Regular expression for period plus double line
Hi guys,
i am new to Regular Expressions. How do I construct one to find a period followed by two end of lines.
Also is there a good GUI utility for building regular expressions.
thanks
http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html
use
boolean b = Pattern.matches(Regex, Your String);
where
Regex = ".*\\.--.*"
. = anything
* = 0 or more times
You need .* before and after so it will find the pattern inside of
whatever other stuff exists in the string.
You have to escape the period with \\.
(otherwise the . means 'anything' as stated before)
import java.util.regex.Pattern;
public class RegEx{
public static void main(String[] args) {
String Line = "k1*&.--jh3";
String RegEx = ".*\\.--.*";
boolean found = Pattern.matches(RegEx, Line);
System.out.println("Found? - " + found);
}

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 recognizing all tables in a sql statement
Hi all
I need a regular expression for recognizing all the tables bane in a geberic statement.
Unlikely i need a regular expression that manage also inner join .I 'm sorry but this matter is new for me and i cannot find any usefull help in the web.
RegardsIf you insist it should be something like:
"SELECT ([A-Z0-9_]+)[.][A-Z0-9_]+(,([A-Z0-9_]+)[.][A-Z0-9_]+)* FROM (([A-Z0-9_]+)[.][A-Z0-9_]+) INNER JOIN (([A-Z0-9_]+)[.][A-Z0-9_]+) ON .+" plus spaces etc... Yes it's for this kind of statements only.
But SQL parser is better because anyway you'll need to at least remove duplicates from founded names... -
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

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

Let me know ur suggestion on this.

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,

^[a-zA-Z]+$

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
RaghavSince 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).

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 $0 and your additional text.
You know you can use a keyboard shortcut to move your cursor to the end of any story, right? Ctrl + End on Windows, Cmd + End, I think, on Mac. Unless you want to do this to every single story in the document, I would think you might be just as well off to put your text on the clipboard, put the cursor in the story and hit the key combo followed by Ctrl/Cmd + V to paste. -
Regular expression for LOV?
I have a list of strings in an LOV. I tried filtering it by typing in "^disk" in the search bar, which I hope will return a list of strings starting with "disk", but I failed.
Any idea on how to use regular expression for LOVs? Thanks!HI Buffalo,
i have a select list item in my page1 named :P1_EMPNAME with lov query value
select ename as d, ename as r from emp WHERE EGEXP_LIKE(ename,:P1_SEARCH) or :P1_SEARCH IS NULL
i have a Search text box in my page1 name :P1_SEARCH
When i run the page, by default all the empnames will display in the lov list item
i have given ^buffalo in the text seach item and clicked the submit button ,it shows the Employee buffalo in my list item lov.
If you want all the entries that start with S, search for ^s
End with R, use r$
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,
