Description
I am not sure whether I have hit a bug or am simply not finding the wrong way from the Python API to set an XSLT parameter to a sequence of strings; the Python code is e.g.
from saxonche import *
with PySaxonProcessor(license=False) as saxon_proc:
xslt30_processor = saxon_proc.new_xslt30_processor()
element_names = ['foo', 'foobar']
xslt_param = PyXdmValue()
for name in element_names:
xslt_param.add_xdm_item(saxon_proc.make_string_value(name))
xslt30_processor.set_parameter('cdata-tag-names', xslt_param)
xslt30_processor.transform_to_file(source_file='sample2.xml', stylesheet_file='serialize-wrap-in-cdata1.xsl', output_file='result-sample2.xml')
XSLT is
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="#all"
expand-text="yes"
version="3.0">
<xsl:param name="cdata-tag-names" as="xs:string*" static="yes" select="'tag'"/>
<xsl:mode on-no-match="shallow-copy"/>
<xsl:output method="xml" _cdata-section-elements="{$cdata-tag-names}"/>
<xsl:template _match="{$cdata-tag-names => string-join(' | ')}">
<xsl:copy>{serialize(node())}</xsl:copy>
</xsl:template>
</xsl:stylesheet>
XML is
<?xml version="1.0" encoding="utf-8" ?>
<root>
<foo>
some data
<!-- some data2 -->
<!-- some data2 -->
some data
</foo>
<bar>
some data
<!-- some data2 -->
<!-- some data2 -->
some data
</bar>
<foobar>
some data
<!-- some data2 -->
<!-- some data2 -->
some data
</foobar>
</root>
Error I get:
