XMJS

What's XMJS?

XMJS is an XML parsing library for JavaScript. It has a parse and a stringify method, similar to the built-in JSON library and a ton of more features!

Usage / Documentation

Importing

To use this library, you have to first import it by doing the following:

const XML = require("xmjs");

Parsing

For parsing XML, you can run the following:

XML.parse("<ExampleXML>hello world</ExampleXML>");
/*
{
    ExampleXML: {
        value: 'hello world',
        attributes: {}
    }
}
*/

This is how XMJS parses nested tags:

XML.parse("<SupportsNesting><NestedTag>I am a nested tag!</NestedTag></SupportsNesting>");
/*
{
    SupportsNesting: {
        NestedTag: {
            value: 'I am a nested tag!',
            attributes: {}
        }
    }
}
*/

XMJS also supports parsing attributes of tags:

XML.parse("<SomeTag hello=\"world\"></SomeTag>");
/*
{
    SomeTag: {
        value: '',
        attributes: {
            hello: 'world'
        }
    }
}
*/

XML.parse("<Person name=\"Jonathan\" surname=\"Doe\"><Job income=\"500$\"></Job></Person>");
/*
{
    Person: {
        Job: {
            value:'',
            attributes: {
                income: '500$'
            }
        },
        attributes: {}
    }
}
*/

XMJS supports XML arrays since version 1.1.0:

XML.parse(`
<Person name="John">
    <FavoriteFoods>
        <Food>Cheeseburger</Food>
        <Food>Pizza</Food>
        <Food>Broccoli</Food>
        <Food>Doner</Food>
    </FavoriteFoods>
</Person>
`);

/*
{
  Person: {
    FavoriteFoods: {
      Food: [
        {
          value: "Cheeseburger",
          attributes: {}
        },
        {
          value: "Pizza",
          attributes: {}
        },
        {
          value: "Broccoli",
          attributes: {}
        },
        {
          value: "Doner",
          attributes: {}
        }
      ]
    },
    attributes: {
      name: "John"
    }
  }
}
*/

Stringifying

XMJS can stringify JavaScript objects, just like how the JSON.stringify method does it

XML.stringify({
    Person: {
        Name: "Jonathan",
        Surname: "Doe",
        EMail: "john@doe.com",
        Job: {
            Income: "500$"
        }
    }
});
/*
<Person>
    <Name>Jonathan</Name>
    <Surname>Doe</Surname>
    <EMail>john@doe.com</EMail>
    <Job>
        <Income>500$</Income>
    </Job>
</Person>
*/

Validating

XMJS can validate XML through XML.validate:

XML.validate("<Tag>hello world</Tag>"); // Parses and returns { Tag: { value: 'hello world', attributes: {} } }

XML.validate("i am not valid XML"); // Returns false

XML To JSON

XMJS can convert XML data to JSON:

XML.xmlToJson("<Person name=\"Jonathan\" surname=\"Doe\"><Job income=\"500$\">Engineer</Job></Person>");
/*
{
    "Person": {
        "Job": {
            "value": "Engineer",
            "attributes": {
                "income": "500$"
            }
        },
        "attributes": {
            "name": "Jonathan",
            "surname":"Doe"
        }
    }
}
*/

JSON to XML

XMJS can also convert JSON data to XML:

XML.jsonToXml("{ \"Hello\": \"World\" }");
/*
<Hello>World</Hello>
*/
