View 2 RepliesCan't Find Correct Pattern For Regex?
Mar 3, 2012I need your help to find the right pattern to extract a string that i need.. The problem is that i have to extract all there is between this caracters:<a href="/url?q=(text to extract whatever it is)& I tried this pattern, but it's not working for me! : /(?<=url\?q=).*?(?=&)/
i'm programming in Vb.net, this is the code, but i think that the problem is that the pattern is wrong:
Dim matches As MatchCollection
matches = regex.Matches(TextBox1.Text)
For Each Match As Match In matches
listbox1.items.add(Match.Value)

.net - What Is This Pattern Called
Sep 8, 2009Private someSub()
If someBoolean = True Then Exit Sub
' do some great work because someBoolean is False
End Sub
I know there is a name for this. The idea is to check something and if it isn't what you want then you stop code processing. I thought it was called "escape pattern", but Google isn't confirming that name.

View 19 RepliesRegEx Pattern For Names?
Feb 21, 2012I was considering validating some input using RegEx to match a pattern of
Firstname, Lastname
I largely have it, but there is so much variability in names that I'm not quite sure if any pattern is safe. In fact, in this case, I know that no pattern is safe, so I have built in a means for the user to accept whatever was entered, regardless of what it was, which isn't so great.
What I'm wondering is whether or not there is a safe Regex pattern that will cover names in this format, or will cover at least most of them. What I currently have is:
"^[A-Z][a-z]+, [A-Z][a-z]+"
But that will allow through things like Hiker, Shaggy, the, which is fairly silly, but shouldn't be allowed....I think. Does anybody use names with commas in them? I know that apostrophes are fairly common, though I'm pretty sure I can ignore them.
