i'm really new at the VB language only been doing for around 2 weeks.I hoping someone can help me with this, how would i get this USERNAME, USERID from a string
Adding the USERNAME to listbox, and then USERID into an array separated by a space. - I no how to do this part just the regex above remember i've only been doing for two weeks so i'm not very knowledged at this.
how would i get this USERNAME, USERID from this string:
Code:
<a href="javascript:attackWindow('USERNAME','USERID','50','RANDSTRING', 'RANDSTRING2')">
Adding the USERNAME to listbox, and then USERID into an array separated by a space.
I've been working with Regex and I've run into something that doesn't make sense to me; I either misunderstood how the Multiline option works, I'm not using it right, or it really just doesn't work like it's supposed to. This is a little test I made:

View 3 RepliesRegex in VB2008.I have a file system directory that my code is watching. When a file is placed in that directory my code kicks off a processing application. Based on the filename structure, the code will perform different processes. So I need to match the filename structure specficially to get the correct processes to run on that file.My file name structure is: IK2YYYYMMDD_VV.e;where YYYYMMDD is well, the year, month and day. And VV is a verison number from 00-99 If the new file saved in the directory match this structure then I want a TRUE returned. From a filewatcher I get the filename as an "e.Name" (FileSystemEventArgs) variable. My current code to see if it matches the baseline structure is;
Dim IKPred2Match as New Regex ("^IK2.*\.e$") Dim ValidIKPred2Match as MatchCollection = IKPred2Match.Matches(e.Name)I've tried many different regex match patterns, and just can't seem to find the magic one.
I need an extremely simple regex pattern that matches anything within square brackets [].
Example:
This is a [test] text with [some] [examples].Required results: [test], [some], [examples].I don't want to get rid of the brackets, they should be included in the result (that should make it easier, right?)
If possible I'd like to exlude results that have whitespace in them, so things like [this string] should not be matched. If that gets too hard (probably not, but hey I can't even manage this :S) then I don't really mind, I can always check if the result contains whitespace myself.
I tried a lot of examples I could find online and ones that I could think of myself but none work. Note: I've been testing with the Visual Studio Find dialog (checking to use regular expressions obviously), maybe that's where the problem lies, because I don't really understand why some of these don't work...
Anyway, first thing I tried was simple: match the two brackets and one or more characters in between (that should be a +, right?)
I'm using VB.Net in an ASP.Net 2.0 app to run some regular expressions that remove some unnecessary markup. One of the things that I'd like to do is remove span elements that don't have any attributes in them:[code]I'd like to remove the outer span elements. Unfortunately, my regex above gives me this as a result, since the closing span matches the first one it comes across:[code]
View 4 RepliesI want to use Regex.Replace to replace a Match with a context sensitive value. I use the MatchEvaluator for this. But to make things simpler lets say I'm matching %v I want %v to be escapable, so if I use \%v it will not match. Anything else should match.
The pattern I came up with is this: (?:[^\]|^)%v It basically matches %v if it occurs at the beginning of the string, or if it follows any character except . It doesn't capture the first part of the expression.I know this isn't the "right" way to do it. But it worked just fine until I noticed that when I use this pattern in a replace, it includes the character before %v in the replacement(duh, right?)So, if I have ThisIsAValue:%v and I do Regex.Replace, replacing with the string Value, my result will be ThisIsAValueValue instead of ThisIsAValue:ValueI've tried googling this but the fact that "escape character" is so heavy in RegEx, all the results are geared towards the USAGE of escape characters instead of picking them out with a pattern.
I am using vb.net to parse my own basic scripting language, sample below. I am a bit stuck trying to deal with the 2 separate types of nested brackets.
Assuming name = Sam
Assuming timeFormat = hh:mm:ss
Assuming time() is a function that takes a format string but
has a default value and returns a string.
[code]....
I could in theory change the syntax of the script completely but I would rather not. It is designed like this to enable strings without quotes because it will be included in an XML file and quotes in that context were getting messy and very prone to errors and readability issues. If this fails I could redesign using something other than quotes to mark out strings but I would rather use this method.
Preferably, unless there is some other way I am not aware of, I would like to do this using regex. I am aware that the standard regex is not really capable of this but I believe this is possible using MatchEvaluators in vb.net and some form of recursion based replacing. However I have not been able to get my head around it for the last day or so, possibly because it is hugely difficult, possibly because I am ill, or possibly because I am plain thick. I do have the following regex for parts of it.
Detecting the parentheses: (w*?)((.*?))(?=[^(+)]*((|$))
Detecting the square brackets: [[(.*?)]](?=[^[+]]*([[|$))
which is the way to create all "matches" to array without this style:
ListBox1.Items.Add(Regex.Match(GetWebData).Value)
ListBox1.Items.Add(Regex.Match(GetWebData).NextMatch)
ListBox1.Items.Add(Regex.Match(GetWebData).NextMatch.NextMatch)
I'm currently writing a library where I wish to allow the user to be able to specify spreadsheet cell(s) under four possible alternatives:
A single cell: "A1";
Multiple contiguous cells: "A1:B10"
Multiple separate cells: "A1,B6,I60,AA2"
A mix of 2 and 3: "B2:B12,C13:C18,D4,E11000"
Then, to validate whether the input respects these formats, I intended to use a regular expression to match against. I have consulted this article on Wikipedia:
Regular Expression (Wikipedia)
And I also found this related SO question:regex matching alpha character followed by 4 alphanumerics.Based on the information provided within the above-linked articles, I would try with this Regex:
Default Readonly Property Cells(ByVal cellsAddresses As String) As ReadOnlyDictionary(Of String, ICell)
Get
Dim validAddresses As Regex = New Regex("A-Za-z0-9:,A-Za-z0-9")
[code]....
1. Is my regular expression correct? If not, please help me understand what expression I could use.
2. What exception is more likely to be the more meaningful between a FormatException and an InvalidExpressionException? I hesitate here, since it is related to the format under which the property expect the cells to be input, aside, I'm using an (regular) expression to match against.
I'm trying to find a way where i can make it loop through the results of my capture group regex query.
For instance if i have this:
VB.NET
Dim matches = Regex.Matches("<h1><span>test</span></h1>", "(?<=<h1>(<span>)?)(?<data>.+)(?=(</span>)?</h1>)")For Each item In matches.OfType(Of Match)()Console.WriteLine(item.Value)Next
And i'm trying to get the contents of <data>, how do i do it without it printing out the junk before it and after it?
quantifier isn't working, its supposed to make the <span> tag optional in the query, but it isn't.
I want to check each of the strings in an array (currently in a hashtable, but that shouldn't necessarily matter right?) with the user's input, if the words in each of them match. This might have sounded a little tricky so let me elaborate.
Problem: Comparing an input string with a collection of strings, and know which string in the collection matches the input string the most - based on words. What I'm trying to do here is a chatbot that works with keywords. For example, in the bot script, you could find "HOW ARE YOU" and the response "I am fine." If the user then sends input to this bot, it could look like this: [Code] This may not sound like a tricky thing, but the tricky part comes when I want to know which of the strings (e.g. "HOW ARE YOU") match the input string the most, based on the words.

View 1 RepliesI am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].

This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?

I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?
