tokenize

问题 I have this lines of text the number of quotes could change like: Here just one "comillas" But I also could have more "mas" values in "comillas" and that "is" the "trick" I was thinking in a method that return "a" list of "words" that "are" between "comillas" How I obtain the data between the quotes? The result should be: comillas mas, comillas, trick a, words, are, comillas 回答1: You can use a regular expression to fish out this sort of information. Pattern p = Pattern.compile("\"([^\"]*)\"")

问题 I want to be able to split csv strings in Oracle 9i I've read the following article http://www.oappssurd.com/2009/03/string-split-in-oracle.html But I didn't understand how to make this work. Here are some of my questions pertaining to it Would this work in Oracle 9i, if not, why not? Is there a better way of going about splitting csv strings then the solution presented above? Do I need to create a new type? If so, do I need specific privilages for that? Can I declare the type w/in the

问题 I am writing a program that takes a file of ordered pairs of numbers as it's input, and I want to split those ordered pairs and convert them to an integer for storage in an array. The file could be like this: 0 1 1 4 9 11 12 45 I want to write a function that takes in the line, (assumed to be already null terminated in another part of the program), splits the numbers at the space and then stores them in a integer array of size two: int *store = malloc(2 * sizeof(store)); I have looked into

问题 I have the following string : s = "server ('m1.labs.terada')ta.com') username ('user5') password('use r5') dbname ('default')"; I have defined a regex for extracting the values between the paranthesis,i.e m1.labs.terada')ta.com , user5. regex re("\(\'[!-~]+\'\)"); sregex_token_iterator i(s.begin(), s.end(), re, 1); sregex_token_iterator j; However, I am not able to extract 'use r5'. Is there any way I can modify the regex to include white spaces as well? 来源： https://stackoverflow.com

问题 If I have a file with some structure to it: type 2 0 0 name 100 100 name 1 1 2 name name How can I use a StreamTokenizer to process this file? Is the only way the procedural approach? i.e. StreamTokenizer st = new StreamTokenizer(new FileReader(filename)); if (st.nextToken() != StreamTokenizer.TT_EOF) { st.nextToken(); if (st.sval == "typea") { st.nextToken(); int i = (int) st.nval; if (i > 0) { while (i > 0) { // process node sets } } } else if (st.sval == "typeb") { st.nextToken(); int i =

问题 I have a value like this: Supoose I have a string: s = "server ('m1.labs.teradata.com') username ('u\'se)r_*5') password('uer 5') dbname ('default')"; I need to extract token1 : 'm1.labs.teradata.com' token2 : 'u\'se)r_*5' token3 : 'uer 5' I am using the following regex in cpp: regex re("(\'[!-~]+\')"); sregex_token_iterator i(s.begin(), s.end(), re, 0); sregex_token_iterator j; unsigned count = 0; while(i != j) { cout << "the token is"<<" "<<*i++<< endl; count++; } cout << "There were " <<

问题 So if I have the following char array in C: "a b c" // where "a", "b", and "c" can be char arrays of any length and the // space between them can be of any length How can I remove the "a" token but store the rest "b c" in an char pointer? So far I have implemented the following method that doesn't work: char* removeAFromABC(char* a, char* abc) { char* abcWithoutA[MAXIMUM_LINE_LENGTH + 1]; int numberOfCharsInA = strlen(a); strcpy(abcWithoutA, (abc + numberOfCharsInA)); return abcWithoutA; }

问题 I am rather new to SolR. I would like to use multiple tokenizers. I am using the standard tokenizer so that words get split via \t, space, comma, etc. Now I would like to use an additional tokenizer. If there is the word "cowshed" I would like it to become "cow" and "shed". There are only I few words which are common to the search index which I would like to split. Therefore I planned using the regex tokenizer. However I get an error message when I try to ("multiple tokenizers at xml root").

问题 In Oracle I've created a data type: TABLE of VARCHAR2(200) I want to have a variable of this type within a Stored Procedure (defined locally, not as an actual table in the DB) and fill it with data. Some online samples show how I'd use my type if it was filled and passed as a parameter to the stored procedure: SELECT column_value currVal FROM table(pMyPassedParameter) However what I want is to fill it during the PL/SQL code itself, with INSERT statements. Anyone knows the syntax of this? EDIT

问题 I have few questions about my assignment. The assignment is to let user enter a sentence, and the program counts each word's frequency, when user enters an empty string, quit the program. Also, the program is case sensitive. For example, Apple is an apple is a phone , the result is that Apple-1; is-2; an-1; a-1; phone-1 . Here is my code: public static void main(String[] args) { while (true) { System.out.println("Enter a sentence:"); Scanner keyboard = new Scanner(System.in); String sentence
