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-declara...
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, $stylesheet)
input2.xml ============== <dummy>text</dummy>
Process3.xslt ================= <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform%22%3E <xsl:output method="xml" omit-xml-declaration="yes"/> <xsl:template match="/dummy"> <xsl:copy-of select="."/> </xsl:template> </xsl:stylesheet>
Process2.xslt ================ <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform%22%3E <xsl:output method="text" omit-xml-declaration="yes"/> <xsl:template match="/dummy"> <xsl:value-of select="."/> </xsl:template> </xsl:stylesheet>
11.9 (and SaxonHE-J 12.7) has the same issue, and continues to have the issue with the delivery-format option set on transform()
xslt:transform($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.

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

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