Confused as to use a class or a function: Writing XML files using lxml and Python
- by PulpFiction
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?
