[Xerte] Re: address CDATA?

[Julian Tenney]

It's how xmlToObject handles it: it's basically creating an array / object based on the names it finds in the xml: it finds a CDATA node and rather than create

myNode[0].CDATA[0].text it creates myNode[0].text.

Just the way it functions I guess.

I can.
I'm just curious why I can't get at it.

I tried a couple variations on the firstChild.nodeValue thing and couldn't get that to work either.


It just seems dopey that if for instance I'm receiving a dynamic xml structure back from a server call that I can do


sometextid.setText(interfaceData.pages[0].page[0].id); // an attribute


or



remove the CDATA tags and have setText work correctly.



but if I encounter CDATA tags in the data I'm forced to recast type?

Not sure. From the xml directly it's via firstChild (it see the CDATA as a child node), but xmlToObject obviously drops the object itself into the array.

But this isn't the problem: if it were reporting 'object' then you'd see 'object' on the screen, not undefined.

Why can't you re-cast it?

:-) Yes I know I can recast it.


But how do I get directly to the string within the CDATA tags?


debug( interfaceData.pages[0].page[0].intro_text[0]) // shows "blah" in the debug window
debug(typeof interfaceData.pages[0].page[0].intro_text[0]) // reports "object"




sometextid.setText(interfaceData.pages[0].page[0].intro_text[0]);


Says undefined on screen  (because it's reporting as an object?)

String(your[0].expression[0].here);

Senior moment.


What's the syntax for addressing the CDATA content so it comes out as typeof = string?




<content>
<pages>
   <page id="1">
      <intro_text>
-                 <![CDATA[blah]]>
          </intro_text>






interfaceData = ifc.templateData.content[0];


debug(typeof interfaceData.pages[0].page[0].intro_text[0]);
//gives me "object"


How do I get at the string directly?
I know I could put it in a variable and re-type it, but I want to set text directly:


sometextid.setText(interfaceData.pages[0].page[0].intro_text[0]);
//displays undefined - because it's an object
