Using regular expression in query

Hi all,

I need to filter out rows like 'A <number>'
where the second character=space character.

To start with I have the expression: ~* '^A' which will
filter out any row starting with 'A'.
Now there must be something to indicate the space character.
(in Perl '\s' defines <space> but not in Postgres it seems)

Grateful for any help on this!

I'm trying to use a regular expression to match a hidden html tag and replace it with the results of a mysql query. The query is based off a part of the hidden tag. For example: The article looks like this ("Math" is the value I want to pass to my function call, it could be any value for the department name): $article = "Below is a listing of the staff in our Math department:<p><!-- Directory:Math -->"; I'm using this preg_replace...

I have a regular expression that allows only certain characters to be valid in an xml doc as follows: <xs:pattern value="^*" /> What I want to do is also allow any unicode character that is enclosed in single quotes to also be valid, no matter where they appear. I tried the following: <xs:pattern value="^*('*)*" />

Hi All, I've got a textbox where I want to make sure the person has entered at least 3 characters before submitting (it's like a partial name lookup type of query), so I don't want them to just enter "a" or "e" in the box and bring back everyone with an "a" or "e" in their name. I figure that a regular expression validation is the way to go, and I tried this: ValidationExpression="^({3,255})$"

Hello all, could not find a regular expression forum, so I thought I would post it to my favorite of the forums. I have a series of applications I've developed which all use a centralized function that creates a connection object and executes an SQL query, i.e. function Query(). I always sanitize my SQL statements to buffer all apostrophes with two apostrophes ala function Buffer(). However, I have long wondered if I could do away with...

I need to create a regular expression that will match a 5 digit number, a space and then anything up to but not including the next closing html tag. Here is an example: <startTag>55555 any text</aClosingTag> I need a Regex that will get all of the text between the html tags above (the html tags are random and i do not know them before hand). The match string always starts with at least 5 digits.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
