contains

问题 EDIT : My original question was asking whether anything could ever be faster than regex for matching a whole word. I have added my code, and have run several tests. The details are below My sample matching string (from The Old Man And The Sea ) He was an old man who fished alone in a skiff in the Gulf Stream and he had gone eighty-four days now without taking a fish. In the first forty days a boy had been with him. But after forty days without a fish the boy’s parents had told him that the

问题 Imagine this XML file (sorry for sick example!!) <DOC> <Test> <Name>1 vs 100 Pre pre History</Name> <Type>Dinasors</Type> </Test> <Test> <Name> 1 vs 100 Post moderns</Name> <Type>Aliens</Type> </Test> </Doc> The idea is returning the Type value, By checking if Name node contains a specific character or string. For example I want a XPath Query like: /Doc//Test[contains "Pre" and "History" and 1]/Type That is check if Test contains "Pre" and "History" and number 1, What will be the xpath query?

问题 I have a small example table temp.ty : From this table I want to only extract the rows where ipc is not present in not_ipc (and where exclude is not present in other_classes ), which seems rather straigtforward. Yet the following query returns zero results: SELECT * FROM temp.ty where not ipc contains not_ipc If I repclace not_ipc with for example 'G01N 33' it doesn't work either yet if I replace not_ipc with 'G01N' it works just fine. I have tried variations with wildcards and LIKE

问题 I have an error that I can't seem to figure out. Anyone has an idea what I'm doing wrong here? Please assume that images has place, subject, description, and testing appears several times in subject or place or description. Also, I did set the ConText initialization parameter TEXT_ENABLE to be true. SELECT 4*SCORE(1) + 2*SCORE(2) + SCORE(3) AS RANK FROM images i WHERE CONTAINS(i.subject, 'testing', 1)>0 OR CONTAINS(i.place, 'testing', 2)>0 OR CONTAINS(i.description, 'testing', 3)>0 ORDER BY

问题 The following query: SELECT ARRAY[[1,2,3], [4,5,6], [7,8,9]] @> ARRAY[2, 3, 5]; gets responded with true and not false as expected, since the array[2, 3, 5] doesn't exist in the source array. Any ideas how can it happen? Maybe flatten is applied to multidimensional arrays? 回答1: It's not answer why, but I've tried to find a way to do what you need, best I've got so far is: with cte_arr as ( select ARRAY[[1,2,3], [4,5,6], [7,8,9], [10,11, 12], [2,5,3]] as arr ), cte_s as ( select generate

问题 I'm attempting to select rows from a dataframe using the pandas str.contains() function with a regular expression that contains a variable as shown below. df = pd.DataFrame(["A test Case","Another Testing Case"], columns=list("A")) variable = "test" df[df["A"].str.contains(r'\b' + variable + '\b', regex=True, case=False)] #Returns nothing While the above returns nothing, the following returns the appropriate row as expected df[df["A"].str.contains(r'\btest\b', regex=True, case=False)]

问题 I have a custom object in this project of mine, called Page. A Page's identifying feature is its title. A Page is normally created by calling Wiki.page, Wiki.category, or Wiki.template, or by generating them from other methods like Wiki.random. (I recommend you look a little bit at what that is before going on.) Sometimes, users of this module might want to generate some Pages and convert that generator into a normal list . After they obtain that list of Pages, they might want to check if

问题 I have 2 XML files : file1.xml <data>doe90</data> <data>foo</data> <data>goo</data> ... file2.xml <data2>nan</data2> <data2>goo</data2> <data2>test</data2> ... I stored this data in 2 vars : let $data := //data, $data2 := //data2 And began to do this : for $d in $data2 return if() (: $d is also in $data ? :) What should I do ? Thanks EDIT : Of course I tried contains, but got an error : if(contains($d,$data) = 0) An exception occurred during query execution: XPTY0004: cannot convert 'xs

问题 I've been struggling. How do I write this: /* initialization */ List<Tuple<string, string, string>> mytuple = new List<Tuple<string, string, string>>(); //pseudocode if(mytuple.Contains("hello") in Item2) { Console.Write("Success"); } 回答1: /* initialization */ List<Tuple<string, string, string>> mytuple = new List<Tuple<string, string, string>>(); bool containsHello = mytuple.Any(c=>c.Item2.Contains("hello")); if(containsHello ) { Console.Write("Success"); } 回答2: You can use linq to check it:
