Writing XML to file corrupts files in python
I'm attempting to write contents from xml.dom.minidom
object to file. The simple idea is to use 'writexml' method:
import codecs
def write_xml_native():
# Building DOM from XML
xmldoc = minidom.parse('semio2.xml')
f = codecs.open('codified.xml', mode='w', encoding='utf-8')
# Using native writexml() method to write
xmldoc.writexml(f, encoding="utf=8")
f.close()
The problem is that it corrupts the non-latin-encoded text in the file. The other way is to get the text string and write it to file explicitly:
def write_xml():
# Building DOM from XML
xmldoc = minidom.parse('semio2.xml')
# Opening file for writing UTF-8, which is XML's default encoding
f = codecs.open('codified3.xml', mode='w', encoding='utf-8')
# Writing XML in UTF-8 encoding, as recommended in the documentation
f.write(xmldoc.toxml("utf-8"))
f.close()
This results in the following error:
Traceback (most recent call last):
File "D:\Projects\Semio\semioparser.py", line 45, in <module>
write_xml()
File "D:\Projects\Semio\semioparser.py", line 42, in write_xml
f.write(xmldoc.toxml(encoding="utf-8"))
File "C:\Python26\lib\codecs.py", line 686, in write
return self.writer.write(data)
File "C:\Python26\lib\codecs.py", line 351, in write
data, consumed = self.encode(object, self.errors)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xd0 in position 2064: ordinal not in range(128)
How do I write an XML text to file? What is it I'm missing?
EDIT. Error is fixed by adding decode statement:
f.write(xmldoc.t开发者_开发技巧oxml("utf-8").decode("utf-8"))
But russian symbols are still corrupted.
The text is not corrupted when viewed in an interpreter, but when it's written in file.
Hmm, though this should work:
xml = minidom.parse("test.xml")
with codecs.open("out.xml", "w", "utf-8") as out:
xml.writexml(out)
you may alternatively try:
with codecs.open("test.xml", "r", "utf-8") as inp:
xml = minidom.parseString(inp.read().encode("utf-8"))
with codecs.open("out.xml", "w", "utf-8") as out:
xml.writexml(out)
Update: In case you construct xml out of string object, you should encode it before passing to minidom parser, like this:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import codecs
import xml.dom.minidom as minidom
xml = minidom.parseString(u"<ru>Тест</ru>".encode("utf-8"))
with codecs.open("out.xml", "w", "utf-8") as out:
xml.writexml(out)
Try this:
with open("codified.xml", "w") as f:
f.write(xmldoc.toxml("utf-8").decode("utf-8"))
This works for me (under Python 3, though).
