Question

I am currently working on an xml file for an assignment, but keep on getting a “Extra content at the end of the document” whenever I try to open the xml file in a web-browser, after having spent around an hour and a half on trying to figure out what is causing this, I still have not had any luck, so If someone could help point out the error that I have made or point me in the right direction I would really appreciate it, thanks!
here is the xml content itself

, also here is the error that I keep getting https://i.stack.imgur.com/CRi96.png

Answer 1

look at the error, it tells you exactly. line 4 looks like this:

<client_information xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Access Data_Client Projects_Schema.xsd"/>

followed by the rest of your xml. Except that line is a closed node, so the rest of your xml is being regarded as invalid 🙂 remove the closure at the end, like so:

<client_information xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="Access Data_Client Projects_Schema.xsd">
