Question

Using XSLT, how can I get all member names associated with the tag A?

    <letter>
      <tag>0-9</tag> 

      <member>
        <name>011</name>
        <type>Member</type>
      </member>

      <member>
        <name>2314</name>
        <type>Member</type>
      </member> 

    </letter>

    <letter>
       <tag>A</tag>

      <member>
        <name>Asia</name>
        <type>President</type>
      </member>

      <member>
        <name>Artie</name>
        <type>Vice 1</type>
      </member>
    </letter>

Use an xpath predicate:

//letter[tag='A']/member
