XPath predicate on wildcard

I am trying to get a (for me!) complex XPath expression working, and having trouble. If I use this it finds all nodes in the Arch Package Set, including Removals.
$SetExpression = "/Definitions/PackageSets/PackageSet[@id='Arch']/*"
But if I do this it returns nothing, rather than returning the two Rollout nodes that are there.
$SetExpression = "/Definitions/PackageSets/PackageSet[@id='Arch']/*[Name!='Removal']"
So, is it not possible to apply a predicate to a wildcard?

And the answer is...
$SetExpression = "/Definitions/PackageSets/PackageSet[@id='Arch']/*[local-name()!='Removal']"
Good grief! ;)

Translate() function in an xpath predicate

I'm trying to use the translate() function in an xpath predicate, and it appears to be having no effect. For instance, I have the following XML document (abbreviated for clarity):
<metadata>
<baseObject>
<PublicationTime>2003-06-30T21:45:56Z</PublicationTime>
</baseObject>
</metadata>
The following xpath expression returns no nodes:
metadata[translate(baseObject/PublicationTime, "-:TZ", "") = "20030630214556"]
But this next expression does return a node:
metadata[translate(baseObject/PublicationTime, "-:TZ", "") = "2003-06-30T21:45:56Z"]
It appears to me that the translate function is not removing the -, :, T, and Z characters as would be expected. Am I misunderstanding the usage of the translate function, making an error in my xpath expression, or is there some other explanation?
Thanks.

This looks like a bug in the implementation of translate

Xpath predicates

Hi.
I get wrong results when running the following query that includes predicates:
<bpelx:append>
<bpelx:from expression="ora:getNodes('Campi','/client:CambioResidenza/client:Individui/client:Individuo[IntestatarioVeicoli=true() or IntestatarioPatente=true()]')"/>
<bpelx:to variable="IndividuiProprietariPatentati"
query="/client:Individui"/>
</bpelx:append>
getNodes returns an empy set.
Whats wrong with the predicate syntax?
Thanks for yout help,
Mick
Edited by: Mick on 28-dic-2010 15.03

never faced this issue rather I never used condition in []. Seems like a logical corruption in the evaluation of the condition. Have you tried removing one condition and by keeping only one condition at a time ? Which version of BPEL/platform you are using ??? can you provide the source structure xsd for which you are using getNodes().

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.

XPath Expression Problem

Hi again,
still a newb and stillsomequestions, but hope dies at last :)
I want to extract values from a xml file which is stored in a table.
i have the following code:
COLUMN div DEFAULT
SELECT extract(value(x), '//DIV/@ ID = ''FXAC93006ENC.0001.01.00''/text()').getStringVal() AS div
FROM versuch2 x;
With this code ive got the following Error Message: ORA:31012: Not supported XPath Statement.
I tried this XPath statement in SlyXML and got a boolean:true result, so i think its not a xpath problem.
Isthere a syntax problem?
Thx for help!

The correct syntax for fetching attributes is different from what you did.
Not sure which syntax is the standard, but the Oracle Version seems more intuitive (too me). Why? Because an attribute is on the same hierachy level of the xml tag and therefore should not be queried with an additional /.
SQL> with versuch2 as (select xmltype('<doc><div id="FXAC93006ENC.0001.01.00">Test</div></doc>') xmlcol from dual)
2 SELECT extract(xmlcol, '//div[@id="FXAC93006ENC.0001.01.00"]/ text()').getStringVal() AS div
3 FROM versuch2 x;

CcBPM - switch with a condition (greater than) in XI 7.0

Hello.
I have this BPM that must have a switch condition like:
IF <field xpto> of the received message is greater than 0.
branch 1.
ELSE.
branch 2.
ENDIF.
In XI 7.1 is easy, because the condition editor has logical expressions like >, <, etc ...
In XI 7.0 we don't have that, but in SAP help I read:
You want to formulate the following condition: The booking number (BookingNumber) is greater than 0100.
Since the greater than (>) operator is not available in the condition editor, you can use the following solution: You define the relevant logical expression in the expression editor by means of an XPath predicate, and assign it to a node element. Using the condition editor you then just query the existence of this node element (by using the existence operator (EX)).
This means you first create the following expression in the expression editor:
/FlightBookingOrderConfirmation [BookingID/BookingNumber > 0100]
Using the condition editor, you then formulate the following condition:
(/FlightBookingOrderConfirmation [BookingID/BookingNumber > 0100] EX)
The meaning of this condition is as follows:
A node element FlightBookingOrderConfirmation exists, to which the following applies: The content of the subelement BookingID/BookingNumber is greater than 0100.
In my example, the xpath for the variable is:
/p4:EventMessage/p4:MessageBody/p5:Order/p5:Totals/p5:TotalGrossAmount
But i'm not getting how to use the bracket condition.
Regards,
Valter Oliveira.
Edited by: Valter Oliveira on Mar 10, 2009 6:04 PM

Hi, valter:
Existence operator (EX) is to check if the node exist in your source message or not.
It is used in Conditional Editor, mostly in the conditional routing in ID.
IF <field xpto> of the received message is greater than 0.
branch 1.
ELSE.
branch 2.
ENDIF.
If your branch 1 or 2 is a send step, then you can use the conditional routing to substitute BPM logic.
otherwise, you can not use conditon editor to replace your BPM logics.

IDOC - FILE Issue

SCENARIO: IDOC-FILE
IDOC: COND_A04
DESIGN: Two namespaces with DT,MT,MI,MM,IM for sales condition and purchase condition.
Here based on the condition(LIFNR) i have to schedule the message to either salesconditon CC or purchasecondition CC.
REQUIREMENT: If LIFNR has value in IDOC it should go to SALESCONDITION receiver CC, else PURCHASECONDITION.
I need the condition to be given in receiver determination.
note: we are using different structures for salescondition and purchase condition even the idoc is same.
thanks in advance

Hi,
First check some links on xpath and then put the condition in receiver determination

How do you get brackets [ ] to be visible in the forumn?

When I'm responding to posts with XPATH predicates they keep disappearing in the post because the forumn formatting engine thinks it's a URL. Does anybody know how to workaround this issue?

ORA-00932 Using Structured XML Table

Hello,
I'm having a problem in trying to create and use a Structured XML Table.
I have created very small sample that illustrates my problem:
I have registered the following schema:
<schema
targetNamespace="http://tsldev01.thesoftlife.com:7887/SoftTop/Schemas/Jjm.xsd"
xmlns:jjm="http://tsldev01.thesoftlife.com:7887/SoftTop/Schemas/Jjm.xsd" xmlns="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<complexType name="JjmType">
<choice maxOccurs="unbounded">
<element name = "Key" type = "string"></element>
<element name = "Type" type = "string"></element>
<element name = "AccessID" type = "string"></element>
</choice>
</complexType>
<element name ="Jjm" type="jjm:JjmType"/>
</schema>'
Then I created the following table:
CREATE TABLE JJM_SCHEMA of XMLType
XMLSCHEMA "http://tsldev01.thesoftlife.com:7887/SoftTop/Schemas/Jjm.xsd"
ELEMENT "Jjm";
Then I inserted the following row:
insert into JJM_SCHEMA values(xmltype('<Jjm
                         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                         xsi:noNamespaceSchemaLocation="http://tsldev01.thesoftlife.com:7887/SoftTop/Schemas/Jjm.xsd">
<Key>anp</Key>
               <Type>User</Type>
<AccessID>TSL2</AccessID>
</Jjm>'));
Then I do the following query:
SELECT
extract(value(x),
'/Jjm[Type="User"]') AS jjmXML FROM JJM_SCHEMA x
WHERE existsNode(value(x),'/Jjm[Type="User"]') = 1;
I get this error:
ERROR at line 1:
ORA-00932: inconsistent datatypes: expected UDT got CHAR
However, if I remove the Xpath predicate [Type="User"] from the "extract()" function and WHERE clause...
SELECT
extract(value(x),
'/Jjm') AS jjmXML FROM JJM_SCHEMA x
WHERE existsNode(value(x),'/Jjm') = 1;
The query works.
Also, If I change the schema from <choice maxOccurs="unbounded"> to <sequence>... either query works.
I need the "choice" type element to work with the Xpath predicate. Am I missing something?
Thanks in advance.

Help!! Calling PL/SQL with table of objects params

Hi JDBC experts,
This is probably a familiar problem to many of you and I was hoping you can help me.
I have a JDBC application that makes calls to a PL/SQL stored procedure that accepts and returns tables (arrays) of objects. I have an equivalent representation of these in Java (the object is a simple Java class and the array of objects is a subclass of ArrayList). The object has around 10 attributes (varchar and number) and the call typically accepts and returns between 50 and 100 objects.
I noticed that converting from one representation to the other before and after the JDBC call is very time consuming. Before calling the procedure, I need to instantiate a new oracle.sql.ARRAY and fill it with oracle.sql.STRUCT equivalents for each object in my ArrayList. After the procedure call returns, I need to instantiate a new ArrayList and fill it with my Java object representation for each oracle.sql.STRUCT in the returned oracle.sql.ARRAY. Given the # of objects returned and the size of each object, this causes performance degradation.
Is there any way I can avoid the above conversion overhead? I was reading somewhere about jpub and CustomDatum. I tried it out but the code that sqlj generated looked rather complex - but if this is the recommended approach, I can follow that.
Also, are there any java code examples for dealing with table of (non-scalar) objects with CustomDatum? I saw some code for using CustomDatum with single objects but not with a table of objects.
Your help is much appreciated!
Thanks,
Niranjan

I would do it like this :
- use existsNode function in the filter predicate to look for candidate rows regardless of the number of occurrences of target nodes in the document
- use XPath predicates on attributes to restrict target nodes

    </sectie>
    <sectie cods="6">
      <prodv codp="2"/>
    </sectie>
</listsectii>
</soc>
Of course, that implies there's already an existing "cant" attribute (not the case in your samples).
If you actually need to create one, then you must use insertChildXML() instead.

Dumping xml content with tags

Hi,
To help me debugging an rtf template, i would like do display in my pdf output the current node and sub nodeq whis its tags (not only the values). How can i do this ?
In infopath, i use xml property of node with vbscript.
thank's

Thank you for your reply,
Local-name() is not ok for me, because i want to display in my rtf (for debugging xpath predicates) a node and his subnodes : ie :
<nodeA>
<nodeB>value 1</nodeB>
<nodeB>vlaue 2</nodeB>
</nodeA>
local-name(nodeA) does only display nodeA
thank's

Finder Methods - Does xmlbeans support this?

Finder Methods - Does xmlbeans support this?
Hi,
Q1 - Is there currently a mechanism via generated xmlbeans java classes to
find specific data required (from within the java generated methods
provided). For example assuming in the following xml (see below) if one has
already loaded the <main-item> via xmlbean generated java classes, but then
wishes to find the appropriate configs/config within this section of the xml
(i.e. the main-item entry "config" is a reference to one of the "config"
items under "configs") , does XMLBeans currently support this? That is, it
would be nice to have finder methods on the generated java classes so once
you have a <configs> java instance you can issue a finder method for a
<config> item and pass the <config-name> in. For example:
What is available: MainXML.getConfigs().getConfig(23) -> i.e. put in
index,
However what about: MainXML.getConfigs().findConfig ("mainConfig");
Q2 - If there is no support for this within the generated java classes what
is recommended? Via xpath? Have to write your own short java finder classes
which iterate through until the item is found?

Hello Greg,
To my knowledge, the reference-specific kind of function you're asking for
isn't supported. But if you're writing code on WebLogic Platform 8.1, you
can use XPath/XQuery to accomplish this. Incidentally, your XML belowopens
with MainXML and closes with sns_config, but I'll assume it's MainXML.
To retrieve a main-config/main-item/config element when you know the
config-name element's value, you could use the following expression (where
the mainXml variable is a MainXMLDocument instance):
String queryExpression = "$this/MainXML/configs/config[config-name=
'mainConfig']";
ConfigType[] configs =
(ConfigType[])mainXml.selectPath(queryExpression);
The configs array would contain one item in this case. The second linewould
throw a class cast exception if no results were returned.
Note that XPath predicates aren't supported in XMLBeans outside thecontext
of WebLogic, but simple path expressions are.

What is this type of searching called? Need assistance please.

I have a requirement to create a view from an xmltype column. One of the columns would be:
/Invoice/ReferenceNumbers/ReferenceNumberType=PURCHASE_ORDER_NUMBER/ReferenceNumber...and the respective fragment would look like:

       <ReferenceNumber>?</ReferenceNumber>
       <Description>?</Description>
       <ReferenceNumberType>?</ReferenceNumberType>

            PO_NUMBER path '/Invoice/ReferenceNumbers/ReferenceNumberType=PURCHASE_ORDER_NUMBER/ReferenceNumber/text()'
         ) m
/* I know this is incorrect, but trying to detail what I'm getting after */Any help would be appreciated...I'll research how to do that in sql xquery, I just don't know what it's called.
Thank you in advance.

You're close. You just need a correct XPath expression.
SELECT x.*
FROM invoice t
   , XMLTable(
       '$i/Invoice'
       passing i.doc as "i"
       columns
         invoice_number number path 'InvoiceHeader/invoiceNumber'
       , po_number      number path 'ReferenceNumbers/ReferenceNumber[ReferenceNumberType="PURCHASE_ORDER_NUMBER"]/ReferenceNumber'
     ) x
/ The part between square brackets is an XPath predicate, it restricts the selected ReferenceNumber elements to those having a child ReferenceNumberType = "PURCHASE_ORDER_NUMBER", then the rest of the expression selects the child named ReferenceNumber (assuming it's not an error).

Hello
My conf :
SQL> select * from V$VERSION;
BANNER
Oracle Database 11g Express Edition Release 11.2.0.2.0 - Beta

CORE 11.2.0.2.0 Production
TNS for 32-bit Windows: Version 11.2.0.2.0 - Beta
NLSRTL Version 11.2.0.2.0 - Production
One of my XML stored document :
SQL> SELECT v.OBJECT_VALUE
2 FROM vol_reel_xml_2 v
3 WHERE XMLEXISTS('$obj/vol_reel[@nvol="AF6154"]'
4 PASSING v.OBJECT_VALUE AS "obj")
5 AND XMLEXISTS('$obj/vol_reel/passagers/pax[@num_carte=13457934]'
6 PASSING v.OBJECT_VALUE AS "obj")
7 AND TO_DATE(XMLCAST(
8 XMLQUERY('$obj/vol_reel/@datev'
9 PASSING BY VALUE v.OBJECT_VALUE AS "obj"
10 RETURNING CONTENT)
11 AS VARCHAR2(12)),'YYYY-MM-DD')
12 = TO_DATE('2012-08-31','YYYY-MM-DD');
OBJECT_VALUE
<?xml version="1.0" encoding="WINDOWS-1252"?>
<vol_reel nvol="AF6154" datev="2012-08-31">

<pax num_carte="13457934">

<nom>Blanchet</nom>
<prenom>Agnes</prenom>
<siege>17D</siege>
<prix>146</prix>
</pax>
</passagers>
</vol_reel>
I want update the "prix" element for the first pax (198 replace 190) :
With the same predicates, the element isn't updated :
SQL> UPDATE vol_reel_xml_2 v
2 SET v.OBJECT_VALUE =
3 UPDATEXML(v.OBJECT_VALUE,'/vol_reel/passagers/pax/prix/text()','198')
4 WHERE XMLEXISTS('$obj/vol_reel[@nvol="AF6154"]' PASSING v.OBJECT_VALUE AS "obj")
5 AND XMLEXISTS('$obj/vol_reel/passagers/pax[@num_carte=13457934]'
6 PASSING v.OBJECT_VALUE AS "obj")
7 AND TO_DATE(XMLCAST(
8 XMLQUERY('$obj/vol_reel/@datev'
9 PASSING BY VALUE v.OBJECT_VALUE AS "obj"
10 RETURNING CONTENT)
11 AS VARCHAR2(12)),'YYYY-MM-DD')
12 = TO_DATE('2012-08-31','YYYY-MM-DD');
0 rows updated.
Any idea?
Thanks in advance

Thanks
You're right, my table is created based on XML Schema :

Your succesful update becomes with my configuration :
SQL> UPDATE vol_reel_xml_2 v
2 SET v.object_value =
3 updateXML( v.object_value,
4 '/vol_reel/passagers/pax[@num_carte=13457934]/prix/text()'
5 , 198 )
6 WHERE XMLExists('/vol_reel[@nvol="AF6154" and @datev="2012-08-31"]'
7 passing v.object_value);
SET v.object_value =
ERROR at line 2:
ORA-19162: XPTY0004 - XQuery type mismatch: invalid argument types 'xs:date',
'xs:string' for function '='
By translating the xsd:datetime / Oracle date :
SQL> UPDATE vol_reel_xml_2 v
2 SET v.object_value =
3 updateXML( v.object_value,
4 '/vol_reel/passagers/pax[@num_carte=13457934]/prix/text()',198)
5 WHERE XMLExists('/vol_reel[@nvol="AF6154"]'passing v.object_value)
6 AND TO_DATE(XMLCAST(
7 XMLQUERY('$obj/vol_reel/@datev'
8 PASSING BY VALUE OBJECT_VALUE AS "obj"
9 RETURNING CONTENT)
10 AS VARCHAR2(12)),'YYYY-MM-DD')
11 = TO_DATE('2012-08-31','YYYY-MM-DD');
1 row updated.
I think my fault came from the fact I performed the test num_carte=13457934 in the UPDATE WHERE clause instead of the XPath predicate as previously.
Thanks again

XPath predicate on wildcard
