Question

I have a block of text that im taking from a Gedcom (Here and Here) File

The text is flat and basically broken into “nodes”

I am splitting each node on the \r char and thus subdividing it into each of its parts( amount of “lines” can vary)

I know the 0 address will always be the ID but after that everything can be anywhere so i want to test each Cell of the array to see if it contains the correct tag for me to proccess

an example of what two nodes would look like

0 @ind23815@ INDI <<<<<<<<<<<<<<<<<<< Start of node 1
1 NAME Lawrence /Hucstepe/
2 DISPLAY Lawrence Hucstepe
2 GIVN Lawrence
2 SURN Hucstepe
1 POSITION -850,-210
2 BOUNDARY_RECT (-887,-177),(-813,-257)
1 SEX M
1 BIRT 
2 DATE 1521
1 DEAT Y
2 DATE 1559
1 NOTE     * Born: Abt 1521, Kent, England
2 CONT     * Marriage: Jane Pope 17 Aug 1546, Kent, England
2 CONT     * Died: Bef 1559, Kent, England
2 CONT 
1 FAMS @fam08318@
0 @ind23816@ INDI  <<<<<<<<<<<<<<<<<<<<<<< Start of Node 2
1 NAME Jane /Pope/
2 DISPLAY Jane Pope
2 GIVN Jane
2 SURN Pope
1 POSITION -750,-210
2 BOUNDARY_RECT (-787,-177),(-713,-257)
1 SEX F
1 BIRT 
2 DATE 1525
1 DEAT Y
2 DATE 1609
1 NOTE     * Born: Abt 1525, Tenterden, Kent, England
2 CONT     * Marriage: Lawrence Hucstepe 17 Aug 1546, Kent, England
2 CONT     * Died: 23 Oct 1609
2 CONT 
1 FAMS @fam08318@
0 @ind23817@ INDI  <<<<<<<<<<< start of Node 3

So a when im done i have an array that looks like
address , string
0 = "1 NAME Lawrence /Hucstepe/"
1 = "2 DISPLAY Lawrence Hucstepe"
2 = "2 GIVN Lawrence"
3 = "2 SURN Hucstepe"
4 = "1 POSITION -850,-210"
5 = "2 BOUNDARY_RECT (-887,-177),(-813,-257)"
6 = "1 SEX M"
7 = "1 BIRT "
8 = "1 FAMS @fam08318@"

So my question is what is the best way to search the above array to see which Cell has the SEX tag or the NAME Tag or the FAMS Tag
this is the code i have
private int FindIndexinArray(string[] Arr, string search)
{
    int Val = -1;
    for (int i = 0; i < Arr.Length; i++)
    {
        if (Arr[i].Contains(search))
        {
            Val = i;
        }
    }
    return Val;
}

But it seems inefficient because i end up calling it twice to make sure it doesnt return a -1
Like so
            if (FindIndexinArray(SubNode, "1 BIRT ") != -1)

            {

                // add birthday to Struct

                I.BirthDay = SubNode[FindIndexinArray(SubNode, "1 BIRT ") + 1].Replace("2 DATE ", "").Trim();

            }


sorry this is a longer post but hopefully you guys will have some expert advice
												

Answer 1

Can use the static method FindAll of the Array class:
It will return the string itself though, if that works..

string[] test = { "Sex", "Love", "Rock and Roll", "Drugs", "Computer"};
Array.FindAll(test, item => item.Contains("Sex") || item.Contains("Drugs") || item.Contains("Computer"));

The => indicates a lamda expression. Basically a method without a concrete implementation.
You can also do this if the lamda gives you the creeps.

//Declare a method 

     private bool HasTag(string s)
     {
         return s.Contains("Sex") || s.Contains("Drugs") || s.Contains("Computer");
     }

     string[] test = { "Sex", "Love", "Rock and Roll", "Drugs", "Computer"};
     Array.FindAll(test, HasTag);
