Using regular expressions for validating time fields

Similar to my problem with converting a big chunk of validation into smaller chunks of functions I am trying to use Regular Expressions to handle the validation of many, many time fields in a flexible working time sheet.
I have a set of FormCalc scripts to calculate the various values for days, hours and the gain/loss of hours over a four week period. For these scripts to work the time format must be in HH:MM.
Accessibility guidelines nix any use of message box pop ups so I wanted to get around this by having a hidden/visible field with warning text but can't get it to work.
So far I have:
var r = new RegExp(); // Create a new Regular Expression Object
r.compile ("^[00-99]:\\] + [00-59]");
var result = r.test(this.rawValue);
if (result == true){
true;
form1.flow.page.parent.part2.part2body.errorMessage.presence = "visible";
else (result == false){
false;
form1.flow.page.parent.part2.part2body.errorMessage.presence = "hidden";
Any help would be appreciated!

Date and time fields are tricky because you have to consider the formattedValue versus the rawValue. If I am going to use regular expressions to do validation I find it easier to make them text fields and ignore the time patterns (formattedValue). Something like this works (as far as my very brief testing goes) for 24 hour time where time format is HH:MM.
// form1.page1.subform1.time_::exit - (JavaScript, client)
var error = false;
form1.page1.subform1.errorMsg.rawValue = "";
if (!(this.isNull)) {
var time_ = this.rawValue;
if (time_.length != 5) {
    error = true;
else {
    var regExp = /^([01]?[0-9]|2[0-3]):[0-5][0-9]$/;
    if (!(regExp.test(time_))) {
      error = true;
if (error == true) {
form1.page1.subform1.errorMsg.rawValue = "The time must be in the format HH:MM where HH is 00-23 and MM is 00-59.";
form1.page1.subform1.errorMsg.presence = "visible";

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

hi,
For that shall i have to create individual patterns for matching the inputs from different locales or a single pattern will do in the case of validating phone nos. around the world, zip codes etc. In case different patterns are required, programmer should have a konwledge of difference in patters for different locales.

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 Completion

I'm trying to build a text completer for a simple little editor. The general idea is that I have a regular expression which describes the syntax of an expression and a set of strings which are all semantically valid cases of the expression (the latter of which is not particularly important to my problem). I would like to be able to determine, using the expression described, whether or not a section of text is capable of beginning a syntactically valid expression, not matching it.
For example, given the expression
"#[A-Za-z0-9]#" the string "#name#" is syntactically valid, whereas the string "#_blarg" is not. What I would like to do is be able to determine that "#partial" has the potential to match the pattern with more input, even if it doesn't yet. Specifically, the eventual use will be in such a case as the string X=#partial+3. If the cursor is positioned before the "+" and my user presses the completion keystroke, I want to recognize that "#partial" is what I need to recognize. Also, positioning the cursor immediately after the "=" and pressing the keystroke will do nothing, since nothing before the "=" is capable of matching the pattern properly.
Is this possible? I don't have to use this exact approach, but it is important that I be able to use the regular expression in detecting a partially completed expression. If I can, the set of regular expressions which already exist in the code can be used to drive the auto completer. Otherwise, I'll have to write a special recognition module for each case; that wouldn't be pretty.
Thanks for your time! I'll provide other information upon request, if it'd help. :)

Thank you both for discussing this; it has definitely helped me in reaching a better understanding of uncle_alice's answer to my problem. I've adjusted my code to use this approach and, for the most part, it seems to work.
I say "for the most part" because I am compiling Patterns with the case insensitivity flag. This appears to do horrible, horrible things. Take a look at the following code, modified from uncle_alice's example:
String[] str = {"#test#hello", "#tes", "blargblarg", "", "#test#", "S"};
String rgx = "#[A-Za-z0-9]+#";
Pattern pc = Pattern.compile(rgx);
Pattern pi = Pattern.compile(rgx, Pattern.CASE_INSENSITIVE);
for (String s : str)
    System.out.println("    For string: "+s);
    for (Pattern p : new Pattern[]{pc, pi}) // once for each pattern
        Matcher m = p.matcher(s);
        if (m.matches())
            System.out.printf("Matched '%s'", m.group());
        } else
            System.out.print("No match");
        System.out.println("; hitEnd = " + m.hitEnd());
}That produces the following output:
    For string: #test#hello
No match; hitEnd = false
No match; hitEnd = true
    For string: #tes
No match; hitEnd = true
No match; hitEnd = true
    For string: blargblarg
No match; hitEnd = false
No match; hitEnd = true
    For string:
No match; hitEnd = true
No match; hitEnd = true
    For string: #test#
Matched '#test#'; hitEnd = false
Matched '#test#'; hitEnd = false
    For string: S
No match; hitEnd = false
No match; hitEnd = trueIt would seem that, with the case-insensitive flag set, hitEnd always returns true unless a match is found. Why is this? I find it quite confusing.
I can adjust my design to accomodate if this problem cannot be circumvented; however, I'd like to understand what has going wrong here. :)
Cheers! Thanks so much for all your help!

Need a Better Regular Expression for Validating Dates

I have data coming from file with date in the format DD-MON-YY.
I have created the following regular expression:
'^([0-2]{1}[0-9]{1}|[3]{1}[0-1]{1})-(JAN|FEB|MAR|A PR|MAY|JUN|JUL|AUG|SEP|OCT|NOV|DEC|Jan|Feb|Mar|Apr |May|Jun|Jul|Aug|Sep|Oct|Nov|Dec)-[[:digit:]]{2}$'
However, it doesn't catch dates like 31-APR, 29-FEB. Can someone make changes to it to make it foolproof

How to use Regular expression

Hi,
I have a file that contains this format (separated by ;(semicolon) ):
user id;user name;email address;password;integer;list of integer(separated by ,(comma))
below is the example data :
abc;Abc;[email protected];password1;1;1,2
def;Def;[email protected];password;2;1,2,3
ghi;Ghi;[email protected];password;2;1
my question is how to verify the valid input for each row using regular expression..? TQ

@Op. Doing a correct validation of e-mailaddresses
is very hard using regular expressions (doingbasic
validation is however easy)
http://www.regular-expressions.info/email.html
I like the RFC 822 compliant regexp :)

Regular Expression to validation email address

I want to validate an Email address and I need a regular expression for validating the email address.
Email address requirement:
1) It should not start with numbers, say like [email protected]
2) It should be limited to 65 characters long including domain name.
3) It should not have numeric domain names like [email protected]
ANy inputs will be great.
Thanks

Oh ok. If domain names can begin with numbers and its valid, then I'do like to incorporate it. Thanks for the info.
In that case let me rephrase my requirement:
Email address requirement:
1) It should not start with numbers, say like [email protected]
2) It should be limited to 65 characters long including domain name.So, you just arbitrarily refuse to deal with entire classes of email addresses? Why?

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$

Help with Regular Expression for field validation

I'm fairly new to using regular expressions and using Acrobat. This is probably a simple question, but I've been unable to figure it out.
I have a text field on a PDF that I would like to be 9 characters in length. The first 2 characters can only be alphanumeric, the last 7 characters can only be numeric.
At first I was using the following, which allows all the characters to be alphanumeric:
var re = /^[A-Za-z0-9 :\\_]$/;
if (event.change.length >0) {
if (event.willCommit == false) {
    if (!re.test(event.change)) {
        event.rc = false
That works fine, but it's not quite what I needed. With some assistance I changed it (see below) to fit what I was looking for. However, this didn't work; it prevents anything from being entered in the field:
var re = /^[A-Za-z0-9]{2}\d{7}$/;
if (event.change.length >0) {
if (event.willCommit == false) {
    if (!re.test(event.change)) {
        event.rc = false
Any help would be greatly appreciated.
Thanks...

Here's a function you can call form the field's custom Format script. It should be placed in a document-level JavaScript:
function custom_ks1() {
    // Define non-commited regular expression
    var re = /^[A-Za-z0-9]{0,2}([0-9]{0,7})?$/;
    // Get all of the characters the user has entered
    var value = AFMergeChange(event);
    // Allow field to be cleared
    if(!value) return;
    if (event.willCommit) {
        // Define commited regular expression
        var re = /^[A-Za-z0-9]{2}[0-9]{7}$/;
        if (!re.test(value)) { // If final value doesn't match, alert user
            app.alert("Your error message goes here.");
            // event.rc = false
    } else { // not commited
        // Only allow characters that match the regular expression
        event.rc = re.test(value);
Call it like this:
// Custom Keystroke script
custom1_ks();

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.

Checking valid e-mail's using Regular expressions

Hey buddies ,
I desperately need some help here. I need to develop a generic method that wiull use regular expressions and patterns to validate an e-mail.
Does anyonw have any idea on how to do this. And if possible please share some code with me.
Thanks a lot

You can do regular expresions in java using java.util.regex.*:
import java.util.regex.*;
   Pattern p = Pattern.compile("\\S++\\s++");
   Matcher m = p.matcher(sInputLine);
   if(m.find()){
      sUser = m.group().trim();
   }For more info on regular expressions in java, check out the javadocs:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html

Searching for a substring using Regular Expression

I have a lengthy String similar to repetetion of the one below
String str="<option value='116813070'>Something1</option><option value='ABCDEF' selected>Something 2</option>"I need to search for the Sub string "<option value='ABCDEF' selected>" (need to get the starting index of sub string) and but the value ABCDEF can be anything numberic with varying length.
Is there any way i can do it using regular expressions(I have no other options than regular expression)?
thanks in advance.

If you go through the tutorial then you will find this on the second page:

                console.format("No match found.%n");
}It's does everything you need and a bit more. Adapt it to your needs then write a regular expression. Then if you have problems by all means come back and post them up here, but first at least attempt to solve it yourself.

ADF Email Validation using Regular Expression

Hi,
Wanted to add Email Validation VO search.
It is working if i put
<af:validateRegExp pattern="[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}"
                                         messageDetailNoMatch="The value {1} is not a valid email address:"/>However this requires email id to be entered in Capital Letters.
Tried with below option is not working.
               <af:inputText value="#{bindings.xxEmail.inputValue}" label="Email"
                                      required="#{bindings.xxEmail.hints.mandatory}"
                                      columns="#{bindings.xxEmail.hints.displayWidth}"
                                      maximumLength="#{bindings.xxEmail.hints.precision}"
                                      shortDesc="#{bindings.xxEmail.hints.tooltip}" id="it5">
                            <f:validator binding="#{bindings.xxEmail.validator}"/>
                            <f:validateLength minimum="6"/>
                            <af:validateRegExp pattern="[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}"
                                         messageDetailNoMatch="The value {1} is not a valid email address:"/>
                        </af:inputText>I got above info from

The RegEx to check EMail after RFC2822
[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?There are still some missing parts in the check as not all suffix combinations are allowed, but this is pretty good.
