What is regular expression for cheking a set operation

I want a regular expression for checking the syntax of the set operation given as input
ex:
the input should be
[1,2,3]+[2,3] or [1,2]-[2] or [1,2,3]*[1,2]
is should check the square bracket and the operator between two set operands

I think you should code that from scratch. When you validate input, you usually want to tell the user what they did wrong, but a regex will only tell you whether it matches or not.

What is the regular expression for the end of a story?

Forgive me if this is wrong forum for asking this, but I'm trying to use the Find command using GREP and I need to know the regular expression for the end of a story. (Or, the last character of a story.) Thanks in advance.

I'd try search for .\z (that's a dot in front) which ought to find the very last character in the story, and replace with $0 and your additional text.
You know you can use a keyboard shortcut to move your cursor to the end of any story, right? Ctrl + End on Windows, Cmd + End, I think, on Mac. Unless you want to do this to every single story in the document, I would think you might be just as well off to put your text on the clipboard, put the cursor in the story and hit the key combo followed by Ctrl/Cmd + V to paste.

Wat should be the regular expression for string MT940_UB_*.txt to be used in SFTP sender channel in PI 7.31 ??

Hi All,
What should be the regular expression for string MT940_UB_*.txt and MT940_MB_*.txt to be used as filename inSFTP sender channel in PI 7.31 ??
If any one has any idea on this please let me know.
Thanks
Neha

Hi All,
None of the file names suggested is working.
I have tried using - MT940_MB_*\.txt , MT940_MB_*.*txt , MT940*.txt
None of them is able to pick this filename - MT940_MB_20142204060823_1.txt
Currently I am using generic regular expression which picks all .txt files. - ([^\s]+(\.(txt))$)
Let me know ur suggestion on this.
Thanks

The post-expression for the step 'Set Station Global Models' could not be evaluated.

When running a TestStand sequence, I get the following error message:
The post-expression for the step 'Set Station Global Models' could not be evaluated.
Variable or property types do not match or are not compatible.
Error Code: -17321; Variable or property types do not match or are not compatible.
Although I do understand what the above is telling me, fixing the root cause is somewhat another thing.
I'll explain the scenario. The code is developped in TS4.1.0, although that should be irrelevant.
I inherited a TestStand project which calls LabVIEW modules. The original sequence works fine on the test pc (which is remotely located). The local and remote PC's share the same StationGlobals.ini.
Here is why it is strange.. I do get the error message on the local PC whether I use the old or the new code. I was assuming that using the same StationGlobals.ini would have fixed that, but it didn't.
When I run the old code on the remote PC, I do not get that message, but I do get it with the new code. I don't recall modifying code that affected the StationGlobals. My goal is to fix it on both machines (at least the remote one).
This is the expression that it does not like:
StationGlobals.Models=Locals.Models,
However, that very same expression exists in the original code. The one thing that did change is the addition of a new model number in the Locals.Models.newNumber. I suspect that this contributes to the error. But why does it give me an error when I run the original sequence locally? Maybe I should try running it again..
In either case, any suggestions to overcome the error?
Thanks.

Solved!
Go to Solution.

Please ignore post.
I found the problem.. There was a mismatch with the number of models. Easy fix. It's all good.
For someone else who might tumble onto this thread for the same reason, here's an explanation.
I added a new model with its variants to the list of Locals.Models. In total, there were 16 additions to the list.
I also added these to the StationGlobals. Which meant that my StationGlobals no longer matched the one on the remote PC.
Where the error came in is that there was one missing model in the StationGlobals, so the size (number of models) did not match that of the Locals.
Slight oversight in the sea of models that are listed (I'm not even going to count them). Now fixed.
... and embarrassed ...
I may as well give myself an "Accepted Solution".

Regular Expression for a Person's Name

Hi,
I am using the org.apache.regexp package and trying to find the regular expression for a person's name. It allows only the alphabetic string.
I tried [a-zA-Z]+. But this also accepts the thing like "BUSH88", which is not what I want...
Can anybody help me figure this out?
Thanks in advance,
Tong

Thanks in advance,

^[a-zA-Z]+$
the ^ represents the start of the String and the $ represents the end.
So the expression is saying: "between the beginning and the end of the String there will only be alphbetical characters"

Regular expression for DBCC

Hi Everyone,
I need help with regular expression for following scenario .
If any of the DBCC command is run against sql server i want it to be captured . Something like if it starts with DBCC it should be captured .
For instance following is expression for
DBCC CheckDB : part="dbcc checkdb", rgxp="(\s|;|^)dbcc\scheckdb\s?$(((to[a-z0-9_\$\#\.\@])|(t[abcdefghijklmnpqrstuvwxyz0-9_\$\#\.\@])|([abcdefghijklmnopqrsuvwxyz]))[a-z0-9_\$\#\.\@]*)\s?$(\s|;|$)"
But instead of writing expression for all DBCC commands is there any way to write a regular expression say if DBCC i want it to be captured .
Thanks
Suhas Vallala

Hi Suhas,
As Olaf said, regular expressions is not supported in SQL Server. To trace the DBCC event, you can use the SQL Sever Profiler, just tick the Security Audit--> Audit DBCC Event. You can set up a trace in the profiler by following the below tutorial.
SQL SERVER – Introduction to SQL Server 2008 Profiler
If you have any question, feel free to let me know.

How to write the regular expression for Square brackets?

Hi,
I want regular expression for the [] Square brackets.
I have tried to insert in the below code but the expression not validate the [] square brackets.
If anyone knows please help me how to write the regular expression for [] Square brackets.
private static final Pattern DESC_PATTERN = Pattern.compile("({1}[a-zA-Z])" +"([a-zA-Z0-9\\s.,_():}{/&#-]+)$");Thanks
Raghav

Since square brackets are meta characters in regex they need to be escaped when they need to be used as regular characters so prefix them with \\ (the escape character).

Regular Expression For Dreamweaver

I still haven't had the time to really become a professional when it comes to regular expressions, and sadly I am in need of one an finding it difficult to wrap my head around.
In a text file I have hundreds of instances like the following:
{Click here to visit my website}{http://www.adobe.com/}
I need a regular expression for Dreamweaver that I can run within the "Find and Replace" window to switch the order of the above elements to:
{http://www.adobe.com/}{Click here to visit my website}
Can anyone provide some guidance? I'm coming up short due to my lack of experience with regular expressions.
Thank you in advance!

So you have a string that starts { and goes until the first }. Then you have another string exactly the same. And you want to swap them. I'm not making any assumption that the second one has to look like a URL (that's a whole other minefield, but perhaps you could do something simple like it must start with http).
You don't specify how your text file is divided up, have you got this as a complete line to itself, or is it just a huge block of text? Preferably as individual lines.
I don't have Dreamweaver, but this worked for me in Notepad++
Find: ^{(.*?)}{(.*?)}$
Replace with: {\2}{\1}
My file looked like this:
{Click here to visit my website}{http://www.adobe.com/}
{some other site}{http://www.example.com/foo}
And doing a Replace All ended up like this:
{http://www.adobe.com/}{Click here to visit my website}
{http://www.example.com/foo}{some other site}

Regular expression for LOV?

I have a list of strings in an LOV. I tried filtering it by typing in "^disk" in the search bar, which I hope will return a list of strings starting with "disk", but I failed.
Any idea on how to use regular expression for LOVs? Thanks!

HI Buffalo,
i have a select list item in my page1 named :P1_EMPNAME with lov query value
select ename as d, ename as r from emp WHERE EGEXP_LIKE(ename,:P1_SEARCH) or :P1_SEARCH IS NULL
i have a Search text box in my page1 name :P1_SEARCH
When i run the page, by default all the empnames will display in the lov list item
i have given ^buffalo in the text seach item and clicked the submit button ,it shows the Employee buffalo in my list item lov.
If you want all the entries that start with S, search for ^s
End with R, use r$
please try this link http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28424/adfns_regexp.htm

Regular Expression for PathName???

Anyone have a "ready to go" regular expression for detecting a pathname?
for example I need to detect the following:
myfile.txt
./myfile.txt
../my-file.ini
/home/my-home/myFile.foo
etc.
Now, in a perfect world, it could also do Windows (or ANY OS for that matter) pathnames (though this is not terrbibly important for my case at least).
TIA,

I will leave it to you as an excercise to add support for spaces in path names, different separator characters, etc..
