Handling CSV file [duplicate] - c++

This question already has answers here:
C++ CSV line with commas and strings within double quotes
(3 answers)
Closed 5 years ago.
I am using CSV file with comma as delimiter
getline(strGetLine, word, ',')
I have a problem while reading something which as comma in between
Example -"mysentence,fromCSV"
Please let me know how to handle it.

I would recommend using a library, since this is not a new problem and has been solved several times.
The first example I can find is https://github.com/ben-strasser/fast-cpp-csv-parser, but you could also do something with Boost Spirit if you felt inclined.

I am having a hard time with Go's regex. It seems it's different than other language, can someone help me on this.
Obj. I want MustCompile to find all repeated characters in the string.

Can someone tell me what I am doing wrong?

You can use external system tools to do that. In c++, such utilities can be launched using the function system()

http://expat.sourceforge.net/ and http://msdn.microsoft.com/en-us/magazine/cc163436.aspx two more alternatives apart from http://xerces.apache.org/xerces-c/ as mentioned by mtahmed. There are plenty more. Please compare them based on your requirement.
You can use an XML parser library. Here is a link to one such library: http://xerces.apache.org/xerces-c/

C++ StringTokenizer for a multichar separator [duplicate]

Possible Duplicate:
Split on substring
I want to separate an std::string by a two character separator, i.e. I'm looking for string tokenizer that can accept separators which are NOT a single character. Boost's tokenizer allows for multiple characters to be specified as separators, but this means that it'll consider any individual character as a separator, whilst what I want is to say that the separator is a particular sequence of characters, viz. a substring.
I'd initially thought I would quickly find the answer to this with a couple of google searches, but having just been proven wrong by a couple of wasted hours, I ask: ideas anyone?
QT's QString::split() can do this.
