Hello!

Can someone help me with some sql that will return to me some data from an xml object?

I have the following xml:
<root>
  <FromDate>2016-03-01</FromDate>
  <ToDate>2016-03-25</ToDate>
  <Variables>
    <Variable>
      <Name>pain</Name>
    </Variable>
    <Variable>
      <Name>unit</Name>
    </Variable>
  </Variables>
  <Filters>
    <Filter>
      <Name>diagnose</Name>
      <Values>
        <Value>1461</Value>
        <Value>1462</Value>
      </Values>
    </Filter>
  </Filters>
</root>

Open in new window

I would like to extract the text of the <Value> nodes under the <root> <Filters> <Filter><Values> where the text in <root> <Filters> <Filter><Name> is "diagnose".

The resuting nvarchar should be "1461, 1462"

I am used to building strings like this from tables using something like:
 select @CategoryAxis = @CategoryAxis + '<Category>' +cast( measurementdate as nvarchar(12) ) + '</Category> ' from MeasurementStatisticsPerUnit

Open in new window

but i just cannot get my head arround XML.
