Create XML file with python?
Question: Here is my code:

    
    
    import xml.etree.ElementTree as ET
    
    root = ET.Element("rss", version="2.0", xmlns:excerpt="http://wordpress.org/export/1.2/excerpt/", xmlns:content="http://purl.org/rss/1.0/modules/content/", xmlns:wfw="http://wellformedweb.org/CommentAPI/", xmlns:dc="http://purl.org/dc/elements/1.1/", xmlns:wp="http://wordpress.org/export/1.2/")
    
    ET.dump(root)
    

This is xml file i am trying to create:

    
    
    <rss version="2.0"
        xmlns:excerpt="http://wordpress.org/export/1.2/excerpt/"
        xmlns:content="http://purl.org/rss/1.0/modules/content/"
        xmlns:wfw="http://wellformedweb.org/CommentAPI/"
        xmlns:dc="http://purl.org/dc/elements/1.1/"
        xmlns:wp="http://wordpress.org/export/1.2/"
    >
    

this is very basic part of actual xml file but i am unable to correctly create
it with elementtree. Until version number it works correctly but when i add
"xmlns:something" it does not work. I am very new to xml so i have no idea
even google is not able to help me understand.

**NOTE: Please do tell me if lxml is more easy or this ElementTree. Because I
have previously used lxml for xpath and css elements.**


Answer: Python identifiers are not allowed to have colons inside. ElementTree allows
to pass an attribute dictionary by the key `attrib`:

`ET.element("rss", attrib={"xmlns:excerpt":"http..."}`
