This seems to be answered by @alinaOS in SaxonC 11.1 transform_to_file Produces No Output File but doesn't answer their question. It might be more suitable here.
My workaround doesn't work either (see saxonc's transform_to_file(), executed in a loop, doesn't transform but gives non-sensical errors or partial output)
I'm trying to run saxon-c's transform_to_file() with an xml string as input (not a file).
xsltproc.transform_to_file(xdm_node=xml_doc,
stylesheet_file="transformer.xsl",
output_file=transformedfile)
I get no errors but also no output file.
My transformation stylesheet file contains:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
<cities>
<xsl:for-each select="cities/country">
<city name="{@capital}" isCapital="true"/>
</xsl:for-each>
</cities>
</xsl:template>
</xsl:stylesheet>
My python code:
import os
import xml.etree.ElementTree as ET
from saxonpy import PySaxonProcessor
def main():
print('starting code...')
source_XML = '''
<data>
<country name="Denmark" capital="Copenhagen"/>
<country name="Germany" capital="Berlin"/>
<country name="France" capital="Paris"/>
</data>
'''
parentroot = ET.fromstring(source_XML)
children = list(parentroot)
cnt = 0
for child in children:
cnt = cnt 1
childroot = ET.Element("cities")
childroot.append(child)
temp_tree = ET.ElementTree(childroot)
# has to be unicode for proc.parse_xml()
xml_str = ET.tostring(temp_tree.getroot(), encoding='unicode', method='xml')
transformedfile = f"output_{cnt}.xml"
try:
with PySaxonProcessor(license=False) as proc:
proc.set_cwd(os.getcwd())
xsltproc = proc.new_xslt30_processor()
xml_doc = proc.parse_xml(xml_text=xml_str)
xsltproc.xsltproc.transform_to_file(xdm_node=xml_doc,
stylesheet_file="transformer.xsl",
output_file=transformedfile)
print(f"ended. But where is {str(proc.cwd)}\\{transformedfile}?")
except Exception as e:
print(f"exception occured: {e}")
if __name__ == "__main__":
main()
