Issue with XSLT Transformation using WSO2 ESB - java

I struggling with XSLT transformer mediator using XSLT mediator in wso2 esb 4.8.1.
The xslt is :
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:fn="http://www.w3.org/2005/02/xpath-functions"
xmlns:ns="http://ep.service.ims.com"
xmlns:ax21="http://ep.service.ims.com/xsd"
exclude-result-prefixes="ns fn">
<xsl:param name="amount"/>
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="//ns:getResponse" />
</xsl:template>
<xsl:template match="ns:getResponse" xmlns:ns="http://ep.service.ims.com">
<ep:credit xmlns:ep="http://ep.service.ims.com" xmlns:xsd="http://ep.service.ims.com/xsd">
<ep:info>
<xsd:amount>
<xsl:value-of select="$amount"/>
</xsd:amount>
<xsd:personInfo>
<xsd:address>
<xsl:value-of select="ns:return/ax21:address"/>
</xsd:address>
<xsd:id>
<xsl:value-of select="ns:return/ax21:id"/>
</xsd:id>
<xsd:name>
<xsl:value-of select="ns:return/ax21:name"/>
</xsd:name>
</xsd:personInfo>
</ep:info>
</ep:credit>
</xsl:template>
</xsl:stylesheet>
and the request XML is :
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Body>
<ns:getResponse xmlns:ns="http://ep.service.ims.com">
<ns:return xsi:type="ax23:PersonInfo" xmlns:ax23="http://ep.service.ims.com/xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<ax23:address>IMS Heath, Omega C, India, bnag</ax23:address>
<ax23:id>100</ax23:id>
<ax23:name>WSO2</ax23:name>
</ns:return>
</ns:getResponse>
</soapenv:Body>
</soapenv:Envelope>
I tried the XSLT transformation in eclipse and some online tool like (http://xslt.online-toolz.com/tools/xslt-transformation.php ) and it is working fine. However when I am trying the same in WSO2 ESB, I am facing following exception.....

What may be the cause of the exception if the XSLT transformation is working fine in other tool ?

The key in the proxy is correct. I might have pasted the wrong XML proxy,
Here is the proxy:

Local entry:
<localEntry xmlns="http://ws.apache.org/ns/synapse" key="xslt1" src="file:resources/creditproxy/personToCredit.xslt"></localEntry>

There was a problem with the local entry. Finally, I was able to fix this issue by adding a local entry like this in the synapse config
<localEntry key="xslt99">
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

exclude-result-prefixes="ns fn">
<xsl:param name="amount"/>
<xsl:output method="xml" omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:apply-templates select="//ns:getResponse"/>
</xsl:template>
<xsl:template match="ns:getResponse">
<ep:credit xmlns:ep="http://ep.service.ims.com" xmlns:xsd="http://ep.service.ims.com/xsd">
<ep:info>

<xsl:value-of select="$amount"/>
</xsd:amount>

<xsl:value-of select="ns:return/ax21:id"/>
</xsd:id>

</xsd:name>
</xsd:personInfo>
</ep:info>
</ep:credit>
</xsl:template>
</xsl:stylesheet>
<description/>
</localEntry>
Initially I was trying to add the local entries like this
<localEntry xmlns="http://ws.apache.org/ns/synapse" key="xslt1" src="file:resources/creditproxy/personToCredit.xslt"></localEntry>
But still I don't know how to specify a xslt file in local entry.?

XSLT 3.0 Identity transform document collection?

I have one XSLT 3.0:
<xsl:stylesheet version="3.0"

The transformation scenario in Oxygen with just one document is without issue:

******************
However, XSLT 3.0 identity transform for collection seems working like this:
<xsl:variable name="inFile" as="node()*" select="collection('hl7.xml')"/>
<xsl:template match="/">
<xsl:text>
ICD9 Target Transformation in the collection is:
</xsl:text>
<xsl:for-each select="$inFile//n1:translation[#codeSystemName = 'ICD-9-CM']/#code">
<xsl:value-of select="$icd10Map($map-keys[translate(normalize-space(current()), '
.;', '') = .])" separator=" , "/>
</xsl:for-each>
</xsl:template>
Result:
ICD9 Target Transformation in the collection is:
H251
H251
K648
K648
K409
K409
S8350
M2332
M2332
S8350
If I change the XSLT to:
<xsl:mode on-no-match="shallow-copy"/>
<xsl:variable name="inFile" as="node()*" select="collection('hl7.xml')"/>
<xsl:template match="n1:translation[#codeSystemName = 'ICD-9-CM']/#code">
<xsl:text>
ICD9 Target Transformation in the collection is:
</xsl:text>
<xsl:for-each select="$inFile">
<xsl:attribute name="code">
<xsl:value-of select="$icd10Map($map-keys[translate(normalize-space(current()), '
.;', '') = .])" separator=" , "/>
</xsl:attribute>
</xsl:for-each>
</xsl:template>
It doesn’t appear any transform happen and is merely an extraction of the URI list in the catalog file hl7.xml.
I develop a Java application which can bulk validate documents against XSD, transform (without collection()) and finally write the documents into database. The logging is the desired result:

Can anyone help to solve the XSLT 3.0 Collections transform issue?
I would use a global parameter
<xsl:param name="inFiles" as="document-node()*" select="collection('hl7.xml')"/>
and then start processing with a named template
<xsl:template name="xsl:initial-template">
<xsl:for-each select="$inFiles">
<xsl:result-document href="/xslt-transform/{tokenize(document-uri(), '/')[last()]}">
<xsl:apply-templates/>
</xsl:result-document>
</xsl:for-each>
</xsl:template>
Then you can xsl:import your first XSLT sample from the question or of course edit it to insert the code I have shown. Make sure you let Saxon start with the named template (-it command line option for Saxon; in oXygen by not providing a source document).

Unable to fetch the specific entire XML tag by using XSLT

I have the below sample XML file
Sample XML:
<?xml version="1.0" encoding="UTF-8"?>
<testng-results skipped="0" failed="0" total="10" passed="10">
<class name="com.transfermoney.Transfer">
<test-method status="PASS" name="setParameter" is-config="true" duration-ms="4"
started-at="2018-08-16T21:43:38Z" finished-at="2018-08-16T21:43:38Z">
<params>
<param index="0">
<value>
<![CDATA[org.testng.TestRunner#31c2affc]]>
</value>
</param>
</params>
<reporter-output>
</reporter-output>
</test-method> <!-- setParameter -->
</class>
<class name="com.transfermoney.Transfer">
<test-method status="FAIL" name="setSettlementFlag" is-config="true" duration-ms="5"
started-at="2018-08-16T21:44:55Z" finished-at="2018-08-16T21:44:55Z">
<reporter-output>
<line>
<![CDATA[runSettlement Value Set :false]]>
</line>
</reporter-output>
</test-method> setSettlementFlag
</class>
</testng-results>
I just want to take the below piece of tags from above XML file based on status PASS (I don't want to take <?XML version, <testng-results> and class tags those are should be ignored).
Expected Output:
<test-method status="PASS" name="setParameter" is-config="true" duration-ms="4"
started-at="2018-08-16T21:43:38Z" finished-at="2018-08-16T21:43:38Z">
<params>
<param index="0">
<value>
<![CDATA[org.testng.TestRunner#31c2affc]]>
</value>
</param>
</params>
<reporter-output>
</reporter-output>
</test-method>
I just used below XSLT to get the above output from sample XML file but It doesn't work It returned all the tags but I just want the above output not other than anything.
XSLT:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes" method="xml"/>"
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:template>
<xsl:template match="class"/>
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
<xsl:for-each select="test-method[#status='PASS']">
<xsl:copy>
<xsl:apply-templates select="#*|node()" />
</xsl:copy>
</xsl:for-each>
</xsl:copy>
</xsl:stylesheet>
Also Using the below java code to run the XSLT and sample XML file
Code:
String XML = fetchDataFrmXML(".//Test//testng-results_2.xml");
Transformer t = TransformerFactory.newInstance().newTransformer(new StreamSource(new StringReader(XSL)));
t.transform(new StreamSource(new StringReader(XML)), new StreamResult(new File(".//Test//Sample1.xml")));
This is the sample payload. But the actual payload had multiple nodes with "PASS" and "Failed" status. I'm just only interested to fetch the PASS node in the above output format.
Any leads....
The result you show could be obtained quite simply by doing just:
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/testng-results">
<xsl:copy-of select="class/test-method[#status='PASS']" />
</xsl:template>
</xsl:stylesheet>
However, in case of more than one test-method having a status of "PASS" this will result in an XML fragment with no single root element. So you'd probably be better off doing:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="/testng-results">
<root>
<xsl:copy-of select="class/test-method[#status='PASS']" />
</root>
</xsl:template>
</xsl:stylesheet>

WSO2 EI - RelayUtils Error while building Passthrough stream

I'm using WSO2 EI 6.3.0 and i want to get data from specific webservice and push this data to an other webservice.
In the first time, i have to get the JWT Token from a first webservice to put it in the second call to get data.
So, i created several sequence to have reusable sequences.
I have the error when i want to inject bearer token header into my endpoint to get data.
STEP OF IN SEQUENCE
During the LogincheckSeq, i call the login_check api to get the JWT Token.
Then during the createBearerTokenSeq, i only create a property with the token recovered from LoginCheckSeq
Then we pass in the CreateBearerTokenSeq, to create a property with the token recovered before from the json response of the LoginCheckEP
Finally, we pass in the last sequence GetCustomerSeq to get customers informations from the webservice in json thanks to the jwt token given in the header (Authorization: Bearer token)
This is my CustomerAPI.xml :

I get well the JWT Token from LoginCechkSeq but i have an error in the getCustomerSeq.
This is the error :

... 24 more
I tried several thing like add this line :
<messageBuilder contentType="application/json" class="org.wso2.carbon.integrator.core.json.JsonStreamBuilder"/>
Or add property with name "messageType" with value "application/json"
But nothing resolve my problem...
If someone has already encountered this problem, I'm taking the solution =)
I found the response.
The Content-Type of the server response is : application/ld+json.
So WSO2 didn't recognize the encoding.
I just added this line into the axis2.xml :
<messageFormatter contentType="application/ld+json" class="org.wso2.carbon.integrator.core.json.JsonStreamFormatter"/>
....
<messageBuilder contentType="application/ld+json"
class="org.wso2.carbon.integrator.core.json.JsonStreamBuilder"/>
And it's work fine ! =)

Unmarshalling without unique node names

I am stuck trying to figure out how to unmarshall an XML file supplied by IBM Cognos.
The structure does not provide unique names for the different child nodes under the element but there is a block of metadata that defines the order of the values.
This is a simplified sample of the XML file.
<?xml version="1.0" encoding="utf-8"?>
<dataset xmlns="http://developer.cognos.com/schemas/xmldata/1/" xmlns:xs="http://www.w3.org/2001/XMLSchema-instance">
<!--
<dataset
xmlns="http://developer.cognos.com/schemas/xmldata/1/"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
xs:schemaLocation="http://developer.cognos.com/schemas/xmldata/1/ xmldata.xsd"
>
-->
<metadata>
<item name="EmployeeID" type="xs:string" length="20"/>
<item name="firstName" type="xs:string" length="50"/>
<item name="lastName" type="xs:string" length="50"/>
</metadata>
<data>
<row>
<value>EMP1</value>
<value>Joe</value>
<value>Blogs</value>
</row>
<row>
<value>EMP2</value>
<value>Mary</value>
<value>Soap</value>
</row>
</data>
</dataset>
I'm using Spring OXM and Castor for this project and I have no control over the XML format as I am pulling it via a web service from a third party system.
Update : I'm not adverse to swapping out Castor for a different marshalling/unmarshalling library.
The magic of XSLT to the rescue. By running the provided XML through the following XSLT stylesheet I was able to create an XML file that I could then unmarshall correctly.
<?xml version="1.0" encoding="iso-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:cognos="http://developer.cognos.com/schemas/xmldata/1/">
<xsl:output method="xml" version="1.0" encoding="UTF-8" standalone="yes" indent="yes"/>
<xsl:template match="/">
<xsl:element name="DataSet">
<xsl:for-each select="//*[name()='row']">
<xsl:variable name="row" select="position()" />
<xsl:element name="Row">
<xsl:for-each select="//*[name()='item']">
<xsl:variable name="elementName" select="#name" />
<xsl:variable name="index" select="position()" />
<xsl:element name="{translate($elementName,' ','_')}">
<xsl:value-of select="//cognos:row[$row]/cognos:value[$index]" />
</xsl:element>
</xsl:for-each>
</xsl:element>
</xsl:for-each>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
This transformed the XML file as follows
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<DataSet>
<Row>
<EmployeeID>EMP1</EmployeeID>
<firstName>Joe</firstname>
<lastName>Blogs</lastName>
</Row>
<Row>
<EmployeeID>EMP2</EmployeeID>
<firstName>Mary</firstname>
<lastName>Soap</lastName>
</Row>
</DataSet>

Using XSLT to output multiple files

I'm trying to get an example that I found for using XSLT 2.0 to output multiple files working.
Using Saxon B 9.7.0.1 with Java 1.6, I get this error:
C:\Documents and Settings\Administrator\Desktop\saxon>java -jar saxon9.jar -s:input.xml -xsl:transform.xml
Error on line 15 of transform.xml:
java.net.URISyntaxException: Illegal character in path at index 20: file:///C:/Documents
and Settings/Administrator/Desktop/saxon/output1/test1.html

processing /tests/testrun[1]
Transformation failed: Run-time errors were reported
input.xml
<?xml version="1.0" encoding="UTF-8"?>
<tests>

<xsl:template match="/">
<xsl:for-each select="//testrun">
<xsl:variable name="filename"
select="concat('output1/',#run,'.html')" />
<xsl:value-of select="$filename" /> <!-- Creating -->
<xsl:result-document href="{$filename}" format="html">
<html><body>
<xsl:value-of select="#run"/>
</body></html>
</xsl:result-document>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Character 20 in your URI is the first space in "Documents and Settings". As a quick fix, try moving the files to a path without spaces. (Say, "C:\test" or some such.) I suspect the long-term fix is to change your XSLT to encode spaces to %20 before feeding $filename to xsl:result-document, but I'm afraid my XSLT-2.0-fu isn't strong enough to tell you how.
Edit: I haven't tested this, as I don't have an XSLT 2.0 processor handy, but after glancing at the docs, it looks like you want the encode-for-uri function. Something like the following may work for you:
<xsl:result-document href="{fn:encode-for-uri($filename)}" format="html">
I had the same issue with saxon -o: outputfile replacing the spaces with %20..
found out the issue is saxon and java versions.
Linux JAVA 1.7.0_45 : Saxon creates %20
Unix JAVA 1.5.0_61 : SAXON creates %20
Unix JAVA 1.4.2_22 : SAXON Does Not creates %20 directory
