trim

问题 So basically I have a process that outputs a text file that is pipe delimited, looks something like this: |abc123|1*|004|**gobbligook|001|%|2014-01-01||||||||||||| This is just an example, and I'm not sure if the answer involves regular expressions. If it does i will put the actual line. Anyways ISSUE So for this example the import process that accepts this file is looking for 8 pipes, but there are 20, if it sees any more pipes after the 8 it's looking for the import process fails.

问题 I would like to get a part from a string. Im not familiar with VBA or unusual excel functions, but I think maybe a macro or a VBA code can help me. I need to cut down everything from the whole string from the cell, except what is after the Total. To clear this, I need the numbers which stand after the total.

问题 I want to remove leading and trailing spaces ( SP, \n, \t, eventually \r ) from strings in MySQL. Data already are on MySQL tables and I can't retrieve them for processing in PHP as this should be too slow. I tried this kind of syntax: UPDATE table set field = TRIM(BOTH '\t' FROM TRIM(BOTH '\n' FROM TRIM(field))); But, this way removes spaces, then \n , then \t in this order, and I want to remove all spaces disregarding their order (ie: "\n\t \t\n\n\t hello\t\n\n \t " would return only "hello

Also there could be a lot of variants of string end: "\r\n\r\n", "\r\n", "\n\r\n" and so on... Thanks. 回答1: Your string contains not only whitespace but also new line

问题 How do you trim white spaces in both the keys and values in a JavaScript Object recursively? I came across one issue in which I was trying to "clean" a user supplied JSON string and send it into my other code for further processing. Let's say we've got a user supplied JSON string whose property key and value are of type "string". However, what's problematic in this case is that the keys and values are not as clean as desired. Say a { " key_with_leading_n_trailing_spaces ": " my_value_with
