simple XSLT question

[madshov]

Hi,

I'm pretty new to XSLT, so my question might be really simple:
How do I get the value og 'subelement Sequence="1"', where 'element Id="NAD01"' is equal to 'MO' in the following XML?

...
<segment Id="NAD">
          <element Id="NAD01">BY</element>
          <element Id="NAD02" Composite="yes">
              <subelement Sequence="1">0987654321</subelement>
              <subelement Sequence="3">9</subelement>
          </element>
</segment>
<segment Id="NAD">
          <element Id="NAD01">MO</element>
          <element Id="NAD02" Composite="yes">
               <subelement Sequence="1">1234567890</subelement>
               <subelement Sequence="3">9</subelement>
          </element>
</segment>
...
 

Thanks,
Mads

you need to dive into XPath (if you have not done yet, you should have a look at the XPath section at W3C)

the XPath you need should probably look like that....

subelement[@Sequence = 1][ancestor::segment/element[@id = "NAD01"]/text() = "MO"]

Thanks! I figured it out!
