Question

I have a dilemma that goes like this.

I have a string that represents XML. I want to manipulate that XML adding and updating nodes, and then I want the xml back as a string.

I have been working with javascript and jQuery and I have looked at several methods

WITH JQuery

var x_raw = "<?xml version='1.0'?><Q id ='23'><SQ id='201'><GP id='0'></GP></SQ></Q>"
var j_xml = $(x_raw)
.... Code for XML manipulation goes here ....
var x_string = (new XMLSerializer()).serializeToString(j_xml);

this produces a security exception in firebug

WITH Straight javascript

var x_raw = "<?xml version='1.0'?><Q id ='23'><SQ id='201'><GP id='0'></GP></SQ></Q>"
var xml = $.parseXML(x_raw);

newNode = xml.createElement("VALUE")
newText = xml.createTextNode("<![CDATA[Whooppeee]]>");

var insert = xml.getElementsByTagName('GP')[0].appendChild(newNode)
insert = insert.appendChild(newText)

var x_string = (new XMLSerializer()).serializeToString(xml);

This works but the CDATA code comes back as

<![CDATA[Whoooppeee]] >

I have tried the javascript escape trick

newText = xml.createTextNode("\<![CDATA[Whooppeee]]\>")

doesn’t work either

WITH jQuery traversal function on an XML Document…

var x_raw = "<?xml version='1.0'?><Q id ='23'><SQ id='201'><GP id='0'></GP></SQ></Q>"
var xml = $.parseXML(x_raw);
var collection = xml.filter("SQ")

produces a firebug error “xml.filter is not a function”
Any jQuery DOM traversal function produces the same error.

I am ready to resort to string manipulation functions which would be ugly!
So any help or hints that get me some logical outcome would very much appreciated.

with much gratitude and appreciation of the collective wisdom of the overflow crew !

Answer 1

Try createCDATASection()

newText = xml.createCDATASection("Whooppeee");
