E4X(ECMAScript for XML)

Revive E4X as EXQO(ECMA-Script's XML Query Object) with SAX added on as methods for the xml object.

With an added method call xPath();

Xml file to be use:

<note>

  <date>2002-08-01</date>

  <to>Tove</to>

  <from>Jani</from>

  <heading>Reminder</heading>

  <body>Don't forget me this weekend!</body>

</note>

Example:

//E4X spec.

var xmlDoc=new XML();
xmlDoc.load("note.xml");
document.write(xmlDoc.body);

//please look at the bottom for a corresponding to this.

//output body text value

Example:

//with added xPath() method
var xmlDoc=new XML();

xmlDoc.load("note.xml");
document.write(

xmlDoc.xPath("//body");

//relative path expression

);

Example:

var xmlDoc=new XML();
xmlDoc.load("note.xml");
document.write(

xmlDoc.xPath("/note/body");

//absolute path expression

);

This will gain attention to the ease of navigating the dom. Also the other goal is to point to xQuery as a server scripting alternative to popular server side scripting such as php.

//thoughts on the E4X spec.

//the e4x spec of the look at this make it to where the root element is the container for the object return.

I feel, this should lean more to JSON type syntax:

var xmlDoc = {

note:[

  {date:"2002-08-01"},

  {to:"Tove"},

  {from:"Jani"},

  {heading:"Reminder"},

  {body:"Don't forget me this weekend!"}

]}

document.write(

xmlDoc.note[4].body);

So let's say we do the same for the spec to make it more... Easy to compose a new spec with.

The dom or really htmlelementobject API and documentobject API both have methods for manipulating the xml/html.

It stand to reason to mimic those feature via JSON.

As so:

var xmlDoc=new XML();
xmlDoc.load("note.xml");
document.write(xmlDoc.note[4].body);

And again with the xPath(/*expression*/); //method

var xmlDoc=new XML();
xmlDoc.load("note.xml");
document.write(

xmlDoc.xPath("/note/body")

);

For the first spec, I say to use only xPath 1.0

With attribute, I say to use the xPath(/*expression*/); method to retrieve that via string:

<date attr="value">

  2002-08-01

</date>

xmlDoc.xPath("/note/@attr");

//xPath 1.0 spec

);

to make the spec easier to adopt.

Making this appliance to "use strict";

I say to make a new statement declaration:

"use EXQO"; or "use ESXQO";

Use JSON syntax when it comes to the EMCAScript environment.

Use xPath(/*expression*/); for all non EMCAScript environment expression, and syntax.

Note that this version may receive further editing in the future.

Thank you for reading.
