We are using Jackson libraries(2.8.3) in our project to read the xml file
and convert into json.
When we read the data using the below code, the parser in the Jackson is
removing the entries in the
nested xml(childs) nodes except the last one node while converting from xml
data to json.
The below is our code and input xml file data:
XmlFactory factory = new XmlFactory();
JacksonXmlModule jm = new JacksonXmlModule();
jm.setDefaultUseWrapper(true);
XmlMapper xmlMapper = new XmlMapper(jm);
JsonParser parser = factory.createParser(new InputStreamReader(new
FileInputStream("bevarages.xml"), "UTF-8"));
TreeNode treeNode = xmlMapper.readTree(parser);
System.out.println(treeNode);
Xml data in the file:(bevarages.xml)
======================
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<itemList>
<LIST>
<e>
<item>
<name>biscut</name>
<type>eatable</type>
</item>
</e>
<e>
<item>
<name/>
<type>drink</type>
</item>
</e>
</LIST>
</itemList>
output produced from the above program is:
=========================================
{"LIST":{"e":{"item":{"name":null,"type":"drink"}}}}
In the above program, the last item from the node itemList is taken and
ignored the first node.
We have done some configuration(setDefaultUseWrapper(true)) using jackson
module to handle the inline xml nodes or arrays properly but no result.
Could any body have any idea, why Jackson parser behaves in this way. Is
there any configuration needs to given to handle the nested nodes.
