Hello, It seems that BaseX 12.0 beta 2686758, and later, is tripping on the XSLT transformation that outputs text, not XML. I am using SaxonHE12-5J. Even the following XQuery setting is not helping. declare option output:method 'text'; IMHO, BaseX should read the output:method attribute from an XSLT and handle it properly. method? = "xml" | "html" | "xhtml" | "text" | "json" | "adaptive" | eqname https://qt4cg.org/specifications/xslt-40/Overview.html#id-xsl-output-declaration Below is an easy repro. Process3.xslt is working (xsl:output method="xml") Process2.xslt is NOT working (xsl:output method="text") Error: Stopped at C:/Program Files (x86)/BaseX/src/file, 10/15: [FODC0002] "" (Line 1): Content is not allowed in prolog. XQuery ============= (: Outputs the result as xml. :) declare option output:method 'text';
declare variable $input as xs:string := 'e:\Temp\BaseX_XSLT\Input2.xml';
declare variable $stylesheet as xs:string := 'e:\Temp\BaseX_XSLT\Process2.xslt';

xslt:transform($input, $stylesheet)
input2.xml ============== <dummy>text</dummy> Process3.xslt ================= <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="xml" omit-xml-declaration="yes"/>
	<xsl:template match="/dummy">
		<xsl:copy-of select="."/>
	</xsl:template>
</xsl:stylesheet>
Process2.xslt ================ <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="text" omit-xml-declaration="yes"/>
	<xsl:template match="/dummy">
		<xsl:value-of select="."/>
	</xsl:template>
</xsl:stylesheet>

11.9 (and SaxonHE-J 12.7) has the same issue, and continues to have the issue with the delivery-format option set on transform()
xslt:transform($input, $stylesheet,map{'delivery-format': 'raw'})
xslt:transform($input, $stylesheet,map{'delivery-format': 'serialized'})
xslt:transform($input, $stylesheet,map{'delivery-format': 'document'})
all give the same "not allowed in prolog" result. Since setting the stylesheet to process3.xsl which ought to return
<dummy>text</dummy>
returns text instead, no matter if delivery-format is set or what it's set to if it is set, or if I assign the result to a variable typed item() and return that. -- Graydon

Hi Yitzhak, If your XSLT transformation returns something else than an XML document, you should use xslt:transform-text [1] to receive the generated result as string. Hope this helps, Christian [1] https://docs.basex.org/main/XSLT_Functions#xslt:transform-text

Mr. Grun, The xslt:transform-text() is working for me. Thanks a lot. Regards, Yitzhak Khabinsky

Written for BaseX 11.9. BaseX may have changed since: please check the current documentation.
