YARPQ - Yet Another Regex Pattern Question:
What I am trying to figure out is how to use a custom delimiter, single character or set of characters, to wrap a block of text inside a larger body of text and then pull that text out via regex. I have successfully done this with a single instance of wrapped text. If I have multiple instances, it blows up. Here is an example.
This would be my text block with the internally wrapped text:
[Code]....
When my current regex runs on this block, the greedy nature gives me a match starting with my first wrapped block delimeter and ending with my second wrapped block end delimeter. So my regex of @"#Delim(.*)#EndDelim" doesn't work in this instance. I am trying to figure out how to exclude the #EndDelim from my grouping. Simply using ([^#EndDelim]*) doesn't work as it tells regex to ignore the individual characters inside the brackets and not the actual word so this breaks if I have any of those characters inside my wrapped block of text.
I am probably making this harder than it needs to be. Does anyone know of a good solution or how to ignore entire words in regex?
I will have the following possible strings:
12_3
or
12_3+14_1+16_3-400_2
The numbers could be different, but what I'm looking for are the X_X numeric patterns. However, I need to do a replace that will search for 2_3 and NOT return the 12_3 as a valid match.
The +/-'s are arthemtic symbols, and can be any valid value. They also ARENT required (in the example of the first) .. so, I might want to check a string that just has 12_3, and if I pass in 2_3, it would NOT return a match. Only if I passed in 12_3.
This is for a C# script.
I want regex pattern for phone number as follow.

I wonder what the Regex pattern for session id is?
I'm trying to build an asp.net page using c# that will query a column in an Oracle database that has 20,000 rows. I want to display all rows that match this regular expression pattern "[]$".(should only have about 5 rows that match this pattern) The version of Oracle we use does not support regex so I need to find a way to do this in c# but I'm not sure how do that.
View 2 RepliesI have a table Books with columns BookID, BookSummary, BookAuthor.
What I have stupidly done was to add a link to another url at the end of the BookSummary. Assuming the text is something like this:
This is a book about a love story in World War 2 in Europe. The book is written by Elliot James.
I have added
<a href='http=://XXXXXX'>Buy Book</a> at the end of the text making the final content of BookSummary to be like:
This is a book about a love story in World War 2 in Europe. The book is written by Elliot James.
<a href='http=://XXXXXX'>Buy Book</a>
I now need to write a code (via regex?) to read through each BookSummary, find the <a href='http://XXXXX'>Buy Book</a> and delete it. But the problem is the content in XXX could be anything and I cannot use typical string functions. Can anyone guide me to
achieve this using Regex?
What's the regular expression to check if a string starts with "mailto" or "ftp" or "joe" or...
Now I am using C# and code like this in a big if with many ors:
String.StartsWith("mailto:")

It looks like a regex would be better for this. Or is there a C# way I am missing here?

View 2 RepliesI have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
Now user wants that if the text box is clear, the GridView disappear.
I can only find TextBox1_OnTextChanged. But I want to have that while the user is clearing the text, if the length of text becomes zero, the GridView is clear out. So I am looking for OnTextChanging(). Well of course this function does not exist. How to achieve the same purpose?
I have a web application (done in ASP/C#) that has regex validation on a text box. Initially the regex works perfectly fine. But then I also provide a button click event (clear) that allows the user the clear text box and change their input for a new query. At this point (page post back) the regex takes control and maintains control of the text box so a new query can't be run. Can anyone tell me what to do so that the regex doesn't fire on page postback and allows new input for validation?

I have a PDF document with a number of text fields, several of which have a maximum length - namely, a maximum number of allowable characters. Is there a way using iTextSharp to determine this setting? Here's the code I have so far:
Dim reader As New iTextSharp.text.pdf.PdfReader("Foobar.pdf")
Dim inputFields As IDictionary(Of String, iTextSharp.text.pdf.AcroFields.Item) = reader.AcroFields.Fields
For Each key As String In inputFields.Keys
Dim PDFFieldName As String = key
Dim MaxFieldLength As Integer = ???
...

I need to set MaxFieldLength to the number of allowable characters for the current form field being iterated over.

Is this possible using a regular expression?

View 2 RepliesI have a table being brought in using HttpWebRequest (screen scraping). The table I grab is formatting properly but I have noticed a situation. This table has a URL which refers to a physical web page. What I would like to do is to take that URL using a .Replace clause and thereby change the URL to reflect <a href="details.aspx?id=111"> as opposed to <a href="111.htm">. So I went ahead and tried doing it this way but it doesn't do any replacement.

I figured using the regex expression it would find it and then I could just reuse it.
I was wondering if people out there test the length of their text values before inserting them into an SQL INSERT or UPDATE command? I got lazy and stopped doing it lately but I do restrict the length of some of my character fields so that I have a NCHAR(50) field but don't test the length of the string when inserting or updating and just rely on the server to fire back any problems.Am I being 'efficient' or 'lazy' or even 'dangerous'?I appreciate the opinion of you as just about anyone has more experience with SQL Server than I do.
