Lets look at them one step at a time.
Firstly, Dolzam (Ultram) from mexico, quoted values. Dolzam (Ultram) blogs, This is by far the easiest of all the conditions - find any length of text between two quotes. Buy Dolzam (Ultram) Without Prescription, We'll use a non-greedy expression (the question mark after the star) to ensure we don't over-extend the length of text that we match:
[csharp]
private const string
Template_QuotedValues = @"""(?<content>.*?)""";
[/csharp]
The next easiest type of match to capture are non-quoted, non-zero length values. To do this, we'll simply look for one or more characters which are not a comma, low dose Dolzam (Ultram). Again, Dolzam (Ultram) from canada, we're using a non-greedy match:

private const string
Template_UnquotedValues = @"(?<content>[^,]+?)";

Order Dolzam (Ultram) from mexican pharmacy, The last type of match we need to cater for is non-quoted, zero-length matches. This is the trickiest of the three situations, Dolzam (Ultram) no prescription, since there's "nothing" to actually match on. So instead, we look zero repetitions of any character, immediately after a delimiter, Buy Dolzam (Ultram) Without Prescription. Dolzam (Ultram) brand name, Since the first value in the list may be empty, the possible values for our delimiter are either the start of string (specified by the hat - ^), or a comma:
[csharp]
private const string
Template_EmptyValues = @"(?<=(?:, Dolzam (Ultram) dangers,|^))(?<content>.{0})", Dolzam (Ultram) dosage, [/csharp]
The final piece of the puzzle is the delimiters. Since we're matching from left-to-right, we can assume that every match will be followed either by a comma, Dolzam (Ultram) schedule, or the end of the string. Dolzam (Ultram) mg, We'll use a non-capturing group since we don't want the delimiter to be explicitly captured in a group.
[csharp]
private const string
Template_Delimiter = @"(?=(?:,|$))";
[/csharp]
Now, purchase Dolzam (Ultram), to put it all together. Buy Dolzam (Ultram) Without Prescription, We have our three types of matches that we're expecting, and our delimiter, so all we need to do is create a single RegEx for it all. Dolzam (Ultram) price, Here goes:
[csharp]
private const string
// Any length value within quotes...
Template_QuotedValues = @"""(?<content>.*?)""",
// .., where can i cheapest Dolzam (Ultram) online. or values with at least 1 character, What is Dolzam (Ultram), not in quotes...
Template_UnquotedValues = @"(?<content>[^,]+?)", where to buy Dolzam (Ultram),
// ...or zero-length matches, Order Dolzam (Ultram) from United States pharmacy, not in quotes...
Template_EmptyValues = @"(?<=(?:,|^))(?<content>.{0})",
// .., Buy Dolzam (Ultram) Without Prescription. followed either a comma, or end of string
Template_Delimiter = @"(?=(?:, purchase Dolzam (Ultram) online no prescription,|$))";
// Now join as one Template - notice the OR condition (pipe)
// between the three match types
readonly static private string
Template = String.Format("({0}|{1}|{2}){3}", Dolzam (Ultram) wiki, Template_QuotedValues,
Template_UnquotedValues,
Template_EmptyValues,
Template_Delimiter);
// Finally, our RegEx.
readonly static private Regex CsvSplitterRegex
= new Regex(Template, RegexOptions.Compiled);
[/csharp]
Was that so bad. ;-) Iterating through the list of values in our comma separated list is now a piece of cake.
[csharp]
// Assume CSV is in "record" field
foreach (Match match in CsvSplitterRegex.Matches(record))
{
Console.WriteLine("Match value: {0}",
match.Groups["content"].Value);
}
[/csharp]
