Problem

A Forum reader recently asked:

"I have a eDirectory Container with 1000's of Groups. I have a RegEx String to match - *Marketing-Man.* - with the GroupName in that eDirectory Container in order to get the DN for a matched Group.

I want to traverse all the Groups in a specified eDirectory Container one by one, and perform a RegEx match operation on the current Group."

And here is the response from Father Ramon ...

Solution

If your regular expression is a simple one, you could just do a query on CN using wildcard character "*" and then loop on it. For example:

<do-for-each>
  <arg-node-set>
   <token-query class-name="Group" datastore="src" scope="subordinates">
  <arg-dn>
   <token-text>org\mygroups</token-text>
  </arg-dn>
  <arg-match-attr name="CN"/>
</token-query>
  </arg-node-set>
  <arg-actions>
   <do-set-local-variable name="current-group-dn" scope="policy">
    <arg-string>
     <token-xpath expression="$current-node/@src-dn"/>
    </arg-string>
   </do-set-local-variable>
   <do-trace-message>
    <arg-string>
     <token-text xml:space="preserve">Processing group: </token-text>
     <token-local-variable name="current-group-dn"/>
    </arg-string>
   </do-trace-message>
  </arg-actions>
</do-for-each>

If you really do need a real regular expression, then it is only slightly more complicated:

<do-for-each>
  <arg-node-set>
<token-query class-name="Group" datastore="src" scope="subordinates">
  <arg-dn>
   <token-text>org\mygroups</token-text>
  </arg-dn>
  <arg-match-attr name="CN"/>
</token-query>
  </arg-node-set>
  <arg-actions>
   <do-set-local-variable name="current-group-dn" scope="policy">
    <arg-string>
     <token-xpath expression="$current-node/@src-dn"/>
    </arg-string>
   </do-set-local-variable>
   <do-set-local-variable name="current-group-name" scope="policy">
    <arg-string>
     <token-parse-dn length="1" start="-1"/>
     <token-local-variable name="current-group-dn"/>
    </arg-string>
   </do-set-local-variable>
   <do-if>
    <arg-conditions>
     <and>
      <if-local-variable mode="regex" name="current-group-name" 
op="equal"><same fancy regular expression></if-local-variable>
     </and>
    </arg-conditions>
    <arg-actions>
     <do-trace-message>
      <arg-string>
       <token-text xml:space="preserve">Processing group: </token-text>
       <token-local-variable name="current-group-dn"/>
      </arg-string>
     </do-trace-message>
    </arg-actions>
    <arg-actions/>
   </do-if>
  </arg-actions>
</do-for-each>
