Subject RE: [OT] uneven tags inside XSLT conditionals
Date Sun, 31 Mar 2002 16:58:10 GMT
You should rephrase your loop as two loops. In java it would be:

for(int i=0; i<count; i+=columns){
  <tr>
    for(int j=0; j<columns & element-exist; j++){
      <td>
        <element/>
      </td>
    }
  </tr>
}

This is possible in XSLT.

Vadim
