A source is composed of a list of items that will be parsed to be all displayed on interface in web page. A mapping is used to define a xsltFile and itemXPath to apply on a sourceitems selected by itemXPath. Sometimes, to define itemXPath, namespaces definition are required.

<mapping
  sourceURL="http://info.cri.univ-rennes1.fr/rss/rss.php"
  xsltFile="http://partages.univ-rennes1.fr/files/partages/Services/CRI/SI/conf_lecture_gwe_ray/stylesheet01.xsl"
  itemXPath="/rdf:RDF/default:item">
  <XPathNameSpace prefix="rdf" uri="http://www.w3.org/1999/02/22-rdf-syntax-ns#"/>
  <XPathNameSpace prefix="default" uri="http://purl.org/rss/1.0/" />
</mapping>

Explanations:*

• xsltFile : url of the xslt file used to parse an item
• mobileXsltFile : url of the xslt file used to parse an item in mobile mode - optionnal. If not present xsltFile is also used in mobile mode.
• itemXPath : xpath expression to itemXPath : xpath expression to locate an item in the xml stream source
• element XPathNameSpace : used by itemXPath definition - optionnal
• In order to define which mapping is applied to a particular source some attributes are used (by priority order):

• • sourceURL : url of the source, key entry of this mapping
  dtd :
  • (example: sourceURL="http://info.cri.univ-rennes1.fr/rss/rss.php")
  • dtd : dtd of the source
  , key entry of this mappingxmlns : xml namespace
  • xmlType : xmlType of the source
  , key entry of this mapping
  • xmlns : xml namespace
  xmlType : xmlType
  • of the source
  , key entry of this mapping
  • rootElement : rootElement of the source
  ,key entry of this mapping

Priority to find xslt informations on key entry of a mapping are : sourceURL, DTD, xmlType, xmlns and finally rootElement.
