• Generating a list of values a regex COULD match in Python

  - by mlissner

  I'm trying to use a regex as an input, and from there generate all the possible values that the regex would match. So, for example, if the regex is "three-letter words starting with a, and ending in c," then the code would generate a list with the values [aac, abc, acc, adc, a1c....]. Is there an easy way to do this? I'm using python.

• Fuzzy match two hash tables?

  - by alex

  Hi, I'm looking for ideas on how to best match two hash tables containing string key/value pairs. Here's the actual problem I'm facing: I have structured data coming in which is imported into the database. I need to UPDATE records which are already in the DB, however, it's possible that ANY value in the source can change, therefore I don't have a reliable ID. I'm thinking of fuzzy matching two rows, source and DB and make an "educated" guess if it should be updated and inserted. Any ideas would be greatly appreciated.

• Fuzzy match in sharepoint search engine?

  - by SeeBees

  In sharepoint 2007 sites, we can search for people or other contents. Is the search engine able to do fuzzy match so that "Micheal" can be corrected to "Michael"? If it's possible, does it need extra configuration? I am also writing a custom webpart that uses sharepoint search service, a web service that has url like "http://site/_vti_bin/search.asm". Is it possible to use this service to do fuzzy search as well? Thanks.

• Exact match in regex character sets

  - by Dominik

  Hi all Consider the following string '35=_-235-b-35=35-35=2-135=a-35=123-235=2-35=a-53=1-53=a-553=b' I'd like to extract everything that matches 35= followed by 1 or 2 characters. What I came up with is the following regex \d[35]=[A-Za-z0-9]{1,2} The problem is the character set [35] matches both 35= and 53=. How can I achieve an exact match for a character set? Any suggestions, or different approaches are very much appreciated!

• Using a regex to match IP addresses in Python

  - by MHibbin

  I'm trying to make a test for checking whether a sys.argv input matches the regex for an IP address... As a simple test, I have the following... import re pat = re.compile("\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3}") test = pat.match(hostIP) if test: print "Acceptable ip address" else: print "Unacceptable ip address" However when I pass random values into it, it returns "Acceptable ip address" in most cases, except when I have an "address" that is basically equivalent to \d+ Any thoughts welcome. Cheers Matt
