Class XlsxParser

java.lang.Object

io.keikai.importer.XlsxParser

public class XlsxParser
extends Object

A StAX parser to convert Xlsx to JSON format.

The syntax as follows

1. All are attributes:

   For example,

   <foo a="a"/>
    

   Result:

   
    {
        "foo": {
            "a": "a"
        }
    }
    

2. Attributes and child element:

   For example,

   <foo a="a">
        <bar>baz</bar>
    </foo>
    

   Result:

   
    {
        "foo": {
                  "": ["a"], // store for the attr key info
                  "a": "a",  // attribute
                  "bar": {
                 "_": "baz" // text only
                  }
        }
    }
   

3. Attributes and text node only:

   For example,

   <foo a="a">bar</foo>
    

   Result:

   
    {
        "foo": {
            "a": "a", // attribute
            "_": "baz" // text only
        }
    }
   

4. Text node only:

   For example,

   <foo>bar</foo>
    

   Result:

   
    {
        "foo": {
            "_": "baz" // text only
        }
    }
   

5. Child element and text node only:

   For example,

   <foo><bar>baz</bar></foo>
    

   Result:

   
    {
        "foo": {
                  "bar": {
                "_": "baz" // text only
                  }
        }
    }
   

6. Multiple child elements with the same key:

   For example,

   <foo><bar a="a"></bar><bar b="b"></bar><baz/></foo>
    

   Result:

   
    {
        "foo": {
            "bar": [{
                       "a": "a"
                   }, {
                 "b": "b"
                   }],
            "baz": null // self-closed tag
         }
    }
