Read XML column attributes in to two columns DimType and Dimvalue  from the below example also retrieve the data matching values[DimTypes (WIDTH or Height)].

‘<dimensions>

<dimension name=”width”  value=”12.77″/>

<dimension name=”height”  value=”0.14″/>

<dimension name=”depth”      value=”12.92″/>

</dimenstions>’

 SQL:-

DECLARE @xml XML
SELECT @xml = 
'<dimensions>
  <dimension name="height" value="0.14" /> 
  <dimension name="width"  value="12.77"/> 
</dimensions>'
SELECT  x.v.value('@name[1]', 'VARCHAR(100)') AS dimtype ,
        x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
FROM    @xml.nodes('/dimensions/dimension') x(v)

create table #demo (field1 xml)
insert into #demo (field1) 
values ('<dimensions>
  <dimension name="height" value="0.14" /> 
  <dimension name="width"  value="12.77"/> 
</dimensions>')
SELECT  x.v.value('@name[1]', 'VARCHAR(100)') AS dimtype ,
        x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
from #demo
cross apply field1.nodes('/dimensions/dimension') x(v)

Select data for DimType “height and Width”

DECLARE @xml XML
SELECT @xml = 
'<dimensions>
  <dimension name="height" value="0.14" /> 
  <dimension name="width"  value="12.77"/> 
   <dimension name="depth"   value="12.92"/>
</dimensions>'
SELECT  x.v.value('@name[1]', 'VARCHAR(100)') AS dimtype ,
        x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
FROM    @xml.nodes('/dimensions/dimension[@name = "height" or @name = "width"]') x(v)

Using Temp table and Join –

create table #demo (field1 xml)
insert into #demo (field1) 
values ('<dimensions>
 <dimension name="height" value="0.14" /> 
 <dimension name="width" value="12.77"/> 
</dimensions>')
SELECT x.v.value('@name[1]', 'VARCHAR(100)') AS dimtype ,
 x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
from #demo
cross apply field1.nodes('/dimensions/dimension[@name = "height" or @name = "width"]') x(v)

Using SQL Where Clause to fetch dimension type data ‘HEIGHT’ or ‘WIDTH’

CREATE TABLE #demo (field1 xml)
INSERT INTO #demo (field1) 
values ('<dimensions>
  <dimension name="height" value="0.14" /> 
  <dimension name="width"  value="12.77"/> 
  <dimension name="depth"   value="12.92"/>
</dimensions>')
select * from #demo
select 
dimtype,
dimvalue
FROM
(
SELECT  x.v.value('@name[1]', 'VARCHAR(100)') AS dimtype ,
        x.v.value('@value[1]', 'VARCHAR(100)') AS dimvalue
from #demo
cross apply field1.nodes('/dimensions/dimension') x(v)
)T
where
T.dimtype in('height','width')
