Question

My question is I want to check a variable in a xml variable called xmlauthor and I want to check if there is just basically something written on it. How should I do it?
This is what I have written so far:

for num in ic : 
    xmlauthor = dom.getElementsByTagName("author")[0]

    if not xmlauthor: 
        content += "***Changes by:"  + xmlauthor + "*** \n \n"
    else:
        content += "***Changes are made Anonumously** \n \n" 

And here is the error I am getting on my console

content += "***Changes by:"  + xmlauthor + "*** \n\n" 
TypeError: cannot concatenate 'str' and 'instance' objects

Assuming you’re using xml.dom: the getElementsByTagName doesn’t return a list of strings, it returns a list of Element objects, so you can’t concatenate xmlauthor to a string in the line

    content += "***Changes by:"  + xmlauthor + "*** \n \n"

You could convert it to a string by changing it to:

    content += "***Changes by:"  + xmlauthor.childNodes[0].nodeValue + "*** \n \n"
