RE: Can Regex find and replace the 7th and 8th character of a line.
Rodney,
You're regex is accurate. You just need to use it in this format.
result = mystring.ReplaceAll((?m)^(.{6})08, $142);
I assume REReplace is getting confused on the numerics.

So the 7th and 8th characters are 0 and 8, and you want to replace that
with
4 and 2?
REReplace(mystring, (?m)^(.{6})08,\1 42,ALL)
This is the closest I can get except I can't get CF to treat \142 as
backreference 1 42. A workaround would to call ReReplace twice:
result = REReplace(mystring, (?m)^(.{6})08,\1xBUGx,ALL);
result = REReplace(result, (?m)xBUGx,42,ALL);
Maybe some regex god can find a better solution without having to make
the
duplicate REReplace() call.

However you do it, I'd look at a Java StringBuilder or StringBuffer, because
any string manipulation with CF over that many lines is going to blow up
with a Java out of memory exception since every concatenation or string
function call creates another string in memory.

I would rather write a CFX tag in C.

Re: Can Regex find and replace the 7th and 8th character of a line.
OK, I stand corrected. For anyone who doesn't want to waste time writing C-based CFX tags just to duplicate something that is built into the Java API, I'd recommend a Java StringBuffer or StringBuilder.

Hello Regex help again :o) I'm doing a cfhttp to a page, and want to take out the following string from the cfhttp.filecontent variable. input type=hidden name=robotfile value=n_nn Where n is a number...

Re: Regex find
You could have a look at CF_REextract at http://www.contentbox.com/claude/customtags/REextract/testREextract.cfm?p=hf It has been designed especially for this kind of job and can even get the page by HTTP for you. In your particular case, you could just use: CF_REextract INPUTMODE = http INPUT = Your http address RE1 = 'robotfile[[:space:]]+' RE2 = '' OUTPUTMODE = list OUTPUT = your variable name and get the content in your variable. You could also get all occurences if you want in a query, and have it more general depending on the reg expressions you give. ~| Archives: http://www.houseoffusion.com/lists.cfm?link=t:4 Subscription: http://www.houseoffusion.com/lists.cfm?link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Your ad could be here.

regex find form vars in queries?
I'm missing something here - it seems like it should be straight-forward. I need to find all form (and url) scoped variables in cfqueries. I'm having problems getting the regex to stop at the first /cfquery - it goes to the last one on the page.

Re: regex find form vars in queries?
Sure. As they say, Perl is greedy. (as is RegEx.) It grabs the biggest string that matches the criteria. If you don't want it to, but instead grab the smallest. you must qualify the search, using the ? character. So if you have a * or a ?, replace it with a *? or a ??.

RE: regex find form vars in queries?
That solution will only work in Perl. The CF regex engine cannot handle non-greedy matching. If you do more than a little work with regexes you may want to consider downloading my (completely free) PCRegEx CFX tag, which gives CF Server Perl-Compatible regexes, including non-greedy matching. URLs are at the bottom of this message. As far as a one-line regex for pasting into CFStudio, try this: CFQUERY[^]*(([^#]|[^/])*#(Form|URL)\.[^#]+#)+([^#]|[^/])*/CFQUERY It worked on the following test cases: CFQUERY DATASOURCE=foodelete from foo where bar = #Form.baz#/CFQUERY CFQUERY DATASOURCE=foodelete from foo where bar = #Form.baz# and quux = 1/CFQUERY CFQUERY DATASOURCE=foodelete from foo where bar #URL.fark#/CFQUERY CFQUERY DATASOURCE=foodelete from foo where quux = 1/CFQUERY CFQUERY DATASOURCE=foo#Form.Query#/CFQUERY That is, it correctly matched all but line 4. Unfortunately, it will *not* correctly match the following case: CFQUERY DATASOURCE=foo#PreserveSingleQuotes(Form.Query)#/CFQUERY That is, a case where there is a Form/URL variable, but it is not referenced directly with octothorpes. Those are *much* harder to find correctly. You can try this: CFQUERY[^]*([^UF]|F[^o]?[^r]?[^m]?[^.]?|U[^R]?[^L]?[^.]?|[^/])+(Form\.| URL\.)([^]|[^/])+/CFQUERY But it runs *very* slowly. It took a few seconds just to find the 5 that match from this email! If you can say with confidence that you don't have function-wrapped Form/URL variables, you should definitely use the first case. Actually, your best bet would be a programmatic one in this case, I think. Much safer.
