XML Data Extraction for multiple document types

[eleaese]

I created a simple XML Metadata Extracter, based on the post http://forums.alfresco.com/viewtopic.php?t=7801&highlight=xml+metadata+extraction.

It worked. The context file is recipe-xml-metadata-extracter-context.xml, enclosed.

Now I want to extend to other XML document types. namely Book. I tried with the example included (many-xml-metadata-extracter-context.xml). It worked for Book, but din't work for Recipe.

Could someone tell me how to declare the options in the context file ?

Thank you !

Is Derek Hulley related with those extracters ? Please help us, the example may be trivial but the funcionality is important.

Thank you !
