RegEx Pattern For Names?

Feb 21, 2012

I 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.

Convert This PHP RegEx Match Pattern To .Net?

Feb 8, 2012

This is a pretty complex regular expression that returns an array of key/value pairs from a proprietary string of data. Here is sample of the data, in case the express can not be used in .Net and another method needs to be used.

0,"101"1,"12345"11,"ABC Company"12,"John Doe"13,"123 Main St"14,""15,"Malvern"16,"PA"17,"19355"19,"UPS"21,"10"22,"GND"23,""24,"082310"25,""26,"0.00"29,"1Z1235550300000645"30," PA 193 9-05"34,"6.55"37,"6.55"38,"8.05"65,"1Z1235550300000645"77,"10"96,""97,""98

If you look closely you see its key,"value",key,"value" The only guarantee on formatting is that each key value pair is separated by a comma, and each value will always be encased in double quotes. The main problem (the reason you cant explode it) is the poor choice of the previous coder to separate keys and values with the same character as the entries. Anyways, out of my hands. Here is a working PHP example.

function parseResponse($response) {
// split response into $key, $value pieces
preg_match_all("/(.*?),"(.*?)"/", $response, $m);

Developing A Regex/pattern Tester In .net?

Aug 18, 2008

I am developing a regex/pattern tester in vb.net where I have three textbox's:

- Textbox1: Here I enter my regular expression for pattern matching in textbox2

- Textbox2: Upload the plain-texts from dB and then look for a match

- Textbox3: Displays the result of the search.

Now the issue I am having is when I enter a regular expression in **Textbox1** and click search it is unable to find any matching pattern even though I have made sure a matching text is present in the paragraph.But whereas, if I enter the non-regex word/text itself in Textbox1 it is able to find a match.

In my button click_event I have initiated all the relavent regex functions etc but still not able to figure out why it wont except regex expressions instead of the word itself.Here is the code I am using for pattern search:

Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Dim m As Match
Dim re As Regex
Dim matches As MatchCollection

RegEx - Finding Pattern In String

Jul 22, 2009

I'm trying to find a pattern in a string, I guess is very easy but I'm terrible in regular expressions. I have a big text and I need to find all the next type of pattern:
{a|b|c}
That can be also something like this: {a|b|c|s|f|f|ft|r} or any number of items inside but at least 2 items so the pipe symbol is another key. Is this an easy regular expression? I'm using vb.net 2005.

RegEx - Pattern For Stuff In Parenthesis

Dec 17, 2009

I have strings like:
1. Three (3) 10,000 gallons underground gasoline storage tanks.
2. Equip ID: (23-1)

I want to extract the '3' and the '23-1' and from the strings. I can rely on the first set being inside ( ) as the strings I need. The strings will be numeric characters plus the dash (anything between ( ) would be preferable.) What RegEx pattern would I use?

Here's what I have so far but it gets the first number and not the ones in ( ):
Function Extract_Stuff(ByVal LineText As String) As String
Dim myMatches As MatchCollection
Dim myRegex As New Regex("([0-9]+)")
myMatches = myRegex.Matches(LineText)
For Each successfulMatch As Match In myMatches
Return successfulMatch.Value ' should only be one match, return first
Next
Return ""
End Function

REGEX And VB: Pattern Assignment Via If Statement?

Jul 15, 2009

I'm trying to assign the pattern regex looks for using an if statement like below. Then I use match to test, returning t/f from match.success. The patterns work fine, and finds what i am looking for in a test data set. The problem comes when I try to assign a pattern to test for via an if statement (assigned to SearchRegexString below) and then try to match using the appropriate object. so basically

SearchRegexString = "TestStringA"Object = new regex (pattern, options)object.match(string).success

[Code]...

doesn't work. match.success always returns false when the if then construct is used even if the phrase exists in the string. Is this a compiler issue, beyond the limits of Regex? what is going on?

VS 2010 Simple Regex Pattern Matching?

Jul 1, 2011

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?)

VS 2010 Proper Regular Expression (Regex) Pattern?

Apr 24, 2012

It seems up until now I've never used Regex, nor even heard of it. But once I did I realized how extremely useful this is. Having said, it's been 2 days since I've began looking into constructing my own patterns. My most recent being for decimals. Is the pattern I provided below "proper"? and are there also any improvements I could be making for a more efficient patter, which would minimize any possibility of a loophole? [code] So for my use, this is doing what it's supposed to being doing under every test I can through at it. But do mind the 0. and .0, I have a function to normalize these as they are proper, I just pad the left and right accordingly. I found most regex questions asked here..and yes I am doing this in vb.net so it fits. If not, then feel free to move this post somewhere else better suited for the topic of discussion.

C# - Regex Pattern That Matches SQL Object (table/function/view)?

Apr 3, 2012

Question:Given a SQL string like

CREATE VIEW TestView AS
SELECT value1, value2
FROM TABLE_0[code]...........

for each strObjectName in tables, to check whether or not the view depends on this object.But this fails on table_12 (and results in cyclic dependencies) for example, because tables contains "table_1". Aaargh.I need a regex that can check if the view definition contains a function name, table-valued function or another view...

(
For checking with
System.Text.RegularExpressions.Regex.IsMatch([code].....

But it fails, plus it doesn't account for object names embraced in brackets, like

Concatenating A Variable With A Regex Group Match In Regex.replace?

Apr 5, 2012

I 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].

[code]...

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?

C# - Decompiling .Net Assembly Produces Code With Invalid Member Variable Names; Names Starting With $STATIC$?

Sep 5, 2011

I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:

private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;

why the generated code has these invalid member variables?
