Hello,

I would like to simplify an XMLObject by only retrieving the XMLElements with a specific tag.

I would like a code based with the use of XMLElements as function.

I try this code :

XMLtest3 =  Cases[XMLtest, _XMLElement, Infinity] //. XMLElement[tag : "YO", attributes_, data_] :>  XMLElement[tag , attributes, data]

Definition of the XMLObject:

XMLtest = 
  XMLObject[
    XMLElement["YO", {}, 
      {XMLElement["YO", {}, 2], 
         XMLElement["BA", {}, 
           {XMLElement["YO", {}, 
             {XMLElement["BA", {}, 2]}], XMLElement["BA", {}, 2]}]}]]

I would like to keep only the XMLElements with the tag "YO" and to preserve a tree structure for the XMLObject.

May you help me to correct the code given?

Thank you for your help
