Question

I am parsing and html/xml file. I am bit confused with the fact that can we have a nested tag like this.

<A a="#" b="#".....<xyz>...</xyz> />

If yes can you please point out me the place where I could get information about this.

Answer 1

No you cannot. Other than the tag name and an optional closing ( /> ) the only thing allowed inside of the tag it self are attributes which take the form key=val. If you want to have < or > in a tag’s attributes then they need to be encoded as < and >

Nested tags have to be done like so

<root>
   <child></child>
</root>

A tag that has a /> is called self closing, this means it has no children
