Split multiple columns into rows using XML

Question

Hi Forum,
I am trying to split 2 columns that each contain values separated by semicolon into single rows. The relation between the values of the two columns is that the order in the cells corresponds to each other.
The data looks like this:
pk    Manufacturer                partnumber
1     Man1; Man2;Man3      PN1;PN2;PN3
2     Man4; Man2;Man5      PN4;PN5;PN6
The result should be:
pk    Manufacturer     partnumber
1       Man1                   PN1
1       Man2                   PN2
1       Man3                   PN3
2       Man4                   PN4
2       Man2                   PN5
2       Man5                   PN6
I am not sure how to format the XML to get a useful Basis for XML.value or XML.query
Any ideas?
TIA
Alex

Hi,
Try like this ,
DECLARE @tmp TABLE (pk INT,Manufacturer NVARCHAR(50),partnumber NVARCHAR(50))
INSERT @tmp SELECT 1,'Man1; Man2;Man3','PN1;PN2;PN3'
INSERT @tmp SELECT 2,'Man4; Man2;Man5','PN4;PN5;PN6'
SELECT * FROM @tmp
SELECT tmp2.pk pk,Manufacturer,partnumber FROM (
SELECT ROW_NUMBER()OVER(ORDER BY tmp1.pk) RN,* FROM (
SELECT pk,
LTRIM(i.value('.','varchar(100)')) Manufacturer
FROM ( SELECT pk, Manufacturer,
CONVERT(XML,'<r><n>'
+ REPLACE(Manufacturer,';', '</n><n>') + '</n></r>') AS X
FROM @Tmp) Spt
CROSS APPLY Spt.X.nodes('//*[text()]') x(i)
) tmp1 ) tmp2
JOIN
(SELECT ROW_NUMBER()OVER(ORDER BY pk) RN,* FROM (
SELECT pk,
j.value('.','varchar(100)') partnumber
FROM ( SELECT pk, partnumber,
CONVERT(XML,'<r><n>'
+ REPLACE(partnumber,';', '</n><n>') + '</n></r>') AS Y
FROM @Tmp) Spt
CROSS APPLY Spt.Y.nodes('//*[text()]') y(j)) tmp2 ) tmp3 ON tmp3.RN = tmp2.RN
