Join Joe Marini for an in-depth discussion in this video Proper XML syntax, part of XML Essential Training (2014).
…XML syntax is a little more strict than what you…might be used to if you're used to working with HTML.…So, let's cover the basic rules of XML syntax here.…First, XML documents must have a single root tag.…They have to have one, it's required.…And if you remember back to the business card example,…the BusinessCard tag was the root tag in that particular document.…XML documents…must also be what's called well-formed.…In other words, there are certain syntax rules that XML documents have to meet.…
The first one is that empty tags had to…be closed with a slash before the closing angle bracket.…Now, this is different from HTML, for example, where image…tags are empty, but they don't have that trailing slash.…And the reason is because the browser knows what HTML is.…It knows there's a tag called image, and it knows…that it's empty.…XML, however, remember, you get to make up your own tags.…And the program that's parsing the XML may not know what your tag is.…So you have to indicate that a particular tag is empty…
