The Regex class represents a regular expression that is not mutable (read-only). It also contains a variety of static methods that allow you to use other regular expression classes without explicitly creating instances of other classes.
Overview of Regular Expression basics
What is a regular expression
When writing a handler for a string, there is often a need to find strings that meet certain complex rules. Regular expressions are the tools used t

IamlaosongWhen using VBA to process Excel files, the key fields of the column number programming is often not known, need to pass parameter settings to know, therefore, when we program, we can not use such a statement to take the number of valid rows:Lineno = [B65536]. End (Xlup). RowThe column name "B" in the above statement, if it is a variable, can be implemented in the form of a string connection, namely:pos_ems = "C"Lineno = Range (pos_ems "6553
IamlaosongWhen the Excel file is processed with VBA, the column number of the keyword segment is often not known when programming. Need to know by the number of parameters, so. When we program, we cannot use this statement to take a valid number of rows:Lineno = [B65536]. End (Xlup). Row ' find valid rows from bottom to topThe column name "B" in the above statement is assumed to be a variable. Can be implemented in the form of a string connection, nam
IamlaosongLooking at a simple loop program, after VBA reads the data from the database, you need to enter a summation formula in the last cell:The formula means cells (i, 9) = Cells (I, 6) + cells (i,7) +cells (I, 8), where rc[-3] represents the formula in the same row The first 3 columns of the cell.How do I represent the first 3 rows in the same column? Very simple, with r[-3]c on it. And so on, the same row after three columns is rc[3], the curre

Static and instance methods

Example
1. Use regular expressions to check repeated words in a string
2. Use a regular expression to check whether the string represents a currency value or whether it has a correct format that represents a currency value
3. Extract re

Boost is a complement to STL, a regex is one of the modules. There are a lot of methods, this article records the common methods.
Introducing Header Files
1. Regex_match
Regex reg ("\\d{3}");
String str = "123";
BOOL B = Regex_match (Str,reg);
2.regex_replace (string s, regex e, string t) replaces the substring in s that matches E with T
After a long break, Eric is back, and continue his awesome RegEx 101 exercise series, in this exercise, the question Eric asks is:
Bytes -------------------------------------------------------------------------------------------------
Given a string like:

Count how many numbers there are in this string

Like 415.555.4242 or (415) 555-4242 Such a phone number format, how to check? If the phone number has an extension, such as 415-555-4242 x99, how to check? So the Isphonenumber () function fails at the time of validation.2 regular expressions, referred to as regex, are the descrip

Although the release of the new open C/C ++ SDK supports libraries such as stlport and boost, the boost support is incomplete. The RegEx library was initially tested earlier, and many errors were prompted during compilation. The test example can be run after the test is completed. The specific process is described below:

RegEx
Getting started (1)
Regular Expressions usually have a lot of contact, but most of them are in the form of casual flowers. If you want to search, you will forget to read it. Today, I reviewed the results and wrote them out to my summary:
The following is a simple usage. The complexity will continue tomorrow:
LRegEx. ismatchUsage
//Simply match a word
Console. writeline (
"
\ N \ nismatch Demo:
"
);
The namespace using system. Text. regularexpressions needs to be introduced. (If this parameter is not introduced, system. Text. regularexpressions. RegEx must be written when RegEx is written)
Replace method of Regular Expression
String T = "sdf1234sdf12sd12 ";T = system. Text. regularexpressions. RegEx. Replace (T, @ "/d + [A-Za-Z] + ","");
@ "/D + [A-Z] + | [A
, all with built-in support for regular expressions, but not in C ++. The C ++ standard is also silenced when it comes to regular expressions. Boost. regEx is a perfect and effective library. It incorporates regular expressions into C ++ programs and contains several different syntaxes used by common tools such as Perl, grep, and Emacs. It is one of the most famous Regular Expression Libraries in C ++, which is easy to use and extremely powerful.
How
Today I think of this problem again, and I feel it is necessary to record it. On the one hand, it took me more than half a year, and I also claim that the popular Regex engine should have swept into the history garbage, but in the end, at least I did not really achieve this goal. On the other hand, this is a time-consuming task, and we can't go into any further time.
Therefore, the best way is to review old things and sort out ideas first. If there is
