Subject [jira] [Commented] (CSV-155) Get remaining unformatted text
Date Tue, 11 Aug 2015 06:11:47 GMT

    [ https://issues.apache.org/jira/browse/CSV-155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14681296#comment-14681296

Jason Steenstra-Pickens commented on CSV-155:
---------------------------------------------

Basically I have a String that contains CSV with a header row. I want to use the CSVParser
to read the header row so that I can validate that the headers match what is expected. I then
need to get the rest of the CSV without the first header row but still as a String (rather
than a List of CSVRecord objects).

> I have the requirement where I need to parse the headers of a CSV string so that I can
validate them and then remove those headers.
> The problem is that the CSVParser creates an internal ExtendedBufferedReader from the
given reader (which in my case is a StringReader). Reading the first record will read and
buffer additional records so if I then try and read directly from the StringReader it does
not return anything.
> To solve this I need to be able to do one of the following:
> # pass in my own ExtendedBufferedReader (so would need to be made public)
> # have a new getter method to be able to retrieve the internal ExtendedBufferedReader
(or as a BufferedReader, either will do)
> # have a new method on the CSVParser to be able to retrieve the remaining raw records.
> The current workaround is to read all the records and then write all the records except
the first back out to a StringWriter but this is a lot of unnecessary work and code. This
doesn't really work since it reader and writing it back out has a very high chance of modifying
the quotes, escapes, whitespace etc.
