Nate,

Thanks Wendell. Thinking it over, your simple template
of

will not work, as much as I wish it would, as I am
allowing other elements such as <strong> and <em> and
I could get passed a node set like this

this is bold text

OR this

this is bold text

For both of those cases, they would need to get
wrapped in a p tag in the output.

The test will work for these cases.

If there are any elements that contain non-whitespace text anywhere inside your p, you'll get a wrapper with this test. You just need to decide whether this describes your requirements accurately. For example, maybe if you had

<ul><li>list with one item</li></ul>

you'd want to strip that p (whereas the test I've given will create a p in output for this). I dunno, it depends on your source and what you're doing with it.

The real point is if you can characterize your requirement more simply, you can write simpler code. Lots of overlapping tests on the presence of certain element types in certain positions make me nervous: a recipe for incompleteness, confusion and breakage under maintenance. To be avoided if possible.

Cheers,
Wendell
