Xpath expression failed

Hi
Note : I am using SOA suite Developer version
I am using a BPEL Process to read the XML files then I am manipulating the XML.
I am facing a strange issue with BPEL now.
SOme of the XMLs are not processed and I am getting the following error. The same Xmls are processed when I give them as the input next time.
It says that Xpath expression failed, but how the next time it is processing the same XMLs with the same expression.
<2008-09-17 10:53:31,297> <ERROR> <default.collaxa.cube.engine.dispatch> <BaseScheduledWorker::process> Failed to handle dispatch message ... exception ORABPEL-05002
Message handle error.
An exception occurred while attempting to process the message "com.collaxa.cube.engine.dispatch.message.invoke.InvokeInstanceMessage"; the exception is: XPath expression failed to execute.
Error while processing xpath expression, the expression is
Thanks

thanks for the reply mihai,
there is nothing to do with expresssion.
as the same expression is giving the result when i give the same input for the BPEL process.
I hope it is something to do with oracle lite database( i.e memory issue) as I had alredy processed more than 500 XMls using the same Process.
thanks

XPath expression failed to execute.

Hi Everybody ,
I am working AIA PIP 3.1 for JDE E1.I am facing some errors so that i can't proceed.
See the log errors as below:

Hi,
Ya i checked the data for same table,but i didn't get any XREF related information in xref_data table.
Did you mean that, data should already present under AIAFPINST_XREF.Probably xref is meant for storing dynamic value.
Please check the above error and reply me soon.

XPath Expression won't evaluate

Hi,
I am using the ora:doc() function to read an xml and XPath to get extract particular values from it. The issue is that the XPath expression doesnt evaluate correctly on Oracle BPEL process manager where as the same expression is being evaluated correctly in XMLSPY with XPath 1.0.
The XML that I am trying to read is of the format
<?xml version="1.0" encoding="UTF-8"?>

The function being used in OracleBPEL Process manager is

Can somebody please tell me where I could be going wrong?....It'll be a great help.

I have the same problem posted in the constants discussion
Hi
I am trying out the xml file solution. I have places an XML-file in the xmllib location. The file has the following content :
<?xml version="1.0" encoding="UTF-8">
<bpel-domain>
<preferences>
<property name="defaultRentepercentage"> 0.3 </property>
</preferences>
</bpel-domain>
In the Assign step in BPEL I do the following
orcl:lookup-xml('http://localhost:9700/orabpel/xmllib/trials-properties.xml', '/bpel-domain/preferences/property[@name="defaultRentepercentage"]')
The error I get when running this is the following
XPath expression failed to execute.
Error while processing xpath expression, the expression is "orcl:lookup-xml("http://localhost:9700/orabpel/xmllib/trials-properties.xml", "/bpel-domain/preferences/property[@name="defaultRentepercentage"]")", the reason is ExtFuncFunction.
Please verify the xpath query.
I have tried the xpath expression in XMLSpy, and there it seems to work
Am i missing something ?

Failed to initialize the XPath Expression Builder

Any idea what causes this and/or how to fix it?
When I am in the XPath Expression Builder, I pick "Conversion Functions" and start with "string". Inside the "string()" parentheses, I do "bpws:getVariableData()", and select my output variable from an invoke.
Then it SHOULD allow me to continue picking parts of that variable, down to the node I want, but instead I see in my JDeveloper log that a "Failed to initialize the XPath Expression Builder" error has been thrown.
Thoughts appreciated...

Can any of you Oracle guys help with this today?

Concat Operation failing.[Error ORABPEL-10039]: invalid xpath expression

I also tried converting both the variables of concat to string and then giving to concat operation. please let me know what could be the possible way to do this

Hi,
try storing the values of the below into a separate variables var1,var2 and then use concat(bpws:getVariableData('var1'),bpws:getVariableData(var2))....also try using the predicate[] without
bpws:getVariableData for the below variables...for this in the assign activity create copy operation window....u see the xpath text box and u can mention the predicate values there...some
thing like */ns7:parameters/ns7:item[ns7:name='ContractNumber']/ns7:value* , *ns1:AccumilatePLAContracts/ns1:AccumilatePLAType[$PLACount]/ns1:ContractInfoType
[$ContractInfoTypeCount]/ns1:ContractNumber* instead of the below values
bpws:getVariableData('paramsVar','/ns7:parameters/ns7:item[ns7:name='ContractNumber']/ns7:value')

How to evaluate dynamic XPath expression in BPEL?

I have an xml file where I keep many settings for my BPEL process. At runtime, I read the file and I want to select values from it based on values in the process payload.
For example, imagine that the process payload is an order:
<order>
<header>
<id/>
<customer_id/>
<team_id/>
</header>
<items>
<item>
<id/>
<sku/>
<price/>
<quantity/>
</item>
</items>
</order>
Now, in my xml settings file, I have a section where I keep a mapping of "team_id" and "assignment_group", so that for each team id, I can select the appropriate group to whom a task should be assigned. The relevant section of the settings file will look something like this:
<assignment_groups>
<group team_id='0923230'>invoice_approvers</group>
<group team_id='3094303'>order_approvers</group>
<group team_id='3434355'>shipping_approvers</group>
</assignment_groups>
So, imagine I get an order input to my process where the team_id is '3094303'. Now I have to lookup the correct assignment group in my settings file.
So, I construct the dynamic XPath expression
/settings/assignment_groups/group[@team_id=3094303]
I know that this would evaluate to "order_approvers". However, even though I have the XPath expression in a BPEL variable, and I have my settings file as a BPEL variable also, I don't know how to execute the XPath expression against the settings BPEL variable to retrieve the correct value.
Any ideas appreciated.
Thanks,
Jack

James:
Thank you for the response. Incidentally, this is the very same document and section that I have been looking at for guidance. Specifically, the section titled "Dynamically indexing by Constructing an XPath at Run Time" on page 12-13.
I tried to do something similar to the example at the top of page 13:
<variable name="iterator" type="xsd:integer"/>
<assign>
<copy>
<from expression="concat('/invoice/line-item[',bpws:getVariableData('iterator'), ']/line-total')"/>
<to variable="xpath"/>
</copy>
<copy>
<from expression="bpws:getVariableData('input', 'payload',bpws:getVariableData('xpath')) + ..."/>
</copy>
</assign>
I am able to achieve the first copy operation to get my dynamic XPath into a BPEL variable and that's fairly straightforward. But I am unable to get the second copy to work. Specifically, I am not sure what to put in the second argument of the bpws:getVariableData function. I have tried many different combinations, but when I try to compile my program, I get the following compilation error:
Error:
[Error ORABPEL-10902]: compilation failed
[Description]: in "C:\code\TrainingWS\SampleGetSettings\bpel\SampleGetSettings.bpel", XML parsing failed because "org.collaxa.thirdparty.jaxen.expr.DefaultFunctionCallExpr".
[Potential fix]: n/a.
Thanks,

Namespace-aware XPath expressions?

In xMII 11.5.2 b64, I need to extract a node from a SOAP message:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Header/>
   <soapenv:Body>
      <ns0:importRequest xmlns:ns0="http://www.acme.com/1.0/schemas">
        <FOO>
The following xMII Assign action Link returns me the entire <FOO> nodeset:
Transaction.SOAPRequest{/soapenv:Envelope/soapenv:Body/ns0:importRequest/*}
However, I cannot be guaranteed that the namespace prefixes will always be "soapenv" and "ns0". For example, the following is perfectly valid:
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP:Header/>
   <SOAP:Body>
      <ZZZ:importRequest xmlns:ZZZ="http://www.acme.com/1.0/schemas">
        <FOO>
When they are changed the XPath fails. I have tried the following:
Transaction.SOAPRequest{/Envelope/Body/importRequest/*}
Transaction.SOAPRequest{//importRequest/*}
but they clearly don't work because the XPath evaluator in xMII is namespace aware (as it should be).
How can I declare namespaces in my XPath expression? Or are there any other alternate ideas?
Thanks,
-tim

I installed SR3 and re-ran my tests and it still fails. Here is my XML snippet:
<?xml version="1.0" encoding="UTF-8"?>
<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:sch="http://www.acme.com/4.3/schemas">
   <SOAP:Header/>
   <SOAP:Body>
      <sch:importIDOCRequest>
         <MATMAS03>
Here's the output from various expressions in the Link editor:
example 1 - getting the name of the root node:
"root node name=" & Transaction.SOAPRequest{name(/*)}
output 1 is predictable:
[INFO ]: root node name=SOAP:Envelope
example 2 - using 'senv' instead of 'SOAP' for the soap-envelope namespace prefix:
"importRequest child node name=" & Transaction.SOAPRequest{name(/senv:Envelope/senv:Body/sch:importIDOCRequest/*)}
output 2:
[INFO ]: importRequest child node name=
example 3 - no namespace prefixes specified:
"importRequest child node name=" & Transaction.SOAPRequest{name(/Envelope/Body/importIDOCRequest/*)}
output 3:
[INFO ]: importRequest child node name=
example 4 - using the same node namespaces prefixes as the input XML:
"importRequest child node name=" & Transaction.SOAPRequest{name(/SOAP:Envelope/SOAP:Body/sch:importIDOCRequest/*)}
output 4:
[INFO ]: importRequest child node name=MATMAS03
Any other ideas?

The XPath expression problem

Hi everyone,
I developed a workflow. I builded and deployed successfully.
And I assing this workflow to a policy.
I create a request, but this request gave a fail.
Error in <assign> expression: <to> value is empty at line "181". The XPath expression : "" returns zero node, when applied to document shown below:
Line 181 :
<copy>
<from variable="inputVariable" part="payload"
query="/ns3:process/ns4:RequestID"/>
<to variable="initiateTaskInput" part="payload"
query="/ns2:initiateTask/task:task/task:payload/task:RequestID"/>
</copy>
It seems that I could not take requestID.
Do you have any idea ?
Thanks for your help.
Regards

How did you resolve the issue? We're facing the same problem.

Getting Invalid XPath expression

Hi,
I am parsing a XML document and reading a node with <xtags:valueOf .. select="product_name"/>. The value of product_name is :
<product_name>SJE6 2004Q1, 1 RTU ESD, All platforms, 1 Year</product_name> , but I am getting the following exception :
org.dom4j.InvalidXPathException: Invalid XPath expression: SJE6 2004Q1, 1 RTU ESD, All platforms, 1 Year Unexpected '2004'
at org.dom4j.xpath.DefaultXPath.parse(DefaultXPath.java:316)

at org.apache.taglibs.xtags.xpath.AbstractTag.createXPath(AbstractTag.java:195)
at org.apache.taglibs.xtags.xpath.VariableTag.setSelect(VariableTag.java:143)
I tried with <xtags:copyOf select=.../node() and text()/> but still getting the same exception. Not sure why its failing on 2004? Help!
Thanks,
-Ashish

The problem was not in the <xtags:valueOf> but in the following expression :
<xtags:variable id="lName" select="<%= product_name %>"/>
where I wasassigning the value of <product_name> to a String (java) variable defined. But this will be another question : why is <xtags:variable> failing?

ORA-31013: Invalid XPATH expression

Hi,
I am getting this error when i am trying to execute a sp which will do xml parsing.
What all i did is i have Oracle database with 9.2.0.1.0 version. The i hav ugraded the database to 9.2.0.6.0 using the Oracle patch. After upgrading the Oracle db to 9.2.0.6.0 i got the below error:
ORA-00600: internal error code,
Then i ran the catpatch.sql to get rid off this error. After running the catpatch.sql the above error gone but i got another error
ORA-31013: Invalid XPATH expression.
What does this mean. The sp is working fine before upgrading the Oracle db to 9.2.0.6.0. Is the patch upgrade corrupted any of the XML libraries or the 9.2.0.6.0 doesn't support the xml parsing or do i need to apply any patch for this.
Please suggest me ASAP since this error has been raised at cusotmer and i am in very much need of this.
The statement which i am using for parsing the xml file is
x.xml_data.extract('/x:recording/@x:ref').getStringVal() from xml_process;
where xml_process is a table of xml_type.
Thanks

Can not construct xml from relative xpath expression: //FormVar

In version 7.0, it was possible to access Form Variables with the (valid) XPath Expression "//FormVariable".
In 7.2.2, using this XPath Expression leads to a stalled action, with message: "can not construct xml from relative xpath expression: //FormVar". (see full stack trace below)
What's wrong? How can I fix this?
Use of relative expression is very very useful during the development phase!

Sorry, i just read my own message in the discussion forum and
discovered all spaces for formating the XML tags where gone.
It should look like this:
[-----xml_type---]
<doc>
__<role>
____actor
____<first>
______john
____</first>
____<last>
______bond
____</last>
__</role>
__<role>
____actor
____<first>
______james
______</first>
____<last>
______smith
____</last>
__</role>
</doc>
semantic:
There are two actors: "john bond" and "james smith"
Querying for "john bond" succeedes which is correct
Querying for "james smith" succeedes which is correct
Querying for "james bond" fails which is correct
Querying for "john smith" succeedes which is an ERROR!
contains(xdata, 'actor INPATH(//role[./first = "john" and ./last
= "smith"])' (= 100 ---> ERROR!)
bye,

Using the variable placeholder ? in an XPath expression

I'm trying to using the variable operator (?) in an Oracle prepared statement used in a query where clause. Here is the query:
select xt.APPLICATION_NAME, xt.VERSION, xt.EVENT_TYPE, xt.SENDING_SITE, xt.RECEIVING_SITE, xt.EVENT_ID
      from AUDITED_EVENT_XML_MIN e,
         XMLTable(XMLNAMESPACES('http://gov/va/med/datasharing/audit/endpoint/audit' AS "xae"),
                '/xae:auditable-event'

Is this a supportable feature or am I doing something wrong?
I didn't see any examples in the Oracle XML DB Developers Guide where there was a ? in an XPath expression.
I also tried "?" with the same issue...

I incorporated this suggestion and it worked very well. Thanks!
Now I have converted my solution to use a structured index. As such, I want to write the where clauses in terms of column names rather than XPath expressions.
I hoped it was as simple as changing the code that generates the XPath expression to generate a SQL expression. After making that change, I'm now getting this error:
Caused by: java.sql.SQLSyntaxErrorException: ORA-00920: invalid relational operator

     at gov.va.med.datasharing.audit.web.dao.jdbc.AuditableEventsQueryDAOImpl.getAuditableEventsByDate(AuditableEventsQueryDAOImpl.java:150)It seemed to me that if it worked for the XPath expression that it should also work for the SQL expression.
The static SQL is:
SELECT PK_ID, EVENT_TYPE, OUTCOME, SENDING_SITE, RECEIVING_SITE, CREATED_TIME, EVENT_ID, PATIENT_ID FROM
(SELECT rownum as rn, PK_ID, EVENT_TYPE, OUTCOME, SENDING_SITE, RECEIVING_SITE, CREATED_TIME, EVENT_ID, PATIENT_ID FROM

        WHERE aet.CREATED_TIME BETWEEN ? AND ?
             AND ?
      ) ORDER BY CREATED_TIME desc
    ) WHERE rn > ? and rn <= ?So I'm thinking that Oracle must perform strong checking in SQL, not allowing the '=' operator to be substituted. If I run this query in Toad, replacing the ? with the SQL, it runs fine...
Can someone tell me whether or not this is a legal substitution?
The SQL that runs in Toad is:
SELECT PK_ID, EVENT_TYPE, OUTCOME, SENDING_SITE, RECEIVING_SITE, CREATED_TIME, EVENT_ID, PATIENT_ID FROM

Using xpath expressions in Document-Builder

Hi all
we have re-designed our (existing) DDX-templates with the Document Builder in LC Workbench. The DDX templates are used to assemble PDFs with LC Assembler-Service.
Now my question: Is it still possible to use XPath-expression in the DDX template? Please find our example below:
The XPath expression works only if we copy&paste the DDX source code directly to the Assembler-Service property view (picture below). But referring the DDX-template doens't interpret the xpath path at run time (2nd picture below). Any help on that will be appreciated!
Works (using DDX source code directly):
Doesn't work (using DDX template):

Hi,
>
I tried to get a portion of an XML by using XPath Expressions as follows:
String xPathExpression =
"declare namespace xq='http://inti.notariado.org/indices' " +
"$this/xq:RULES/xq:RULE[@disabled]";
I think any XPath expressions which use [] are not supported in stand alone
version, but as this is not documented I could be wrong.
