我的轉換樣式表檔案包含：
<?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"/>

<cities>
<xsl:for-each select="cities/country">
<city name="{@capital}" isCapital="true"/>
</xsl:for-each>
</cities>
</xsl:template>
</xsl:stylesheet>
我的python代碼：
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)
# create individual raw xmls
cnt = 0
for child in children:
cnt = cnt 1
childroot = ET.Element("cities")
childroot.append(child)
tempfile_tree = ET.ElementTree(childroot)
# tempfile = "C:\\pythonProject\\stackoverflow\\tmp.xml"
# tempfile = "C:\\gaga\\tmp.xml"
# tempfile = os.path.abspath("tmp.xml")
tempfile = "tmp.xml"
transformedfile = f"output_{cnt}.xml"
with open(tempfile, 'wb') as f:
tempfile_tree.write(f, encoding='utf-8', xml_declaration=True)
try:
with PySaxonProcessor(license=False) as proc:
proc.set_cwd(os.getcwd())
xsltproc = proc.new_xslt30_processor()
xsltproc.transform_to_file(source_file=tempfile,
stylesheet_file="transformer.xsl",
output_file=transformedfile)
print(f"{transformedfile} has been created.")
except Exception as e:
print(e)
if __name__ == "__main__":
main()
我的問題
我有進口的薩克森。我正在嘗試在回圈中運行 saxonc 的 transform_to_file() 。我無法獲得轉換后的輸出檔案。根據我為 tempfile 設定的內容，我得到
# I/O error reported by XML parser processing C:\pythonProject\stackoverflow\?╚╒E ?:
# unknown protocol: c. Caused by java.net.MalformedURLException: unknown protocol: c
或者
Content is not allowed in prolog
(this is definitely not the case, I checked the tempfile with a hexeditor)
或沒有錯誤但輸出檔案僅包含：
# <?xml version="1.0" encoding="UTF-8"?>
# <cities/>
而且輸出正確（但我不能再復制它了）。
注意：我在安裝 python 3.10 時禁用了 MAX_PATH。注意：將 Pycharm 與詩歌 venv 一起使用

使用SaxonC 11.3，我設法運行了上面的 python 腳本，并進行了微小的更改：
from saxonpy import PySaxonProcessor
替換為：
from saxonc import *
我得到了輸出：
starting code...
output_1.xml has been created.
output_2.xml has been created.
output_3.xml has been created.
這些檔案都有以下內容：
<?xml version="1.0" encoding="UTF-8"?>
<cities/>
當我解決方法時，我替換transform_to_file為transform_to_string：
valueStr = xsltproc.transform_to_string(source_file=tempfile,
stylesheet_file="transformer.xsl")
#output_file=transformedfile)
print(valueStr)
這確實會產生正確的輸出：
starting code...
source in transformFiletoString=tmp.xml stylsheet=transformer.xsl
<?xml version="1.0" encoding="UTF-8"?>
<cities>
<city name="Copenhagen" isCapital="true"/>
</cities>
output_1.xml has been created.
<?xml version="1.0" encoding="UTF-8"?>
<cities>
<city name="Berlin" isCapital="true"/>
</cities>
output_2.xml has been created.
<?xml version="1.0" encoding="UTF-8"?>
<cities>
<city name="Paris" isCapital="true"/>
</cities>
output_3.xml has been created.

使用 Apply_templates_returning_file() 它可以作業：

print('starting code...')

proc.set_cwd(os.getcwd())
xsltproc = proc.new_xslt30_processor()
xslt30_transformer = xsltproc.compile_stylesheet(stylesheet_file="transformer.xsl")
cnt = 0
for child in children:
cnt = cnt 1
childroot = ET.Element("cities")
childroot.append(child)
tempfile_tree = ET.ElementTree(childroot)
tempfile = "tmp_1234567890ABCDEFGHIJKLMNOP.xml"
transformedfile = f"output_{cnt}.xml"
with open(tempfile, 'wb') as f:
