Extracting meta data

Question

Hi All,
Would it be possible to extract the keywords from a metadata
tag:
<meta name="keywords"
content="wheat,uk,farming,agriculture,milling,feed">
I'm using verity to automatically produce a list of relevant
links based on a set of keywords held in a cfparam:
<cfparam name = "keywords_verity" default =
"wheat,uk,farming,agriculture,milling,feed">
At the moment I have to create the cfparam and copy the
keywords, I would like to be able to extract the metadata and
populate the variable "keywords_verity" dynamically.
Is it possible?
TIA
Trevor

javascript = client-side
cf = server-side
cf processes and serves your page BEFORE js is executed.
for cf to see js vars, they have to be submitted (back) to
the server
(i.e. passed as form or url variables, or thorugh AJAX or
similar way),
so that cf can process them.
if you are trying to populate your cf var with keywords meta
data FROM
THE SAME PAGE you will have to extract the keywords using js
like the
script you have, then, for example, populate a form field
with extracted
data and submit the form to itself. in cf check for existence
of
specified form variable and populate your cf var with that
data.
your could instead write a cf page that will look through a
specified
directory, read each found .cfm/.htm file in it using cfhttp
or cffile
into a variable, which can then be parsed using regex to
extract
keywords if present, which in turn will be saved into your
keywords_verity var or anywhere you want.
