I have been following the instructions here: https://www.codenameone.com/javadoc/com/codename1/io/JSONParser.html to retrieve a value from a json file. I have managed to read the top level value of my json content - however I cannot see how to read the value of a nested tag e.g. using this file ...
{
"glossary":{
"title":"example glossary",
"GlossDiv":{
"title":"S",
"GlossList":{
"GlossEntry":{
"ID":"SGML",
"SortAs":"SGML",
"GlossTerm":"Standard Generalized Markup Language",
"Acronym":"SGML",
"Abbrev":"ISO 8879:1986",
"GlossDef":{
"para":"A meta-markup language, used to create markup languages such as DocBook.",
"GlossSeeAlso":[
"GML",
"XML"
]
},
"GlossSee":"markup"
}
}
}
}
}
Please can someone show me how to get to the value of "para" above?
Thanks
After parsing your json data based on this, you can use Result
to read deep into the json content:
import com.codename1.processing.Result;
...
Map<String, Object> data = json.parseJSON(r);
Result result = Result.fromContent(data);
String id = result.getAsString("glossary/GlossDiv/GlossList/GlossEntry/ID");
String para = result.getAsString("glossary/GlossDiv/GlossList/GlossEntry/GlossDef/para");
