XHTML - What elements are allowed within the element?

Question

I know span strong and em. Are there any others? I\'m trying to filter a text which goes inside a link, and need to know what elements

Answer 1

For HTML 4.01 Transitional, for instance, you can pick the DTD from w3c site. Then search the in the document and navigate the entities, like %inline; to know the allowed nested elements.

• #PCDATA is allowed.
• Through %inline; and %fontstyle;: TT | I | B | U | S | STRIKE | BIG | SMALL
• Through %inline; and %pharse;: EM | STRONG | DFN | CODE | SAMP | KBD | VAR | CITE | ABBR | ACRONYM
• ...and so on

They will, in turn, have other nested elements.

You can repeat the operation for other HTML DTDs.

To know how DTDs nesting rules work, I suggest to read a tutorial.
