问题 How do namespaces work in Chicken Scheme? I am now using the parley egg, and when I define a function with the name e.g. read , that causes an error because of name clashing (actually, because my read overwrites parley 's own read , and it is invoked with wrong type. Here's the code: (use parley) (define (read p) p) ; This `read` function conflicts. (let loop ((l (parley "> "))) (if (or (eof-object? l) (equal? l "quit")) (print "bye!") (begin (printf "you typed: ~s~%" l) (loop (parley "> ")))

问题 Somewhat of an academic question, but I ran into this while writing some unit tests. My unit test framework (UnitTest++) allows you to create structs to serve as fixtures. Usually these are customized to the tests in the file, so I put them at the top of my unit test file. //Tests1.cpp struct MyFixture { MyFixture() { ... do some setup things ...} }; TEST_FIXTURE(MyFixture, SomeTest) { ... } //Tests2.cpp struct MyFixture { MyFixture() { ... do some other setup things, different from Tests1}};

问题 I'm given a xsd generated C# POCO object that I need to convert to xml. The expected payload however doesn't match the xsds I was given. Specifically, I need to omit the declaration and remove all namespaces from the xml object so that the company in question accepts the API request. Problem Given an object of type T, I want to serialize it without declaration and namespace. I've gotten rid of most of it but q1 has been added to each element for some reason. How do I remove that? Attempt

问题 Can someone explain me what exactly namespaces (xmlns="...") in XML are for and how they have to be used in navigating an XML using E4X (..preferrably in ActionScript 3)? I fail to fully understand their purpose and usage. 回答1: In theory, XML namespaces are used to avoid conflict with tag names. So I can create a namespace that contains a tag named "mytag" and someone else creates a different namespace with the same tag "mytag" and there won't be any conflict. Each "mytag" tag will be clearly
