What I'm trying to do is parse out some links via a google search and fill a text box with said results. This is the code I have in a module which I call upon inside of a command button.
Imports System.Text
Imports System.Text.RegularExpressions
Module Module1
[CODE]...
I need to function in my program that when I click a button, it checks the text of textbox1 for links (only the text that starts with [URL]
so if I enter this:
[URL]
I'm just curious as to how some software programs that I see out there have the ability to extract links & text from thousands of web pages at an extremely high and fast rate. Has anyone here, ever created a link or text extracting program the has the ability to parse many webpages and return data into a textbox? I know how to extract links via the webbrowser control, but it doesn't seem to parse/extract data at a very high & fast rate like many email, link & text extracting programs that I see out there.

I have a string which i need to parse using Regex class of System.Text.RegularExpressions. I need to find if the first 2 characters of the string are either "00" or "07" or "16" or "23".
View 1 RepliesI'm attempting to parse a text file containing several Windows paths; I'd like to use regular expressions if possible, and I'm using VB.NET.The file is formatted somewhat like so:
M - Network Mode
C:ClientSystem - System Path
C:ClientProducts - Product Path

I'm messing around with regular expressions and I can't seem to figure out how to parse this file.It's basically a lua file containing a table like:
TableName = {
["QuotedString"] = {
["QuotedString"] = {
[code]....
Some things with the file are standard, like the "TableName" (Never in quotes) starts the table. Variables always have [" "] around them and then equal something like ["Test"] = 0. However, the variable could have multiple variables within it. split up the file within each {} and then try to parse each ["QuotedString-Key"] = 0?

View 13 RepliesSimply put, I have a text file full of reg values. I want to search the text file for X number of reg values. I want to then, have those values and their dword values (whole line + next 3 to 4 lines in the file) listed in either another text file or an Excel spreadsheet. Regardless of the format, I would like to have the values sectioned off for each of the values searched (probably tables of some sort).[code]...
View 1 RepliesI certain html page contains links that are displayed with each onclick event. I am unable to parse the html for the url that will follow these onlick links. If this is the source on the page, how do I capture the content that each onclick link displays. In other words for example:

Now this is the onclick link that will display some content which I need to capture. Basically I want to be able to activate the onclick event from a program to display and capture the url links from that specific page.
I'm working on a program that gets some info about a certain web page. But one of the features is it needs to find all the links to other webpages on THE SAME site (I think its called an internal link... not sure).

View 1 RepliesI want to search a sql server database from VB.Net and output the results in a Listview. I don't want to use code that involes queries in it, but the queries are to be used in the data set designer, i.e the query builder.Here's what I got so far.
I created a query in the builder called SearchStudent
SELECT FirstName, Surname, Email, PredictedGrade, Notes

WHERE (FirstName LIKE @FirstName) OR
(Surname LIKE @Surname)

I am trying to remove the tables within an HTML file, specifically, for the following document, I'd like to remove anything within the tags <TABLE....> and </TABLE>. The document contains multiple tables with texts in between.
The expression that I came up with, <TABLE.*>s*[s|S]*</TABLE>s*, however would remove the text in between the tables. In fact it would remove everything between the first <TABLE> and the last </TABLE> tags. I would like to keep the texts in between and only remove the tables.

I'm writing a little web service which generates SO/SF/SU/MSO user flair in the form of an image with various "themes". I find this preferable to using the HTML/JS solutions offered by SO as it's more flexible and also works better in forum signatures.
I'm retrieving the data using the apparently unofficial API (More info here). I can have the data in HTML or JSON. I assumed the JSON would be easier to parse.
Unfortunately, I'm not great at regexes. and the best I can come up with is some very hacky sub-stringing. I believe a regex should be the most elegant solution
regex that matches ID, GravatarURL, ProfileURL, DisplayName, Reputation and Badge Counts (Bronze/Silver/Gold).
FWIW This is to be used in a VB.Net project (in case that affects the syntax at all)
[Code].....
In case any of you are interested, some screenshots of the flair as a work in progress are available here: Me, Jeff Atwood, Joel Spolsky
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?
Has anyone ever done this? Is there a tutorial somewhere?
View 1 RepliesProblem: Current regex pattern does not filter all lines. Adding ^ to the beginning and $ to the ending of the pattern seems to break it as well. If I try it ont gives partial results using options(multiline & case insensitive). Using it in the application returns nothing at all.

Part of my project is to retrieve a string variable from an external source (google docs) and parse it. This string represents width and height. I have no problem retrieving, I just need to parse it in to two strings. The string has 4 variations.
Here are examples:
3"x4"
3"hx4"w
3hx4w
3x4
The width is always the first number and the height is always the second. Sometimes, the width and height have decimal points. Any way to parse this into two strings of the numeric values only?
I have written code to pull some data into a data table and do some data re-formatting. I need some help splitting some text into appropriate columns.
CASE 1
I have data formated like this that I need to split into 2 columns.
[Code]...
column is the first 11 characters That is easy.column 2 should contain all the text after the first 11 characters up to but not including the first number.The last column is all the text after column 2
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)

View 2 RepliesI'm trying to find a good way to parse through text and only get certain matches, like say someone puts the text "My name is Bob" in a textbox, then it puts the text "<Tag>My name is Bob</Tag>" in another textbox, and my problem is, if that person were to put..."My name is </Tag> Bob" in the textbox, when the RegEx match is found, you would only get "My name is" as a match. So how can I make sure that the text input no matter what it is will not interfere with the <Tag></Tag> when using the RegEx:
(?<=(<Tag>).+?(?=(</Tag>))
