[Flex 4.5.1] Regular Expressions - how to ignore case for cyrillic text /ignore flag doesn't work/ ?

The only solution to this that I've found is to convert the text to lowercase before matching...
Is there a more convenient way ?
Thanks

Regular expression in a switch case

Hey guys,
I have a string "52x + 60" and i want to extract 52x and 60 using regular expressions and a switch case
Is this the right way of doing it?
var equation:String = "32x + 5"
var numberExract:RegExp = /\d+/
var xExtract:RegExp = /d+/x/
for(var i:Number=0; i<equation.length; i++)
                    switch(equation.charAt(i))
                              case numberExtract.exec(equation):
                              trace("number");
               break;
               case xExtract.exec(equation):
               trace("x");
               break;
Because it's not tracing anything when i try

Here is a quick and dirty approach - can be customized, optimized and more elegant expressions used:
// equation
var string:String = "x^2 + 5x + 5 - x7 + 8 / 4";
// value replacing xs
var value:Number = 60;
// replace xs with value
// if x comes after digit
string = string.replace(/(?<=\d)x/g, String("*" + value));
// if x comes before digit
string = string.replace(/x(?=\d)/g, String(value + "*"));
// all other xs
string = string.replace(/x/g, String(value));
// remove spaces
string = string.replace(/\s/g, "");
// get pairs with first level math
var pattern:RegExp = /(\d+[\*\^\/]\d+)|\D|\d+/g;
var result:Number = stringToMath(string.match(pattern));
trace("result", result);
function stringToMath(match:Array):Number
    // digits surrounding operator
    var pattern:RegExp = /\d+\D\d+/;
    for (var i:int = 0; i < match.length; i++)
        if (match[i].match(pattern))
            match[i] = String(calculate(match[i]));
    trace("loop result", match);
    return calculteSum(match);
* Calculates sums
* @param    array
* @return
function calculteSum(array:Array):Number
    var result:Number = array[0];
    for (var i:int = 1; i < array.length - 1; i++)
        if (array[i] == "+")
            result += array[i + 1];
        else if (array[i] == "-")
            result -= array[i + 1];
    return result;
* First level math
* @param    string
* @return
function calculate(string:String):Number
    var operator:RegExp = /[\+\*\/\^\-]/g;
    var digits:Array = string.match(/\d+/g);
    var num:Number = 0;
    if (digits && string.match(operator) && digits.length > 1)
        switch (string.match(operator)[0])
            case "*":
                num = digits[0] * digits[1];
                break;
            case "/":
                num = digits[0] / digits[1];
                break;
            case "+":
                num = digits[0] + digits[1];
                break;
            case "-":
                num = digits[0] - digits[1];
                break;
            case "^":
                num = Math.pow(digits[0], digits[1]);

If the sleep/wake button doesn't work use the home button and if the home button doesn't work it's the other way around, however if both of them don't work charge it with your connector connected with your computer or wall socket and it will turn on. Hope this helps.

Regular expressions-how to replace [ and ] characters from a string

Hi,
my input String is "sdf938 [98033]". Now from this given string, i would like to replace the characters occurring within square brackets to empty string, including the square brackets too.
my output String needs to be "sdf938" in this case.. How should I do it using regular expressions? I tried several possible combinations but didn't get the expected results.

SQL Injection and Java Regular Expression: How to match words?

Dear friends,
I am handling sql injection attack to our application with java regular expression. I used it to match that if there are malicious characters or key words injected into the parameter value.
The denied characters and key words can be " ' ", " ; ", "insert", "delete" and so on. The expression I write is String pattern_str="('|;|insert|delete)+".
I know it is not correct. It could not be used to only match the whole word insert or delete. Each character in the two words can be matched and it is not what I want. Do you have any idea to only match the whole word?
Thanks,
Ricky

Avoid dynamic sql, avoid string concatenation and use bind variables and the risk is negligible.

Regular expression: how to match "[somestuff]"?

I have a problem with the following code.
I meant to catch "[fm1,-]". But I got "[fm1,-] funder [fm2,-] of our country. [sn8,s-]" instead.
import java.util.*;
import java.util.regex.*;
public class regPractice {
public static void main(String[] args) {
String s="<TITLE Getting to Know> I hope suitabe [fm1,-] funder [fm2,-] of our country. [sn8,s-]";
Pattern p=Pattern.compile("\\[(.*)\\]");
Matcher m=p.matcher(s);
if (m.find() ){
System.out.println(m.group(0) ) ;
}else{
System.out.println("Nothing");
}

Regular expressions are greedy - that is (.*) will grab as much as it
possibly can before a ]. Hence you see what you see.
What you want is a reluctant quantifier, in this case (.*?)
These grab as little as they possibly can. The parentheses are also
not needed in your example, but you may want group(1) for some
other reason.
So we end up with:import java.util.regex.Matcher;
import java.util.regex.Pattern;
public class regPractice {
    public static void main(String[] args) {
        String s = "<TITLE Getting to Know> I hope suitabe [fm1,-] funder [fm2,-] of our country. [sn8,s-]";
        Pattern p = Pattern.compile("\\[(.*?)\\]");
        Matcher m = p.matcher(s);
        if (m.find()) {
            System.out.println(m.group(0));
        } else {
            System.out.println("Nothing");
}which gives the desired output.
The different types of quantifier are described here:

Regular expression - find if string does NOT contain text....

I have a string that I want to tokenize. The string can contain basically anything. I want to produce tokens for each "word" found, and for each "<=" or "," found. There does not need to be whitespace around a "<=" or a "," to consider it a token. So for example:
joe schmoe<=jack, jane
should become
joe
schmoe
<=
jack
jane
As a constraint, I do not want to use StringTokenizer at all, as "its use is discouraged in new code". http://java.sun.com/j2se/1.4.2/docs/api/java/util/StringTokenizer.html
Here's the code I plan on using for this:
    public String[] getWords(String input) {
        Matcher matcher = WORD_PATTERN.matcher(input);
        ArrayList<String> words = new ArrayList<String>();
        while (matcher.find()) {
            words.add(matcher.group());
        return (String[]) words.toArray(new String[0]);
    }The trick, though, is coming up with a working regular expression. The closest I've found yet is:
([^\s]|^(,)|^(<=))+|,|<=
but that produces the following:
joe
schmoe<=jack,
jane
I think what I need is to be able to find if a string does not contain the substring "<=" or "," using a regular expression. Anyone know how to do this, or another way to do this using regular expressions?

Try:
* Tokenizer.java
* version 1.0
* 01/06/2005
package samples;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
* @author notivago
public class StrangeTokenizer {
    public static void main(String[] args) {
        String text = "joe schmoe<=jack, jane";
        Pattern pattern = Pattern.compile( "((?:<=)|(?:,)|(?:\\w+))");
        Matcher matcher = pattern.matcher(text);
        while( matcher.find() ) {
            System.out.println( "Item: " + matcher.group(1) );
}May the code be with you.

Regular expression to covert pascal case to underscores

I am looking for a way to use the SQL regular expression support to convert some pascal text into underscore separated words.
For example:
IsComplianceActionPossible -> Is_Compliance_Action_Possible.
What I am confused on is how to get the capital letter back in the output.
select regexp_replace('IsComplianceActionPossible','[A-Z]','_') from dual
REGEXP_REPLACE('ISCOMPLIAN

Another option:

REGEXP_REPLACE('ISCOMPLIANCEA

Most likely it would fit OP's needs, howvever it will not work on one letter words in the middle:
SQL> select regexp_replace('HereIAm','(.)([A-Z])','\1_\2') from dual

REGEXP_R
Here_IAm

Regular expression help to solve sys_refcursor for a record

In reference to my thread Question on sys_refcursor with record type , I thought it can be solved differently. That is:
I have a string like '8:1706,1194,1817~1:1217,1613,1215,1250'
I need to do some manipulation using regular expressions and acheive some thing like
select * from <table> where
c1 in (8,1)
and c2 in (1706,1194,1817,1217,1613,1215,1250);Is it possible using regular expressions in a single select statement?

Originally, you said you were looking for something that produced the same result as
where   c1 in (8, 1)
and      c2 in (1706, 1194, 1817, 1217, 1613, 1215, 1250)that is, any of the c1s could be paired with any of the c2s.
Now it looks like what you want is
where     (     c1 = 8
     and     c2 IN (1706, 1194, 1817)
or     (     c1 = 1
     and     c2 IN (1217, 1613, 1215, 1250)
     )that is, c1=8 and c2=1250 is no good; neither is c1=1 and c2=1706.
In that case, try
WHERE     REGEXP_LIKE ( s
              , '(^|~)' || c1
                     || ':([0-9]+,)*'
                     || c2
                     || '(,|~|$)'
              )

How to trigger a MouseEvent from TLF, my test doesn't work

Hi,
      I run into a problem while using the Listener of TLF,
      Inside the TextFlow, I have several Paragraphs.
      What I wish to accomplish is to trigger a mouse Event, like ROLL_OVER, ROLL_OUT event , when my mouse is over a on one of the Paragraphs.
      I used to experiment a while , but never seem to work, just the examples below
      _textFlow.addEventListener(FlowElementMouseEvent.ROLL_OUT,onMouseHandler);
      _textFlow.addEventListener(FlowElementMouseEvent.ROLL_OVER,onMouseHandler);
       ///   which doesn't work.         i need the event response ,so i can manipulate the paragraph
private function onMouseHandler(e:FlowElementMouseEvent):void
     trace("onMouseHandler" + e.type );
     var para:ParagraphElement = e.flowElement.getParagraph();
     trace(para.textLength);
Thanks in   advance!!!

InDesign CS6 how to set justification for form text field?

Hi everyone,
I've been playing with the ability to create form for PDF file but I haven't figure out how to set a center justification for a text field. By default it's left. Same thing for font, the one selected in InDesign while creating the form isn't used when editing the form in Acrobat.
Do I need to create a paragraph style with a specific name to preserve both attributes?
Thanks.

InDesign CS6's forms features are great, but you're looking as version 1.0 of the feature. Those features cannot be set in InDesign.
Furthermore, if you try to pick a font other than the standard ones at the top of the menu, don't expect that your form users will be able to pick those fonts when they open up the form in Reader or Acrobat. I'm pretty sure that custom fonts are not stored in the PDF form.
