extract

问题 My web app is an e-mail service. It stores email messages in MySQL database and email attachments are on a disk. The database is similar to: ---------------------------------------------------------------------- | id | sender | receiver | subject | body | attach_dir | attachments | ---------------------------------------------------------------------- | 2 | 444 | 555 | Apples | Hey! | /mnt/emails| att1.doc\r\n| | | | | | | | att2.doc\r\n| ------------------------------------------------------

问题 I have 14 different XML files like this and I'm trying to get ActionUnit Number values (ex. 45 and 5). I need to do it for the other 13 XML files too with a loop. After that, I need to create subfolders for each value that I extracted. I tried a code for value extraction but I get none as a result; import xml.etree.cElementTree as ET tree= ET.ElementTree(file=r'C:\Users\LME_s\Desktop\python quiz\Sessions\1\S001-001-oao_aucs.xml') root= tree.getroot() for chld in root: print (chld.get(

问题 When looking for some logs in one file I got two types of logs (one with white spaces and one without). I would now like to extract doSomething and doAnotherThing out of these logs with one regular expression. Logfile 1: "taskType":"doSomething" Logfile 2: "taskType" : "doAnotherThing" I coded this regular expression: taskType.....(?<taskType1>\w+) It works good for Logfile 1 but not for Logfile 2, because it cuts the first two characters of the word. Is there a way to eliminate this issue?

问题 Hi I need to remain only with the day of each date: df<-data.frame(x=c("2014-07-24 00:00:00", "2014-07-24 00:00:00", "2014-07-11", "2014-07-11" ,"2014-07-16" ,"2014-07-14")) as.Date(df$x,format="%Y-%m-%d" ) I tried this: df$dia<-as.Date(df$x, format="%d") But I get a full date and different from the orginal. I don't want to install another package to do this. How can I solve it? Thanks 回答1: Are you looking for format ? format(as.Date(df$x,format="%Y-%m-%d"), format = "%d") # [1] "24" "24" "11

问题 I'm working in google apps script. If I start with a range like range A1:E5, that's a 5x5 array. I want to return range C1:D5, a 5x2 array. Start with a 2d array and return only selected 'columns'. That's basically it. I think it's a fundamental operation, but I'm really struggling. I have my code below, but I'm open to any options that use arrays (not ranges, so as to avoid pinging the server unnecessarily). Note that I do want to be able to pass an array parameter for columns, so [2,3,4] or
