[digester] concatenate multiple elements to a property

[Stefan Burkard <ne...@burknet.ch>]

hi there

i'd like to concatenate multiple strings from several xml-elements (for 
example all "stringelement"-values from the example-xml below) to one 
string and add this string to an objectproperty. is this possible with 
digester? has anybody a tip or a code example for me?

thanks and greetings
stefan

<elementlist>
     <element>
         <string-element></string-element>>
         <other elements></other elements>
     </element>
     <element>
         ...as above
     </element>
</elementlist>

I'm a Digester newbie, but I will take a crack at this because it looks like
something I recently did.

Here is a digester method that would put all of the string-elements into a
StringBuffer and return that StringBuffer.

public static Vector digestDocument(File parseMe) throws IOException,
SAXException {
   Digester digester = new Digester();
  digester.setValidating(false);
    //put a string buffer on the stack
  digester.addObjectCreate("elementlist/element", StringBuffer.class);
    //call the append method on the string-element pattern
  digester.addCallMethod("elementlist/element/string-element", "append", 1);
    //the contents of the tag as the parameter to append
  digester.addCallParam("elementlist/element/string-element", 0);
  return (StringBuffer)digester.parse(parseMe);

 }

You could do something like this to set your object property.

myObject.setObjectProperty(digestDocument(file).toString());

Hopefully this makes sense.
