contains

问题 This is my situation: I have a string representing a text string myText = "Text to analyze for words, bar, foo"; And a list of words to search for in it List<string> words = new List<string> {"foo", "bar", "xyz"}; I'd want to know the most efficient method, if exists, to get the list of the words contained in the text, something like that: List<string> matches = myText.findWords(words) 回答1: There is no special analysis in this query except you have to use Contains method. So you may try this:

问题 I'm using stack in my program but I have a problem when program is trying to check what element contains in stack. I'm using array of integer in Stack. Short example is: Stack<int[]> myStack = new Stack<int[]>(); myStack.push(new int[]{1,2}); myStack.push(new int[]{1,3}); myStack.push(new int[]{1,4}); if (myStack.contains(new int[]{1,3})) { System.out.println("YES"); } else { System.out.println("NO"); } Now it was printed "NO". How could I do to get "YES" ? I know that the problem is that I'm

问题 I want to check an array is subset of another array. The program prints false, but I expect true. Why isn't containsAll returning true? int[] subset; subset = new int[3]; subset[0]=10; subset[1]=20; subset[2]=30; int[] superset; superset = new int[5]; superset[0]=10; superset[1]=20; superset[2]=30; superset[3]=40; superset[4]=60; HashSet sublist = new HashSet(Arrays.asList(subset)); HashSet suplist = new HashSet(Arrays.asList(superset)); boolean isSubset = sublist.containsAll(Arrays.asList

问题 I have a text file and would like to check if it contains a string. The text file is stored in a char array: char buffer[512][128]; . Q1: Is it easier if I buffer it in one long array instead of a multidimensional array? Q2: How could I check whether the buffer contains the string char *s1 = "Hello world!"; ? I will need to search for multiple strings. 回答1: It will be much easier to use a single 1D array. strstr(buffer, s1) != null (once you've changed buffer into a 1D array) 回答2: strstr 来源：

问题 I'm trying to parse a piece of XML and remove nodes that contain certain values. I know how to remove them if the value is exact, but I want to use something like a "contains". This works to delete exactly: update @XML set data.modify('delete //Message[text() = "customer has deleted their account"]') But I want to delete where the "Message" node just contains the text, something like: update @XML set data.modify('delete //Message[contains(text(), "customer")]') However this returns the error:

问题 How do I use the Python in operator to check my list/tuple sltn contains each of the integers 0, 1, and 2? I tried the following, why are they both wrong: # Approach 1 if ("0","1","2") in sltn: kwd1 = True # Approach 2 if any(item in sltn for item in ("0", "1", "2")): kwd1 = True Update: why did I have to convert ("0", "1", "2") into either the tuple (1, 2, 3) ? or the list [1, 2, 3] ? 回答1: if ("0","1","2") in sltn You are trying to check whether the sltn list contains the tuple ("0","1","2")

问题 I have the following WHERE clause: WHERE (@Keywords IS NULL OR (CONTAINS((p.Title, p.Area, p.[Message]), @Keywords)) ) If @Keywords = 'control' , then the query executes successfully and filters my records If @Keywords = 'control of' , then I get the following error: Syntax error near 'of' in the full-text search condition 'control of'. Why is this and what can I do to resolve the issue? The main reason I'm using this method over using LIKE condition is so that I can search multiple words.

问题 In my swift app I have a structure: open class MyStruct : NSObject { open var coordinate = CLLocationCoordinate2D(latitude: 0, longitude: 0) open var username: String? = "" open var id: String? = "" } And I create an Array of it: var array:[MyStruct] = [] Then I'm creating an object: let pinOne = MyStruct() pinOne.coordinate = CLLocationCoordinate2D(latitude: request.latitude, longitude: request.longitude) pinOne.username = request.username pinOne.id = request.id and I want to add it to the

问题 I have an ArrayList in Java which is made up of a type containing two strings and an integer. I can successfully test if one element of this ArrayList equals another but I find that the contains method fails. I believe this is due to the fact that my type is not primitive. Now I see two alternatives to this and I wonder which is the best option: To implement my own contains method by iterating through the ArrayList and testing equality of each element against the one I'm looking for and then

问题 i am trying to use my keyboard to click on a button using the id. For some buttons i had to set the ID, which actually works. But as soon as i try to use the keyboard for the buttons where i set the id, it won't work. I am not getting any errors and since adding the id to the element works, i am kinda confused why i cannot use the new set id later in the code. //setting id for first button (works) $( "a:contains('Im Verband freigeben')" ).attr('id', 'freigabe-verband'); //setting id for
