【转】XML中关于DTD类型(内部(SYSTEM)的和外部(PUBLIC)的区别)

[亡魂溺海] 提交于 2020-03-02 05:00:01
DTD是什么?Document Type Definition——文档类型定义。 在做自定义标签的时候,写标签库定义文件tld时,要写一大段东东:<!DOCTYPE ...... >。当时只知道拷贝、粘贴,也没有去想这是什么东西。今天才知道,这玩意儿叫DTD。是为了规范xml文档元素编写的。 DTD的语法规定,DTD的所有关键字都是大写的,如DOCTYPE,ELEMENT等,它分为两种。 1、内部DTD。注意的是在元素名后面一定要有空格,否则就不是格式良好的 <!DOCTYPE 根元素名 [ <!ELEMENT 元素名 (元素类型定义)> ]> 如对下面这个xml文档的类型定义: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE poem [ <!ELEMENT poem (title,author,line+)> <!ELEMENT title (#PCDATA)> <!ELEMENT author (#PCDATA)> <!ELEMENT line (#PCDATA)> ]> <poem> <title>静夜思</title> <author>李白</author> <line>床前明月光,</line> <line>疑事地上霜.</line> <line>举头望明月,</line> <line

How to search for public datasets on BigQuery?

走远了吗. 提交于 2020-01-25 02:56:25
问题 Is there a way to search for public datasets on BigQuery? Related question about viewing datasets listed by default here. There is no way to search for public datasets which are not listed in the BQ GUI under 'bigquery-public-data' as mentioned here: https://stackoverflow.com/a/14969215. There is an older Reddit post listing many of the ones listed in the GUI here. There seems to be a separate list under fh-bigquery as seen here for a freebase dataset. What is this fh-bigquery designation?

Public and Internal members in an Internal class?

我的未来我决定 提交于 2020-01-20 18:21:08
问题 Ok, so this may be a bit of a silly question, and there's certainly the obvious answer, but I was curious if I've missed any subtleties here. Is there any difference in terms of visibility/usability between a public member declared in an internal class and an internal member declared in an internal class? i.e. between internal class Foo { public void Bar() { } } and internal class Foo { internal void Bar() { } } If you declared the method as public and also virtual , and then overrode it in a

public interface member in c#8

限于喜欢 提交于 2020-01-15 03:10:51
问题 Since the latest version of c#, it is possible to write the following interface: public interface IMyInterface { public void MyMethod(); } This seems like a code smell to me, as I feel like the intention was to write the previously available: public interface IMyInterface { void MyMethod(); } Are those two interfaces exactly the same ? Does the public keyword add/changes anything ? Is this something that should be corrected, or am I wrong and should public be consistently used now ? 回答1:

Java never declares access level of variables in methods whether static or not [closed]

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . Today I suddenly realized that Java never specifies access level for local variables when I try to declare a variable for main method. I also tried to give it a access level modifier, but it doesn't compile. The
