Parse Error when first line is blank

[Myriades-ll]

Hi. parse error is thrown when first line is blank or is comment the xml content:

<!-- first line is blank or have a comment, like this one -->
<?xml version="1.0" encoding="UTF-8"?>
<rss>
	<item>foo</item>
	<item>bar</item>
	<item>baz</item>
</rss>

the error:

  File "/usr/local/lib/python3.8/dist-packages/encoder.py", line 93, in parse
    EL = ET.fromstring(xml)
  File "/usr/lib/python3.8/xml/etree/ElementTree.py", line 1320, in XML
    parser.feed(text)
xml.etree.ElementTree.ParseError: XML or text declaration not at start of entity: line 2, column 0

Removing the blank line or comment solves the problem.

Regards.
