I learn best by example, and I tried piecing it together by comparing the regex match above, to a URL in between hreft" and </a> - but I couldnt do it. Ive been working on this project for a while, and im getting tired.
Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.
This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.
I am trying to extract data from a string using Regex in VB.net This is my string CN=firstname lastname/OU=orgunit/O=org;shortname I am basically trying to retrieve firstname lastname (together),orgunit,org and shortname
How would I use Regex to extract the body from a html doc,taking into account that the html and body tags might be in uppercase, lowercase or might not exist?
I am parsing a file which contains customer address in the following 2 formats:
Format #1 12345 Melrose Place New York NY USA 12987
[Code]...
I need to put the data into Address, City, State and Zip fields. I am able to parse and put the data (specifically line 2) in the fields for format #1 but am having issues doing the same for format # 2 because format # 2 doesn't have USA as a reference point.
I have a project that uses regex, and while matching strings and regex syntax is working well [If rx.IsMatch(test) Then], i'd like to know (if any) a way to use regex to extract all instances of a pattern.
I was able to extract href value of anchors in an html string. Now, what I want to achieve is extract the href value and replace this value with a new GUID. I need to return both the replaced html string and list of extracted href value and it's corresponding GUID.
My existing code is like: Dim sPattern As String = "<a[^>]*hrefs*=s*((""(?<URL>[^""]*)"")|('(?<URL>[^']*)')|(?<URL>[^s]* ))"
.net framework 2 vs 2008?I need to extract a string from website. Loading a site in a big string works perfect.

I have been stumped on this for about 3 weeks now. In the beginning me and my partner have been trying to hit this at the internal angle. only problem is different html tables are constructed different than others. We are needing to extract from multiple pages and sites so we know that Regex will be the best solution. We can use the same script for everything. This is my first time working with Regex, I got it actually extracting the very first ip[proxy]. I have no idea why it isn't extracting every one on the page. I also have to add the . in between each each octave of the ip. That is weird because I have it in the Regexpession to find the .'s.What I'm Needing is for this to basically scan the whole page and grab all the ipsorts and add them to a listbox.Here is my
Dim request As HttpWebRequest = Nothing Dim response As HttpWebResponse = Nothing Try
I am trying to extract everything between the body part as I am building a forum crawler and since all the user posts are between the <body></body> I have chosen to experiment with Regex. So far I have coded the following but sort of stuck on how to output the result say in a textbox? Also I am not sure if the body part of the regex is correct.
Dim URL As String = Textbox1.Text Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("URL") Dim response As System.Net.HttpWebResponse = request.GetResponse Dim streamReader As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream()) [Code] .....
I have this sql statement: CREATE TABLE [dbo].[User]( [UserId] [int] IDENTITY(1,1) NOT NULL, [FirstName] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, [MiddleName] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_A
What I want is regex code which I can use to get all fields and data type. So will return something like that: FirstName varchar MiddleName varchar The sql statement will always have this format. I am using .Net to run this regex
I want to check if a Vb.net string contains at least 3 non white space characters of which at least one non numeric character. i dont know creating the regular expression for it?
Has anyone created a regex that matches each of the cell references in a given Excel formula? I'm trying to extract a list of cell references into an ArrayList from a provided Excel formula. Ideally, the ArrayList would also preserve any cross-tab or cross-workbook reference information. The key is for the regex to be compatible with any potential Excel formula, as the formula will change with each use.This seems to capture cross-workbook references:
Still getting to grips with regex and have seen a few samples about that give me most of what I need so asking for opinion on this. I need to extract x words from a single line, so the regex could use w+ to get characters, however my line may contain anything inside the word like:
what i am trying to do is extract information beween two tags in some html from the source of a website. The contents of the text between the two tags will always be different. the code i currently have is;
I've used regular expressions in the past. I have an app that parses a .csv file and replaces certain characters (commas). Here's an example.. item1, item2, item3, fruits are apples, oranges, grapes. Squash is a vegetable, not a fruit. What my app does is search each line between character1 and character18 and replace all "," with "~". How this is done through regular expressions?
I have to process a string that could include all sorts of non-standard characters and I've been asked to provide a regular expression that will match and remove all characters that are non-alphanumeric except punctuation and spaces. Is there a way to do this?
To search a pattern containing parenthesis, they must be escaped using backslashes. So to search for (Streetname) you must use (Streetname). If you don't use , whatever is between () will be retained and available for reference through the variables $1, $2 etc... Exemple, in the sentence "It's worth noting that (StreetName) can be anything...(Post), (TreeStump)", $1=StreetName, $2=Post, $3=TreeStump
I am trying to split a data field in VB using the split function.
The data field has the following character strings"&|:"
which I need to base my split on.
Dim elements As String() = Regex.Split(dataField, "&|:") field1 = elements(1) field2 = elements(2)
The field1 and field2 still have a trailing "&|" chracters.How do I check if the field1 and field2 have these trailing characters? How do I delete them?PS - I have tried "&\|:" as the delimiters in the split function which did not work.
I 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.
