Regex :: Exclude A String Anyhwere In Pattern From Matches?
Apr 4, 2011
I need to write a regex which will match URLs that do not have a specific query string name/value pair anywhere in its URL. All other query string names, and all other query string values with the same name should be matched. Other pages in the same directory (or sub-directories) should not be matched.URL...The query string name and value that I need to exclude from matches is:[code]How can I prevent matches when the string exists anywhere in the pattern?
I 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):
var regEx:RegExp = new RegExp(/(?:^|s)(#[^s$]+)/g); var txt:String = "This #asd is a test tweet #hash1 test #hash2 test"; var matches:Object = regEx.exec(txt); trace(matches);
The trace returns '#asd,#asd'. I really don't understand why it would to this, as in my RegEx testing application 'RegExhibit' it returns '#asd,#hash1,#hash2', which is what I'd expect.
I have the following regex, which will match all the <br> and <br /> tags in a string:
/<br[s|/]*>/gi
I actually want to match every set of two consecutive tags, with valid matches being:
<br><br> <br/><br> <br><br/> <br/><br/> (and all variations with a space before the slash)
Obviously I can just double up the expression to /<br[s|/]*><br[s|/]*>/gi, but is there a shorter way of taking the first expression and saying "this, but twice"?
i'm trying to search a string for a particular pattern, and replace it with elements from within the pattern... for example..here's the given string...if you want to learn how to use regexp, {url===http://somesite.com, text===click here}.
the pattern... {url===http://somesite.com, text===replacement text}
and the intended result... if you want to learn how to use regexp, click here.
of course, i'll extract the url and do something else with it... i'm just wondering what the regexp is for that pattern, and how i can extract things from the results returned.
In Actionscript and Adobe Flex, I'm using a pattern and regexp (with the global flag) with the string.match method and it works how I'd like except when the match returns multiple occurrences of the same word in the text. In that case, all the matches for that word point only to the index for the first occurrence of that word. For example, if the text is "cat dog cat cat cow" and the pattern is a search for cat*, the match method returns an array of three occurrences of "cat", however, they all point to only the index of the first occurrence of cat when i use indexOf on a loop through the array. I'm assuming this is just how the string.match method is. I want to find the specific indices of every occurrence of a match, even if it is of a word that was already previously matched.
Trying to replace a portion of a string with a "-" if it matches a string variable in AS3.
var re:RegExp = new RegExp(imageArray[j][1],"gi"); trace(imageArray[jTemp][2].replace(re,"-"));
imageArray[jTemp][2] is a string imageArray[j][1] is a string as well I'm not getting the result I expect. I would like trace above to return 'permanentContainer-' Here are the traces for the above variables
I'm trying to work with RegEx to split a large string into smaller sections, and as part of this I'm trying to replace all instances of a substring in this larger string. I've been trying to use the replace function but this only replaces the first instance of the substring. How can I replace al instances of the substring within the larger string?
I have absolutely no knowledge in Regex whatsoever. Basically what I'm trying to do is have an error class that I can use to call errors (obviously) which looks like this:
package avian.framework.errors { public class AvError extends Object {
[Code].....
The idea is to replace {0} with the first parameter parsed in ...params, {1} with the second, etc.
I've done a bit of research and I think I've worked out that I need to search using this pattern:
I have a text field within Flash that contains a block of (obviously) text. What I want to do is perform a search on the content of the text field that returns the x & y coordinate and the width & height of the found text. The result will be used to place a visual element over that portion of the text box.
For example: var pattern:RegExp = /d+/g; var found:Array = box.text.match(pattern); var i:String; for each(i in found) { /** * Find the x, y, width, height of the matched text in the text field * Use result to place transparent yellow box around text */ } Which visually should result in something like:
Is there some way in flex to parse strings to date. I want it to support custom formats similar to 'dateformatter'. Using 'dateformatter' class we can parse date object in various string formats as specified by 'formatString property'. I want it other way round, from string to date. The parse method 'Date.parse(my_string)' does string parsing but for a very limited set of formats. Can't we have something similar to following, where user can specify his/her own formats.
I've read some documentation about regular expressions in AS3. I was wondering if it is possible to check every word of a string for a pattern. If all the words satisfy the pattern, the test is passed, otherwise is failed. [code]
I tried to use it and it returns null, although the same string tested on RegExr works fine:
var linkRegEx:RegExp = new RegExp("(https?://)?(www.)?([a-zA-Z0-9_%]*).[a-z]{2,4}(.[a-z]{2})?((/[a-zA-Z0-9_%]*)+)?(.[a-z]*)?(:d{1,5})?","g"); var link:String = 'generic links: www.google.com http://www.google.com google.com';
I have a string that is similar to a path, but I have tried some regex patterns that are supposed to parse paths and they don't quite work.
Here's the string f|MyApparel/Templates/Events/ I need the "name parts" between the slashes. I tried (w+) but the array came back [0] = "f" and [1] = "f". I tested the pattern on [URL] and it seems to work correctly.
Here's the AS code: var pattern : RegExp = /(w+)/g; var hierarchy : Array = pattern.exec(params.category_id); params.name = hierarchy.pop() as String;
I'm new to actionscript and i cant seem to get the regex syntax right in actionscript3. The task is straight forward, i want to make sure that the first two characters in a given string are alphabets and nothing else.[code]
I don't know anything about regular expressions and I don't really have the time to study them at the moment.I have a string like this:test (22/22/22)I need to capture the test and the date 22/22/22 in an array. the test string could also be a multiple words string:test test(1) tes-t (22/22/22)should capture test test(1) tes-t and 22/22/22I have no idea how to get started on this. I managed to capture the date string with the parentheses by doing:(.*)but that really doesn't get me anywhere.
In the below code if i replace st2 into the pattern of regexp without quotes, it works fine.Now since i get the regular expression from some other file, as it is shown in st2. I want to add that into the regexp pattern. But as in the below code it doesnt work.
<fx:Script> import mx.controls.Alert public function onClicking(){
I want to know if is possibile through regularexpression, count the numbers contained into a string and add a specified character near it.
For exemple, this is a string: Hello2all821abc13 This string contain 3 numbers: 2, 821 and 13 (note that the numbers contained into 821 and 13 are considered like an unique entity, not signle). I want to add near each of it the "-" symbol. Is it possible?
I rarely use regular expressions and still have a hard time reading/writing them sometimes (getting better, though), but I came across a situation where I needed to split up sentences in a text file and store each sentence as a separate item in an array.
To do this, I have tried to use the split() function by passing it a regex to detect ends of sentences... for most cases, anyway, which includes ., !, or ?, optionally followed by " or )
(What this code does is split on condition of a blank space but only where it finds a preceding/prefix that includes end punctuation, plus a lookahead/suffix that contains the beginning of a sentence, such as a capital letter)
The problem is that this doesn't seem to work. It works like a charm when I test it in Expresso free regex writing and testing software), but then when I try to send it to the split, it doesn't split the items. Do I need to do escapes for special characters when sending regex input to a split?
How to create an array from a string. The string will look something like this:
Code: Main Idea -Idea 1 --Idea 1 sub point 1 -Idea 2 --Idea 2 sub point 1 ---Idea 2 sub point 1 subsub 1 ---Idea 2 sub point 1 subsub 2 --Idea 2 sub point 2 -Idea 3
Each "-" indicates a child relationship or 'Sub'. Each child can have any number of children which can have any number of children.
I've read some documentation about regular expressions in AS3. I was wondering if it is possible to check every word of a string for a pattern. If all the words satisfy the pattern, the test is passed, otherwise is failed. Here is an example of what I mean:
Code: var reg:RegExp = /[a-z]/i; var str1:String = "a b"; var str2:String = "a 1";
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?
I would like to be able to replace a section of a string with a dash. The section being replaced will be variable.
var str:String = "permanentContainer-temporaryContainer-" var test:String = "temp"; var pattern:RegExp = /-[(+test+)]+-/i; trace( str.replace(pattern,"-"));
