I'd like to take a CSV file living server-side and display it dynamically as an html table. E.g., this:

Name, Age, Sex
"Cantor, Georg", 163, M

should become this:

<html><body><table>
<tr> <td>Name</td> <td>Age</td> <td>Sex</td> </tr>
<tr> <td>Cantor, Georg</td> <td>163</td> <td>M</td> </td>
</table></body></html>

Solutions in any language are welcome.

Does it work if you escape the quoted commas with \ ?

Name, Age, Sex

"Cantor\, Georg", 163,M

Most delimited formats require that their delimiter be escaped in order to properly parse.

A rough Java example:

import java.util.Iterator;

public class CsvTest {

    public static void main(String[] args) {
        String[] lines = { "Name, Age, Sex", "\"Cantor, Georg\", 163, M" };

        StringBuilder result = new StringBuilder();

        for (String head : iterator(lines[0])) {
            result.append(String.format("<tr>%s</tr>\n", head));
        }

        for (int i=1; i < lines.length; i++) {
            for (String row : iterator(lines[i])) {
                result.append(String.format("<td>%s</td>\n", row));
            }
        }

        System.out.println(String.format("<table>\n%s</table>", result.toString()));
    }

    public static Iterable<String> iterator(final String line) {
        return new Iterable<String>() {
            public Iterator<String> iterator() {
                return new Iterator<String>() {
                    private int position = 0;

                    public boolean hasNext() {
                        return position < line.length();
                    }

                    public String next() {
                        boolean inquote = false;
                        StringBuilder buffer = new StringBuilder();
                        for (; position < line.length(); position++) {
                            char c = line.charAt(position);
                            if (c == '"') {
                                inquote = !inquote;
                            }
                            if (c == ',' && !inquote) {
                                position++;
                                break;
                            } else {
                                buffer.append(c);
                            }
                        }
                        return buffer.toString().trim();
                    }

                    public void remove() {
                        throw new UnsupportedOperationException();
                    }
                };
            }
        };
    }
}
