I have got below xml which is genrated using xslt function json-to-xml(). I need to update this xml as shown in Result xml using given xpaths. I need the solution in java or xslt. Any help would be much appreciated.

My Try
I have tried converting this xml back to json using xslt function and then used com.jayway.jsonpath Jayway JsonPath library to parse/change values of json on given xpaths. And then finally changed that json again to xml using xslt function. This worked for me like charm !!
But after using this library i started facing issues in my other part of application :( . All the post request with json request body started giving 400 error. The error was "Error 400 The request sent by the client was syntactically incorrect" . I couldn't figure out the issue and may be it was due to different jar conficts.
So I am trying some other way to work. Any other library like Jayway JsonPath? Or any other solution/Suggestion will help alot.
One approach given XSLT 3 might be to transform those paths you have into XSLT 3 match templates and then create a stylesheet you can execute with the transform function (https://www.w3.org/TR/xpath-functions/#func-transform):
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

exclude-result-prefixes="xs"

<xsl:namespace-alias stylesheet-prefix="axsl" result-prefix="xsl"/>
<xsl:output method="xml" indent="yes"/>
<xsl:param name="paths" as="xs:string">/Response/Payload/root/cars[2]/strength=999
/Response/Payload/root/bikes[1]/model=2019

/Response/Headers/Status-Code=400</xsl:param>
<xsl:param name="path-sequence" as="xs:string*" select="tokenize($paths, '\s+')!normalize-space()"/>
<xsl:variable name="stylesheet">

<axsl:template>
<xsl:attribute name="match">

</xsl:attribute>
<axsl:copy>
<axsl:copy-of select="#*"/>
<xsl:value-of select="substring-after($steps[last()], '=')"/>
</axsl:copy>
</axsl:template>
</xsl:for-each>
</axsl:stylesheet>
</xsl:variable>
<xsl:template match=".[not(contains(., '[')) and not(contains(., '='))]" mode="step">
<xsl:if test="position() gt 1">/</xsl:if>
<xsl:sequence select="'*[#key = ''' || . || ''']'"/>
</xsl:template>
<xsl:template match=".[contains(., '=')]" mode="step">
<xsl:if test="position() gt 1">/</xsl:if>
<xsl:sequence select="'*[#key = ''' || substring-before(., '=') || ''']'"/>
</xsl:template>
<xsl:template match=".[contains(., '[')]" mode="step">
<xsl:if test="position() gt 1">/</xsl:if>
<xsl:sequence select="'*[#key = ''' || substring-before(., '[') || ''']/*[' || replace(., '^[^\[]+\[([0-9]+)\]', '$1') || ']'"/>
</xsl:template>
<xsl:template match="/">
<xsl:sequence select="transform(map {
'source-node' : .,
'stylesheet-node' : $stylesheet
})?output"/>
</xsl:template>
</xsl:stylesheet>
At https://xsltfiddle.liberty-development.net/jyyiVhv/1 I get the wanted result
<?xml version="1.0" encoding="UTF-8"?>
<map xmlns="http://www.w3.org/2005/xpath-functions">

that way although I had to adapt the paths including bikes to bikes[1].

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).
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>
I struggling with XSLT transformer mediator using XSLT mediator in wso2 esb 4.8.1.

</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.?
i want to create .xml file into csv file using camel. here is my code
CamelContext context = new DefaultCamelContext();
from("file://Input?fileName=test.xml").marshal().csv().to("file://test?fileName=test.csv");
context.start();
But its't creating any file in desired folder "test".
Please spend just a bit more time on the Camel docs, and try out the examples, and read the FAQ. And the introduction articles and whatnot.
The code above isn't even valid, as you would need to put it inside a RouteBuilder.
Also when you start CamelContext, read the javadoc of the start method. And read this FAQ
http://camel.apache.org/running-camel-standalone-and-have-it-keep-running.html
Also Camel offers a tracer so you can see the message flow as the messages are being processed. The tracer will be default log this at INFO level to the logger.
http://camel.apache.org/tracer
Here is a sample using camel
<camelContext xmlns="http://camel.apache.org/schema/spring">
<route>
<from uri="file:src/xmldata?noop=true"/>
<to uri="xslt:file:src/main/fruits.xslt"/>
<to uri="file://TESTOUT?fileName=output.csv"/>
</route>
</camelContext>
sample xml file in src/xmldata folder
<AllFruits xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- All fruits below. -->
<Fruit>
<FruitId>Bannana</FruitId>
<FruitColor>Yellow</FruitColor>
<FruitShape>Moon</FruitShape>
<Customer>
<Name>Joe</Name>
<NumberEaten>5</NumberEaten>
<Weight>2.6</Weight>
</Customer>
<Customer>
<Name>Mark</Name>
<NumberEaten>8</NumberEaten>
<Weight>5.0</Weight>
</Customer>
</Fruit>
</AllFruits>
src/main/fruits.xslt
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="text" encoding="ISO-8859-1" />
<xsl:variable name="newline" select="'

<xsl:template match="Fruit">

In the XML example below, using a java parser how to keep the content under the tag AND followed by center and remove everything else?
The tag might have other instances when is followed by other tags than center, and those has to be discarded.
<xml>
<A>
<B>
.
.
.
<parameter>
<parameterid>center</parameterid>
<name>Center</name>
<keyframe>
<when>1</when>
<value>
<horiz>100</horiz>
<vert>100</vert>
</value>
</keyframe>
<keyframe>
<when>2</when>
<value>
<horiz>150</horiz>
<vert>150</vert>
</value>
</keyframe>
</parameter>
<parameter>
...
</parameter>
<parameter>
...
</parameter>
.
.
.
</B>
</A>
</xml>
So the output will look like:
<parameter>
<parameterid>center</parameterid>
<name>Center</name>
<keyframe>
<when>1</when>
<value>
<horiz>100</horiz>
<vert>100</vert>
</value>
</keyframe>
<keyframe>
<when>2</when>
<value>
<horiz>150</horiz>
<vert>150</vert>
</value>
</keyframe>
</parameter>
Please advise. Thanks!
You can use Java Regexp to remove unneeded content, and then parse only needed part f.e.
String sourceXML = readFileToString("source.xml")
final Pattern pattern = Pattern.compile(".*(<parameter>.+</parameter>).*",Pattern.DOTALL);
Matcher matcher = pattern.matcher(sourceXML);
if (matcher.find()) {
String xmlToParse = matcher.group(0);
someDomOrSaxParser.parseFromString(xmlToParse)
}else
System.out.println("NO MATCH");
This would be a good job for an XSLT stylesheet.
This stylesheet:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|#*">
<xsl:apply-templates select="node()|#*"/>
</xsl:template>
<xsl:template match="parameter[parameterid='center']">
<xsl:copy-of select="."/>
</xsl:template>
</xsl:stylesheet>
applied to the input in the question, produces the following output:
<parameter>
<parameterid>center</parameterid>
<name>Center</name>
<keyframe>
<when>1</when>
<value>
<horiz>100</horiz>
<vert>100</vert>
</value>
</keyframe>
<keyframe>
<when>2</when>
<value>
<horiz>150</horiz>
<vert>150</vert>
</value>
</keyframe>
</parameter>
