I'm stuck on a problem where I need to make a filter to find a DN that doesn't have a "DC=blah" string.
so I have:
(!(distinguishedName='*DC=blah*'))
But that is not getting through well.
Help please!
EDIT: Sorry I forgot to put asterisk in the search string.
An excellent question. The negation filter you seek is (!(distinguishedName=dc=blah*)). A backslash cannot be used in an assertion unless it is followed by two hexadecimal characters. The quotes are not necessary unless they are part of the assertion.
This will work if distinguishedName is an attribute. Otherwise, DN components must be used in an extensible match filter. For more information, see "LDAP: ldapsearch", "LDAP: Mastering search filters", and "LDAP: Programming Practices".
I can't test it here, but maybe try this
(!(distinguishedName='DC\=blah'))
It seemed like there was NO WAY to get the DN filtered to way I like it so I had to use second filtering method using CFQUERY.
<cfquery dbtype="query" name="secondFilter">
SELECT * FROM firstFilter WHERE dn NOT LIKE '%DC=blah%'
</cfquery>

I am trying to build a regex in Excel;s data validation. However, it is not working.
Would you please explain how could I put data validation in Excel
I want last name data validation with characters, quote('), space and dot.
=ISNUMBER(MATCH("^[a-zA-Z\s,.']*$",F:F,0))
I am using above formula and, again, it is not working
For SSN, I am using following formula and it is not working
=AND(ISNUMBER(MATCH("/^\d{3}-\d{2}-\d{4}$/",A2,0)),LEFT(A2,1)>=0)
Please help me to build data validation from data tab or VBA script for the data validation.
The MATCH function in Excel is not used for regex matching.
But you do not need it here, it looks like.
To allow only letters and ,.' you could use formula like this:
=ISNUMBER(SUMPRODUCT(SEARCH(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1)," ,.'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ")))
To validate an SSN try the formula from the guide here
=AND(LEFT(F1,1)>="0",LEN(F1)<10,ISNUMBER(F1))
Some more pointers:
More Data Validation examples
Adding validation to a cell using VBA is described here and using Regex in VBA here, as noted.
Unfortunately, the Match Function is not able to support regex. It can only match a single, constant value.
I suggest you take a look at This very detailed post, which explains beautifully how to use Regular Expressions in Excel.
Other than that, your Regular Expression looks to be in working order - if you get this set up, it should work immediately. Good luck!
I'm relatively new to regex and in order to set up a goal in Google Analytics, I'd like to use a regular expression to match a URL containing both "thank-you" and "purchaseisFree=False" but exclude two specific rate plans that are represented in the URL as "productRatePlanID=5197e" and "productRatePlanID=c1760".
Here is a full URL example:
https://www.examplepage.com/thank-you?productRatePlanId=5197e&purchaseIsFree=False&grossTotal=99.95&netTotal=99.95&couponCode=&invoiceNumber=INV00000589
I tried using this post as a model and created this regex:
\bthank-you\b.+\purchaseIsFree=False\b(?:$|=[^c1760]|[^5197e])
However, I'm not getting the desired results. Thanks in advance for any suggestions.
I think the below mentioned regex should solve your problem. It uses the positive|negative look ahead facility. We can sit at the beginning of http[s] and check all the three condition and then engulp the whole tree
(https?:\/\/)(?=.*?productRatePlanId=(?!5197e&)(?!c1760&))(?=.*?thank-you)(?=.*?purchaseisFree=False).*
Note:- I have used & after the productRatePlanId values just to ensure it doesnt ignore other values as 5197f, 5198d and all other sorts of values.
I don't really know regex, but would like a quick solution to search and replace links. I want to use the search regex wordpress plugin to remove links in my post. How do I format the regex to a link like this:
http://website.com/index.php?id=934&title=item name
edit: the numbers in the id and the item name varies
Thank you in advance!
Try this one out: http://regexr.com?2vjq6
Depending on whether or not you need whitespace in your "title" parameter, the regex I provided may need to be altered. Best practice would be to not have whitespace in your URLs (use URL encoding instead, where a space = %20).
http://website.com/index.php\?id=[0-9]*&title=[a-zA-Z0-9\-]*
Try this pattern
(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,#?^=%&:/~\+#]*[\w\-\#?^=%&/~\+#])?
I am using this regex :
[']?[%]?[^"]#([^#]*)#[%]?[']?
on this text:
insert into table (id,name,age) values ('#var1#' ,#var2#,'#var3#', 3, 'name') where id = '#id#' like ""
and test=<cfqueryparam value="#id#">
For some reason it is catching the comma between #var2# and '#var3#'
but when I include a [^,] it starts doing weird stuff.
Can someone help me with this one.
As I read my regex now, it should find anything that:
might have a single quote
might have a percentage
doesn't have a double quote
then has a hash (#)
followed by no hash, but all other characters
then has a hash and followed by a percentage or quote
So why, when I add "no comma" in front does the regex break??
Updated Question:
okay, Ill try to explain: a query can look like this:
SELECT e.*, m.man_id, m.man_title, c.cat_id, c.cat_name
FROM ec_products e, ec_categories c, ec_manufacturers m
WHERE c.cat_id = e.prod_category AND
e.prod_manufacturer = m.man_id AND
e.prod_title LIKE <cfqueryparam value="%#attributes.keyword#%"> and
test='#var1#'
ORDER BY e.prod_title
Now I want every value between ##, but not the values that are surrounded by a queryparam tag. So in the example I do want #var1# but not #attributes.keyword#. Reason for this is that all params in the query that are not surrounded by a tag are unsafe and can cause SQL injection. My current regex is
(?!")'?%?#(?!\d)[\w.\(\)]+#%?'?(?!")
and it is almost there. It does find the attributes.keyword because of the %. I just want anything that that has ## but not surrounded by double quotes, so not "##". This will give me all unsafe params in the sql, like '#var#', or #aNumber#, or '%##', or '%##%', or '##%, but NOT things like
<cfqueryparam value="#variable#">
. I hope you understand my intentions?
I think you might be misunderstanding [^"]. It doesn't mean "doesn't have a double quote", but rather means, "one character, which is not a double-quote". Similarly, [^,] means "one character, which is not a comma". So your regex:
[']?[%]?[^"]#([^#]*)#[%]?[']?
will match — for example — this:
2#,'#
which consists of zero single-quotes, zero percent-signs, one character-which-is-not-a-double-quote (namely 2), one hash-sign, two characters-which-are-not-hash-signs (namely ,'), one hash-sign, zero percent-signs, and zero apostrophes. The ,' is what will be captured by the parentheses.
Update for updated question:
I don't think that what you describe is possible using just a ColdFusion regex, because it would require "lookbehind" (to ensure that something is not preceded by a double-quote), which ColdFusion regexes apparently (according to a Google-search) do not support. However:
This StackOverflow answer gives a way of using Java regexes in ColdFusion. If you use that technique, then you can use the Java regex '?%?(?<!")(?<!"')(?<!"%)(?<!"'%)#(?!\d)[\w.()]+#(?!%?'?")%?'? to ensure that there's no preceding double-quote.
You never mentioned how you're actually using this regex. Would it work for you to match .'?%?#(?!\d)[\w.()]+#%?'?(?!") (i.e., to match not just the section of interest, but also the preceding character), and then separately confirm that the matched substring doesn't start with a double-quote?
I also feel compelled to mention, since it sounds like you're trying to use regex-based pattern-matching to help detect and address points of possible SQL injection, that this is a bad idea; you will never be able to do this perfectly, so if anything, I think it will end up increasing your risk of SQL injection (by increasing your reliance on a buggy methodology).
Preserving your capture group from the initial regex, here is a revised expression.
'?%?(?!")#([^#]+)#%?'?
Based on the information you provided this should be correct.
'?%?(?!")#[^#]+#%?'?
I need to enhance the search functionality on a page listing user accounts. Rather than have multiple search boxes for each possible field, or a drop down menu where the user can only search against one field, I'd like a single search box and to use a gmail like syntax. That's the best way I can describe it, and what I mean by a gmail like search syntax is being able to type the following into the input box:
username:bbaggins type:admin "made up plc"
When the form is submitted, the search string should be split into it's separate parts, which will allow me to construct a SQL query. So for example, type:admin would form part of the WHERE clause so that it would find any record where the field type is equal to admin and the same for username. The text in quotes may be a free text search, but I'm not sure on that yet.
I'm thinking that a regular expression or two would be the best way to do this, but that's something I'm really not good at. Can anyone help to construct a regular expression which could be used for this purpose? I've searched around for some pointers but either I don't know what to search for or it's not out there as I couldn't find anything obvious. Maybe if I understood regular expressions better it would be easier :-)
Cheers,
Adam
No, you would not use regular expressions for this. Just split the string on spaces in whatever language you're using.
You don't necessarily have to use a regex. Regexes are powerful, but in many cases also slow. Regex also does not handle nested parameters very well. It would be easier for you to write a script that uses string manipulation to split the string and extract the keywords and the field names.
If you want to experiment with Regex, try the online REGex tester. Find a tutorial and play around, it's fun, and you should quickly be able to produce useful regexes that find any words before or after a : character, or any sentences between " quotation marks.
thanks for the answers...I did start doing it without regex and just wondered if a regex would be simpler. Sounds like it wouldn't though, so I'll go back to the way I was doing it and test it again.
Good old Mr Bilbo is my go to guy for any naming needs :-)
Cheers,
Adam
