Hello,
Here is an example code of xml writer in Python+PythonNet, Ironpython
and Boo. The codes look very similar.

Regards,
Srijit

Python + PythonNet:

import CLR
import CLR.System
from CLR.System import Console as CLR_Console
import CLR.System.Xml as CLR_Xml

true = 1
false = 0
filename = "test1.xml"
writer = CLR_Xml.XmlTextWriter(filename, None);
#~ Use indenting for readability.
writer.Formatting = CLR_Xml.Formatting.Indented;

writer.WriteComment("XML in Boo Language");

#~ Write an element (this one is the root).
writer.WriteStartElement("EducationalCentres");

#~ Write the namespace declaration.
writer.WriteAttributeString("xmlns", "schname", None,
"urn:schoolnames");

writer.WriteStartElement("School");

#~ Lookup the prefix and then write the ISBN attribute.
prefix = writer.LookupPrefix("urn:schoolnames");
writer.WriteStartAttribute(prefix, "NAME", "urn:schoolnames");
writer.WriteString("ABCD International School");
writer.WriteEndAttribute();     

#~ Write the title.
writer.WriteStartElement("city");
writer.WriteString("Madurai");
writer.WriteEndElement();
  
#~ Write the price.
writer.WriteElementString("Students", "500");

#~ Write the style element.
writer.WriteStartElement(prefix, "Syllabus", "urn:schoolnames");
writer.WriteString("IGCSE");
writer.WriteEndElement();

#~ Write the end tag for the book element.
writer.WriteEndElement();

#~ Write the close tag for the root element.
writer.WriteEndElement();
 
#~ Write the XML to file and close the writer.
writer.Flush();
writer.Close();

#~ Read the file back in and parse to ensure well formed XML.
doc = CLR_Xml.XmlDocument();
#~ Preserve white space for readability.
doc.PreserveWhitespace = true;
#~ Load the file
doc.Load(filename);

#~ Write the XML content to the console.
CLR_Console.Write(doc.InnerXml);


Ironpython:

from System import *
from System.Xml import *

true = 1
false = 0
filename = "test1.xml"
writer = XmlTextWriter(filename, None);
#~ Use indenting for readability.
writer.Formatting = Formatting.Indented;

writer.WriteComment("XML in Boo Language");

#~ Write an element (this one is the root).
writer.WriteStartElement("EducationalCentres");

#~ Write the namespace declaration.
writer.WriteAttributeString("xmlns", "schname", None,
"urn:schoolnames");

writer.WriteStartElement("School");

#~ Lookup the prefix and then write the ISBN attribute.
prefix = writer.LookupPrefix("urn:schoolnames");
writer.WriteStartAttribute(prefix, "NAME", "urn:schoolnames");
writer.WriteString("ABCD International School");
writer.WriteEndAttribute();     

#~ Write the title.
writer.WriteStartElement("city");
writer.WriteString("Madurai");
writer.WriteEndElement();
  
#~ Write the price.
writer.WriteElementString("Students", "500");

#~ Write the style element.
writer.WriteStartElement(prefix, "Syllabus", "urn:schoolnames");
writer.WriteString("IGCSE");
writer.WriteEndElement();

#~ Write the end tag for the book element.
writer.WriteEndElement();

#~ Write the close tag for the root element.
writer.WriteEndElement();
 
#~ Write the XML to file and close the writer.
writer.Flush();
writer.Close();

#~ Read the file back in and parse to ensure well formed XML.
doc = XmlDocument();
#~ Preserve white space for readability.
doc.PreserveWhitespace = true;
#~ Load the file
doc.Load(filename);

#~ Write the XML content to the console.
Console.Write(doc.InnerXml);


Boo:

import System
import System.Xml from System.Xml

filename = "test1.xml"
writer = XmlTextWriter(filename, null);
#~ Use indenting for readability.
writer.Formatting = Formatting.Indented;

writer.WriteComment("XML in Boo Language");

#~ Write an element (this one is the root).
writer.WriteStartElement("EducationalCentres");

#~ Write the namespace declaration.
writer.WriteAttributeString("xmlns", "schname", null,
"urn:schoolnames");

writer.WriteStartElement("School");

#~ Lookup the prefix and then write the ISBN attribute.
prefix = writer.LookupPrefix("urn:schoolnames");
writer.WriteStartAttribute(prefix, "NAME", "urn:schoolnames");
writer.WriteString("ABCD International School");
writer.WriteEndAttribute();     

#~ Write the title.
writer.WriteStartElement("city");
writer.WriteString("Madurai");
writer.WriteEndElement();
  
#~ Write the price.
writer.WriteElementString("Students", "500");

#~ Write the style element.
writer.WriteStartElement(prefix, "Syllabus", "urn:schoolnames");
writer.WriteString("IGCSE");
writer.WriteEndElement();

#~ Write the end tag for the book element.
writer.WriteEndElement();

#~ Write the close tag for the root element.
writer.WriteEndElement();
 
#~ Write the XML to file and close the writer.
writer.Flush();
writer.Close();

#~ Read the file back in and parse to ensure well formed XML.
doc = XmlDocument();
#~ Preserve white space for readability.
doc.PreserveWhitespace = true;
#~ Load the file
doc.Load(filename);

#~ Write the XML content to the console.
Console.Write(doc.InnerXml);
