Replace double quotes with a single quote within a double quoted string

Hi Froum.

I have tried in vain to find a solution for this problem - I'm trying to replace any double quotes within a quoted string with a single quote, leaving everything else as is.

I have the following data:

Before:
Code:
0000001111,"IBD","601725","6017257000681563","0430","163458","002820","002820000000","E0107815","1801 3E AVENUE         VAL-D"OR
 QCCA","0200","","","WD","CH","","4000320275","","124","124",,60.00,60.00,60.00,0.00,0.45,60.45,0.037500,"APP","00","EXC","5"


After:
Code:
0000001111,"IBD","601725","6017257000681563","0430","163458","002820","002820000000","E0107815","1801 3E AVENUE         VAL-D'OR
 QCCA","0200","","","WD","CH","","4000320275","","124","124",,60.00,60.00,60.00,0.00,0.45,60.45,0.037500,"APP","00","EXC","5"


In this example, VAL-D"OR is replaced as VAL-D'OR.

Thanks.

try:
Code:
sed 's/VAL-D"OR/VAL-D\x27OR/' in

thanks for your reply.

Sorry that was just an example.

I need to replace all double quotes occurences within a quote string with a single quote.

Text can be anything.

Could you please explain what a "quote[d] string" as per your definition is?

Suppose a "quoted string" in the usual sense:

Code:
quoted string begins here ->"quoted string"<-and ends here

Now suppose there would be a double quote within these two:

Code:
quoted string begins here ->"quoted"string"<-and ends here

The quoted string would now be "quoted" and not "quoted["]string", no? If not, please explain how a program is supposed to find out.

Fundamental rule of parsing: its easy once you can define what you really want. ;-))

I hope this helps.

OK, so in this "example" is the field constant?
If not give us something fixed to work on...

I hope I can be clear on my explanation.

We are basically receiving a csv file from the vendor and any field they deemed as text, they will enclose with a double quote.

The problem arises when they also have/use a double quote as part of the data.

In my example, it's an address field of a customer and the name of the street happens to have a quote in it and vendor has used double quotes for the data (Ex: VAL D"OR instead of VAL D'OR). If vendor used a single quote instead, everything would have been okay.

This is causing us issue when cleaning up the file using sed because there's an unmatched quotes in the file. That's why I'm looking to replace any double quotes that is part of the data with a single one.

Hope this answers your questions.

Thanks.
