> XMLParser is configurable plugin. It use XPath and namespaces to do the mapping between the XML elements and Lucene fields. 
> Informations :
> 1- Copy "xmlparser-conf.xml" to the nutch/conf dir
> 2- To index your custom XML file, you have to modify the "xmlparser-conf.xml". 
> This parser uses namespaces and XPATH to parse XML content
> The config file do the mapping between the XML noeds (using XPATH) and lucene field. 
> Example : <field name="dctitle" xpath="//dc:title" type="Text" boost="1.4" /> 
> 3- The xmlIndexerProperties encapsulate a set of fields associated to a namespace. 
> If the namespace is found in the xml document, the fields represented by the namespace will be indexed.
> Example : 
> <xmlIndexerProperties type="filePerDocument" namespace=" http://purl.org/dc/elements/1.1/">
>   <field name="dctitle" xpath="//dc:title" type="Text" boost=" 1.4" /> 
>   <field name="dccreator" xpath="//dc:creator" type="keyword" boost=" 1.0" /> 
> </xmlIndexerProperties>
> 4- It is possible to define a default namespace that will be applied when the parser 
> didn't find any namespace in the document or when the namespace found in the xml document doesn't match with the namespace defined in the xmlIndexerProperties. 
> Example :
> <xmlIndexerProperties type="filePerDocument" namespace="default">
>   <field name="xmlcontent" xpath="//*" type="Unstored" boost="1.0" /> 
> </xmlIndexerProperties>
