Don’t use Regex to parse html. A correct way would be using an html parser like HmlAgilityPack var doc = new HtmlAgilityPack.HtmlDocument(); doc.LoadHtml(htmlstring); var links = doc.DocumentNode.SelectNodes(“//a”) .Select(a => a.Attributes[“href”].Value) .ToList(); solved Regular Expression to find out tag and get the value of HREF using C# [duplicate]

The simplest solution is to split the string into a collection of string then sort that collection and concatenate the result into a string again: you can use a custom comparator using the size of the string and feed it to std::stable_sort with the collection of strings to sort: // Your original string std::string your_string … Read more

In this article, we will discuss some of the common causes of compilation errors and how to fix them. We will also provide some tips and tricks to help you debug your code and get it … Read more
That’s because allLogs is lazy in nature — it will actually hit the database when first enumerated through in the foreach (see “Deferred query execution” here). If you materialize the collection before hand like the following, you will see that it steps through the foreach quickly: db.StatusLogs .Where(sl => sl.ID.Value.Equals(foo)) .GroupBy(sl=>sl.bar) .ToList(); // <– pull … Read more

It depends on the return value of the function. If this is void the function does not have a return value and you do the first. callOne(1, 2); If it has something else like int, char or std::string you can use the first but also the second. callTwo = func2(5, 9); In this case you … Read more
Just use the python datetime module: import datetime dayOfWeek = datetime.datetime(y, m, d).weekday() dayOfWeek will then be an integer between 0 and 6 corresponding to Monday – Sunday. Have a look at the docs for more details. solved Can anyone translate this into python? [closed]
If you can use List<int> instead of array it makes things easier to code and probably cleaner depending on who you ask. let say you change this : int[] array = new int[10] {g1,g2,g3,g4,g5,g6,g7,g8,g9,g10}; Into a list like this : List<int> values = new List<int>(){g1,g2,g3,g4,g5,g6,g7,g8,g9,g10}; An aggregate will test each elements until the list has … Read more

How should we call a function just once from a function which is called ‘n’ no. of times from the main function without using static variable?

When the realloc function can’t get more memory to expand the block to the size you asked for. This is either because there is literally no memory available, or the virtual space is exhausted (e.g. a 32-bit application on a 64-bit machine with 16GB of RAM still can’t use more than 4GB in the process … Read more
