Mapping Content Anchors to Data Holders

Mapping Content Anchors to Data Holders

A
Content
 anchor stores the text that it extracts from a source document in a data holder. For example, you might configure a
Content
 anchor to store its result in an XML element called
FirstName
. If the
Content
 anchor retrieves the text
Jack
, the Parser produces the following output: 
<FirstName>Jack</FirstName>
More precisely, you might specify that the anchor should store the retrieved text at the path
/Person/*s/FirstName
, which refers to an element defined in the XML schema. The actual Parser output would be: 
<Person>
  <FirstName>Jack</FirstName>
</Person>
On the other hand, suppose that the schema defines
FirstName
 as an attribute of the
Person
 element. You might map the
Content
 anchor to
/Person/@FirstName
. The output would be: 
<Person FirstName="Jack" />
You must map to a data holder that has an appropriate data type. For example, do not map
Jack
 to an XML element that has an
xs:integer
 data type, or to an XML element that has a complex data type containing nested elements. For more information about this rule, see Using Data Types to Narrow the Search Criteria.
