.text() and CDATA

[john]

Currently accessing CDATA contents can be pretty annoying across platforms (IE is different from the rest. .text() should be made to handle these differences.

+1 there should be a crossbrowser solution

I've just re-encountered this. For the curious my workaround is instead of using .text() to use this plugin I created (simply replace .text() with .getCDATA():

jQuery.fn.getCDATA = function() {
	if($.browser.msie)
		return this[0].childNodes[0].nodeValue;

	// Other browsers do this
	return this[0].childNodes[1].nodeValue;
};

It ain't pretty, but in my case did the job.

Are you specifying the dataType in your ajax call? If specified as xml .text() should get you the node text within the CDATA; same goes for the .get method.

$.ajax({

type: "GET", url: "your.xml", dataType: "xml" success: your_function

});

[raccettura]

I'm not specifying a type. The response from the server is application/xml, so jQuery should be treating it as such.

Per the ​docs:

The type of data that you're expecting back from the server. If none is specified, jQuery will intelligently pass either responseXML or responseText to your success callback, based on the MIME type of the response

Based on this, jQuery should correctly handle this.

Now I'm wondering if the bug is in jQuery's detection methods or in it's ability to parse CDATA.

Thanks for taking the time to contribute to the jQuery project! Please provide a jsFiddle that outlines practical use cases for your enhancement request.

Doesn't work for me.

When fetching XML, our server doesn't send the right mime-type,

• if I specify datatype, needs to be browser specific (FF, IE) : 'xml' or 'text/xml' get it the wrong way round => barfs
• neither way parses CDATA correctly...
• whichever datatype is specified, (or if I don't pass the datatype field) data is treated as HTML
• - which works fine... until a CDATA field (which is bad HTML)

Bug

• respect the datatype field, and make it cross browser (i.e. ignore server mime-type if datatype is set)

Workaround

• use datatype plain text
• then convert using "normal" JS

if ( window.DOMParser ) {var parser = new DOMParser(); xml = parser.parseFromString( data, "text/xml" );} else

{ xml = new ActiveXObject("Microsoft.XMLDOM"); xml.async = "false"; xml.loadXML( data ); }

Which leads to a: Feature Request

• add: xml_to_text() and text_to_xml()

Bug mentioned in comment #8 happened in version 1.4.3.

Still valid.

I'd like to see a test case of this with the latest build of jquery

[snover]

Please reopen/comment on this ticket only if you have a valid test case for the latest version of jQuery.
