What is BadgerFish?

BadgerFish is a convention for translating an XML document into a JSON object. Once you've got your XML document represented as a JSON object, it's easy to manipulate from within Javascript. If you're familiar with PHP's SimpleXML extension, think of BadgerFish as aiming for a similar goal: making it simpler to do common manipulations of XML documents with a predictable structure.

How does it work?

Here are the rules:

  1. Element names become object properties
  2. Text content of elements goes in the $ property of an object.

    <alice>bob</alice>

    becomes

    { "alice": { "$" : "bob" } }

  3. Nested elements become nested properties

    <alice><bob>charlie</bob><david>edgar</david></alice>

    becomes

    { "alice": { "bob" : { "$": "charlie" }, "david": { "$": "edgar"} } }

  4. Multiple elements at the same level become array elements.

    <alice><bob>charlie</bob><bob>david</bob></alice>

    becomes

    { "alice": { "bob" : [{"$": charlie" }, {"$": "david" }] } }

  5. Attributes go in properties whose names begin with @.

    <alice charlie="david">bob</alice>

    becomes

    { "alice": { "$" : "bob", "@charlie" : "david" } }

  6. Active namespaces for an element go in the element's @xmlns property.
  7. The default namespace URI goes in @xmlns.$.

    <alice xmlns="http://some-namespace">bob</alice>

    becomes

     

    { "alice": { "$" : "bob", "@xmlns": { "$" : "http:\/\/some-namespace"} } }

  8. Other namespaces go in other properties of @xmlns.

    <alice xmlns="http:\/\/some-namespace" xmlns:charlie="http:\/\/some-other-namespace">bob</alice>

    becomes

     

    { "alice": { "$" : "bob", "@xmlns": { "$" : "http:\/\/some-namespace", "charlie" : "http:\/\/some-other-namespace" } } }

  9. Elements with namespace prefixes become object properties, too.

    <alice xmlns="http://some-namespace" xmlns:charlie="http://some-other-namespace"> <bob>david</bob> <charlie:edgar>frank</charlie:edgar> </alice>

    becomes

     

    { "alice" : { "bob" : { "$" : "david" , "@xmlns" : {"charlie" : "http:\/\/some-other-namespace" , "$" : "http:\/\/some-namespace"} } ,

    "charlie:edgar" : { "$" : "frank" , "@xmlns" : {"charlie":"http:\/\/some-other-namespace", "$" : "http:\/\/some-namespace"} },

    "@xmlns" : { "charlie" : "http:\/\/some-other-namespace", "$" : "http:\/\/some-namespace"} } }

     

    What's broken and/or left to do?

    1. BadgerFish throws away the text content of elements if the text content is entirely whitespace. It also doesn't provide a way to get the different text bits in an element whose content is a mix of text and children (e.g. <p>Some text <strong>is important</strong>.</p>). Perhaps those different text bits should be made available in $1$2, etc.
    2. BadgerFish populates @xmlns in all elements where a namespace is active, not just in the elements where the namespace is declared. This may be overkill for people who don't care that much about namespaces. Perhaps allow a format that ignores @xmlns altogether?
    3. Adaptors to create BadgerFish-formatted JSON strings in languages other than PHP.
    4. Adaptors to turn BadgerFish-formatted JSON objects back into XML-formatted strings and/or DOM objects.

You can see an example below:

The American Heart Association endorses thе National Cholesterol Education Program (NCEP) guidelines fоr detection оf high cholesterol: All adults age 20 or older ѕhould hаvе a fasting lipoprotein profile — whіch measures total cholesterol, LDL (bad) cholesterol, HDL (good) cholesterol and triglycerides — oncе еvеrу fіvе years. This test іѕ dоnе аftеr а nine- tо 12-hour fast withоut food, liquids or pills. It gіveѕ information аbоut total cholesterol, LDL (bad) cholesterol, HDL (good) cholesterol and triglycerides.

Your test report wіll show yоur cholesterol levels in milligrams рer deciliter of blood (mg/dL). To determine hоw уour cholesterol levels affect уоur risk of heart disease, your doctor wіll аlѕo tаkе іnto account оther risk factors suсh аѕ age, family history, smoking аnd high blood pressure.
