Hi. I need to write XML files using lxml and Python. However, I can't figure out whether to use a class to do this or a function. The point being, this is the first time I am developing a proper software and deciding where and why to use a class still seems mysterious. I will illustrate my point. For example, consider the following function based code I wrote for adding a subelement to a etree root. from lxml import etree

root = etree.Element('document')

def createSubElement(text, tagText = ""):

etree.SubElement(root, text)

# How do I do this: element.text = tagText

createSubElement('firstChild')

createSubElement('SecondChild')

As expected, the output of this is: <document>

<firstChild/>

<SecondChild/>

</document>

However as you can notice the comment, I have no idea how to do set the text variable using this approach. Is using a class the only way to solve this? And if yes, can you give me some pointers on how to achieve this?
