来自主题: Java版 - how to set up multiple delimiter?
dont understand ur question.
if u want the string of ", ??? ." as the delimiter, since it's a string,
i don't see a problem;
if u want multiple delimiters, say ",", "???", ".", at least u can
replace the occurrences of any other delimiters into one same delimiter.

Easy!
Just use infile:
Infile Fileref dlm=", /"
then SAS will treat both of them as delimiters.
Usually, if u use dlm="abc" then SAS regard each letter or any combination
of the 3 letters, a aa bb cc acb bca etc...as a delimiter. However, if you
use dlmstr="abc", then SAS only uses the STRING---abc-- as a delimiter.

印度边防部队在中印边界锡金段越界进入中国领土的事实和中国的立场

1. 洞朗地区位于中国西藏自治区亚东县,西与印度锡
金邦相邻,南与不丹王国相接。1890 年,中国和英国签订《中
英会议藏印条约》,划定了中国西藏地方和锡金之间的边界。
根据该条约规定,洞朗地区位于边界线中国一侧,是无可争
议的中国领土。长期以来,中国边防部队和牧民一直在该地
区开展巡逻和放牧活动。目前,洞朗地区与锡金之间的边界
是中印边界锡金段的一部分。
2. 2017 年 6 月 16 日,中方在洞朗地区进行道路施工。
6 月 18 日,印度边防部队 270 余人携带武器,连同 2 台推土
机,在多卡拉山口越过锡金段边界线 100 多米,进入中国境
内阻挠中方的修路活动,引发局势紧张。印度边防部队越界
人数最多时达到 400 余人,连同 2 台推... 阅读全帖

前总统马英九今天表示,常设仲裁法院认定太平岛是礁不是岛,他非常错愕与愤怒,绝不接受荒谬不公的国际仲裁,他呼吁政府立即提出具体措施,捍卫中华民国的太平岛。
马英九指出,这个法庭的存在,应该是为国际争端定纷息争、避免走上冲突甚至战争。但是,这样的仲裁结果,不但没有排难解纷,反而增加了冲突的可能。「在背後操控的势力,看似赢了面子,其实却输了裡子。」
「菲律宾对中国」南海仲裁案,常设仲裁法院今天公布结果,称中国大陆在9段线范围内主张的历史权利没有法律依据,而南沙群岛的所有海上地物,均为礁岩,包括太平岛在内。
马英九晚间在脸书发文表示,从去年12月到今年5月,包括他在内,150多名部会首长、国内外学者专家和国内外媒体,都访问太平岛,亲眼见证这个淡水充裕(南沙唯一)、农产丰富、生活机能完整的岛屿,完全符合「联合国海洋法公约」第121条关于「岛屿」必须「维持人类生存与自身经济生活」的要件。
他说,至今年4月底为止,也有430篇国际媒体完整陈述「太平岛是岛」的事实。太平岛是「岛」不是「礁」,已是国内外多数人的共识。
马英九指出,70年来,太平岛是在中华民国有效统治之下,对地区提供医疗救难等服务,夙有口... 阅读全帖

南海仲裁案
(菲律宾共和国 v. 中华人民共和国)
海牙,2016年7月12日
仲裁庭发布裁决
今日,根据《联合国海洋法公约》(“《公约》”)附件七组成的仲裁庭就菲律宾共和国
对中华人民共和国提起的仲裁案作出了一致裁决。
该仲裁案涉及在南海的历史性权利的作用和海洋权利的渊源、某些岛礁的地位及其能够
产生的海洋权利,以及菲律宾声称违反了《公约》的中国某些行为的合法性问题。考虑
到《公约》对强制争端解决的限制性规定,仲裁庭强调,它既不对任何涉及陆地领土主
权的问题进行裁决,也不划定当事双方之间的任何边界。
中国反复申明“其不接受、不参与由菲律宾单方面提起的仲裁”。然而,《公约》附件
七规定,“争端一方缺席或不对案件进行辩护,应不妨碍程序的进行”。附件七同时规
定,在争端一方不参与程序的情况下,仲裁庭“必须不但查明对该争端确有管辖权,而
且查明所提要求在事实上和法庭上均确有根据”。因此,在整个程序中,仲裁庭采取了
一些步骤验证菲律宾诉求的正确性,包括要求菲律宾提交进一步的书面论证,在两次庭
审之前及庭审过程中对菲律宾进行询问,指定独立的专家就技术性问题向仲裁庭报告,

这是(author1,2014; author2,2015)

char * strtok( const char * string, const char * delimiters );
Sequentially truncate string if delimiter is found.
第一部分:
If string is not NULL, the function scans string for the first occurrence of
any character included in delimiters. If it is found, the function overwrites
the delimiter in string by a null-character and returns a pointer to the token

来自主题: Unix版 - how to count string times using perl
Using split generally is clean but not robust in this situation. Try "
ABABABAB": it returns 0.
This is because split functions treats the leading and trailing delimiters
differently. It ignores all trailing delimiters while insert an empty string
before the leading delimiter.

python的默认str.split()是比较体贴的,
不论空几格,甚至是制表符,都按一个delimiter处理
In [10]: 'a b'.split()
Out[10]: ['a', 'b']
In [11]: 'a b'.split()
Out[11]: ['a', 'b']
In [13]: 'a b\tc'.split()
Out[13]: ['a', 'b', 'c']
楼主要区分空一格还是空两格,那么指定delimiter即可
In [12]: 'a b'.split(' ')
Out[12]: ['a', '', '', '', '', '', '', 'b']

string extractPartialString(const string& whole, int start, int end);
就是要找到在[start, end)之间的数字组成的子串。比如extractPartialString(input
, 2, 5)应该返回子串"-54,65,367"。我就是直接一个一个的按照分隔符","来找,找到
指定个数以后就返回,但是这样如果start很靠后的话会需要很长时间,毕竟要O(L+M)
的时间。不知道有没有什么更优化的算法可以实现这样的功能?请各位大牛支招,多谢!
以下是我目前的实现代码:
#include
#include
using namespace std;
/**

\left和\right是用来自动调整delimiter大小的,后边跟点表示不需要delimiter

如果是因为数字后面有多余的空格,或许可以用"text to column" ,delimited, 然后
选"space" 做delimiter 试试看。
