Function STRING_SPLIT in SQL Server 2014

With a split function (there are many ways to do this prior to SQL Server 2016, here is one):

CREATE FUNCTION [dbo].[SplitString]
(
    @List NVARCHAR(MAX),
    @Delim VARCHAR(255)
)
RETURNS TABLE
AS
    RETURN ( SELECT [Value] FROM 
      ( 
        SELECT 
          [Value] = LTRIM(RTRIM(SUBSTRING(@List, [Number],
          CHARINDEX(@Delim, @List + @Delim, [Number]) - [Number])))
        FROM (SELECT Number = ROW_NUMBER() OVER (ORDER BY name)
          FROM sys.all_objects) AS x
          WHERE Number <= LEN(@List)
          AND SUBSTRING(@Delim + @List, [Number], LEN(@Delim)) = @Delim
      ) AS y
    );

The query becomes simpler than a bunch of charindex etc. and an unknown endpoint:

DECLARE @String VARCHAR(1024) = 'LogsID = "1" Value="1" Value="2" Value="3"';

;WITH x AS
(
  SELECT value, p = PARSENAME(value,1) 
  FROM dbo.SplitString(@String, 'Value=')
),
l AS
(
  SELECT LogsID = PARSENAME(LTRIM(SUBSTRING(value,CHARINDEX('=',value)+1,255)),1) 
  FROM x WHERE p IS NULL
)
SELECT l.LogsID,y.p FROM l
CROSS JOIN (SELECT p FROM x WHERE p IS NOT NULL) AS y;

The STRING_SPLIT function in SQL Server is not available before SQL Server 2016, you should have at least compatibility level 130 as per Microsoft's docs.
