I have a json output on my notepad and i know it is not in the correct format. At the end of each line there is a time stamp which is causing the bad format. I want to get rid of it using find and replace since the file is pretty big. The format is as follows :
"eventtimestamp": "05 23 2017 04:01:02"}
The above piece comes in at the end of every line. How can i get rid of it using find a replace or any other way.
All help is appreciated.
Thank you
If you need to alter every line in a consistent way then regex find/replace is a good option. Free tools like atom.io, Notepad++, and plenty of others offer this feature.
Assuming "eventtimestamp" is constant, then a simple regex that says "find everything starting with "eventtimestamp" and up to a '}'" will work.
"eventtimestamp".*(?=})
And "replace" that with an empty string.
ps) here's a demo of the regex in regexr.com--hovering over the parts of the pattern will explain what they do.
If you are not sure that the eventtimestamp field always comes in at the end of a line and/or as the last element of the object, prefer that kind of pattern: "eventtimestamp":\s*"[^"]+",?.
Note the useful surrounded excepted character class pattern "[^"]+" that can be declined with any other delimiter.

Introduction
We have a pretty standard way of importing .txt and .csv into our data warehouse using SSIS.
Our txt/csvs are produced with speech marks as text qualifiers. So a typical file may look like the below:
"0001","025",1,"01/01/19","28/12/18",4,"ST","SMITH,JOHN","15/01/19"
"0002","807",1,"01/01/19","29/12/18",3,"ST","JONES,JOY","06/02/19"
"0003","160",1,"01/01/19","29/12/18",3,"ST","LEWIS,HANNAH","18/01/19"
We have set all our SSIS packages to strip out the speech marks by setting Text Qualifier = "
Problem
However, as some of our data entry is done manually, speech marks are sometimes used - particularly in free text fields such as NAME where people have nicknames/alias. This causes errors in our SSIS loading.
An example of a problematic row would be:
"0004","645",1,"01/01/19","29/12/18",3,"ST","MOORE,STANLEY "STAN"","12/04/19"
My question
Is there a way to somehow strip out these problematic speech marks? i.e. the speech marks surrounding "STAN", so that column would be treated as MOORE, STANLEY STAN.
If there was a way within SSIS to do this, great. If not, we are open to other ideas outside of SSIS.
Solution needs to be scalable as we have hundreds of SSIS packages where this problem can occur.
I have a few suggestions:
I know Excel has a setting that says something like "Treat Consecutive Delimiters as one."
Change your delimiter to something else, like a pipe (the thing above the backslash, not sure what it is called elsewhere, looks like a vertical line). You can distinguish delimiters from quote marks that are meant to be included in the resulting value because any string delimiter either immediately precedes or immediately follows a comma. A quote character anywhere else is not a delimiter.
If you do not need to pass the data through any T-SQL you might want to replace non-delimiter quotes with single quotes or, depending on the final output, maybe the html entity (") instead.
Hope this helps,
Joey
I am reading data (combination of letters and numbers) from an excel sheet and put it into a text field in target application, where the input should yield a unique item from a database.
However there (sometimes) is a whitespace behind the data in the excel cell, which results in a "no data found" when this whitespace is entered into the search field in target application. The whitespace does not seem to be a space though, since i am unable to trim that whitespace AA-internally. I guess it is a (or some similar html special character).
edit: confirmed to be a by now.
Q: How can i get rid of such characters AA internally?
Tried: Neither (a) Trim, (b) Replace " " ->"", nor (c) Replace " "->"" work.
Workaround: I am currently checking for the length of the data provided: if its longer than 10 chars i only take the leftmost 10 chars. This works here, since its a business rule for the data i am working with, but i am still interested in an original solution, since there may be upcoming cases, where no business rule will help me out.
AA Version: 11.3.1
Thankful for input...
Okay, since it's non-breaking spaces character, you can replace it using Regex in replace command.
Find: \u00a0
Options: Regular Expression.
Got rid of it using Replace Command with RegEx ticked:
[^a-z A-Z 0-9]
I am using a simple program to read CSV file, somehow I noticed when I created a CSV using EXCEL or windows based computer go library fails to read it. even when I use cat command it only shows me last line on the terminal. It always results in this error extraneous " in field.
I researched somewhat than I found it is somewhat related to carriage return differences between OS.
But I really want to ask how to make a generic csv reader. I tried reading the same csv using pandas and it was reading successfully. But i am not been able to achieve this using my Go code.
Also screen shot of correct csv Is here
Your file clearly shows that you've got an extra quote at the end of the content. While programs like pandas may be fine with that, I assume it's not valid csv so go does return an error.
Quick example of what's wrong with your data: https://play.golang.org/p/KBikSc1nzD
Update: After your update and a little bit of searching, I have to apoligize, the carriage return does matter and seems to be tha main culprit here, Go seems to be ok handling the \r\n windows variant but not the \r one. In that case what you can do is wrap the bytes.Reader into a custom reader that replaces the \r byte with the \n byte.
Here's an example: https://play.golang.org/p/vNjzwAHmtg
Please note, that the example is just that, an example, it's not handling all the possible cases where \r might be a legit byte.
I am writing a CSV parser and I want it to comply with this standards. It states:
Each record is located on a separate line, delimited by a line break (CRLF)
How should I handle rows ending with only CR of LF character? Should I treat them as literals and pass to field, interpret as a row end. Or maybe dub the file malformed?
I guess, that most flexible solution would be to accept either type of line end, but I am trying to figure out what standards say.
What do you think about it?
You should certainly not treat them as malformed, because there can be different line endings on Linux, Windows and Mac for example.
It's better to support them all.
Also, fields can have newlines in them as well, if they are properly quoted. So you'll need to check for that too.
For example:
123,"test on 2
lines",456
is a valid csv row.
I have a document that was converted from PDF to HTML for use on a company website to be referenced and indexed for search. I'm attempting to format the converted document to meet my needs and in doing so I am attempting to clean up some of the junk that was pulled over from when it was a PDF such as page numbers, headers, and footers. luckily all of these lines that need to be removed are in blocks of 4 lines unfortunately they are not exactly the same therefore cannot be removed with a simple literal replace. The lines contain numbers which are incremental as they correlate with the pages. How can I remove the following example from my html file.
Title<br>
10<br>
<hr>
<A name=11></a>Footer<br>
I've tried many different regular expression attempts but as my skill in that area is limited I can't find the proper syntax. I'm sure i'm missing something fairly easy as it would seem all I need is a wildcard replace for the two numbers in the code and the rest is literal.
any help is apprciated
The search & replace of npp is quite odd. I can't find newline charactes with regular expression, although the documentation says:
As of v4.9 the Simple find/replace (control+h) has changed, allowing the use of \r \n and \t in regex mode and the extended mode.
I updated to the last version, but it just doesn't work. Using the extended mode allows me to find newlines, but I can't specify wildcards.
However, you can use the macros to overcome this problems.
prepare a search that will find a unique passage (like Title<br>\r\n, here you can use the extended mode)
start recording a macro
press F3 to use your search
mark the four lines and delete them
stop recording the macro ... done!
Just replay it and it deletes what you wanted to delete.
If I have understood your request correctly this pattern matches your string:
Title<br>( ?)\n([0-9]+)<br>( ?)\n<hr>( ?)\n<A name=([0-9]+)></a>Footer<br>
I use the Regex Coach to try out complicated regex patterns. Other utilities are available.
edit
As I do not use Notepad++ I cannot be sure that this pattern will work for you. Apologies if that transpires to be the case. (I'm a TextPad man myself, and it does work with that tool).
