Regular expression question.

Guoqi Zheng

Sir,

I am writing a script to remove html tag using Regular expression.

For example, I have a string = "<td class="whatever " width=12>some content
here</td>"

What I want to return is "<td class="whatever " width=12>", I used pattern =
"<td(.*)>"

However instead of returning "<td class="whatever " width=12>"
it returns "<td class="whatever " width=12>some content here</td>"
Below is my code, what did I do wrong here?

Dim webPage As String = GrabUrl()
Dim abc As ArrayList = New ArrayList
RichTextBox1.Te xt = webPage

Dim TagExpression As New Regex("<td(.*)> ", RegexOptions.Ig noreCase)
Dim mc As RegularExpressi ons.MatchCollec tion

mc = TagExpression.M atches(webPage)

Dim m As Match

For Each m In mc
abc.Add(m.Group s(0))
Next

ListBox1.DataSo urce = abc

Kind regards

Regular expression question

by: Lee Kuhn | last post by:

I am trying the create a regular expression that will essentially match characters in the middle of a fixed-length string. The string may be any characters, but will always be the same length. In other words, as the regular expression (....)($) matches the "4567" in the string "1234567", how would I create a similar regular expression that only matches the "45" in the same string. The same regular expression would match "32" in the string...

Regular expression optimization

by: Billa | last post by:

Hi, I am replaceing a big string using different regular expressions (see some example at the end of the message). The problem is whenever I apply a "replace" it makes a new copy of string and I want to avoid that. My question here is if there is a way to pass either a memory stream or array of "find", "replace" expressions or any other way to avoid multiple copies of a string. Any help will be highly appreciated

Hi, i'm using the regular expression \b\w to find the beginning of a word, in my C# application. If the word is 'public', for example, it works.

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
