I am trying to parse xml data to Kotlin/Java and can't figure out how to do it properly. Simpleframework throws
org.simpleframework.xml.core.PersistenceException: Constructor not matched for class openaire.model.Publication
which doesnt really help.
XML:
<response> <header> <size>60</size> <page>1</page> <total>116600160</total> </header> <publications> <publication> <openaireid>od______1318::206c086e81631b3cde0eca4acb2d0ea2</openaireid> <doi>10.22337/1524-5845-2016-12-3-104-113</doi> <doi>10.22337/1524-5845-2016-12-3-104-113</doi> <description>Peer reviewed</description> <publicationtype>Article</publicationtype> <title>Neuroleptiques à uridol (R16341)</title> <authors> <author>Bobon, Jean</author> <author>Mélon, Jean</author> </authors> <dateofacceptance>1970-01-01</dateofacceptance> <sourcejournal>Crossref</sourcejournal> <sourcejournal>Neuroleptiques</sourcejournal> <webresource>http://ijccse.iasv.ru/</webresource> <webresource>https://academic.microsoft.com</webresource> <bestlicense>OPEN</bestlicense> </publication> ..... </publications> </response> Kotlin Class: I think the error might be in the Element lists doi, source journal or web resource.
