如何批量处理列表中XML文件以生成无空白行的新文件？

Got it, let's get that batch processing working for you! Your single-file logic is solid—we just need to wrap it in a loop that iterates over every XML file in your directory, and handle paths dynamically so each file gets processed correctly.

Here's the complete working code: #

import os

# Define your input and output directories
input_dir = r'C:\Users\Max12\Desktop\xml\pdfminer\UiPath\output'
output_dir = r'C:\Users\Max12\Desktop\xml\pdfminer\UiPath\out'

# Ensure the output directory exists (creates it if it doesn't)
os.makedirs(output_dir, exist_ok=True)

# Loop through all files in the input directory
for filename in os.listdir(input_dir):
    # Only process XML files to avoid handling non-XML items
    if filename.endswith('.xml'):
        # Build full paths for input and output files (safer than hardcoding)
        input_file_path = os.path.join(input_dir, filename)
        output_file_path = os.path.join(output_dir, filename)
        
        # Apply your empty-line removal logic to each file
        with open(input_file_path, 'r') as infile, open(output_file_path, 'w') as outfile:
            for line in infile:
                # Skip lines that are empty after stripping whitespace
                if not line.strip():
                    continue
                outfile.write(line)
        
        # Optional: Print status to track progress
        print(f"Successfully processed: {filename}")

Key improvements over your single-file code: #

• Dynamic path handling: Using os.path.join() ensures your code works across different operating systems (no more worrying about backslashes vs slashes) and avoids errors from hardcoded filenames.
• Output directory safety: os.makedirs(..., exist_ok=True) creates the output folder if it doesn't exist, so you won't get a "file not found" error when trying to write the cleaned files.
• File filtering: The filename.endswith('.xml') check ensures we only process XML files, ignoring any other files or subdirectories that might end up in your input folder.
• Batch iteration: The loop runs through every qualifying file, so you'll get 4 cleaned XML files (one for each input file) in your out directory, each with no empty lines.

Just run this code, and it'll handle all your XML files automatically!
