Example

The first code section provides sample XML input. The second code section provides an associated XML Mapper configuration that provides two Mapping expressions inside a MappingGroup.

<Document>
  <Tags>
    <Keywords>funny</Keywords>
    <UserTags>hilarious</UserTags>
  </Tags>
</Document>

<XMLMappings>
  <MappingGroup attr="mytags" base-path="//Tags" rec-sep-str=",">
    <Mapping path="Keywords"/>
    <Mapping path="UserTags"/>
  </MappingGroup>
</XMLMappings>

This example will produce a crawled property that has the value funny,hilarious.
