问题 I am new to NLP and I am looking for a starting point, in terms of some tutorials, documentation or example code.

JAXB Adding attributes to a XmlElement for simple data types

由 a 夏天 提交于 2019-12-23 20:42:07
问题 I want to add some attributes to Xml Elements using JAXB when marshalling from JavaBeans. The Xml Elements are simple data types like String. So I do not want to create new Classes. For example, a desired output would be: <notifications> <date>04/20/2011</date> <subject creditcard_num="22678" checknum="8904">Credit Card Charge Back</subject> <body payment_amount="34.00" return_status="charged back">some text</body> </notifications I do not want to define subject and body as separate classes.
