Hi All, If we consider an XML which has multiple namespaces as below ,
<root> <h:table xmlns:h="http://www.w3.org/TR/html4/";> <h:name>Asian Coffee Table</h:name> <h:width>74</h:width> <h:length>129</h:length> </h:table> <f:table xmlns:f="http://www.w3schools.com/furniture";> <f:name>African Coffee Table</f:name> <f:width>80</f:width> <f:length>120</f:length> </f:table> </root> The avro schema should be as follows , { "type" : "record", "name" : "root", "fields" : [ { "type" : "record", "name" : "tableRecord", * "doc" : "http://www.w3.org/TR/html4/ <http://www.w3.org/TR/html4/>",* "namespace" : "http://www.w3.org/TR/html4/"; "fields" : [ { "name" : "name", "type" : [ "null", "string" ] "doc" : "http://www.w3.org/TR/html4/"; } , { "name" : "width", "type" : [ "null", "int" ] },{ "name" : "length", "type" : [ "null", "int" ] }] }, { "type" : "record", "name" : "tableRecord", * "doc" : "http://www.w3schools.com/furniture <http://www.w3schools.com/furniture>",* "namespace" : "http://www.w3schools.com/furniture"; "fields" : [ { "name" : "name", "type" : [ "null", "string" ] } , { "name" : "width", "type" : [ "null", "int" ] },{ "name" : "length", "type" : [ "null", "int" ] }] } ] } When representing this using the Visual DataMapper Editor, in order to differentiate the two records, we can add a namespace prefix to the name of the record as shown below. ​But when generating the Avro Schema, if we pass this value as the name of the node it throws *org.apache.avro.SchemaParseException: Illegal character in: y:tableRecord.* So, if we use only the name (tableRecord, by removing the prefix) to create the avro schema, how are we going to differentiate the records separately when generating the mapping config? eg: If we are to map a field in y:tableRecord with a field in y:tableRecord etc. How can we differentiate this? This usecase of having multiple namespaces can be displayed graphically in the Design view by appending a namespace prefix, but it seems this will have issues in generating the avro schema and the mapping config. Your suggestions are highly appreciated.
