String with comma-separated values and newlines: split values and create arrays for each newline

With these it helps I have a string like this (from a form submission):
s = "apple, banana\r\ncherries\r\n\r\ngrapes, blue berries \r\n\r\n \r\norange"
s.each_line.reject { |l| l =~ /^\s+$/ }.map { |l| l.strip.split(', ') }

XSLT 2.0 : Split a string into comma separated values

Tag : string , By : user185283

seems to work fine I am new to XSLT and have a requirement where in i have to manipulate a string as below. , Here is some XSLT/XPath 2.0 approach:
  exclude-result-prefixes="xs mf"

  <xsl:function name="mf:sub-sequences" as="xs:string*">
    <xsl:param name="input" as="xs:string"/>
    <xsl:param name="min-length" as="xs:integer"/>
    <xsl:sequence select="reverse(
                            for $length in $min-length to string-length($input)
                            return substring($input, 1, $length)

  <xsl:template name="main">
    <xsl:variable name="s" select="'12345'"/>
    <xsl:value-of select="mf:sub-sequences($s, 2)" separator=","/>

I wish this help you I have this code: , You can use a regex in the split, like so:

String.split() - How to diferentiate between tab separated values and comma separated values?

Tag : java , By : kbrust

help you fix your problem line.split does not return null when the regular expression doesn't find any matches. Instead it returns an array with the whole line as the first and only element.
Therefore the first condition ais always true.

I hope this helps . Used a #Temp table to store the parsed results. Perhaps you can migrate into a cte
Declare @YourTable table (ID int,Data varchar(max))
Insert Into @YourTable values

Select A.ID
      ,ColName = 'Data'+cast(DENSE_RANK() over (Order By RetVal) as varchar(25))
Into #Temp
From @YourTable A
Cross Apply (
              Select RetSeq = Row_Number() over (Order By (Select null))
                    ,RetVal = LTrim(RTrim(B.i.value('(./text())[1]', 'varchar(max)')))
              From (Select x = Cast('<x>'+ Replace(A.Data,',','</x><x>')+'</x>' as xml).query('.')) as A 
              Cross Apply x.nodes('x') AS B(i)
             ) B

Declare @SQL varchar(max)
Select  @SQL = Stuff((Select Distinct ',' + QuoteName(ColName) From #Temp For XML Path('')),1,1,'')   
Select  @SQL = 'Select ID,' + @SQL + ' 
                From (Select ID,ColName,RetVal From #Temp) A
                Pivot (max(RetVal) For ColName in (' + @SQL + ') ) p'

ID  Data1   Data2   Data3
1   abc     def     NULL
2   abc     def     NULL
3   NULL    def     ghi
