Re: [Zope] Re: what's the difference between metal:block and tal:block?

...

I'm not understanding when to use either. I sometimes see a tal:block nested in a metal:block, and sometimes the either way, or sometimes just one of the two.

What's the difference between them?

A <metal:block> tag allows you to use METAL statements without having to prefix each attribute with 'metal:', while <tal:block> does the equivalent for TAL statements.

One uses these when there's no obvious or necessary tag in which to put a METAL or TAL declaration. It's quicker to write than a div/span plus a tal:omit-tag. Note that the name of the tag after the namespace (block) can really be anything. But 'block' seems to be our de facto standard. --jcc
