Description of problem:
Step 1: download the text from http://rest.kegg.jp/get/cpd:C00132
Step 2: perform a re.match('^\w+', line) with line equal to "DBLINKS     CAS: 67-56-1\n" (that's line 23, by my count)
Step 3: wat

Running the following python code will cause an error:

import urllib2
import time
import re

def get_test(db,iD):
	t1 = float(time.clock())
	a = urllib2.urlopen('http://rest.kegg.jp/get/' + db + ':' + iD)
	#a = urllib2.urlopen('http://rest.kegg.jp/list/cpd')
	
	rawString = a.read().decode('utf-8')
	t2 = float(time.clock())
	r = float(t2-t1)
	print r

	return rawString
	
def parse_response(response):
	
	currentField = None
	data = {}
	
	for line in response.split('\n'):
		newField = re.match('^\w+', line)
		print line
		print newField
		if newField:
			currentField = newField.group(0)
			lineData = re.findall('\s\S+', line)[1:]
			lineData.append('\n')
			lineData = "".join(map(str, lineData))
			data[currentField] = lineData
			print "here"
		else:
			#print currentField
			lineData = str(line)
			data[currentField] = data[currentField].join(lineData)
			
	return data	

The data from the restful interface is:
