UPDATE: With the addition of InExpression in EF6, the performance of processing Enumerable.Contains improved dramatically. The approach described in this answer is no longer necessary. You are right that most of the time is spent processing the translation of the query. EF’s provider model doesn’t currently include an expression that represents an IN clause, therefore … Read more
select=”//*[contains(@address,’Downing’)]”
You can use the text method and pass a function that returns the modified text, using the native String.prototype.replace method to perform the replacement: $(“.text_div”).text(function () { return $(this).text().replace(“contains”, “hello everyone”); }); Here’s a working example.
This is what i’m using in a current project, haven’t had any problems. See if you have better luck with this format: jQuery.expr[‘:’].Contains = function(a, i, m) { return jQuery(a).text().toUpperCase().indexOf(m[3].toUpperCase()) >= 0; }; In jQuery 1.8 the API for this changed, the jQuery 1.8+ version of this would be: jQuery.expr[“:”].Contains = jQuery.expr.createPseudo(function(arg) { return function( … Read more
XPath queries are case sensitive. Having looked at your example (which, by the way, is awesome, nobody seems to provide examples anymore!), I can get the result you want just by changing “business”, to “Business” //production[not(contains(category,’Business’))] I have tested this by opening the XML file in Chrome, and using the Developer tools to execute that … Read more
spoulson has it nearly right, but you need to create a List<string> from string[] first. Actually a List<int> would be better if uid is also int. List<T> supports Contains(). Doing uid.ToString().Contains(string[]) would imply that the uid as a string contains all of the values of the array as a substring??? Even if you did write … Read more
You could simply use ArrayUtils.contains from Apache Commons Lang library. public boolean contains(final int[] array, final int key) { return ArrayUtils.contains(array, key); }
If you are using .NET 3.5 or newer you can use LINQ extension methods to achieve a “contains” check with the Any extension method: if(CartProducts.Any(prod => prod.ID == p.ID)) This will check for the existence of a product within CartProducts which has an ID matching the ID of p. You can put any boolean expression … Read more
You can use javascript’s indexOf function. var str1 = “ABCDEFGHIJKLMNOP”; var str2 = “DEFG”; if(str1.indexOf(str2) != -1){ console.log(str2 + ” found”); }
If you have a list and you want to know where within the list an element exists that matches a given criteria, you can use the FindIndex instance method. Such as int index = list.FindIndex(f => f.Bar == 17); Where f => f.Bar == 17 is a predicate with the matching criteria. In your case … Read more
