问题 So, I have a json file with nested indexes. There's an index called "user" which has a subindex called "lang", along with a lot of other subindexes. I only want to extract the "lang" fields out and save it as csv. For the saving as csv part, I can use one of the open source "json2csv" codes, I guess. Could someone help me out with extracting the "lang" fields? 回答1: Use JSON.stringify() to convert the data into a string, then use match with a RegExp to return an array of specified key/value

问题 I am trying to create multi-user system for CV managing using Drupal. The basic idea is: Each User has his own CV. Each CV has several predefined sections as Education, Work experience, etc. Each Section consists of unlimited {Dates range - Text} entries. I've created two new content types - CV and Date_Range_Text but I cannot link them together, e.g. to make Date_Range_Text a complex/nested content type, used in the CV's sections entries. Do you have any ideas? Thanks. 回答1: I would use the

Possible Duplicates: RegEx match open tags except XHTML self-contained tags .NET Regex balancing groups expression - matching when not balanced For example, if I had the input: [quote]He said: [quote]I have no idea![/quote] But I disagree![/quote] And another quote: [quote]Some other quote here.[/quote] How can I effectively grab blocks of quotes using regular expressions without grabbing too much or too little?

问题 Just to begin I know there are a couple similarly-titled questions on here, but none are explained quite this way nor is the problem scope the same. I want to add nested dictionary entries dynamically. The use case is thus: I have a python script that is monitoring the network. A dictionary is created for each observed IP protocol (tcp, udp, icmp) that is observed. Then a sub-dictionary is created with a key that is the destination port (if one exists) for each of these IP protocols (80, 443,

问题 I have imported a huge json file into mongoDB. It has imported as one whole document (with one _id).

问题 This question derives from the question and answer given here: How to build a custom function that uses externally defined values with a string condition in R The remark concerning the combination of 2 equations as an argument makes me curious and brings up 2 following questions: 1) How can I use multiple equations based on another string-value (a grouping variable) which I will add to the eq_df? (expected result: a numeric vector of differing length for each cell in data_df$iso_value_p) 2)

问题 I am working with Oracle PL/SQL. There are two cursors, namely c1 and c2. v_temp VARCHAR(50); For s1 IN c1 LOOP --do something FOR s2 IN c2 LOOP --do something v_temp := s1.s2.xxx; --PLS-00302: component 's2' must be declared END LOOP; END LOOP; s2.xxx gives a column name, and with that column name I hope to assign the value of that column from s1 to v_temp . For example: In the first iteration, s2.xxx is 'column1' , I would like to assign s1.column1 to v_temp . In the second iteration, s2
