I'm writing a HTML parser in Flex (AS3) and I need to remove some HTML tags that are not needed.
For example, I want to remove the divs from this code:
<div>

I want to alter the text color inside a string that has some HTML tags using regular expressions.My question is how can I alter the letters only of the text between html tags and not inside the html tagsI am using something like this:
ActionScript Code:
var exp:RegExp = new RegExp(textfield.text,"i")
str = str.replace(exp, "<font color='#FF0000'>$&</font>");

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);

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 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'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?
use regular expression. i want to remove content between html tags.example:
Quote: This is test content <img display='false' src="angry.gif"> image. </img>.i want to remove all the image tag which have display attribute false.
I'm looking for a regular expression that can remove all the following characters from a string (and Whitespace too): ~ % & ; : " ' , < > ? #

I wrote a function to override y FLEX LineChart's datatips because the default datatips were ugly and rather boring.I finally set the style I wanted but am now having some problems removing un-necessary tags from being displayed in the custom datatips.For example, the datatips now display things like this:
"<b>Humidity</b></BR>2010-07-05T00:15:00"
I can always perform a "Replace()" to remove those break and bold HTML tags, but that seems really un-necessary and anti-development.I am using this to set the dataTip's label text:
var hd:HitData = value as HitData;
var item:LineSeriesItem = hd.chartItem as LineSeriesItem;
_xAxisText = String(hd.displayText + ' ' + item.xValue);

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?

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.

View 10 RepliesI 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.

View 2 RepliesI 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.
I'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. ()$), the search function returns (-1). How can I escape these characters?
Code:
// with path="hello$world" and pattern="hello$" this returns -1
function checkPath (pattern:String):int
{
var reg:RegExp = new RegExp(pattern);
return path.search(reg);
}
I am pulling data from an xml file which has HTML tags in it. I need the HTML tags for the on-screen display, but I am also using printJob to print what's on the screen. The problem I'm having is that when I run printjob it prints all the HTML too. Is there a way to remove the HTML tags? Maybe some sort of script? I'm thinking I could search for the beginning "<" and the end ">" and remove them and what's in between, but I'm not really sure how to go about this.

I'd like to remove the font tags from the htmlText string produced by a TextField leaving the surrounding nodes and any bold etc tags within intact.
Example partial output of htmlText:
<P ALIGN="LEFT"><FONT FACE="ChampagneLimo" SIZE="18" COLOR="#000000" LETTERSPACING="0" KERNING="0">Lorem Ipsum</FONT></P>
My plan was to avoid trying anything with regex and create an XML object.
However if I create a new XML object containing a root node and then attempt to appendChild the htmlText string so that I have a valid XML object to manipulate I run into a problem with html entities, see example below:
<html><P ALIGN="LEFT"><FONT FACE="...
How can the font tags be stripped from htmlText and how can I create a valid XML object from the htmlText string? My plan was to use the XML replace() method

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.

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?
