@ricardobeat: Great! thank you for your help. I see that there are plenty of manners that can be used to retrieve the type of an element, now it's to choose the good one ;) . I'll use the ternary one for my code but I will also keep in mind the other functions you gave here for using them in my next coding
@Remy: I did that already! ... but when i saw that the ouput was without any tag (stripped), i told myself that the the code won't have been recognized as xml but as text only. If i understand well, the script will parse the html tab and not the output tab ? Again thousand of thanks to all of you here ! you saved me from a violent headache !!
