Alchemy can return html entities as relevant tags

oh whoops, the html that i was trying to quote came through :P

and nbsp have caused me troubles so far.

simple fix:

line 77, just under

<?php
function alchemy_get_elements($text, $type = 'keywords', $output = 'normalized', $cid = 0, $use_cache = FALSE) {
?>

add this:

<?php
$text = strip_tags( $text );
?>

could someone review #4 so we can get it committed?

i find it hard to see how such a simple change could break anything, but someone else might know something i don't about that PHP function.

it is mostly doing what i need, but characters like slashes and html entities are still being sent.

i expanded it to this:

$text = strip_tags( $text );
$text = html_entity_decode( $text, ENT_QUOTES, 'UTF-8' );
$text = str_ireplace( ' ', ' ', $text );

and that got most things that were still annoying me, but when i tried to use a regex to strip everything except "word characters" and white space alchemy sent an error.

now that i think about it, that could have had something to do with me sending a 1000 word "sentence" to alchemy after i stripped out all the punctuation.

anyway, i ran out of time to work on this as it is working fine for 90% of our articles with those three lines i posted above, but if you want to take it further you definitely could.

btw, we've noticed that the quality and relevance of the tags returned by Alchemy in general are vastly improved when you send it plain text with simple punctuation rather than html.
