Transforming Raw Data into a Structured XML Document in Python

The Problem: Organizing Raw Data

In many cases, raw data files may not have the best structure for use in applications. In our example, we have a text file containing item IDs, names, and their respective parent IDs.

For example, consider the following text structure:

Here, items such as "Ac_05" are children of "Ac", and "Ac_05_00" is a child of "Ac_05". The last item "Ac_15" also needs to be inserted as a child under "Ac". Your goal is to convert this structure into XML while ensuring that each element nests correctly under its parent as designated by the parent ID.

The Solution: Building the XML Structure

Step 1: Preparing Your Data Structure

We'll define lists for our IDs, names, and parent IDs, and initialize the root XML element.

Step 2: Dynamically Creating Child Elements

In this step, a dictionary will be used to keep track of all the children elements of each item. This allows us to append child elements to their corresponding parents correctly.

Step 3: Saving the XML Document

Once we have constructed the XML tree, we can save it to a file.

Final Output

The resulting XML structure will look like this:
