public class XmlDataSource
extends java.lang.Object
To access data of the corresponding file or stream while assembling a document, pass an instance of this class as a data source to one of DocumentAssembler. assembleDocument overloads.
In template documents, if a top-level XML element contains only a list of elements of the same type, an XmlDataSource instance should be treated in the same way as if it was a DataTable instance. Otherwise, an XmlDataSource instance should be treated in the same way as if it was a DataRow instance. For more information, see template syntax reference(https://docs.groupdocs.com/display/assemblyjava/Template+Syntax+-+Part+1+of+2#TemplateSyntax-Part1of2-UsingDataSources).
When XML Schema Definition is passed to a constructor of this class, data types of values of simple XML elements and attributes are determined according to the schema. So in template documents, you can work with typed values rather than just strings.
When XML Schema Definition is not passed to a constructor of this class, data types of values of simple XML elements and attributes are determined automatically upon their string representations. So in template documents, you can work with typed values in this case as well. The engine is capable to automatically recognize values of the following types:
java.lang.Integer
java.lang.Long
java.lang.Double
java.lang.Boolean
java.util.Date
java.lang.String
Note that for automatic recognition of data types to work, string representations of values of simple XML elements and attributes should be formed using invariant culture settings.
