Match.NextMatch Method

Returns a new Match with the results for the next match, starting at the position at which the last match ended (at the character beyond the last matched character).

[Visual Basic]
Public Function NextMatch() As Match
[C#]
public Match NextMatch();
[C++]
public: Match* NextMatch();
[JScript]
public function NextMatch() : Match;

Return Value

The next regular expression Match object.

Remarks

This function is similar to calling Match again and passing (Index+Length) as the new starting position, but it differs from calling Match directly because it handles zero-length match cases in a way that guarantees progress to the end of the string.

Example

[Visual Basic] 
Dim text As String = "One car red car blue car"
Dim pat As String = "(\w+)\s+(car)"
' Compile the regular expression.
Dim r As Regex = new Regex(pat, RegexOptions.IgnoreCase)
' Match the regular expression pattern against a text string.
Dim m As Match = r.Match(text)
Dim matchcount as Integer = 0
While (m.Success)
   matchCount += 1
   Console.WriteLine("Match" & (matchCount))
   Dim i As Integer
   For i = 1 to 2
      Dim g as Group = m.Groups(i)
      Console.WriteLine("Group" & i & "='" & g.ToString() & "'")
      Dim cc As CaptureCollection = g.Captures
      Dim j As Integer 
      For j = 0 to cc.Count - 1
     Dim c As Capture = cc(j)
         Console.WriteLine("Capture" & j & "='" & c.ToString() _
            & "', Position=" & c.Index)
      Next j
   Next i
   m = m.NextMatch()
End While

[C#] 
string text = "One car red car blue car";
string pat = @"(\w+)\s+(car)";
// Compile the regular expression.
Regex r = new Regex(pat, RegexOptions.IgnoreCase);
// Match the regular expression pattern against a text string.
Match m = r.Match(text);
int matchCount = 0;
while (m.Success) 
{
   Console.WriteLine("Match"+ (++matchCount));
   for (int i = 1; i <= 2; i++) 
   {
      Group g = m.Groups[i];
      Console.WriteLine("Group"+i+"='" + g + "'");
      CaptureCollection cc = g.Captures;
      for (int j = 0; j < cc.Count; j++) 
      {
         Capture c = cc[j];
         System.Console.WriteLine("Capture"+j+"='" + c + "', Position="+c.Index);
      }
   }
   m = m.NextMatch();
}

[C++] 
String* text = S"One car red car blue car";
String* pat = S"(\\w+)\\s+(car)";
// Compile the regular expression.
Regex* r = new Regex(pat, RegexOptions::IgnoreCase);
// Match the regular expression pattern against a text string.
Match* m = r->Match(text);
int matchCount = 0;
while (m->Success) 
{
   Console::WriteLine(S"Match{0}", __box(++matchCount));
   for (int i = 1; i <= 2; i++) {
      Group* g = m->Groups->Item[i];
      Console::WriteLine(S"Group{0}='{1}'", __box(i), g);
      CaptureCollection* cc = g->Captures;
      for (int j = 0; j < cc->Count; j++) 
      {
         Capture* c = cc->Item[j];
         System::Console::WriteLine(S"Capture{0}='{1}', Position={2}", __box(j), c, __box(c->Index));
      }
   }
   m = m->NextMatch();
}
