Regular expression for numeric values

Hi:
Due to limitations within our environment, I have to use text fields to enter in numeric data only. The client would need to be prompted upon entering a letter that this field excepts only numeric characters.
I am using the code below on the change event for the field and it works fine except that the client can not enter decimals or commas. Does anyone know how to escape the period and commas with this expression?
if (xfa.event.change.match(/[0-9\-]/) == null)
xfa.event.change = "";
xfa.host.messageBox("Only numbers are permitted for this field.");

Hi,
This script in the change event will give the warning. I am just thinking if script could also delete the offending character:
var vPattern = /[a-z]/;
var result = vPattern.test(xfa.event.newText);
if (result == true)
xfa.host.messageBox("Only numbers are permitted for this field.");
Good luck,
Niall

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$

Request some help, over procedure's performance uses regular expressions for its functinality

Hi All,
        Below is the procedure, having functionalities of populating two tables. For first table, its a simple insertion process but for second table, we need to break the soruce record as per business requirement and then insert into the table. [Have used regular expressions for that]
        Procedure works fine but it takes around 23 mins for processing 1mm of rows.
        Since this procedure would be used, parallely by different ETL processes, so append hint is not recommended.
        Is there any ways to improve its performance, or any suggestion if my approach is not optimized? Thanks for all help in advance.

Regex's are known to be CPU intensive specially when dealing with large number of rows.
If you have to reduce the processing time, you need to tune the Select statements.
One suggested change could be to change the following query
SELECT
             REGEXP_SUBSTR(P_EXCEPTION_RECORD, '([^^])+', 1,t2.COLUMN_VALUE) str
        FROM
            DUAL t1 CROSS JOIN
                    TABLE
                        CAST
                            MULTISET
                                SELECT LEVEL
                                FROM DUAL
                                CONNECT BY LEVEL <= REGEXP_COUNT(P_EXCEPTION_RECORD, '([^^])+')
                            AS SYS.odciNumberList
                    ) t2
to
SELECT REGEXP_SUBSTR(P_EXCEPTION_RECORD, '([^^])+', 1,level) str
FROM DUAL
CONNECT BY LEVEL <= REGEXP_COUNT(P_EXCEPTION_RECORD, '([^^])+')
Before looking for any performance benefit, you need to ensure that this does not change your output.
How many substrings are you expecting in the P_EXCEPTION_RECORD? If less than 5, it will be better to opt for SUBSTR and INSTR combination as it might work well with the number of records you are working with. Only trouble is, you will have to write different SUBSTR and INSTR statements for each column to be fetched.
How are you calling this procedure? Is it not possible to work with Collections? Delimited strings are not a very good option as it requires splitting of the data every time you need to refer to.

Using regular expressions for validation in i18n

Can we use regular expressions for validation of inputs in a java application taking care of i18N aspects too. Zip code for different locales are different. Can we use regular expressions to validate zipcode inputs from different locales

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

^[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"

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).

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 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}
