Javascript + XML: Parsing text-only and mixed nodes (into JSON) -

-

i'm working on converting xml document special json format using javascript.

using standard dom processing methods in javascript, need constructing efficient, elegant algorithm determining whether node contains non-text nodes or attributes, , organizing json object differently depending on node contents.

example:

<demo>     <title>text test</title>     <textonly id="demotext">         text-only node! doesn't need 'text' property.     </textonly>     <mixed id="amixednode">         text         <!-- comment node -->         <another />         <!-- note element has not 4, 7 nodes -- counting text between non-text nodes! -->         more text!     </mixed>     <textonly id="specialtext" special="something">         text-only node, it's not because attribute requires create 'text' property     </textonly>     <textonly id="validtext">this text node!</textonly>     <nontext />     <final>end of demo!</final> </demo>

should convert to:

{     title: 'text test',     demotext: 'this text-only node! doesn't need 'text' property.',     amixednode: {         text: [             'this text',             'more text!'         ],         another: null     },     specialtext: {         special: 'something',         text: 'this text-only node, it's not because attribute requires create 'text' property'     },     validtext: 'this text node!',     nontext: null,     final: 'end of demo!' }

notes:

  • all text values trimmed; empty text values removed/ignored

  • multiple text nodes, i.e. when text , other nodes mixed, text stored in array. if there's 1 text value store string.

  • id attributes used property name if present; otherwise node name used. multiple instances of same node name, no id, stored array (but not demonstrated currently).

  • like empty text nodes, comment nodes removed/ignored
