XPath: contains()

Hello!
We are using XPath conditions in the interface determinations to select a specific mapping according to the payload:
e.g. execute mapping I if:
/ORDERS05[(IDOC/EDI_DC40/MESCOD="IC") and (IDOC/E1EDK14[QUALF="014"]/ORGID="P475")]
e.g. execute mapping II if:
/ORDERS05[(IDOC/EDI_DC40/MESCOD="IC") and (IDOC/E1EDK14[QUALF="014"]/ORGID!="P475")] and not(contains(/ORDERS05/IDOC/E1EDP01/E1EDP19[QUALF="002"]/IDTNR,"#"))
It works fine for mapping I but if mapping II should be triggered the message fails with: "Unable to find inbound interface".
However, if I test the XPath for the second test IDoc in my XPath test tool it returns TRUE so the XPath should be correct. Could it be that the not() and contains() XPath functions are not supported in XI?

Hello Stefan!
> /people/shabarish.vijayakumar/blog/2006/06/07/customise-your-xpath-expressions-in-receiver-determination
Thanks, the blog was very helpful:
"Note : It is not possible to have any operator like 'and', 'or' etc outside the brackets [ ]."
solved my problem. I just changed the XPath to
/ORDERS05[IDOC/EDI_DC40/MESCOD="IC" and IDOC/E1EDK14[QUALF="014"]/ORGID!="P475" and IDOC/E1EDK14[QUALF="014"]/ORGID!="P476" and IDOC/E1EDK14[QUALF="014"]/ORGID!="P477" and IDOC/E1EDK14[QUALF="014"]/ORGID!="P478" and not(contains(/IDOC/E1EDP01/E1EDP19[QUALF="002"]/IDTNR,"#"))]
and now the correct interface mapping is executed!
> XPATH expresens must return an element or node, not a boolean value.
I'm using the XPath in the interface determination, not in the receiver determination. The XPath needs to return TRUE for the interface mapping that needs to be executed. It works as long as you make sure only ONE of the XPaths returns TRUE.
PS: We will meet again at SAP shortly, I have accepted an offer as XI architect in SAP's internal IT starting from April.

XPath contains or compare with collation

I intend to use the XPath contains which matches on whole words.
Ex: contains ("abcd xyz","abc") should return false
contains ("abc xyz","abc") should return true
I understand that this can be done using collation.
I have been trying to understand this by reading related documentation on w3.org but am not able to understand it.
Can someone please help me with an example?
Thanks,

Try to use one of the following Data Structure classes which implements Set interface. Set interface does not contain duplicate elements which means that if e1.equals(e2) and then it does not take e2 into its storage.
So try to use these classes;
AbstractSet, CopyOnWriteArraySet, EnumSet, HashSet, JobStateReasons, LinkedHashSet, TreeSet

Namespace problem The result is empty for the XPath expression

I have a problem with BPEL namespaces. The webservice that my BPEL process is using has changed namespaces (i.e. the java code package names changed and therefore the namespaces associated with the packages.)
Before there was only one namespace associated with this web services; now there are multiple namespaces.
I have changed the namespaces in my .bpel file; however I get the result is empty for XPath expression:
/nsxml0:getMailResponse/nsxml0:getMailReturn/nsxml1:mailOut
Any help appreciated...:(

hey b-o-s-t-o-n,
have your verified that the namespace import is correct, and with the right prefix
you xpath contains 2 namespace prefixes
/nsxml0:getMailResponse/nsxml0:getMailReturn/nsxml1:mailOut
so check the bpel file and maybe the wsdl that has been generated (that inclused the plnk extensions for your external service)
this is the most common issue ..

I see two issues off a quick eye-ball of the code 
#1) You insert an empty clob into your table, load a local variable with the XML from disk, and then query the table. You never insert the XML into the table so you are querying on an empty column in the table. 
#2) extractValue allows a third parm which is the namespace string. Since your XPath contains ns1: you'll need to use the third parm

You can use the xpath contains() function or use ora:contains() extension.

Read xml nodes

Hello to everyone.
I 'm trying to build an rss reader in PLSQL.
I'm confused and i want your help.
I used dbms_xmlparser to parse an xml and read its nodes but I have a problem with the character set (xml is iso-8859-7 but i cannot read it).
So, i thought that if i made a request to the xml url using UTL_HTTP and GET method, then i could use clob response and from that to extract the nodes using EXTRACTVALUE function etc and all these in UTF-8
Here is a sample of the xml:

I'd like to loop through these nodes and take only the first 3 of them (eg first 3 "title"), not all the nodes.
Is there any suggestion either for the encoding or for the loop through the nodes...?
Thank you
Edited by: Alexandra T. on 28 Σεπ 2009 7:09 πμ

Just some quick thoughts.
You could use [.getXML|http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28419/t_dburi.htm#i1011991] of HTTPURITYPE to retrieve the remote XML as XML (or getClob if you want/need to bring it back as a CLOB).
For pulling the first three, two options are to have the data as an XML Type and setup a for 1..3 loop and do an extract where the XPath contains the loop counter in it, such as item[1]/title, item[2]/title, item[3]/title. Of you could not worry about the loop and just hard-code those three extracts into your code.
I've never had to deal with different character sets when dealing with XML so I can't offer much advice other than to search oracle sites for that info. (hint: via Google use site:forums.oracle.com and site:oracle.com).
Update: And then I run across this while reading some other forums {thread:id=613170}. Pay attention to the use of NLS_CHARSET_ID.

What do you mean by regular xml document? Are you referring to fact that its missing a root element? if yes it can be added as below
USE AdventureWorks;

XPATH - Scope of BPM container objects

Hi,
I have a question.
When we declare container objects in BPM, the scope is mentioned as "Process".
Does this mean that I can use any container objects declared within the process anywhere.
What I am trying to do is, after a SYNC step, I have a ASYNC step. I have to use the response from the SYNC step in the ASYNC step.
The problem is that the interface of SYNC's response differs from ASYNC's request.
So I was wondering if I could mention the XPATH of SYNC's response while doing the receiver determination for ASYNC.
I tried and it does not work. But technically I assume it has to work.
Could someone point out where I am going wrong ( My understanding / Steps that I am following ).
Thank you team.

When you do the mapping outside of BPM (which is recommended anyway)
then you send the sync response directly as async request and do receiver det. and mapping. to the new structure.
when you do mapping and receiver det. inside BPM, you should be able to access all container elements, but I do not have experience with this.

Poor performance when xmlquery contains attribute matching XPATH

We send a select xmlquery to Oracle 11g database, if the query contains an XPATH that has an attribute name test in it, the performance is significantly worse than if indexing is used. Here are the two queries:
1)
select xmlquery('declare default element namespace "namespace"; for $e at $pos in $c/services/service let $result := if ($pos >= 2) then "|||||ERROR|||||" else $e return $result' passing document as "c" RETURNING CONTENT).getStringVal(), "LASTUPDATE" from services where id = :1
2)
select xmlquery('declare default element namespace "namespace"; for $e at $pos in $c/services/service[1] let $result := if ($pos >= 2) then "|||||ERROR|||||" else $e return $result' passing document as "c" RETURNING CONTENT).getStringVal(), "LASTUPDATE" from services where id = :1
The only difference is the two XPATHS:
1)$c/services/service
2)$c/services/service[1]
The second query performs 7X to 10X better than the first. More specifically, the Oracle DB CPU will reach 80-100% with only 40 tps of the first query but the second could hit 500 tps.
We would expect the first to perform slightly worse than the second, because Oracle would need to compare the uri values in the doc to the query. But, the documents being searched only contain one service/@uri.
Does anyone know why the performance is so bad with the first query? Is there anything we can do to tune the DB to help in this area. We need to be able to do the first query but the current CPU utilization is extremely too much.

sorry, number 1 should be $services/service(@uri="test"). That should be [ instead of (, the forum wasn't displaying it correctly above. It should be that way in the query as well.

I agree with Shankycheil here, querying XPath will return XMLNode and thus can't be assigned to XMLNode.
But for debatching in Orchestration using Xpath is not a very good idea.
Because using XPATH loads the complete message in memory(XML Structure) and then performs processing.
This approach is always prone to throwing Out of Memory exception and low in performance also.
Therefore I would suggest you to perform debatching by calling XML Disassembler(XMLReceive) pipeline.
As pipeline works with Stream it will have better performance and you will also get complete control over the messages.
Refer the below samples for debatching using XML Receive pipeline within Orchestration.

Xpath expression substring or contains

Hi ,
I have this inbound source message
<?xml version="1.0" encoding="UTF-8" ?>
- <rfc:Z_RFC xmlns:rfc="urn:sap-com:document:sap:rfc:functions">
- <TO_DATA>
- <item>
<LINE>000012E3 ABCD 3I 20070911164941</LINE>
</item>
</TO_DATA>
</rfc:Z_RFC>
and two inbound interfaces
condition is , if "ABCD" exists in the LINE field(type string) then the corresponding Interface mapping should execute.
I know the exact location of "ABCD occurence so I can use either contains or substring functions.
I tried /P1:Z_RFC/TO_DATA/item[substring(LINE,X,Y)="ABCD"] EX no right operand
/P1:Z_RFC/TO_DATA/item[substring(LINE,X,Y)]= "ABCD" with right operand
substring((/P1:Z_RFC/TO_DATA/item/LINE),X,Y) = "ABCD"
similarly I tried around with "contains" function too.
but not able to apply exactly, I tried with different options looking at different blogs in SDN.
so how should be the Xpath expression ?
thank you.
Babu

yes,
I have two different interface mappings in interface determination.
I have same sender RFC interface(outbound) and two different target interfaces and so why I have two different interface mapping,MMs.
sender and reciever systems are same in both cases.
.................condition1--interface mapping1--
sender -
|-- |--
Receiver
.................condition2--interface mapping2--
>>>two dfferent interfaces one when the condition satisfies and other when the condition doens'tmacth...
I know why you are asking this,if we have one interface map and two target interfaces then we need to go for enhanced interface determination.
and need not to be just "substring" or "contains" function ,just any function will do.
so any suggestion about the above scenario in ASCII diagram?
thank you.
Babu

Customised xpath expression for does not contain

XPATH Predicate for container variable of simple type in BPM

Hi Experts,
I have read various threads and blogs with this topic and as I couldn't get a clear view, hence I am raising it here. In my BPM, I am collecting idocs by means of a finite loop. I have used a receive step, container step(to append the idocs) and another container(to increment the counter_variable) in a loop. I want to run the loop for the condition: counter_variable<=3 whereas 'counter_variable' is a container variable of 'simple XSD type(XSD: integer)'.
All the blogs and threads have demonstrated like how to use the EX operator with container variable of type 'Abstract interface'. But how can i incorporate the above scenario for a container variable of simple xsd type ? Please share your ideas.
Regards,
Laawanya

so this is what you need to do,
1. in your loop have a container operation that will increment your simple integer variable each time a message come in.
2. for your loop the condition will be, left operand (simple integer variable) /= (not equal) 3 (Constant)
Ref: SAP BASIS (SWCV) -> http://sap.com/xi/XI/System/Patterns -> Integration Process -> BpmPatternCollectPayload
the only difference here will be the loop condition to be altered as i have mentioned above.

Problem using views containing xpath expressions with Oracle Forms

Mark,
Nice to see you back on the forum answering questions.
This example is based on the standard purchaseorder schema.
i registered the schema, created a relational table and then created
a view using xpath.everything works well and i am able to select the data
using sql*plus. Now this views is like any other view, when i describe the
view, i can see the all the data types are valid for the columns and also the lengths.
Now when i try to base a data block in oracle forms using this view, i get error
"ORA-24324 - service handle not initialized."
Whereas if i create another view on top of the first view and then base the data block on this view, it works for me. i described the second view from sql*plus and everything seems to be same for me.
this is the same behaviour from database 9i r2 and it exists in 10g r1 also.
Any hints as what might be the problem or you would like me to file a tar for this.
create or replace view purchaseorder_header_xml
as
select id
       ,extractvalue(xml_data, '/PurchaseOrder/Reference') reference
       ,extractvalue(xml_data, '/PurchaseOrder/Requestor') requestor
       ,extractvalue(xml_data, '/PurchaseOrder/User')      po_user
       ,extractvalue(xml_data, '/PurchaseOrder/CostCenter') costcenter
       ,extractvalue(xml_data, '/PurchaseOrder/SpecialInstructions') spl_instructions
from tab_xmldata
create or replace view purchaseorder_header
as select * from purchaseorder_header_xml

Not used Forms for years. However I suspect that Forms is trying to poke around behind the view and not understanding what it sees. I expect you'll need to open a Forms Tar to get to the bottom of this. It also appears that you a workaround which is to create a view on the view by the sound of it..
