Efficiently Loop Through 200 XML Files in Python and Save Results to a Single TXT File

Managing a large number of XML files can be daunting. In this guide, we'll explore how to efficiently loop through nearly 200 XML files in a specified folder, apply a function to each file, and save the results into a single TXT file. Whether you’re extracting data or modifying content, we’ll provide you with the tools you need to automate this process using Python.

The Problem

Suppose you have a folder filled with multiple XML files and you want to perform a specific function on each file, and then consolidate all the outputs into one TXT file. For example, you might be using an API to process each XML file and need to extract specific values to summarize in a single text file.

Let’s break down what you'll need to do.

The Solution

Step 1: List All XML Files in a Directory

To start off, you need a way to gather all the XML files within your target directory. In Python, this can be accomplished using the os module. Here’s how you can do it:

Explanation: This code lists all files in the specified directory and filters the list to only include XML files.

Step 2: Modify Your Function

Next, we need to adjust your existing convert() function so that it can accept a filename and process the XML files properly. Here’s how you can redefine the convert() function:

Modifications made:

Accepting xFile as a parameter allows you to use the function more flexibly.

Using with open ensures files are properly closed after their block is executed.

Step 3: Loop Through the Files

Finally, you can loop through each XML file and execute the convert() function for each file. Here’s how it looks:

Step 4: Save the Results in a TXT File

In addition to processing each XML, you'll want to extract the relevant data from resp.xml and write it into a TXT file. Here’s a simple way to do that once you have the data from the API:

Important Notes

Ensure that your specified directory contains only XML files to prevent errors while processing.

Make sure to handle any exceptions for robustness, especially when dealing with file operations and external APIs.

Conclusion

By implementing these steps, you will be able to efficiently process a large number of XML files in Python, applying a function to each and consolidating results into a single TXT file. This approach not only saves time but also minimizes manual effort in file management.

With Python’s powerful libraries at your disposal, this task can be automated with just a few lines of code. Happy coding!
