Creating XML With Python
Part 1: xml.dom.minidom Basics
There are many resources out there if you'd like to consume and parse XML with Python. I was looking around the web for resources on producing XML with Python, and I wasn't able to find much. Here is a pretty simple script and its output. It will create a WML document.
from xml.dom.minidom import Document
# Create the minidom document doc = Document()
# Create the <wml> base element wml = doc.createElement("wml") doc.appendChild(wml)
# Create the main <card> element maincard = doc.createElement("card") maincard.setAttribute("id", "main") wml.appendChild(maincard)
# Create a <p> element paragraph1 = doc.createElement("p") maincard.appendChild(paragraph1)
# Give the <p> elemenet some text ptext = doc.createTextNode("This is a test!") paragraph1.appendChild(ptext)
# Print our newly created XML print doc.toprettyxml(indent=" ")
<?xml version="1.0" ?>
This is a test!
As an aside, this XML will probably not parse on a WAP/WML mobile device, as it doesn't have a DOCTYPE.
You can see that creating arbitrary XML with the minidom is nearly trivial. I didn't say intuitive, I said nearly trivial. I'm sure that there are better ways of producing XML, but right now the documentation and tutorials are weak at best. Stay tuned for more.
- Python Documentation: xml.dom.minidom, DOM Objects, DOM Example, minidom and the DOM standard.
- Dive Into Python: XML Processing (Great tutorial on parsing XML)
- Python Web Programming by Steve Holden has some information on producing and consuming XML. I don't own it yet, but I will soon.
