xml-ns-parser

A parser for xml that creates a JSON struct which retains all information including attributes and namespaces

structure

Every xml element will be transformed in a JSON object that contains the properties children, attributes, name and scope.

• children
  is an array of the child elements
• attributes
  contains the attributes. Its a attribute-name value map.
• name
  has a local and a namespace property. Where local contains the local name of the element and namespace the namespace
• scope
  contains the mapping of prefixes in xml to actual namespace. Together with the getTagName() function it can resolve prefixes to actuall namespaces.

samlpe

The xml

<test foo='bar' />

will translate to the JSON

{
 "children": [],
 "attributes": {
   "foo": "bar"
 },
 "name": {
  "local": "test",
  "namespace": ""
 },
 "scope": {
  "": ""
 }
}

Notice since the xml did not defined any namespaces the coressponding namespace fileds contain the an empty string.

Or a more complex samlpe that utilise namespaces

<Persons xmlns='https://person.org' xmlns:address='https://address.org' xmlns:age='https://age.org'>
    <Person name='Mike' age='20'>
        <Frind>Paul</Frind>
        <Frind>Sebastian</Frind>
    </Person>
    <Person name='Paul' age='22'>
        <Frind>Mike</Frind>
        <address:street>Main Street 3</address:street>
    </Person>
</Persons>
