    <p>I'm attempting to write contents from <code>xml.dom.minidom</code> object to file. The simple idea is to use 'writexml' method:</p> <pre><code>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() </code></pre> <p>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:</p> <pre><code>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() </code></pre> <p>This results in the following error:</p> <pre><code>Traceback (most recent call last): File "D:\Projects\Semio\semioparser.py", line 45, in &lt;module&gt; 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) </code></pre> <p>How do I write an XML text to file? What is it I'm missing?</p> <p><strong>EDIT</strong>. Error is fixed by adding decode statement: <code>f.write(xmldoc.toxml("utf-8").decode("utf-8"))</code> But russian symbols are still corrupted.</p> <p>The text is not corrupted when viewed in an interpreter, but when it's written in file.</p>

    1. COJust a thought: Are you sure you are not viewing the file incorrectly? Maybe the reader is expecting another encoding than utf-8 and it just looks borked.

    2. CO@Nubsis That is exactly what was going on. The viewer has been expecting ASCII encoding. I'll keep the thread though because using .decode() was the problem too. Thanks!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
