What is the difference between XML and HTML tags?


Recommended Posts

XML doesn’t tolerate syntax errors. HTML does, with specifications on to correct them.

XML tags have to be closed. They can auto-close, like <stuff/> which is equivalent to <stuff></stuff>. HTML tags that are meant to be empty, don’t need a syntax that closes them.

XML tags’ attribute values have to be quote. It’s <a thing="stuff"> or <a thing='stuff'> but not <a thing=stuff>

XML tags don’t tolerate < other than to open a tag. If you want the text < in XML you need &lt; . In HTML you can use < if it doesn’t look like a correct tag opening.

That’s just the obvious. There are many others.
