Return type of XMLDom's getElementsByTagName('xxx') ?

Hello,

 

I'm using the XMLDom class to parse some XML. I'm trying to set a variable to a list of tag names that I can loop through later. What is the correct return type I should set 'names' in the following code to?

 

 

names = responseXML.getElementsByTagName('names');

 

I've tried setting it to List<String> but I get the following error:

 

  Error: Compile Error: Illegal assignment from LIST:XMLDom.Element to LIST:String

 

Thanks,

Dan

Hi, 

 List<XMLDOM.Element> is the correct declaration.

getElementsByTagName has a return type of List<Element>. Which means your "names" variable in your code snippet will need to be of the aforementioned type. In your code any time you want to retrieve the string value from your element, you need to use the
 getValue() method on the specific Element object in the List you are creating.

Hi Aish,

 

Thanks for the response. I'm coming from a PHP background so having to declare return types is throwing me for a loop. If I change that line to:

 

 

List<Element> names = responseXML.getElementsByTagName('names');

or

public List<Element> names = new List<Element>();
 
 I keep getting Compile Error: Invalid type: Element 
 
The entire XMLDom class is in my apex classes section which has the Element class in it. This seems like such a basic thing but it's very frustrating.
 
Thanks,
Dan
