It think he's saying it should look like this:

# File: masseditor.py

import re

import time

p1= re.compile('(href=|HREF=)+(.*)(#)+(.*)(\w\'\?-<:)+(.*)(">)+')
p2= re.compile('(name=")+(.*)(\w\'\?-<:)+(.*)(">)+')
p100= re.compile('(a name=)+(.*)(-)+(.*)(></a>)+')

def massreplace():
editfile = open("C:\Program Files\Credit Risk Management\Masseditor
\editfile.txt")
filestring = editfile.read()
filelist = filestring.splitlines()

for i in range(len(filelist)):
source = open(filelist[i])
starttext = source.read()

for i in range (13):
interimtext = p1.sub(q1, starttext)
interimtext= p2.sub(q2, interimtext)
interimtext= p100.sub(q2, interimtext)
source.close()
source = open(filelist[i],"w")
source.write(finaltext)
source.close()

massreplace()

I'll try that and see how it works...

Ok, if you want a single RE... How about:


test = '''
<a href="Web_Sites.htm#A Web Sites">
<a name="A Web Sites"></a>
<a
href="Web_Sites.htm#A Web Sites">
<a
name="A Web Sites"></a>
<a HREF="Web_Sites.htm#A Web Sites">
<a name=Quoteless></a>
<a name = "oo ps"></a>
'''

import re

r = re.compile(r'''
(?:href=['"][^#]+[#]([^"']+)["'])
| (?:name=['"]?([^'">]+))
''', re.IGNORECASE | re.MULTILINE | re.DOTALL | re.VERBOSE)

def zap_space(m):
return m.group(0).replace(' ', '_')

print r.sub(zap_space, test)

It prints out

<a href="Web_Sites.htm#A_Web_Sites">
<a name="A_Web_Sites"></a>
<a
href="Web_Sites.htm#A_Web_Sites">
<a
name="A_Web_Sites"></a>
<a HREF="Web_Sites.htm#A_Web_____________________________Sites">
<a name=Quoteless></a>
<a name = "oo ps"></a>
