Question

Let’s say I have an existing trivial XML file named ‘MyData.xml’ that contains the following:

<?xml version='1.0' encoding='utf-8' ?> <myElement>foo</myElement> 

I want to change the text value of ‘foo’ to ‘bar’ resulting in the following:

<?xml version='1.0' encoding='utf-8' ?> <myElement>bar</myElement> 

Once I am done, I want to save the changes.

What is the easiest and simplest way to accomplish all this?

Answer 1

Use Python’s minidom

Basically you will take the following steps:

1. Read XML data into DOM object
2. Use DOM methods to modify the document
3. Save new DOM object to new XML document

The python spec should hold your hand rather nicely though this process.
