Do you check for nullptr on the File variable?

I managed to see the problem is because you have not set a source document or match selection.

The following bit of code will help:

if (File == nullptr) {
        if (xslte->exceptionOccurred()) {
            cout << xslte->getErrorMessage() << endl;
        }
    }

I get the following error message:

net.sf.saxon.s9api.SaxonApiException : No initial match selection supplied

So I added the following lines before the transformToString call:

    xslte->setInitialMatchSelection(xmlfile);
    xslte->setGlobalContextItem(xmlfile);

Now getting the following error:

Error in xsl:result-document/@href on line 6 column 44 of file:///location/:
  SXRD0002  The system identifier of the principal output file is unknown
  In template rule with match="/" on line 4 of file:///location/
     invoked by xsl:result-document at file:///location/#6
  In template rule with match="/" on line 4 of file:///location/
net.sf.saxon.s9api.SaxonApiException : The system identifier of the principal output file is unknown

My last error is because I have loaded stylesheet and xml as strings, but I think you will not see this error

I confirm I get the output file:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<result>
   <value>You put a 5</value>
</result>

BTW if you run into the error SXRD0002 The system identifier of the principal output file is unknown then you need the following code:

xslte->setBaseOutputURI("file:///location/");

As an alternative to comment #3 it is possible to directly pass the source on the transformToString methodf:

xslte-> transformToString(xmlfile);

It seems still a bit confusing that transformToString works fine without setting xslte->setBaseOutputURI("file:///location/"); in code not using xsl:result-document e.g. with

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" expand-text="yes">
	<xsl:output method="xml" encoding="utf-8" standalone="yes" indent="yes"/>

	<xsl:template match="/">
		<xsl:message>producing sheet</xsl:message>
		<main-result>
			<tested-at>{current-dateTime()}</tested-at>
			<static-base-uri>{static-base-uri()}</static-base-uri>
		</main-result>
		<!--<xsl:result-document href="output.xml">
			<result>
				<value>
					You put a <xsl:value-of select="/xml/value"/>
				</value>
			</result>
		</xsl:result-document>-->
	</xsl:template>
</xsl:stylesheet>

but as soon as I uncomment the use of xsl:result-document with the relative URI SaxonC gives the

SXRD0002  The system identifier of the principal output file is unknown
  In template rule with match="/" on line 4 of result-document-test2.xsl

Perhaps that just needs better documentation/explanation in the documentation that the use of the transformToString together with xsl:result-document requires an explicit setting of the base output URI if relative URIs are used in the XSLT. But it kind of feels that the base output uri might be available from the stylesheet's base URI, as it seems to be if the target is a transformToFile.

Also using "xsl:result-document" , it outputs the xml files into the same directory as the xslt file that used "result-document" , how to I tell it where to output the files .

The result-document will be saved relative to the location set using setBaseOutputURI.

This is not ideal from a users perspective as they don't have access to the Destination class as in java. I am raising separate bug issue
