  Hi, namespaces are supported by the XML Path Reader.
  
  An examaple:
  
  <xml xmlns:xsi="http://www.xxx.org/p/">
  <test xsi:type="a:IntlAddress">test data</test>
  </xml>
  
  <Context xpath="/xml" outPort="0" namespacePaths="xsi='http://www.xxx.org/p/'">
  <Mapping xpath="test/@xsi:type" cloverField="xsiData"/>
  </Context>

  Thanks for your answer.
  
  I am having problems getting this example to work.
  
  I am using...
  
  <OLife xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Party xsi:type="Person">
  <ID>Person_0</ID>
  </Party>
  </OLife>
  
  with...
  
  <Context xpath="/OLife" namespacePaths="xmlns='http://stanlib.com/services/1.0/'">
  <Context xpath="Party/@xsi:type=Person" outPort="0">
  <Mapping nodeName="ID" cloverField="id" />
  </Context>
  </Context>
  
  But get the following error ...
  
  
  Reason: net.sf.saxon.trans.StaticError: XPath syntax error at char 15 in {Party/@xsi:type=Person}:
  Prefix xsi has not been declared
  XML_XPATH_READER0 ...FAILED !
  
  Any ideas what I am doing wrong. Thanks for your help.

  Hi,
  
  This mapping will work...
  
  <Context xpath="/OLife" outPort="0" namespacePaths="xsi='http://www.w3.org/2001/XMLSchema-instance';xsd='http://www.w3.org/2001/XMLSchema';xmlns='http://Mike.com/services/1.0/'">
  <Context xpath="Party" outPort="1" namespacePaths="xsi='http://www.w3.org/2001/XMLSchema-instance';xsd='http://www.w3.org/2001/XMLSchema';xmlns='http://Mike.com/services/1.0/'">
  <Mapping xpath="ID" cloverField="id"/>
  </Context>
  </Context>
  
  with this xml...
  
  <OLife>
  <Party>
  <ID>Person_2</ID>
  </Party>
  </OLife>
  
  but when I use this...
  
  <Context xpath="/OLife" outPort="0" namespacePaths="xsi='http://www.w3.org/2001/XMLSchema-instance';xsd='http://www.w3.org/2001/XMLSchema';xmlns='http://mike.com/services/1.0/'">
  <Context xpath="Party/@xsi:type" outPort="1" namespacePaths="xsi='http://www.w3.org/2001/XMLSchema-instance';xsd='http://www.w3.org/2001/XMLSchema';xmlns='http://mike.com/services/1.0/'">
  <Mapping xpath="ID" cloverField="id"/>
  </Context>
  </Context>
  
  with this xml...
  
  <OLife xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://mike.com/services/1.0/">
  <Party xsi:type="Person">
  <ID>Person_0</ID>
  </Party>
  </OLife>
  
  It doesnt seem to work with the xsi type.
  
  Any ideas?

  Try this:
  
  <Context xpath="/OLife" outPort="0" namespacePaths="'http://mike.com/services/1.0/';xsi='http://www.w3.org/2001/XMLSchema-instance';xsd='http://www.w3.org/2001/XMLSchema'">
  <Context xpath="Party" outPort="1">
  <Mapping xpath="ID" cloverField="id"/>
  <Mapping xpath="matches(@xsi:type,'Person')" cloverField="isPerson"/>
  </Context>
  </Context>
  
  Two points:
  1) The context may not return true/false. But it would be nice feature..
  2) Key sensitive is important for 'http://mike.com/services/1.0/'
