To parse the data, I’ve used
#!/bin/python from BeautifulSoup import BeautifulSoup from os.path import basename, splitext from PIL import Image import glob # Path where the posts are, in markdown format path = "/ruta/ficheros/*.md" # Iterate over all posts for fname in glob.glob(path): # Open the post f = open(fname) # Create a BeautifulSoup object to parse the file soup = BeautifulSoup(f) f.close() # For each img tag: for img in soup.findAll('img'): if img != None: try: if img['src'].startswith("/assets") == True: # Open the image pil = Image.open("/ruta/carpeta/imagenes" + img['src']) # Get its size width, height = pil.size # Modify img tag with image size img['width'] = str(width) + "px" img['height'] = str(height) + "px" except KeyError: pass # Save the updated post with open(fname, "wb") as file: file.write(str(soup))
Hope you find it useful, you can visit the script at github.
