Find comma in quotes with regex and replace with HTML equiv

Question

I\'m looking in a string such as:

\"Hello, Tim\"

Land of the free, and home of the brave

And I need it to become:

\"Hello&         


        

Answer 1

result = subject.replace(/("[^"]+?),([^"]*?")/img, "$1,$2");

This will work properly with your example, the only catch is it will not work if you have multiple , inside of the ". If you need it to work with multiple , inside of the " then take a look at this for a more complete way to parse CSV data with javascript.

Answer 2

With the above string as variable html you can use following code:

var m = html.match(/"[\s\S]*"/);
html = html.replace(m[0], m[0].replace(/,/g, ','));

OUTPUT

"Hello, Tim"

Land of the free, and home of the brave

Answer 3

var str = '"Hello, Tim"\n\
\n\
Land of the free, and home of the brave';

str
.split('"')
.map(function(v,i){ return i%2===0 ? v : v.replace(',',','); })
.join('"');

Answer 4

It is probably easier with a callback function to replace:

s = s.replace(/"[^"]*"/g, function(g0){return g0.replace(/,/g,',');});

At the first step we find all quotes, and replace just the commas in them.

You can even allow escaping quotes:

• CSV style (with two double quotes) - /"([^"]|"")*"/g
• String literal style - /"([^"\\]|\\.)*"/g
