You can use string operators: $ foo=1:2:3:4:5 $ echo ${foo##*:} 5 This trims everything from the front until a ‘:’, greedily. ${foo <– from variable foo ## <– greedy front trim * <– matches anything : <– until the last ‘:’ }
This is actually on the main page of nltk.org: >>> import nltk >>> sentence = “””At eight o’clock on Thursday morning … Arthur didn’t feel very good.””” >>> tokens = nltk.word_tokenize(sentence) >>> tokens [‘At’, ‘eight’, “o’clock”, ‘on’, ‘Thursday’, ‘morning’, ‘Arthur’, ‘did’, “n’t”, ‘feel’, ‘very’, ‘good’, ‘.’]

here is another easier option select to_number(column_value) as IDs from xmltable(‘1,2,3,4,5’);
Yeah, it’s a little convoluted (compared to the good ol’ way), but this should do it: TokenStream tokenStream = analyzer.tokenStream(fieldName, reader); OffsetAttribute offsetAttribute = tokenStream.getAttribute(OffsetAttribute.class); TermAttribute termAttribute = tokenStream.getAttribute(TermAttribute.class); while (tokenStream.incrementToken()) { int startOffset = offsetAttribute.startOffset(); int endOffset = offsetAttribute.endOffset(); String term = termAttribute.term(); } Edit: The new way According to Donotello, TermAttribute has been … Read more
Do it like this: char s[256]; strcpy(s, “one two three”); char* token = strtok(s, ” “); while (token) { printf(“token: %s\n”, token); token = strtok(NULL, ” “); } Note: strtok modifies the string its tokenising, so it cannot be a const char*.
You cannot do that with strtok(); use strtok_r() from POSIX or strtok_s() from Microsoft if they are available, or rethink your design. char *strtok_r(char *restrict s, const char *restrict sep, char **restrict lasts); char *strtok_s(char *strToken, const char *strDelimit, char **context); These two functions are interchangeable. Note that a variant strtok_s() is specified in an … Read more
Joyce, Here are three examples: 1) Using dbms_utility.comma_to_table. This is not a general purpose routine, because the elements should be valid identifiers. With some dirty tricks we can make it work more universal: SQL> declare 2 cn_non_occuring_prefix constant varchar2(4) := ‘zzzz’; 3 mystring varchar2(2000):=’a:sd:dfg:31456:dasd: :sdfsdf’; — just an example 4 l_tablen binary_integer; 5 l_tab dbms_utility.uncl_array; … Read more
Use Reader.read(). A return value of -1 means end of stream; else, cast to char. This code reads character data from a list of file arguments: public class CharacterHandler { //Java 7 source level public static void main(String[] args) throws IOException { // replace this with a known encoding if possible Charset encoding = Charset.defaultCharset(); … Read more
You can use a regular expression to fish out this sort of information. Pattern p = Pattern.compile(“\”([^\”]*)\””); Matcher m = p.matcher(line); while (m.find()) { System.out.println(m.group(1)); } This example assumes that the language of the line being parsed doesn’t support escape sequences for double-quotes within string literals, contain strings that span multiple “lines”, or support other … Read more
