make your design much easier..

Since there is no XML validation currently in the Flex/Flash framework, I've decided to start a class that parses a string in an effort to validate the markup, returning whether the XML is valid. I have a need for it in my non-server based application, and have read in numerous places where there is desire for it as well. I have built the class far enough to get the ball rollin', but figure it should be :
A) available to the community
B) able to be improved upon by the community
If you improve upon the code, please post your work here so everyone can benefit.
Here is the source code :
XML Validator : v0.2 - last edit by Justin Myers | J2 CREATIVE MEDIA DESIGN
NOTES:
Parser is a bit weak and needs work.
Still need to :
- Make sure tags are ended properly
- Make sure there is space between tag name and attribute
Parser currently handles :
- Making sure there is no space between tags (with exception to white space)
- Making sure that attributes open and close properly
- Making sure there is proper space after an attribute or that it is immediately followed with the tag closing

How to get the data validated with those rules given the source data is in a xml file
The "integrity rules"?
Since they have to be ececutable code I'd suggest Java classes...
How to get the data validated with those rules given the source data is in a xml file
as @hsc71 wrote, that each XML element select the rules this particular element should pass and run each rule with the current element as parameter.
This meight be easiser in the Rules have a common interface like
interface Rule{
public boolean isPassedBy(XmlElement theCurrentElement, XmlElement theRootElement);
You could use the ServiceRegistry class from the JVM to fetch the known rules, so that you can add new ones with minimum effort.
