Digester / Lucene: How to make the XML parser more filexible ?

[aneuryzma]

I'm using Apache Commons Digester together with Lucene to index a xml
collection. Some fields in the colleciton are not always available. See
example:

    <doc>
    ..
    <geo></geo>
    </doc>
    
    <doc>
    ..
    <geo>
      <latitude>2432</latitude>
      <longitude>2342</longitude>
    </geo>
    </doc>

I'm now wondering how to avoid to get a NullPointerException but only
execute the following lines if the geo tag is available...

    digester.addCallMethod("collection/doc/geo/latitude",    "setLatitude",
0);
    digester.addCallMethod("collection/doc/geo/longitude",   
"setLongitude", 0);

        

thanks
