    replace the text of an element with tag <bold>

    wolfgangappel

      Dear all,

       

      I want to change the complete text of an element with a certain tag, say "<bold>".

      I can get the tag name via elem.ElementDef.Name. But how do I get the text()-node of the Element.

      Is there something like the xslt text()-node functionality? Some other ideas?

       

      Thanks in advance

          Hi WA,

           

          Good question. There is no concept of a single text node within a FrameMaker element like there is for other DOM tools. But even if there was, there still would be no direct method to set the text. In FrameMaker, you have to deal with element ranges and text selection tools to complete this kind of operation.

           

          Here is a function that replaces the text of the provided element. Hope this helps.

            function replaceElementText(doc, elem, newText)
            {
                //Define a new element range and set it up
                //to represent the contents of the element.
                var er = new ElementRange();
                er.beg.parent = er.end.parent = elem;
                er.beg.offset = 0;
                        
                if(ov(elem.FirstChildElement))
                {
                    er.beg.child = elem.FirstChildElement;
                    er.end.offset = 0;
                }
                else er.end.offset = Constants.FV_OBJ_END_OFFSET;    
                
                //Set the element range in the document and
                //execute Clear() to delete the current element contents.
                doc.ElementSelection = er;    
                doc.Clear(0);
                
                //The insertion point will now be at the beginning of
                //the empty element. Execute AddText() to insert the
                //new text.
                doc.AddText(doc.TextSelection.beg, newText);   
            }

              WA,

               

              I just noticed one thing in my code that won't work for you, that ov() call. That is a personal shortcut to determine the validity of an object. Here is the code:

               

              function ov(obj)
              {
                  if(obj == null) return false;
                  else return obj.ObjectValid();
              }
