namespaces

问题 I have written a package for converting XMLs to ePubs. Everything works fine, except some cases, where blank namespace ( xmlns="" ) nodes are being written to the result-documents. Prior to transformation, I prepared temporary variables for holding main-segments(i.e., meta , body etc.) and finally copied the nodes(using xsl:copy-of[@copy-namespaces='no'] instruction) to result-document. I also have used @exclude-result-prefixes='ns_list_sep_by_space' within xsl:transform element and still not

问题 Im getting slightly confused by a C# error. Type t = thing.GetType() t is now a type. but if i attempt to do this: new GenericThing<t> I get a warning saying type or namespace expected. What am i missing? 回答1: t is a Type object created at runtime. Generics expect a type name, resolved at compile time. To create a generic at runtime, you have to use MakeGenericType For example: Activator.CreateInstance(typeof(GenericThing<>).MakeGenericType(t)); 回答2: t is an object instance of type Type , i.e

问题 I stumbled upon a rather exotic c++ namespace problem: condensed example: extern "C" { void solve(lprec * lp); } class A { public: lprec * lp; void solve(int foo); } void A::solve(int foo) { solve(lp); } I want to call the c function solve in my C++ member function A::solve. The compiler is not happy with my intent: error C2664: 'lp_solve_ilp::solve' : cannot convert parameter 1 from 'lprec *' to 'int' Is there something I can prefix the solve function with? C::solve does not work 回答1: To

问题 Let's imagine situation: #include <iostream> int d =34; namespace { int d =45; } int main() { std::cout << ::d ; return 0; } Here the output is 34, because :: means global namespace. But If I comment 3rd line the output is 45, which is strange . If I use std::cout << d ; - I get error s.cxx:12:15: error: reference to ‘d’ is ambiguous How can I access unnamed_namespace::d in this scenario? PS: I've read that unnamed namespace is used for static global variables aka visible only in file scope

问题 I've been getting into Ruby over the past few months, but one thing that I haven't figured out yet is what the Ruby equivalent of C#'s (and other languages) using statement is. I have been using the require statement to declare my dependencies on Gems, but I am getting lazy and would prefer to not fully qualify my frequently used class names with their module (namespace) name. Surely this is possible, right? I must not be using the right terminology as Google hasn't given me anything useful.

问题 I have an xml file with default namespace specified with and without namespace prefix. When I generate xml output I'm getting all xml elements prefixed. Is there way to get rid of the prefixes since I'm using the default namespace? class Program { static void Main(string[] args) { var xml = "<root xmlns='default-namespace' xmlns:key='default-namespace'>" + " <node1></node1>" + " <node2></node2>" + "</root>"; var document = XDocument.Parse(xml); var output = document.ToString(); } } The output

问题 I'm running a for loop inside a function which is creating instances of a class to test them. instead of making new classes it appears to be reusing the same two over and over. Is there something I'm missing about how classes and variables are handled in python methods? how can I generate a new object for each iteration of the loop class CollectionSetImages(unittest.TestCase): def test_keywordset(self): """Testing keyword queries by images equality """ for keyword in ['a','b','c','d','e','f',

问题 I've created a web service using Visual Studio ( 2005 - I know I'm old school ) and it all compiles fine but when it opens I get warned thus: This web service does not conform to WS-I Basic Profile v1.1. And furthermore: This web service is using http://tempuri.org/ as its default namespace. Which would be fine except my service begins thus: [WebService(Namespace = "http://totally-not-default-uri.com/servicename")] Searching the entire solution folder for "tempuri" returns nothing. I can't

问题 I want to use Perl6 Modules to group some functions, i often use. Because this functions are all loosely coupled, I don't like to add them in a class. I like the idea of use , where you can select, which functions should be imported, but I don't like it, that the functions, which are imported are then stored in the global namespace. For example if I have a file my_util.pm6 : #content of my_util.pm6 unit module my_util; our sub greet($who) is export(:greet) { say $who; } sub greet2($who) is

问题 This morning, I've been notified that a new Twig_Extensions release is available! Yay! Before integrating it to twigfiddle, I wanted to see changes. This is mainly adding support to namespaces using class_alias function, and then add PSR-4 correspoding classes that just include the legacy one. But each new (namespaced) classes are implemented like this: <?php namespace Twig\Extensions; require __DIR__.'/../lib/Twig/Extensions/Extension/Text.php'; if (\false) { class TextExtension extends
