I am trying to transform an XML schema with XSLT 3.0 with Saxon 9.9 HE into a JSON. The transformation is working. However, when I output the value of an attribute it is coming with a line break before and after the name. The XSD fragment is below:

    <group name="imapAttachmentDownloaderGroup">

    <annotation>

        <documentation>

            Configuration block definitions for IMAP attachment downloader delegate. It contains all the configuration

            block definitions that are required to configure the delegate successfully.

        </documentation>

    </annotation>

    <sequence>

        <element name="IMAPConnectorConfig">

            <complexType>

                <attribute name="imapHost" use="required" type="string">

                    <annotation>

                        <documentation>

                            This configuration block deals with the IMAP server name or IP address to where the 

                            connection is to be made to download the attachments.

                            Example: "outlook.office365.com" or "40.100.137.66"

                        </documentation>

                    </annotation>

                </attribute>

                <attribute name="imapPort" use="required" type="int">

                    <annotation>

                        <documentation>

                            The port to use to connect to the server, defaults to 993.

                            Example: "993"

                        </documentation>

                    </annotation>

                </attribute>

....

The SXL is as below:

<?xml version="1.0" encoding="UTF-8"?>

<stylesheet version="3.0" 

            xmlns="http://www.w3.org/1999/XSL/Transform"

                  <for-each select="child::xsi:sequence/child::xsi:element">

                    ,'<value-of select="attribute::name"/>':{

                        <for-each select="child::xsi:complexType/child::xsi:attribute">

                            <choose>

                                <when test="position()=last()">'name':'<value-of select="attribute::name"/>'</when>

                                <otherwise>'name':'<value-of select="attribute::name"/>',</otherwise>

                            </choose>

                        </for-each>

                        <for-each select="child::xsi:complexType/child::xsi:attributeGroup">

                            <value-of select="attribute::ref"/>

                        </for-each>

                                                            }

                  </for-each>

        }



    <!-- <apply-templates select="attribute::name"/> -->

</template>

The output is:

    {'groupName':'

imapAttachmentDownloaderGroup

'

,    '

IMAPConnectorConfig

':{

'name':'

imapHost

',

'name':'

imapPort

',

'name':'

sslEnabled

',

'name':'

startTLSEnabled

',

'name':'

imapUser

',

'name':'

imapPassword

',

'name':'

credentialId

I have tried all the mechanisms that I could find in the posts assigning it to variable, normalize-space, normalize-space with string() with data(). Nothing seems to be working. Any help would be sincerely appreciated.

=== Including complete example ===

XSL (removed all the comments and other elements):

<?xml version="1.0" encoding="UTF-8"?>

<stylesheet version="3.0" 

            xmlns="http://www.w3.org/1999/XSL/Transform"

            xmlns:xsi="http://www.w3.org/2001/XMLSchema"

            xmlns:tns="http://www.proviseconsulting.com/ProcessConfig"

            xmlns:saxon="http://saxon.sf.net/"

            xsi:schemaLocation="http://www.w3.org/1999/XSL/Transform 

                                https://www.w3.org/2007/schema-for-xslt20.xsd">



<mode on-no-match="shallow-skip"/>

<output method="text" encoding="utf-8" indent="no" media-type="application/json" normalization-form="true"/>

<strip-space elements="*" />



<param name="delegateGroupName" required="yes"/>



<template match="/child::xsi:schema/child::xsi:group[attribute::name=$delegateGroupName]">

    <text>{"groupName":"</text><value-of select="attribute::name/normalize-space()"/><text>"}</text>

</template>

=== Output ===

{"groupName":"

imapAttachmentDownloaderGroup

"}

The input XSD remains the same. The Java code is as below:

        String xsdFilePath="file:///D:/workspaces/mtplatform/PlatformManual_V1/PlatformManual/ProcessConfiguration/ProcessConfiguration.xsd";

    String xslFilePath="file:///D:/workspaces/mtplatform/PlatformManual_V1/PlatformManual/ProcessConfiguration/ProcessConfiguration.xsl";



    Processor processor=new Processor(false);

    XdmNode node=processor.newDocumentBuilder().build(new File(new URI(xsdFilePath)));

    XsltCompiler xsltCompiler=processor.newXsltCompiler();

    //xsltCompiler.setParameter(new QName("delegateGroupName"), XdmValue.makeValue("imapAttachmentDownloaderGroup"));



    StreamSource xsdSource=new StreamSource(new FileInputStream(new File(new URI(xsdFilePath))));

    StreamSource xslSource=new StreamSource(new FileInputStream(new File(new URI(xslFilePath))));



    XsltExecutable compiledXSL=xsltCompiler.compile(xslSource);

    Xslt30Transformer xslTransformer=compiledXSL.load30();



    HashMap<QName, XdmValue> parameterMap=new HashMap<>();

    parameterMap.put(new QName("delegateGroupName"), XdmValue.makeValue("imapAttachmentDownloaderGroup"));

    xslTransformer.setStylesheetParameters(parameterMap);

    XdmValue output=xslTransformer.applyTemplates(node);



    System.out.println(output.toString());

In general, to control the text output, you can use the xsl:text element https://www.w3.org/TR/xslt-30/#xsl-text in the form

 <for-each select="child::xsi:sequence/child::xsi:element">

                <text>,'</text>

                <value-of select="attribute::name"/>

                <text>':{</text>

Furthermore, if you use Xslt30Transformer and want a serialized result in the form of text, like JSON, where the format is defined by the xsl:output in your XSLT, then you should use an overload of applyTemplates allowing you to use a Serializer as the Destination, i.e. http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#applyTemplates-net.sf.saxon.s9api.XdmValue-net.sf.saxon.s9api.Destination- with a Serializer created by the Xslt30Transformer (http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#newSerializer-java.io.OutputStream-), so in the simple case of testing the result with System.out you would use

Serializer serializer =  xslTransformer.newSerializer(System.out);

xslTransformer.applyTemplates(node, serializer);

In your Java case you have used the overload to create an XdmValue, take notice that its documentation http://saxonica.com/html/documentation/javadoc/net/sf/saxon/s9api/Xslt30Transformer.html#applyTemplates-net.sf.saxon.s9api.XdmValue- says it returns

the raw result of applying templates to the supplied selection value,
without wrapping in a document node or serializing the result

As you have found according to your comments, if you have an XdmValue and want to serialize it in a controlled way, you are better off using the serializeXdmValue method of a Serializer set up as needed instead of simply calling toString on the XdmValue.
