parsing

问题 PREFACE: I am asking this question because for some reason I can not get my code to compile. I just want to know whether an incorrect understanding of spirit::x3 is the cause or not Hello, I'd just like to verify something; is the following the correct way (at least technically) of defining rules for a large set of heavily recursive parsers? So for each parser, I do the following operations: // This is for reference only, it greatly simplifies the process of defining attributes. template

问题 I want to parse the following string (using Javascript): color(alias(sumSeries(sys.mem.free.*),"memory (free)"),"#00AA88") into an array of function names and arguments: [["color", "#00AA88"], ["alias", "memory (free)"], ["sumSeries", ""]] plus extract the innermost string sys.mem.free.* The string is actually the target parameter from graphite. I don't want to write a parser myself (dealing with things like double quotes and brackets is hard to get right). Is there a library which helps with

问题 I currently have a bunch of times in a column written like "27:32:18", meaning someone was waiting for 27 hours, 32 minutes, and 18 seconds. I keep getting "ValueError: hour must be in 0..23" whenever I try to parse these values. How should I go about parsing those values or converting them to a more standard format? I tried the following as a test on a single value: time1 = "56:42:12" time2 = time1.split(':') time2 = [int(n) for n in time2] time2.insert(0, time2[0] // 24) time2[1] %= 24 At

问题 I am trying to parse an XML file which is 1.23 GB using SAX parser in Java. I am using Mac OS and JDK 1.7.0.51. Unfortunately, I am getting the following error: The pasrser has encountered more than "64000" entity expansions in this document; this is the limit imposed by the JDK. I have been recommended to get the entity expansion extended but do not know how to do this. Could anyone please help me in this issue. Your help would be very much appreciated. 回答1: I found a solution for this issue

问题 In R, what would be the best way to separate the following data into a table with 2 columns? March 09, 2018 0.084752 March 10, 2018 0.084622 March 11, 2018 0.084622 March 12, 2018 0.084437 March 13, 2018 0.084785 March 14, 2018 0.084901 I considered using a for loop but was advised against it. I do not know how to parse things very well, so if the best method involves this process please be as clear as possible. The final table should look something like this: https://i.stack.imgur.com/u5hII

问题 I have been trying to get at a nested div and its contents but am not able to. I want to access the div with class:'box coursebox'. response = res.read() soup = BeautifulSoup(response, "html.parser") div = soup.find_all('div', attrs={'class':'box coursebox'}) The above code gives a div with 0 elements, when there should be 8. find_all calls before this line work perfectly. Thanks for helping! 回答1: In the case of attributes having more than one value, Beautiful Soup puts all the values into a

The commands are "INC someInteger" "BOMB firstInteger secondInteger" "MOVE firstInteger secondInteger thirdInteger" "MSG someString" "WAIT" I Managed to get this far: #include <boost/spirit/include/qi.hpp> #include <boost/phoenix/phoenix.hpp> using namespace boost::spirit; int main() { std::string
