I'm using regular expression to search word in a string, for example
var patrn:RegExp = new RegExp("\bit's\b");
var str:String = "Heres my problem in it and it's so help me guys.";
trace(patrn.exec(str)); //result is null
My problem is I can't search the data in a string which has special character like ('/,/.). What regular expression string is capable solving my problem?
I need 3 different regular expressions one that finds at the beginning of the string a 'D' and a space then a name, so 'D patrickgates hello there' would return 'D patrickgates', or if all possible would return just 'patrickgates' one that will find the @ sign and a name together anywhere in the string so '@patrickgates hello, world' would work and return '@patrickgates' or if at all possible would return just 'patrickgates' one that will find 'RT' and a space and then '@' and the username at the beginning of the string so 'RT @patrickgates' would work if returning just the username and also being true isn't possible with one regex, then I could use one to match to, and one that will delete the 'D' or the '@' or the 'RT'.
View 2 RepliesWhat is the best (highest-performance/lowest memory-usage, etc.) way to compile a regular expression in AS3? [code]...

View 10 RepliesI have to parse out color information from HTML data. The colors can either be RGB colors or file names to a swatch image. I used [URL] to develop and test the patterns. I copied the AS regular expression code verbatim from the tool into Flex Builder. But, when I exec the pattern against the string I get a null. Here are the patterns and an example of the string (I took the correct HTML tags out so the strings would show correctly):

I have two strings.One looks like this.
Code:
[12] => Array ( [type] => 2 [name] => Width [value] => 3 )
The other looks like this.
Code:
[13] => Array ( [type] => 7 [name] => Blocks [value] => Array (
[0] => 4
[1] => 4[code].....
In those two strings, I need the Width value and the Block id value. Since the Width only has one value, I am going to put it in an int while the Block values are going into a Vector. Now...how in the world do I get the necessarily information out of this mess.

View 3 RepliesI need to match a string that begins and ends with the same character in flex...I know the long hand way (RE being - "a[^(a")]a" | "b[^(b")b" | etc...), but I'm positive this isn't what I'm required to do (midterm tomorrow!);
I need to do this in flex, but if you can think of a short regex for it, I may be able to convert it to flex notation.
What I was thinking of was something along the lines of -
%%
int firstChar;
%x string;
%%

But this bugs me in a few ways, first, having that variable makes this not a regular language; second, I don't know if you can even use a variable to in a pattern match; and third, I don't know how NOT to match it, if it's just a normal string. And third, I don't know how to return everything that's been matched while in 'string'

I need to convert Java regular expressions into Actionscript regular expressions. There apparently aren't any premade converters, so I'm trying to write one myself. Is there any resource that'd list all the differences? I'm aware of regular-expressions.info, but there doesn't seem to be a comprehensive listing of differences there.
View 2 RepliesI'm trying to use regular expressions with the String.replace() method to manipulate a string to replace all instances of a forward slash "/" with a period "."
So for instance, if I start with this String:
"things/stuff/cheese/yum"
I want to convert it to:
"things.stuff.cheese.yum"
Easy enough if I want to replace a letter... let's say I wanted to replace all instances of the letter "e", I would do this:
Code:
var str:String = "things/stuff/cheese/yum";
var myPattern:RegExp = /e/g;
trace(str.replace(myPattern, "."));
// returns: "things/stuff/ch..s./yum"
... but how do I replace all instances of "/"??
I am trying to find if a substring (pattern) is included in a string (path). I use the search method of String class, but if my pattern string includes regular expressions special characters (i.e. ()$), the search function returns (-1). How can I escape these characters?

// with path="hello$world" and pattern="hello$" this returns -1
function checkPath (pattern:String):int
{
var reg:RegExp = new RegExp(pattern);
return path.search(reg);
}

I've written a url validator for a project I am working on. For my requirements it works great, except when the last part for the url goes longer than 22 characters it breaks. My expression:/((https?)://)([^s.]+.)+([^s.]+)(:d+/S+)/i
It expects input that looks like "http(s)://hostname:port/location". When I give it the input: https://demo10:443/111112222233333444445
it works, but if I pass the input https://demo10:443/1111122222333334444455
it breaks. You can test it out easily at[URL].. Oddly, I can't reproduce the problem with just the relevant (I would think) part /(:d+/S+)/i. I can have as many characters after the required / and it works great. Any ideas or known bugs?

so im trying to figure out regular expressions in Flex, but cant for the life of me figure out how to do the following.From the sample below, i need to extract out only "Mike_Mercury".So i have to somehow strip out everything around it with RegExp, or whatever's best. Also, I would need it to work with other samples as well. Im getting this from the reddit api, so id have to extract that same section from a whole bunch of these.

I'm trying to find the number of newlines in a string using the Actionscript 3.0 RegExp engine. Using the string.match function and RegExp(" ","g") does not find the newlines in a string which contains newlines. Is there something I need to add to the pattern or something else that I am missing?
View 1 Repliesgive me the Regular Expression that can check if a given string has any HTML code in it, and coming to think of it I would be bothered with <a href="something">something</a> exactly.
View 2 RepliesAfter 2 nights of *almost* getting it I realized that Flash's RegExp doesn't support lookbehinds. Here are the 3 scenarios:
1) [URL]
2) <a href="http://example.com">http://example.com</a>
3) <br><br>http://example.com<br><br>
Basically what I want to happen is to ignore scenario #2. I know the solution, but I can't seem to nail it. All that needs to happen is to select the http (and everything after that) as long as it's not preceded by a "> or =", but since I don't know a way for RegExp to look backwards, I'm sort of at a loss. Here's hoping that someone has run into this issue before
I've been struggling with this problem for a while:I have a string containing HTML and I'm using a regular expression to get the characters between the tags. I'm then attempting to apply a TextFormat to those characters.The problem is that I'm using the TextField's "htmlText" property instead of it's "text" property (because I don't want the HTML tags to be visible). So, the character index that's returned from the regular expression is incorrect, when I apply the TextFormat.Here is some sample code which illustrates the problem:
var txt:String = "<b>Sample</b> string with bold text";
var tf:TextField = new TextField();
addChild(tf);

find the suitable regular expression to validate a string that has comma separated numbers, for e.g. '1,2,3' or '111,234234,-09', etc. Anything else should be considered invalid. for e.g. '121as23' or '123-123' is invalid. I suppose this must be possible in Flex using regular expression but I can not find the correct regular expression.

I have a situation where I might be getting one or both of a pair of characters and I want to match either.
For example: str = 'cddd a dfsdf b sdfg ab uyeroi'
I want to match any "a" or "b" or "ab". If the "ab" comes together I want to catch it as a single match (not as two matches "a" "b"). If I get "ab" it will always be in that order ("a" will always precede "b")
What I have is: /[ab]|ab/
But I'm not sure if the ab is going to be a stronger match term than the [ab].
