svg_id.py

import string

svgFile = 'pattern.svg'
svgFileNew = 'pattern1.svg'

with open(svgFile) as f:

	thefile = open(svgFileNew, 'w')
	lines = f.readlines()
	newLines = []
	aiid = 0
    
	for line in lines:

		newLine = line
		index = line.find('/>')

		if index != -1:

			aiid = aiid + 1
			newLine = line.replace('/>', ' id="'+str(aiid)+'" />')
			
		newLines.append(newLine)

	# Write the file back
	for line in newLines:
  		thefile.write(line)
